Researchers have not yet determined whether ADHD itself or medications used to treat it increase a person’s risk of Parkinson’s. However, they do know that those who have ADHD are 2.4 times more likely to develop BG&C diseases like Parkinson’s than those without the disorder.
BG&C diseases cause damage to nerve cells in the basal ganglia that control movement, and they also result in changes in dopamine production. The study examined medical records from 31,769 patients with ADHD and 158,790 people who did not have the condition.

Symptoms of Parkinson’s disease include rhythmic shaking (tremor), stiff muscles, difficulty walking and trouble thinking. Symptoms can come and go, but they’ll usually get worse over time.
The symptoms of Parkinson’s are related to a loss of nerve cells that release the neurotransmitter dopamine, which helps control movement. Treatment with levodopa, or L-DOPA, has helped people with Parkinson’s regain some movement control. But the drug doesn’t cure non-motor symptoms.
A study of medical records found that people who have ADHD are at an increased risk for developing Parkinson’s later in life. The researchers compared healthcare records of 31,769 people with ADHD to those of 158,790 people without the disorder who were matched in age and gender. The patients in the ADHD sample were more likely to take stimulant medications such as amphetamine or methylphenidate than those in the other group. People taking these drugs had a 4 times greater risk of developing Parkinson’s than those not taking them.
Besides tremors, other signs of Parkinson’s include slowed movement, or bradykinesia; weakness that makes it hard to walk, climb stairs or turn in bed; and a change in posture and balance that can lead to a stooped appearance, dizziness or falls. Parkinson’s can also cause a loss of automatic movements, such as blinking or smiling. Your arms may swing when you walk and you’ll have difficulty with writing, or your handwriting may become small. Parkinson’s can also cause bladder problems, including a frequent need to urinate and difficulty with urinating.
Some people with Parkinson’s experience depression or other emotional changes. These can be more severe in people who have had ADHD. Some people with PD also have sleep or bladder problems, which can be made worse by medications used to treat Parkinson’s. In some cases, a combination of treatments can help relieve these symptoms. In addition, doctors can prescribe medicines that boost your dopamine levels to reduce or eliminate the tremors and slow movement. Medications for depression or other mental health issues may also improve these symptoms. In some cases, physical therapy can help with some non-motor symptoms, such as pain or constipation.

Researchers have found that people who have been diagnosed with ADHD are more likely to develop Parkinson’s disease later in life. This is probably due to the fact that both disorders affect the same areas of the brain, the basal ganglia and the cerebellum. These are important areas that control motor functions, behaviors and impulsivity. Both disorders can be treated with drugs that are designed to increase the levels of dopamine in the brain. Whether or not these medications can prevent Parkinson’s is still unclear.
Parkinson’s is a neurodegenerative disorder characterized by both motor and non-motor symptoms. The motor symptoms include tremors at rest, bradykinesia and postural instability. The non-motor symptoms are related to cognitive decline, sleep disorders and autonomic dysfunctions. In recent years, there has been increased interest in the connection between PD and impulsive behavior, particularly the tendency to engage in compulsive behaviors that lead to immediate rewards such as gambling, buying, eating and sexual behaviour.
Research has also shown that impulsive behaviors are associated with decreased functioning and higher levels of depression in people with PD. This is likely because the dopamine system involved in impulsive behavior is impacted by the same chemical changes seen in PD. Therefore, it is not surprising that people with PD who have a history of ADHD may be more prone to developing impulsive behaviors.
A recent study has reported that those who have been diagnosed with ADHD are more than twice as likely to develop a BG&C disease (including Parkinson’s) than people without a diagnosis of ADHD. This is especially true if the person had been prescribed stimulant medication for ADHD.
The researchers used the Utah Population Database to examine records for more than 190,000 people who had been diagnosed with either ADHD or another BG&C disease. Of those, 152 went on to develop Parkinson’s disease. The results showed that those who had been diagnosed with ADHD had a 2.4-fold greater risk of developing Parkinson’s than people without a diagnosis of ADHD. The risk was even greater in those who had been prescribed amphetamine or methylphenidate-based psychostimulants for their ADHD.

ADHD affects parts of the brain called the basal ganglia and cerebellum. These areas control movement and require healthy levels of dopamine to function properly. Researchers have found that people who have ADHD may be at a higher risk of Parkinson’s disease and other disorders of the basal ganglia and cerebellum than those without the condition. They also have a greater chance of developing these disorders earlier in life than those who do not have the disorder.
This higher risk is likely due to the fact that the drugs prescribed for ADHD, which are called psychostimulants, alter and can damage dopamine signaling pathways. The researchers found that people who had been diagnosed with ADHD were more than twice as likely to be diagnosed with Parkinson’s or other BG&C diseases (which include primary parkinsonism, secondary parkinsonism and essential tremor) than those without the disorder. This was true even after taking into account factors such as age, sex, psychotic conditions and tobacco use.
The researchers analyzed medical records from the Utah Population Database to determine whether those diagnosed with ADHD or who had been treated for the disorder with methylphenidate and/or amphetamine had a greater chance of developing PD than those without the condition. They compared data from 4,960 people who had been given ADHD medication with the records of 1,091 individuals who had not received ADHD medications or a diagnosis of PD. They then determined whether there was a causal association between the two groups using genetic correlation and Mendelian randomization techniques.
The study found that the participants who were given atomoxetine, a drug that is already approved for use in the United States to treat ADHD, were more successful at controlling their impulsive behavior than those who did not take the medicine. This suggests that if the right medication can be developed, this type of treatment could help people who have ADHD lower their risk of developing Parkinson’s. This is important because there are no effective treatments for the disease at this point. This type of research is vital for the advancement of Parkinson’s treatments and can give doctors a better idea of what to look out for when treating their patients with the disease.
Oren Zarif
Many people with ADHD get better with the help of medication, including stimulants. These drugs may be able to reduce symptoms in some people with Parkinson’s as well. However, more research is needed to understand how these medications might work together. Some experts believe that the link between ADHD and Parkinson’s is due to the fact that both disorders affect areas of the brain called the basal ganglia and the cerebellum. Both areas require healthy amounts of dopamine to function properly.
A 2021 study found that people with ADHD are at a greater risk of developing diseases that affect the basal ganglia and cerebellum, such as Parkinson’s, than people without the disorder. The researchers looked at medical records from 31,769 people with ADHD and 158,790 people without the disorder who were the same age and sex. They controlled for factors that increase a person’s risk of developing Parkinson’s such as smoking, psychotic conditions and drug/alcohol abuse. The researchers also looked at whether the people with ADHD had been prescribed amphetamine salts, methylphenidate or both. In 4,960 people with ADHD who had been prescribed stimulant medications, the researchers found that they were at an 8.6-fold increased risk of developing BG&C diseases compared to those without ADHD.
This increased risk is thought to be caused by the same neurotoxic effects that cause people with ADHD to develop PD. Stimulants bind to and strongly attach to dopamine receptors (D1, D2 and D5). Different stimulants attach to different receptors, and different people respond differently to each drug. Similarly, Parkinson’s medications like levodopa (L-3,4-dihydroxyphenylalanine) and carbidopa (levotyl) bind to and weakly attach to D1 and D5 dopamine receptors.
In addition to dopamine agonists, some people with Parkinson’s are prescribed anticholinergic medications such as amantadine (Symmetrel) and guanfacine (Intuniv). These drugs have been shown to improve cognitive and non-motor PD symptoms. They do not treat the underlying neurodegeneration, but they may delay the onset of the disease by a few years. They are also useful in reducing the risk of developing a motor complication of the condition known as dyskinesia.
Oren Zarif
A lack of dopamine disrupts the coordination between nerve and muscle cells. This leads to movement problems, such as tremors.
Your neurologist will probably recommend medication to control your symptoms. But it may take time to find the right medicine and dosage for you.
Clues to Parkinson’s often show up before physical symptoms do, such as loss of smell, a sleep disorder called REM behavior disorder and depression.
Oren Zarif
Tremor, or shaking, is the first symptom of Parkinson’s that many people notice. It often happens in one arm or hand, and then moves to the other side of the body over time. It may also affect the chin, face or legs. It can be mild and go away on its own, or it can get worse. It can become more noticeable during times of stress or excitement. It is not a sign of dementia, but it can make it difficult to write or speak clearly. Some medications can help reduce the tremor.
In addition to tremor, PD patients experience non-motor (non-movement) symptoms like fatigue and depression. Some of these symptoms appear years or even decades before motor tremors do, and can be hard to connect with the tremors. Other signs include a feeling of urgency to urinate, difficulty sleeping due to REM sleep behavior disorder and loss of sense of smell (anosmia).
Resting tremors are common in Parkinson’s. These tremors occur while your muscles are at rest, such as when you’re sitting or standing still (hence the name). They tend to be less severe than tremor that happens during movement. You may also experience pill rolling tremors, which resemble the circular motion of rolling a pill in your fingers. You may also have a tremor that only occurs when holding a particular body part against gravity, called orthostatic tremor.
People with tremors who don’t have Parkinson’s should see their doctor. They can find out the cause and treat it if needed. It’s important to rule out other conditions that could be causing the tremor, such as essential tremor. The tremor in these cases gets better when your muscle is not moving and it can be reduced with medication, lifestyle changes and meditation techniques.
Oren Zarif
Stiffness is the main problem in Parkinson’s and usually affects the shoulder, arms and legs. It’s caused when nerve cells in the basal ganglia, an area of the brain that controls movement, become impaired or die. This results in less dopamine being produced.
This leads to a decrease in mobility, which can result in problems such as difficulty walking and wearing clothes. It can also cause problems like facial masking, which is when the muscles of the face become rigid and look like a mask.
Other symptoms of Parkinson’s include constipation, which is often caused by medicines used to treat the disease. People may also experience changes to their sense of smell and fatigue. Constipation can sometimes be a symptom of Parkinson’s before tremors start to develop.
Another symptom is unsteady posture, which can affect both standing and sitting. This can lead to falls and pain in the feet and legs. Some people with PD can develop a dragging, scuffled gait (called’shuffling’), which can make it difficult to get their feet under them when they walk. They can also freeze when they’re moving, which is a common symptom of Parkinson’s and can increase the risk of falling.
There are ways to manage stiffness and improve the way you move, including exercise, which can help stretch and loosen the muscles. It’s important to speak to your GP, specialist or Parkinson’s nurse about this because they can advise you on what exercises are best for you. You can also take medication that can help to relieve stiffness, such as levodopa or a combination of other drugs. Regularly stretching your muscles is also helpful and can be done in many ways, such as in the shower or when you’re sitting down watching TV or reading.
Oren Zarif
Difficulty walking is a common symptom of Parkinson’s disease. This can be caused by changes to the muscles in your legs, ankles, knees, hips or spinal cord and even to the brain and inner ear. This can make it harder to control your body movement and increases your risk of falling.
Difficilety walking can be due to the loss of dopamine-producing cells in a part of your brain. As a result, your muscles become stiff and you can’t move as easily or quickly. You may also have a shuffle-like gait, a soft or slurred speech and a stooped posture. This can make it hard to walk or get up from a chair and affects your balance and puts you at risk of falls.
Freezing is a sudden short episode of being unable to move your feet forward despite trying to do so. This is sometimes called festination. This can cause you to crash into obstacles in your path or into furniture. People with PD who experience freezing often describe that it happens when they are trying to turn a corner or enter a doorway.
Often the problem with freezing is due to the ‘on/off’ cycle of your Parkinson’s medications. Discussing your medication with your GP and specialist is important to manage this issue. It is also advisable to seek the help of a physiotherapist who can provide you with a personalised assessment and treatment program.
Often when people say they feel weak all over, they are describing the non-motor symptoms of PD such as fatigue and a general sense of unsteadiness. However, some of the motor or gait symptoms of PD could be responsible for this feeling of weakness including bradykinesia, gait disorder and freezing.
Oren Zarif
Difficulty talking is a common symptom of Parkinson’s disease. Many people with PD start out with slurred speech, which may become more pronounced as the condition progresses. They may also have difficulty pronouncing words and articulation. This can cause their friends and family to misinterpret them as a lack of interest in conversation, aloofness or even depression.
Difficulties with swallowing (dysphagia) can also occur with PD. Swallowing problems are a serious complication because they can lead to weight loss, choking and food entering the lungs. People with PD should let their healthcare providers and/or a speech-language pathologist know as soon as they notice swallowing difficulties.
A plethora of options are available to help people with speech and swallowing difficulties. Your healthcare provider will be able to recommend assistive devices and a speech-language pathologist for further evaluation.
Slurred speech and swallowing difficulties are difficult for everyone involved. But they can be especially frustrating for people with a cognitive condition like Parkinson’s. They often feel isolated and frustrated, which can lead to stress and depression. They are often forced to use nonverbal communication, such as hand signals and facial expressions to communicate with others.
In addition to recommending assistive devices, a speech-language pathologist can teach you strategies that can help you conserve energy and improve your ability to speak clearly. They can also show you how to use the device that best fits your needs. They can also teach you ways to use your voice more efficiently, such as using a whispered or soft tone. MJFF is working toward better therapies to address these challenges. You can join a clinical study to learn more about the latest advancements by visiting Fox Trial Finder.

Depression is a serious mental health condition that affects your mood and emotions. It can cause feelings of sadness, hopelessness and worthlessness that interfere with your daily functioning. Depression can also make it hard to think clearly and feel energized. People with PD often experience depression because of the way Parkinson’s disease changes their brains. PD damages nerve cells in the basal ganglia, causing them to stop producing dopamine, a chemical that carries messages between nerve cells. Without enough dopamine, the brain can’t control movement-related symptoms like shaking and stiffness. The loss of dopamine in the brain also causes non-motor symptoms such as depression, hallucinations and sleep problems.
You may be able to manage your symptoms through lifestyle changes, medicine and therapy. Talk to your doctor if you’re worried about depression. He or she can screen you for depression and prescribe antidepressant medicines if needed. You can also get support from friends and family, join a Parkinson’s support group or take part in online discussion forums.
People with PD are more likely to have depression than those who do not have the disorder. Symptoms of depression can be hard to distinguish from the typical tremors associated with PD, so it is important to tell your doctor about them. Your doctor will also want to ensure that you are taking your PD and depression medications properly so that they do not interact with each other. The National Institutes of Health recommends that you eat well, exercise and get enough sleep. You should also avoid alcohol and recreational drugs because they can make depression worse. If you’re interested in trying psychological therapy, look for an approach that focuses on changing patterns of thought and behavior to ease depression and anxiety.
Oren Zarif
Most people with PD develop stiff muscles and inflexibility (rigidity) that make movement slower. This is called bradykinesia. It can also mean that everyday tasks take longer to do.
Other symptoms of Parkinson’s disease include a feeling of fatigue that doesn’t go away even with rest, a dry mouth, drooling and bladder problems like frequency and urgency. Medicines can help with these symptoms, but each person’s medication needs are different.
Oren Zarif
Tremor is a common symptom of Parkinson’s disease, but it’s important to distinguish it from other causes, like stress or fatigue. Tremors also can be caused by certain medications, including antipsychotics and some antidepressants. If you have a tremor, it’s best to talk to your doctor about treatment options. Tremors tend to decrease with time, but it’s difficult to predict how long that will take.
Some people with Parkinson’s disease develop tremors that are most noticeable when they’re not using their hands. These are called resting tremors. They’re typically asymmetrical and have low frequency, such as 4 to 6 Hz. You can also experience a tremor in the hand while you’re holding something, such as a cup or paper. This is known as a kinetic or intention tremor. Intention tremors usually become worse as you get closer to the object.
Other types of tremor include postural tremors (which affect the head or lower limbs while standing), cerebellar tremors, and writing tremors. Depending on the type of tremor, you may notice other symptoms associated with Parkinson’s, such as a stooped posture or slow movement while walking. You might have difficulty turning your head while speaking, and you might find it hard to blink or write. You might also have trouble swallowing and experience drooling, which happens due to loss of muscle control.
The tremors of Parkinson’s disease occur when the basal ganglia in your brain become damaged. It’s thought that this damage is the result of a buildup of the protein alpha-synuclein, which leads to a misfolded form of the protein. A test that looks for these proteins in cerebrospinal fluid can determine whether you have Parkinson’s disease. The test involves a spinal tap, in which your healthcare provider inserts a needle into your spine to collect cerebrospinal fluid. A skin biopsy can also look for these proteins.

A stiff neck or back can feel like it’s from an injury or just getting old, but the stiffness you experience may be part of your Parkinson’s disease. Rigidity is one of the most common motor symptoms, and 90% of people with Parkinson’s have it at some point. It happens when the muscles used to flex and extend your joints become very tight, like a lead pipe. It can be painful, limit your range of motion and make movement more difficult.
Rigidity can lead to other symptoms, including loss of automatic movements, like blinking or swinging your arms when you walk. Your speech may slow down, slur or become monotone. You can lose your sense of smell and have trouble sleeping. You might thrash around in bed or have quick jerks while you’re asleep.
It’s normal to have tremors when you move, but if you notice that your tremors are more constant or don’t go away when you stop moving, talk to your doctor. The same is true if you have a hard time standing up from a chair, or if you seem to be stooped over or unable to keep your balance when you stand up.
Your doctor will ask about your symptoms and do a physical exam, including a range of motion test. They might also order imaging tests if they suspect damage to bones, joints, tendons or ligaments. They might also take a blood sample or do a brain scan to see how your nerve cells are working. They may also give you a medication that can help control your tremors or stiffness. They may also recommend a therapy to improve your flexibility, like stretching.
Oren Zarif
Difficulty swallowing (dysphagia) is common in PD, and it can worsen as the disease progresses. It can be caused by muscle rigidity and bradykinesia, as well as problems with the nerves or muscles that help you swallow. This makes it difficult to eat and drink enough food and fluids to stay healthy. It also increases your risk of aspiration — inhaling food or liquid into the lungs, which can cause pneumonia. Symptoms of swallowing trouble include trouble chewing or gulping, drooling when you swallow, loss of weight and difficulty breathing.
Dysphagia is a symptom that can be caused by any disease or condition that affects the nerves or muscles that help you swallow. It can occur with brain tumors, head injuries or strokes, spinal cord disorders such as multiple sclerosis and muscular dystrophy, amyotrophic lateral sclerosis, or movement disorders like tremors and dystonia. Some medications can also cause dysphagia, including anticholinergics (such as trihexyphenidyl and tetrabenazine) and certain antidepressants.
Sometimes, simple changes in diet or medication can help ease swallowing difficulties. Your doctor can refer you to a speech pathologist to teach you techniques to make it easier to eat and drink. They may recommend exercises to strengthen your swallowing muscles and a thicker diet that includes liquids. They can also suggest ways to reduce your risk of choking, such as not using drinking straws or eating small, soft foods that are easily chewed and swallowed. They might even teach you the Heimlich maneuver, which is a series of moves you can do if you experience severe choking. If your swallowing problems are getting worse, talk to your doctor right away. They might want to perform a barium swallow test or endoscopy to look at your esophagus and see what is causing your problem.
Oren Zarif
Loss of balance is another common symptom of Parkinson’s disease. It happens because the millions of nerve and muscle cells that control movement are out of balance with one another. Normally, neurotransmitters like dopamine work in harmony to coordinate movement and help keep your body upright. But when you have Parkinson’s, your dopamine levels are low. This causes tremors (shaking), stiff muscles, slow movements and loss of balance.
The cause of most cases of Parkinson’s is unknown. But the problem is believed to stem from a buildup of a substance in your brain called Lewy bodies, which consists of clumped protein fragments called alpha-synuclein. Some experts think that the abnormal proteins are a result of oxidative stress, environmental toxins and genetic mutations. Other possible causes include head injuries, cardiovascular diseases and certain medications.
People with Parkinson’s often develop a condition called secondary parkinsonism, which is caused by medication side effects or illness. It usually appears after about a year of taking antipsychotic drugs that are used to treat depression or bipolar disorder. The symptoms that occur in secondary parkinsonism are similar to those of Parkinson’s, including tremor; muscle rigidity; slow or slurred speech; and difficulty walking or balance.
One of the most common balance issues associated with PD is freezing of gait, which occurs when you try to walk and are unable to move your feet forward. This symptom can lead to falls, so it’s important to seek treatment for it. Fortunately, physical therapy can help reduce your balance problems and prevent falls. It’s a good idea to start this therapy early, before you have trouble moving. The therapist will teach you exercises that help improve your posture and balance, as well as techniques to reduce the risk of falls.

Difficulty speaking (or dysarthria) is a speech disorder that happens when you lose control of parts of your nervous system that govern how to speak. This can cause your voice to become weak, slurred, breathy or hoarse and can make it difficult to pronounce words. You may also have a reduction in the speed of your speech or an increase in the number of hesitations or pauses.
This is the most common speech symptom of Parkinson’s and affects 70 to 100% of people with the condition. It can make social situations awkward because people don’t know why you slur your words or have trouble understanding what you are saying. It can even lead to feelings of embarrassment. Excessive drooling, or sialorrhea, is another common non-motor symptom of PD that can occur due to swallowing issues, which makes saliva pool in the mouth. This can be uncomfortable and it increases the risk of aspiration, so you should try to keep your saliva levels normal.
Dysarthria can be triggered by damage to certain areas of the brain. This can be developmental, which happens in children due to birth injuries such as cerebral palsy, or acquired, which is usually the result of a stroke or brain tumor. Some medications can also trigger dysarthria, especially those that reduce dopamine levels in the brain.
Your doctor will check to see if your dysarthria is caused by a viral infection or if it is a sign of a serious problem such as carotid artery dissection (which can cause a sudden loss of blood to the head). Your doctor may refer you to a specialist who provides treatment programs, which can help improve the volume and clarity of your voice. A good place to start is with Lee Silverman Voice Treatment (LSVT). This intensive treatment programme combines several therapy sessions together with home practice exercises.

There are no blood or lab tests to diagnose Parkinson’s disease. Doctors usually diagnose it based on your medical history and a neurological exam.
Symptoms include:
Tremor (shaking)
Rigidity (muscle stiffness)
Sleep problems (including REM behavior disorder and restless legs syndrome)
Constipation or urinary incontinence
Changes in your handwriting or writing size (micrographia)
Most people with Parkinson’s take levodopa and carbidopa, which help to improve their symptoms. The doses of these medicines are adjusted based on the severity and individual tolerances of each person.
Oren Zarif
Tremor is a very common symptom of Parkinson’s disease. It is a rhythmic shaking or quivering movement that affects about 80% of people with PD. The shakes may occur at rest or during action, but they usually decrease when you try to move the limb. The shakes also may cause abnormal postures, called dystonia.
The tremors that appear in PD are different from those caused by other diseases. They typically are asymmetrical, with one side of the body affected more than the other. They start in the limbs, especially the hands, but may spread to other parts of the body. They are slower and more rhythmic than a normal tremor, and they tend to be more noticeable.
Some medications can control tremors. But some people develop variations in their response to medication that can cause “motor fluctuations.” During these periods, the drugs don’t seem to be as effective, and uncontrollable writhing movements, called dyskinesias, may occur. If you have these fluctuations, it is important to talk to your doctor about whether the medications are still working for you.
If your tremor isn’t controlled by medications, surgery may be an option. It involves inserting electrodes into a part of your brain called the thalamus. The electrodes send electrical impulses to the brain that can help reduce tremors.
Another option is to take adenosine receptor antagonists. These drugs block the brain’s response to dopamine, which can help lessen tremors. They include istradefylline (Nourianz) and nuplazid (Pimavanserin). Some people who are unable to control their tremors with medication or surgery can benefit from neurosurgical treatment that targets the globus pallidus, subthalamic nucleus, or the thalamus. This involves placing small electrodes into the brain through a tube implanted in the chest.
Oren Zarif
Stiffness is a Parkinson’s symptom that can happen in any part of your body. It occurs when your muscles get stiff and have less flexibility. This can lead to problems with your posture and balance, such as a stooped or hunched over stance. It can also affect your walking, as you may have trouble swinging your arms and take shorter, shuffling steps. It can also make it hard to turn while you’re walking. It can also cause you to blink less often and have cramped or small handwriting (micrographia).
Your neurologist will prescribe medications to manage your symptoms. But they can’t cure the condition, so they’re only meant to help ease the severity of your symptoms. It’s important to keep taking your medication, as it can prevent the symptoms from getting worse.
Other symptoms of PD include constipation, depression and fatigue. You might also experience problems with your sense of smell and a reduction in sexual desire. Parkinson’s can also lead to a change in your voice, which can sound breathy or hoarse. This can sometimes be caused by a cough or cold, but it might be a sign of the disease.
Parkinson’s symptoms are caused by a loss of nerve cells in the area of the brain called the substantia nigra. These cells produce dopamine, which sends messages between this area and the next relay station in the brain to control movement. When these neurons die, you lose the ability to initiate movement and instead have slow, jerky movements. Parkinson’s symptoms usually start on one side of the body and affect it more than the other. But they can eventually spread to both sides of your body.
Oren Zarif
In Parkinson’s disease, balance problems (also called postural instability) worsen as the condition progresses. This is because the brain has trouble quickly regulating blood pressure when you change positions, such as when you move from lying down to standing up or vice versa. This leads to dizziness, faint feelings and falls.
You also may notice changes in your gait, or the way you walk. You may take shorter steps and place your feet closer together when you walk, which can make it harder to keep your balance and increase the risk of falls. You may also start to drag or shuffle your feet when you walk, which makes it harder to turn.
Difficulty with balance can be a major concern because falling is one of the most common reasons for hospital visits and home care. But your neurologist and physical therapist can teach you techniques to help reduce your fall risk.
Many people with Parkinson’s disease have difficulty swallowing or chewing food, especially in the late stages of the condition. You may also have bladder or bowel problems, including urinary incontinence. And you may have sleep problems, such as waking up frequently throughout the night or having trouble falling asleep at night.
Some people with PD have cognitive problems, such as depression and thinking difficulties. These usually occur in the later stages of the condition and aren’t helped by medicines. People with PD may develop an increased risk of skin cancer, particularly melanoma. You should have regular skin exams and watch for any unusual blemishes or lumps. You should also avoid exposure to sunlight or other sources of UV rays. These precautions can help lower your risk of skin cancer and other health conditions, such as a decrease in bone density or heart disease.

Difficulty with coordination is a common Parkinson’s symptom. It can include stiff muscles, slow movements and changes in walking or posture. These symptoms can make it difficult to get out of bed in the morning or hold your arm out when you are eating. In the later stages of PD, you may develop problems with your balance or fall more often. You may also have trouble swallowing and may drool more than usual. Your hands may shake while you are writing, and your handwriting can become small.
Your tremors and slow movement (bradykinesia) can lead to problems with posture, gait and balance. This is called postural instability and can lead to falls. As Parkinson’s disease progresses, you may notice a decrease in the natural swing of your arms when you walk or a shuffling of the feet when you walk (festination).
You may also have difficulties with thinking and memory. These symptoms are more common in the late stages of PD. Your health care team can help you manage these problems with medicine and by suggesting changes in your lifestyle.
Some people with PD develop depression or emotional changes, such as anxiety and sadness. Your health care team can prescribe medicine to treat these symptoms. You can also talk to a counselor for support.
Research on PD is ongoing, and many new medicines are being tested. The National Institutes of Health (NIH) and private foundations fund most of this work. The goal of NIH-funded research is to find more ways to prevent and treat PD. This research includes looking for genetic markers, finding better ways to diagnose PD and developing new therapies to slow the progression of PD.

People with PD often find that their voice becomes quieter, and that it is harder to speak clearly. They may slur their speech, or have trouble with rhythm and pitch. They may also have difficulty with facial expressions and body language. Swallowing problems (dysphagia) are also common in PD and may progress as the disease gets worse. This can lead to drooling, choking or coughing during eating, and can lead to weight loss and dehydration.
The cause of these changes is due to the loss of neurons (or nerve cells) in a part of the brain called the substantia nigra, which produces dopamine. Dopamine is a chemical messenger that allows for smooth, purposeful movement. When these neurons are lost, it can lead to movement and speech difficulties in PD.
Early intervention with a qualified speech-language pathologist is important. In addition to providing advice, she can teach you techniques and assistive devices to help improve your ability to communicate. She can also help you with strategies to minimize the impact of these changes on your daily life.
A speech-language pathologist who is trained in Lee Silverman Voice Treatment can provide a specialized program to help you regain your voice. This involves several sessions over the course of a month together with home practice. During the course of treatment, patients are taught to recognise their own voice volume and work to produce a louder, high-quality voice. They are also encouraged to conserve their energy by using nonverbal communication as much as possible.
Many PD patients with speech problems find that they become withdrawn from friends as their condition deteriorates. But Simon-Kuhn encourages patients to continue to try and keep up as much communication as they can, and to seek professional support for any difficulties that they experience.

Everyone feels dizzy sometimes when they stand up, but if it happens often and is not caused by a cold or medicine you are taking it could be a sign of Parkinson’s.
Other warning signs include autonomic symptoms such as lightheadedness when you stand up (orthostatic hypotension) and constipation. Also, loss of sense of smell (anosmia), sleep problems and feelings of mental or emotional fatigue.
Oren Zarif
The main movement problems of Parkinson’s are due to damage and loss of dopamine-producing nerve cells in the part of the brain called the basal ganglia. This results in symptoms such as slowed movements, tremor and shuffling walk.
Other movement-related problems include ‘freezing’, which occurs when you can’t move or don’t know how to begin moving. This can be frustrating and can lead to serious injury. Physiotherapy and occupational therapy can help you learn strategies to prevent freezing episodes.
Parkinson’s can also cause stiff muscles, making it harder to turn over at night or tie your shoe laces. You may also find that your handwriting becomes small and cramped, and you have trouble blinking. These ‘non-motor’ signs often appear years or decades before motor symptoms.
Other non-motor symptoms can include constipation, orthostatic hypotension (lightheadedness when you stand up), sleep disorders and loss of sense of smell. It’s important to talk to your GP and health professional if you experience these symptoms. They can adjust your medications or refer you to a physiotherapist or occupational therapist for specialist exercise and advice.

Tremors, or shaking, can happen in all parts of the body. But they’re most often seen in the hands and legs. These tremors may be more noticeable when the person is at rest or not using their arms or hands. They usually don’t go away when the affected body part is used. These tremors are a sign of Parkinson’s disease. They can also be accompanied by rigidity, a feeling of tightness or stiffness that affects the limbs and torso. It’s not clear what causes these tremors, but they are different from the tremors caused by some medicines (such as anti-seizure and asthma medications), by drinking too much coffee or alcohol, or by stress or strong emotions.
People over 65 have a higher risk of developing essential tremor than younger people. It isn’t clear what causes it, but it appears to be linked to genes and changes in certain areas of the brain that control movement. It doesn’t cause other symptoms of Parkinson’s disease, such as a numbness and loss of balance.

People with Parkinson’s often have trouble speaking because of a loss of dopamine that leads to speech problems. They may speak softly and in a monotone, which can cause them to be misunderstood. They may have a difficult time swallowing, which can lead to serious complications like drooling or aspiration pneumonia. Swallowing difficulties (dysphagia) can happen at any stage of the disease, change as the disease progresses and get worse over time.
Fatigue that doesn’t go away with rest can also make it hard to talk or think clearly for long periods of time. It’s important to try to avoid long conversations with a person with Parkinson’s and to schedule visits at their best times of the day.
A qualified and experienced speech-language pathologist can provide exercises, drills and strategies to improve voice volume, increase word retrieval, improve facial expressions and emotions in conversation, and improve cognition. They can also help with other symptoms, including writing, drooling and a lack of motivation. Talk to your health care team about getting a referral to a speech-language pathologist.

Swallowing problems are common with Parkinson’s and can affect the quality of your life. It’s important to talk to your neurologist and get advice as early on as possible about how this is affecting you.
Swallow difficulties can lead to drooling and increase your risk of aspiration pneumonia, which is the leading cause of death in people with PD. It’s important to talk to your doctor about this early, and they may refer you to a speech pathologist for an assessment.
Swallowing problems can be made worse by certain medications, so it’s very important to take them at the right time and not miss any doses. If you have a lot of saliva, your doctor might recommend eating more fluids or trying different foods. They may also suggest a soft or liquid diet or chewing gum or sucking sweets to stimulate swallowing. They might also prescribe drugs that can control your saliva, such as a medication called Botulinum toxin (Botox) which is injected into the salivary glands and interrupts nerve messages that cause them to produce it.

People with PD have problems with balance and walking due to the brain changes that take place with PD. These changes affect the part of the brain called the basal ganglia, which is important for balance. To compensate, the brain assigns another area that is used for thinking to control balance instead. This makes it harder to coordinate movements and make decisions about when to move or change direction.
As the disease progresses, it becomes more difficult to walk and to use your arms for balance. You may also develop a tendency to lean forward while you are walking, to drag your feet or shuffle them, or to reduce the swinging of your arms. These changes are called parkinsonian gait.
People with PD sometimes experience mental (cognitive) fatigue, which is a feeling that you can’t think or concentrate for long periods of time. This is because of the chemical changes in your brain. Fatigue is a common problem in PD, and it can be helped by exercise and taking medicines that increase or replace the chemical dopamine.

Parkinson’s disease is associated with a decrease in the number of cells that produce dopamine. This can affect the way you move and cause other symptoms like slow movements, tremors or stiffness.
As Parkinson’s disease progresses you may find you are having difficulty moving your bowels. The reason this happens is because the muscles that control the movement of the bowel and bladder weaken. The loss of dopamine can also affect the way food moves through your bowels, so you may experience constipation and diarrhoea.
You might also experience a feeling that your bowels aren’t empty when you are, this is called false sensations or hallucinations. These can occur as Parkinson’s disease advances and are caused by changes in your brain that affect the way you process information.
A doctor can diagnose Parkinson’s by looking at your medical history and carrying out a physical exam. They might also ask you to complete a questionnaire and may order blood tests or scans. If you have a family history of Parkinson’s disease, they might recommend that you undergo genetic testing for the condition. These tests look for misfolded alpha-synuclein proteins in cerebrospinal fluid, which surrounds the brain and spinal cord, or in skin biopsies from a spot on your back and two spots on your leg.

Symptoms of Parkinson’s disease affect many parts of your body. These include autonomic symptoms such as orthostatic hypotension (low blood pressure when standing up) and constipation. Other symptoms may include a loss of smell, problems identifying odors and fatigue. You might also notice changes in your voice. It may become softer, slower or lose its usual variation in volume and emotion. You might slur your words or have trouble making consonants. You might also experience a lack of expression in your face or speak with a monotone.
A reduced sense of smell and taste, called hyposmia or anosmia, is a common early sign of Parkinson’s. It’s often a symptom that starts years before the other motor symptoms of PD develop. It’s thought that the loss of smell is caused by damage to the cells that produce dopamine in a part of the brain called the substantia nigra.

Your care team may order blood tests or imaging tests, such as MRI, ultrasound of the brain and PET scans, to help rule out other conditions that can cause tremors. Your care team may also give you carbidopa-levodopa (Rytary, Sinemet, others), a Parkinson’s disease medicine. Taking this drug helps reduce your motor symptoms, and significant improvement with this medication confirms the diagnosis of Parkinson’s disease.
PD is caused when neurons in a part of the brain called the substantia nigra stop producing dopamine, a chemical that coordinates movement. Over time, these neurons degenerate and die, leading to the movement-related (“motor”) symptoms of PD. But PD can also lead to non-movement-related (“non-motor”) symptoms, such as depression and anxiety, constipation and problems with the bladder, a reduced sense of smell (hyposmia or anosmia) and sleep disorders.
Fatigue is a common problem for people with Parkinson’s. It can affect up to half of people with the condition. It’s a feeling of tiredness that doesn’t go away with rest. It can be made worse by stress, depression or other factors.

A lack of dopamine disrupts the coordination between nerve and muscle cells. This leads to movement problems, such as tremors.
Your neurologist will probably recommend medication to control your symptoms. But it may take time to find the right medicine and dosage for you.
Clues to Parkinson’s often show up before physical symptoms do, such as loss of smell, a sleep disorder called REM behavior disorder and depression.

Tremor, or shaking, is the first symptom of Parkinson’s that many people notice. It often happens in one arm or hand, and then moves to the other side of the body over time. It may also affect the chin, face or legs. It can be mild and go away on its own, or it can get worse. It can become more noticeable during times of stress or excitement. It is not a sign of dementia, but it can make it difficult to write or speak clearly. Some medications can help reduce the tremor.
In addition to tremor, PD patients experience non-motor (non-movement) symptoms like fatigue and depression. Some of these symptoms appear years or even decades before motor tremors do, and can be hard to connect with the tremors. Other signs include a feeling of urgency to urinate, difficulty sleeping due to REM sleep behavior disorder and loss of sense of smell (anosmia).
Resting tremors are common in Parkinson’s. These tremors occur while your muscles are at rest, such as when you’re sitting or standing still (hence the name). They tend to be less severe than tremor that happens during movement. You may also experience pill rolling tremors, which resemble the circular motion of rolling a pill in your fingers. You may also have a tremor that only occurs when holding a particular body part against gravity, called orthostatic tremor.
People with tremors who don’t have Parkinson’s should see their doctor. They can find out the cause and treat it if needed. It’s important to rule out other conditions that could be causing the tremor, such as essential tremor. The tremor in these cases gets better when your muscle is not moving and it can be reduced with medication, lifestyle changes and meditation techniques.

Stiffness is the main problem in Parkinson’s and usually affects the shoulder, arms and legs. It’s caused when nerve cells in the basal ganglia, an area of the brain that controls movement, become impaired or die. This results in less dopamine being produced.
This leads to a decrease in mobility, which can result in problems such as difficulty walking and wearing clothes. It can also cause problems like facial masking, which is when the muscles of the face become rigid and look like a mask.
Other symptoms of Parkinson’s include constipation, which is often caused by medicines used to treat the disease. People may also experience changes to their sense of smell and fatigue. Constipation can sometimes be a symptom of Parkinson’s before tremors start to develop.
Another symptom is unsteady posture, which can affect both standing and sitting. This can lead to falls and pain in the feet and legs. Some people with PD can develop a dragging, scuffled gait (called’shuffling’), which can make it difficult to get their feet under them when they walk. They can also freeze when they’re moving, which is a common symptom of Parkinson’s and can increase the risk of falling.
There are ways to manage stiffness and improve the way you move, including exercise, which can help stretch and loosen the muscles. It’s important to speak to your GP, specialist or Parkinson’s nurse about this because they can advise you on what exercises are best for you. You can also take medication that can help to relieve stiffness, such as levodopa or a combination of other drugs. Regularly stretching your muscles is also helpful and can be done in many ways, such as in the shower or when you’re sitting down watching TV or reading.

Difficulty walking is a common symptom of Parkinson’s disease. This can be caused by changes to the muscles in your legs, ankles, knees, hips or spinal cord and even to the brain and inner ear. This can make it harder to control your body movement and increases your risk of falling.
Difficilety walking can be due to the loss of dopamine-producing cells in a part of your brain. As a result, your muscles become stiff and you can’t move as easily or quickly. You may also have a shuffle-like gait, a soft or slurred speech and a stooped posture. This can make it hard to walk or get up from a chair and affects your balance and puts you at risk of falls.
Freezing is a sudden short episode of being unable to move your feet forward despite trying to do so. This is sometimes called festination. This can cause you to crash into obstacles in your path or into furniture. People with PD who experience freezing often describe that it happens when they are trying to turn a corner or enter a doorway.
Often the problem with freezing is due to the ‘on/off’ cycle of your Parkinson’s medications. Discussing your medication with your GP and specialist is important to manage this issue. It is also advisable to seek the help of a physiotherapist who can provide you with a personalised assessment and treatment program.
Often when people say they feel weak all over, they are describing the non-motor symptoms of PD such as fatigue and a general sense of unsteadiness. However, some of the motor or gait symptoms of PD could be responsible for this feeling of weakness including bradykinesia, gait disorder and freezing.

Difficulty talking is a common symptom of Parkinson’s disease. Many people with PD start out with slurred speech, which may become more pronounced as the condition progresses. They may also have difficulty pronouncing words and articulation. This can cause their friends and family to misinterpret them as a lack of interest in conversation, aloofness or even depression.
Difficulties with swallowing (dysphagia) can also occur with PD. Swallowing problems are a serious complication because they can lead to weight loss, choking and food entering the lungs. People with PD should let their healthcare providers and/or a speech-language pathologist know as soon as they notice swallowing difficulties.
A plethora of options are available to help people with speech and swallowing difficulties. Your healthcare provider will be able to recommend assistive devices and a speech-language pathologist for further evaluation.
Slurred speech and swallowing difficulties are difficult for everyone involved. But they can be especially frustrating for people with a cognitive condition like Parkinson’s. They often feel isolated and frustrated, which can lead to stress and depression. They are often forced to use nonverbal communication, such as hand signals and facial expressions to communicate with others.
In addition to recommending assistive devices, a speech-language pathologist can teach you strategies that can help you conserve energy and improve your ability to speak clearly. They can also show you how to use the device that best fits your needs. They can also teach you ways to use your voice more efficiently, such as using a whispered or soft tone. MJFF is working toward better therapies to address these challenges. You can join a clinical study to learn more about the latest advancements by visiting Fox Trial Finder.

Depression is a serious mental health condition that affects your mood and emotions. It can cause feelings of sadness, hopelessness and worthlessness that interfere with your daily functioning. Depression can also make it hard to think clearly and feel energized. People with PD often experience depression because of the way Parkinson’s disease changes their brains. PD damages nerve cells in the basal ganglia, causing them to stop producing dopamine, a chemical that carries messages between nerve cells. Without enough dopamine, the brain can’t control movement-related symptoms like shaking and stiffness. The loss of dopamine in the brain also causes non-motor symptoms such as depression, hallucinations and sleep problems.
You may be able to manage your symptoms through lifestyle changes, medicine and therapy. Talk to your doctor if you’re worried about depression. He or she can screen you for depression and prescribe antidepressant medicines if needed. You can also get support from friends and family, join a Parkinson’s support group or take part in online discussion forums.
People with PD are more likely to have depression than those who do not have the disorder. Symptoms of depression can be hard to distinguish from the typical tremors associated with PD, so it is important to tell your doctor about them. Your doctor will also want to ensure that you are taking your PD and depression medications properly so that they do not interact with each other. The National Institutes of Health recommends that you eat well, exercise and get enough sleep. You should also avoid alcohol and recreational drugs because they can make depression worse. If you’re interested in trying psychological therapy, look for an approach that focuses on changing patterns of thought and behavior to ease depression and anxiety.
