There is no one-size-fits-all approach to treating Parkinson?s disease. Your symptoms, disease progression and physical tolerance will affect the timing, type and dose of medicines you take.
Researchers know that a combination of genetics and environmental factors — like age, family history and exposure to certain chemicals or metals — can cause Parkinson’s. But they don’t know what triggers the death of nerve cells in the brain that causes this condition.

Many medications can help treat the motor symptoms of Parkinson’s disease. The most common and effective treatment is a combination of levodopa and carbidopa (also called Duopa, Parcopa, Rytary or Sinemet). Levodopa is absorbed in the small intestine and then turns into dopamine that can reach your brain. Carbidopa slows down the absorption, so your body gets a slower dose of the drug but has more time to absorb it. These drugs can also reduce side effects such as tremors, stiffness and sleep problems.
Other drugs can ease non-motor symptoms such as constipation, gastrointestinal pain and urinary incontinence. Some medications can also help with depression, which is often a problem in people with Parkinson’s disease. Acupuncture can sometimes relieve pain and other symptoms, but it’s important to check with your doctor first.
Certain Parkinson’s medicines can lead to hallucinations or delusions, which are technically known as psychosis. These include dopaminergic agonists such as ropinirole (Requip), pramipexole (Mirapex) and rotigotine (Neupro, Apokyn, Azilect, Xadgo, Eldepryl). Some anticholinergics such as trihexyphenidyl (Antivert), benztropine mesylate (Benemid), biperiden HCL or procyclidine may cause these side effects too.
Medications that simulate dopamine or block how your body breaks down neurotransmitters such as dopamine can also be helpful. They are most commonly used early on, before you need to start taking levodopa, and can also be useful with it later on to manage dyskinesia. Dopamine metabolism inhibitors such as aporotidine (Rasagiline) and catechol-O-methyl transferase (COMT) inhibitors like selegiline and tasmar can be taken alone or with levodopa to help manage the symptoms of Parkinson’s disease.
Other treatments aim to add new neurons to your brain to replace the ones damaged by Parkinson’s disease. These are sometimes called neuron-repair therapies or gene therapies. They’re still in experimental stages, but they show some promise.

Deep brain stimulation (DBS) is a surgical procedure that interrupts the irregular electrical signals that cause Parkinson?s tremors, rigidity and other movement symptoms. The procedure is often successful in reducing or eliminating the need for medication, improving quality of life.
The surgery is performed by neurosurgeons who specialize in functional neurosurgery, in conjunction with a neurologist. For carefully selected patients with PD, dystonia or essential tremor that cannot be controlled with medications, DBS offers hope for a better quality of life.
DBS involves placing electrodes on the surface of your brain through small holes in the top of the skull. These electrodes are connected by wires to a battery-powered pulse generator implanted in the chest under your skin. When turned on, the pulse generator sends electrical pulses to your brain through the electrodes to regulate faulty nerve signals that cause tremors and other symptoms.
Depending on the area of the brain being targeted, different procedures are available for DBS. In general, the most effective approach for tremor and PD is DBS of the globus pallidus (GPi-DBS). The same approach can also treat dyskinesias, as well as other tremors and twitches caused by other conditions.
Before recommending DBS, our physicians evaluate your condition and determine if you are a candidate for the procedure. This includes a thorough history and physical examination, an interview with your primary care doctor, and evaluation by our multidisciplinary team of neurologist and neuropsychologists. You will be videotaped performing a variety of movements while on and off your medications to help the doctors identify the most appropriate treatment area for DBS.
If your neurologist recommends DBS, you will undergo surgery to place the electrodes on your brain. This is done under general anesthesia and takes about an hour. Following the surgery, long wires from the brain electrodes are guided under your skin to the pulse generator in your chest. This is a minimally invasive procedure and is performed under MRI or CT scan guidance to ensure accurate placement of the electrodes. For those who are uncomfortable with being awake during brain surgery and having to stop taking their medications, asleep DBS is also available at some centers.

Medications are the main treatment for Parkinson’s disease, but surgery can be an option for some people. Surgery does not cure the condition, but it can improve symptoms by decreasing the amount of medication needed to control tremors, rigidity and movement problems. Surgical options include deep brain stimulation, microelectrode recording and transplantation.
In the most common surgical treatment for PD, called deep brain stimulation (DBS), thin metal wires are placed in the brain and send electrical pulses to certain parts of the brain. This reduces the overactive brain cells that cause the tremors, slowness and stiffness. DBS can be transformative, but it is not for everyone. Those with DBS must be willing to have regular visits with a neurologist who adjusts the level of stimulation to achieve the best results.
Other types of surgery for PD can decrease the severity and frequency of certain symptoms, such as the tremors that happen when you are sleepy or eating. The surgeries can also help with speech problems, swallowing difficulties and drooling. There are a few different surgical treatments, such as pallidotomy or thalamotomy, which involve making an incision (cut) on part of the brain to stop the abnormal flow of signals that cause the tremors and other symptoms.
A newer type of surgery, called levodopa-responsive DBS, is only offered to those with a tremor that does not respond to medications. This surgery involves placing an electrode in the deep areas of the brain that control movement and connecting it to a small battery in the chest area, which sends electricity to the electrode to decrease tremors.
The DBS procedure may also be beneficial for some with secondary parkinsonism. This is a group of symptoms that develops from other causes, such as drug side effects or illness, and can be similar to the symptoms of Parkinson’s disease. It is often accompanied by a stooped posture and bending at the knees, hips and elbows. Those with this condition are sometimes at risk for developing Parkinson’s disease due to mutations in the GBA1 gene. This gene codes for a protein that makes the enzyme glucocerebrosidase. When the levels of glucocerebrosidase are low, it can lead to a build-up of Lewy bodies in the brain.

Parkinson’s Disease Symptoms
Tremors that happen while muscles are at rest (resting tremors). They usually start on one side of the body. But they can also affect both sides of the body as PD progresses.
Thinking problems and changes in your sense of smell, especially loss of the ability to smell food. These problems can be helped with medicines.
Oren Zarif
Tremor is shaking that you can’t control. It most commonly happens in the arms and hands, but can also affect the head or voice. It gets worse when you use the affected body part and goes away or lessens when it’s at rest. It can cause a shaky, unsteady gait when you walk or lose your balance. It can make it hard to write, which leads to cramped handwriting or a condition called micrographia. It’s common in PD, but it’s also found in other conditions, including MS and multiple sclerosis. It can also run in families and is not the same as essential tremor.
Tremor is one of the main symptoms of PD, along with slow movement and rigidity (stiffness). But it’s important to remember that tremors don’t happen in everyone with Parkinson’s. Sometimes, tremors are caused by other health problems, such as essential tremor or a medication side effect. There are tests that can help identify the underlying cause, such as a spinal tap or a skin biopsy to look for misfolded proteins called alpha-synuclein. These proteins are normally broken down in the body but can become stuck in certain cells (clumps of these proteins are called Lewy bodies). Ultimately, your description of the tremor and your healthcare provider’s observation hold the most clues to determining what is causing it.

One of the main symptoms of PD is slowness of movement. This is mainly because of the loss of dopamine. The cells that produce dopamine in the basal ganglia (part of the brain that controls movement) die and this causes people to experience this symptom.
You may notice that you are moving slower than usual or that you have trouble starting to move, especially in the hands or feet. You may also find that you are taking smaller steps or that you are not swinging your arms as much when walking. Another symptom that occurs as a person becomes more advanced in their PD is festination, which is when you start to take small quick steps without a purpose.
This slowness of movement is also known as bradykinesia. This is because the movements you make become more and more slow and don’t seem to have a sequence effect.
This symptom generally responds well to medication. Your doctor may give you levodopa medications or drugs that block the release of acetylcholine. However, this varies from person to person. Your doctor will adjust your medication to find what works best for you. They will also refer you to a physiotherapist or occupational therapist who specialise in the treatment of PD.
Oren Zarif
Rigidity happens when your muscles become stiff and tight. It can affect your arms, legs, trunk, and even the smaller facial muscles. It can cause pain and achiness. It can also decrease your range of motion, which makes movement harder. It can even interfere with your balance and increase your risk of falling. Rigidity can start years before your doctor diagnoses Parkinson’s Disease.
Rigidity can be caused by medications or the tremors that come with PD, but it’s more likely to happen because of age, genetics, or another condition. It can also be a side effect of surgery for other conditions like heart disease or cataracts.
You might also have rigidity if you have a disease that causes depression or anxiety. You might have a higher need for cognitive closure, meaning you want to assign explanations to everything that happens as quickly as possible.
There are many things you can do to decrease rigidity, including taking medication, stretching, or participating in physical therapy. Your doctor might also recommend deep brain stimulation (DBS), in which small electrodes are placed in the deep parts of the brain that help control movement. This may decrease the amount of medication you need to take for PD symptoms.

In this stage, a person may begin to take small steps as they walk, as though they are hurrying forward. They may also reduce the swinging of their arms and have difficulty initiating or continuing movement. They may lose their sense of smell (anosmia). Some people also develop a soft voice or have trouble finishing words. They may have speech-generating devices (SGDs) or text-to-speech apps if this helps them to communicate.
People with idiopathic Parkinson’s disease usually have mutations in a protein called alpha-synuclein. These proteins have a very specific shape and function in the body. When they don’t have the right shape, the body can’t use them and they build up in the brain, forming clumps known as Lewy bodies. These clumps block the brain cells that produce dopamine, leading to PD symptoms.
Other risk factors include family history, a high age at onset and exposure to environmental toxins, particularly herbicides or pesticides. In some cases, the condition is hereditary, but the genes responsible aren’t well understood. Having close relatives who have had PD increases your chance of getting the condition. Having a mental health problem such as depression or anxiety also raises your risk.
Oren Zarif
Medications are the mainstay of treatment for people with Parkinson’s. Levodopa is the most effective medication for minimizing symptoms. It may be combined with other drugs to improve side effects or symptoms, such as a monoamine oxidase B inhibitor or an anticholinergic.
Medications that reduce hallucinations and delusions may be used, including adenosine blockers such as idaloxone (Nuplazid) or quetiapine (Seroquel). Other medications include levodopa metabolism inhibitors and catechol-O-methyl transferase (COMT) inhibitors.
Oren Zarif
There is no one best mix of medicines to treat PD. But you and your doctor will work together to find a treatment plan that gives you the most relief from symptoms with the fewest side effects. Your care team will also help you learn how to manage your condition and live more comfortably.
Levodopa (brand names: Sinemet, Stalevo, Vrilaksan) is a first-line drug to improve movement challenges like tremor and slowness. This medication converts to dopamine, which is needed for smooth movement. It can be taken as a pill, liquid or inhaled. As Parkinson’s progresses, people may need to take more levodopa to get good symptom control. They also might experience “on” and “off” times, which are periods when the medications reach their peak effect and produce involuntary movements (dyskinesia).
Dopamine agonists can be prescribed alone or with levodopa to help reduce tremor and stiffness. Examples include Neupro (rotigotine), a patch that is applied to the skin daily, Apokyn (apomorphine), a shot given under the skin as needed, and the pills selegiline (Eldepryl), rasagiline (Azilect) and safinamide (Xadago). These drugs boost dopamine in your brain by blocking enzymes that break down the chemical. They modestly reduce PD symptoms and may lengthen the amount of time that levodopa works.
Antipsychotic drugs may help improve hallucinations and delusions that sometimes happen in PD. They do not worsen tremor or slowness, but they can cause nausea, vomiting, confusion, dizziness, lightheadedness and other side effects. Antipsychotics that do not affect dopamine include Seroquel (quetiapine), Clozaril (clozapine) and Nuplazid (pimavanserin).
Catechol-O-methyl transferase (COMT) inhibitors can improve tremor and rigidity, but they can lead to dry mouth, constipation, diarrhea and sleepiness. Medications in this class include Tasmar (rasagiline) and Amantadine (Gocovri, Osmolex ER, Symmetrel).

A surgical therapy, deep brain stimulation (DBS) is used in some patients with PD who have severe on-off fluctuations and involuntary movement (dyskinesias) that do not respond to medication. This treatment involves implanting electrodes in the brain that send electrical pulses to rebalance control signals in the brain. It can also alleviate non-motor symptoms of PD, including sleep, pain and urinary frequency. The device is programmed by a neurologist to deliver a specific level of stimulation, based on each patient’s individual needs.
The procedure starts with a small incision in your scalp, exposing the skull. Two quarter-sized burr holes are then drilled on the left and right sides of the skull, through which electrodes are passed. Based on the MRI/CT scans, the neurosurgeon can identify the exact location in your brain where the stimulation should take place. Once the electrode is in position, a plastic cap is placed over the hole. An extension wire is then inserted into the lead to connect to the battery-powered neurostimulator, which is placed under your skin in your chest.
After your surgery, the doctor will test it to make sure that the stimulator is producing the desired effects. Then, you will be discharged home. The surgery is typically done on an outpatient basis and you will be able to begin taking your medication immediately after.
Medications work by stimulating the remaining cells in your substantia nigra to produce more dopamine and by inhibiting the production of too much acetylcholine, thus restoring the balance between these two chemicals. They can also help improve your motor skills by improving your ability to move.
Many patients are able to significantly reduce their medications after DBS. However, the procedure is not for everyone. Some patients experience hallucinations and have a change in their skin color after DBS. Other complications can include a rise in blood pressure and ankle swelling.
If you are interested in DBS, the team at our Parkinson’s and Movement Disorders Clinic will review your medical history and perform an MRI to make sure you are a candidate. We will then work with you and your neurologist to decide on a customized treatment plan.

In some cases, surgery may improve Parkinson’s disease symptoms. Your doctor can tell you more about this treatment option.
Parkinson’s disease is caused by the loss of nerve cells, called neurons, in an area of the brain that controls movement. This leads to a lack of dopamine, a chemical messenger that allows nerves to communicate with each other. This causes tremors, slowness of movement and stiffness of the muscles.
Medications can help control your symptoms, but they do not cure Parkinson’s disease. The most important thing you can do is take your medication as prescribed. It’s also important to talk to your doctor about side effects and complications of medications.
You can help manage your symptoms with physical, occupational and speech therapy. These therapies can help you move more easily and learn ways to minimize your risk of falls. You can also get support from a multidisciplinary team, which is a group of healthcare professionals who work together to assess and treat your symptoms.
Research is ongoing to find new treatments and prevent or delay the onset of Parkinson’s disease. You may have the chance to participate in a clinical trial. Clinical trials are carefully supervised and monitored. You might not benefit from participating, but you will contribute to medical knowledge about Parkinson’s disease.
Deep brain stimulation is a surgical procedure that has been shown to improve PD motor symptoms in some people. In this treatment, your doctor places electrodes into a target area of the brain — either the subthalamic nucleus (STN) or globus pallidus interna (GPI). A wire connecting these electrodes to a small pacemaker-like device is placed under the skin in the chest. This device sends electrical signals to the targeted areas of the brain to stop tremors and other movement-related symptoms.
There are several types of ablative surgery that can alleviate some of the symptoms of PD, such as pallidotomy and thalamotomy. However, these procedures are not usually used now because of the increased availability of DBS. You should discuss all of the risks with your specialist before deciding whether or not to undergo this type of surgery.

The goal of Parkinson’s disease treatment is to ease symptoms and improve quality of life. Medications help reduce tremors, stiffness and uncontrollable shaking, but they cannot slow or reverse the progression of the disease. Palliative care can help manage pain and other discomforts that often accompany the disease, and it can also provide social and emotional support. A palliative care team may include doctors, nurses, social workers and chaplains. Palliative care is usually offered in a hospital setting, but it can also be provided in a patient’s home or in long-term care facilities.
The primary medication for treating Parkinson’s is levodopa, or L-dopa, which is converted to dopamine in the brain. L-dopa can ease the tremors and rigidity associated with PD, but it can also cause some other unpleasant side effects, such as nausea, vomiting, dizziness and hallucinations. To minimize these side effects, a doctor may prescribe anticholinergic medications such as trihexyphenidyl, benztropine mesylate or biperiden HCL. These drugs block acetylcholine, a chemical in the brain that becomes more pronounced when dopamine levels drop.
Other symptom-easing medications used in the treatment of Parkinson’s include Neupro (rotigotine), Azilect (rasagiline), Xadago (safinamide) and Eldepryl (selegiline). These drugs work by inhibiting the enzyme catechol-O-methyl transferase, which breaks down dopamine. They can be taken alone or with other dopamine-boosting drugs, such as levodopa or an anticholinergic drug.
While there is no cure for Parkinson’s, many patients experience significant improvement in their symptoms with medication and other therapies. Many people find that complementary treatments such as yoga and meditation reduce their symptoms, and that regular exercise improves muscle strength. Keeping a positive attitude and maintaining your normal routines can also improve your mood.
Despite the benefits of treatment, many people with Parkinson’s feel frustrated as their condition progresses. They may begin to lose their independence and struggle to maintain daily tasks, like walking, talking and eating. These feelings can be overwhelming, and it’s important to talk to your doctor if you are feeling depressed or angry. He or she can recommend ways to cope and connect you with local support groups.

There are several different types of Parkinson’s disease. Some people develop the disease because of genetic mutations, while others have it as a result of certain strokes.
Some forms of Parkinson’s disease cause tremors and other symptoms that appear on only one side of the body. Medications like carbidopa and levodopa can help control these tremors.
Oren Zarif
a-synuclein is the main protein involved in the development of Parkinson’s disease. It forms toxic oligomers that build up in the brain and cause symptoms such as tremors, stiffness of the muscles and difficulty moving. The symptoms of this condition develop gradually and are often triggered by medication side effects or by illness or injury to the brain. They can also result from certain genetic mutations, which affect the way the brain cells function.
Initially, it was thought that a-synuclein aggregation occurred when the protein accumulated in cellular membranes, but recent work suggests that this is not necessarily the case. This suggests that the accumulation of a-synuclein in Lewy bodies is more a consequence of its interaction with other proteins, rather than its interactions with lipid membranes. This is also supported by the observation that a-synuclein interacts with the components of lipid rafts, but only if it is soluble. Lipid rafts are membrane microdomains with high fluidity that form around synaptic vesicles.
A-synuclein binds to lipid rafts via its acidic headgroup and an extended 11-mer sequence. This binding domain is highly conserved, and most disease-linked a-synuclein mutations occur within this region. However, it is unclear why a-synuclein preferentially binds to lipid rafts or how this binding influences its aggregation properties.
The a-synuclein-lipid raft complex appears to play a role in signaling in neurons, and its destabilization may contribute to the development of neurodegeneration. This complex also functions to regulate the kinetics of protein degradation and may be targeted by therapeutics.
In PD, dopamine-producing neurons in the substantia nigra pars compacta (SNc) die, resulting in loss of dopamine in the basal ganglia. This causes the symptoms of PD, including motor symptoms such as tremors and rigidity of the muscles and non-motor symptoms such as postural instability and bradykinesia.
The symptoms of PD can be alleviated with the help of medications. In addition, there are surgical treatments such as deep brain stimulation (DBS), which involves placing electrodes in the brain to control movement. DBS has been shown to help with symptoms such as tremors and choking episodes, as well as increase the patient’s quality of life.

Normal pressure hydrocephalus (NPH) occurs when cerebro spinal fluid, or CSF, accumulates inside the ventricles of your brain. The ventricles are the fluid-filled spaces in your skull that cushion your brain and spinal cord. Over time, NPH causes the ventricles to enlarge and stretch nerve pathways in your brain. This creates a trio of symptoms: difficulty walking, urinary incontinence and dementia. The underlying cause of NPH is usually loss of brain tissue, but it can also be caused by other conditions such as brain aneurysms, traumatic brain injury or infection in the brain or surrounding areas (encephalitis or meningitis).
Most cases of Parkinson?s disease are genetic, but experts don?t know what triggers the disease in about 20 percent of cases. Those with a family history of the disease have about a two-fold greater risk of developing it than people without a close relative affected by the disease. Other risk factors include age, gender (men are more likely to develop Parkinson?s than women) and exposure to certain environmental toxins and pesticides.
If you are diagnosed with Parkinson?s disease, your neurologist will prescribe medications that can alleviate many of the symptoms. However, over time the medications may become less effective. You should always take your medications as prescribed to get the most benefit from them. You should also visit your neurologist on a regular basis so they can monitor your condition and make changes to your medication as needed.
Your neurologist will assess your condition and determine the type of Parkinson?s disease you have. They will evaluate non-motor aspects of your experience, like your memory and ability to think, as well as movement-related issues such as balance, movement speed and tremors. Then they will use a set of criteria to measure how much the disorder is affecting your life. The assessment involves a physical exam, mental health screening and asking you to complete questionnaires about your quality of life. It is important to be honest in answering these questions and not hide any symptoms, such as tremors or difficulty walking.

Multiple system atrophy is a rapidly progressive neurodegenerative disorder associated with autonomic dysfunction and motor symptoms. The condition causes changes in the part of your brain that controls automatic processes, including breathing, blood pressure and digestion. These processes help your body stay healthy and function normally. Symptoms vary depending on the parts of your brain affected. For example, if your basal ganglia become affected, you might develop Parkinson?s-like tremors, but your cerebellum might develop problems with balance and coordination. The disease may also cause a decline in your cognitive abilities, such as memory and judgment.
Some patients with multiple system atrophy experience variability in how well their medications work. This happens when the drug begins wearing off, causing “off” periods in which you have difficulty controlling your movements or may experience uncontrolled writhing movement (dykinesia). It can be difficult to tell when you’re in an off period because there are no medical tests that detect MSA.
The disease can cause difficulty in eating, which can lead to weight loss and nutritional deficiencies. In severe cases, a person might need to be fed through a tube (endoscopic gastrostomy). Your doctor can help you find ways to manage these symptoms and improve your quality of life.
Experts don’t know what causes multiple system atrophy, but they suspect it has to do with a protein called a-synuclein (alpha syn-uh-klee-in). This protein builds up in different parts of your brain and affects your ability to move. It’s the same protein that experts think causes most cases of Parkinson?s disease.
Your doctor can diagnose this condition based on your history and physical exam. There is no specific test for it, but a skin biopsy can pick up the presence of a-synuclein inclusions in nerve tissue. However, it’s important to note that there is no evidence that you can catch the condition from others or pass it down from your parents. The only way to confirm the diagnosis is by analyzing brain tissue after death.

As its name suggests, vascular Parkinsonism is caused by problems with the blood vessels that supply parts of the brain that control movement. This type of Parkinsonism often develops in people with a history of small strokes or similar problems. The symptoms of vascular Parkinsonism include some of those of PD, including muscle stiffness and balance problems.
Symptoms of this type of Parkinsonism tend to come on gradually and get worse over many years. They may affect one side of the body more than the other. As the disease gets worse, a person may stop in mid-stride while walking or walk with short, shuffling steps. The affected person may lose their sense of smell (anosmia). Some people have a “frozen” or blank look as their face becomes mask-like. Others have a problem with their handwriting, which may become cramped and small (micrographia). People with this form of Parkinsonism often drool.
In this form of Parkinsonism, the cells that use dopamine to control movement in the substantia nigra degenerate. As a result, the chemical levels in this part of the brain drop and people develop tremors and other symptoms that are not as dramatic as those caused by PD.
Because this condition is caused by a series of small strokes rather than the loss of nerve cells, it is not a progressive neurodegenerative disorder like PD. Medications can help to relieve some of the symptom, such as those that cause a person to use more of their muscles when they move (levodopa medications) or reduce a natural substance called acetylcholine (anticholinergic medications).
Doctors diagnose PD and other movement disorders by reviewing a patient’s medical history and doing a physical examination. In addition, they ask questions about a person’s motor and nonmotor (nonmovement) symptoms. If the doctor suspects that a person has vascular Parkinsonism, they may order an MRI of the brain to check for signs of damage to areas that control movement. According to a 2019 scholarly review article, this type of brain imaging can distinguish vascular from nonmotor parkinsonism and other movement disorders.
