How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.
Exercise And Parkinsons Disease
Research conducted by the Parkinsons Foundation reveals that exercising at least 2.5 hours per week improves symptoms and slows disease progression. The group also found that the earlier patients began exercising, the more pronounced the benefits were.
To help with balance and mobility, the Foundation recommends aerobics, strength-training, and flexibility exercises. Popular options include:
- Biking
- Weight lifting
- Yoga
The real secret to the best exercise program, though, is doing what you enjoy. For some ideas, please see our previous articles on strength-building exercise and how to begin an exercise program. And remember, never begin a new exercise regimen without talking to your doctor.
What Is The Prognosis And Life Expectancy For Parkinson’s Disease
The severity of Parkinson’s disease symptoms and signs vary greatly from person to peson, and it is not possible to predict how quickly the disease will progress. Parkinson’s disease itself is not a fatal disease, and the average life expectancy is similar to that of people without the disease. Secondary complications, such as pneumonia, falling-related injuries, and choking can lead to death. Many treatment options can reduce some of the symptoms and prolong the quality of life.

How Is Parkinson’s Disease Managed
Your doctors will tailor your treatment based on your individual circumstances. You will manage your condition best if you have the support of a team, which may include a general practitioner, neurologist, physiotherapist, occupational therapist, psychologist, specialist nurse and dietitian.
While there is no cure for Parkinson’s disease, symptoms can be treated with a combination of the following.
Surgical Options For Parkinsons Disease
As of 2019, there are two surgeries prescribed to treat Parkinsons. These are only ordered if medications previously helped control movement symptoms but are no longer effective.
The first is called deep brain stimulation. The surgeon inserts a wire, or lead, into the subthalamic nucleus, which is the part of the brain that controls movement. The wire extends to an external device called a neurostimulator. This sends electrical pulses through the lead to stimulate the subthalamic nucleus.
The second surgery is prescribed in cases where the patient suffers too many side effects from the levodopa or requires too strong a dose. A surgeon inserts a tube in the small intestine, through which the patient receives doses of carbidopa. This enhances the effect of levodopa, allowing the patient to receive a smaller dose.

Medications To Help Treat Parkinsons Disease Psychosis
Your doctor might consider prescribing an antipsychotic drug if reducing your PD medication doesnt help manage this side effect.
Antipsychotic drugs should be used with extreme caution in people with PD. They may cause serious side effects and can even make hallucinations and delusions worse.
Common antipsychotic drugs like olanzapine might improve hallucinations, but they often result in worsening PD motor symptoms.
Clozapine and quetiapine are two other antipsychotic drugs that doctors often prescribe at low doses to treat PD psychosis. However, there are concerns about their safety and effectiveness.
In 2016, the approved the first medication specifically for use in PD psychosis: pimavanserin .
In clinical studies , pimavanserin was shown to decrease the frequency and severity of hallucinations and delusions without worsening the primary motor symptoms of PD.
The medication shouldnt be used in people with dementia-related psychosis due to an increased risk of death.
Psychosis symptoms caused by delirium may improve once the underlying condition is treated.
There are several reasons someone with PD might experience delusions or hallucinations.
Brain Imaging And Other Tools To Aid Diagnosis Of Parkinsons
In addition to taking a history and performing a detailed neurologic examination, physicians sometimes use brain imaging to help support a particular diagnosis. However, these studies have their limitations in the diagnosis of Parkinsons disease and are typically used only in select patients. Brain imaging is not routinely performed by neurologists or movement disorder specialists when they are considering a diagnosis, especially if the persons symptoms strongly suggest to the physician that idiopathic Parkinsons disease is the correct diagnosis.
Helping diagnose Parkinsons with DaTscan and other tests
Rather, use of imaging is most helpful when the diagnosis is uncertain, or when physicians are looking for changes in the brain that are more typical of one of several Parkinsonian syndromes and other conditions that can mimic Parkinsons. Imaging studies to evaluate Parkinsons disease and Parkinsonian syndromes include magnetic resonance imaging , which examines the structure of the brain, and DaTscan, an imaging test approved by the Food and Drug Administration to detect the dopamine function in the brain. A DaTscan may help differentiate idiopathic Parkinsons disease from certain other neurologic disorders. Most physicians offices will have access to MRI however, DaTscan imaging may only be available at larger hospitals or medical centers.

What Medications Are Used To Treat Parkinsons Disease
Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.
Medications combat Parkinsons disease by:
- Helping nerve cells in the brain make dopamine.
- Mimicking the effects of dopamine in the brain.
- Blocking an enzyme that breaks down dopamine in the brain.
- Reducing some specific symptoms of Parkinsons disease.
Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .
Discuss With Your Physician
Non-motor symptoms can sometimes be difficult to recognize. Therefore, it is important to make your doctor aware of them.
One useful resource is the PD NMS Questionnaire. You can use this to record your symptoms and discuss them with your doctor.
Dr. Ron Postuma, whose research was funded by donations to the Parkinson Canada Research Program, has also developed tools to help people with Parkinsons and their physicians identify and manage non-motor symptoms.

Impaired Posture And Balance
As a person with Parkinsons disease loses some of the reflexes and coordination required to maintain an upright posture, they may become stooped or slouched over. This doesnt happen overnight, however. Healthline says that posture will change in small ways at first, and will gradually worsen.
Parkinsons disease may also affect a persons balance, causing them to sway backwards when rising from a chairknown as retropulsion. Retropulsion may also make pivoting, turning or quick movements especially difficult.
What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s. Scientists still do not know what causes cells that produce dopamine to die.
People with Parkinson’s also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinson’s, such as fatigue, irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.
Many brain cells of people with Parkinson’s contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.

What Is It And How Does It Affect Those Whove Been Diagnosed
Parkinsons disease is a type of movement disorder that can affect the ability to perform common, daily activities. It is a chronic and progressive disease, meaning that the symptoms become worse over time. It is characterized by its most common of motor symptomstremors , stiffness or rigidity of the muscles, and slowness of movement but also manifests in non-motor symptoms including sleep problems, constipation, anxiety, depression, and fatigue, among others.
Confusion With Essential Tremor
The tremor of Parkinsons disease is often confused with the tremor of a condition called Essential Tremor, or Benign Familial Tremor . Katherine Hepburn had Essential Tremor, and was originally misdiagnosed with Parkinsons. Ronald Reagan also had Essential Tremor. Both had a head tremor and a vocal tremor. In Essential Tremor, the hands are most commonly involved, followed by the head and then the voice. Essential Tremor can also cause the jaw to tremor, and it may be difficult to figure out if a jaw tremor is from Essential Tremor or Parkinsons. Unfortunately, some people may have both disorders. Some authorities believe that there is, in fact, an increased association between the two conditions, so that more people with Parkinsons disease have Essential Tremor than would be expected by chance alone, but this has not been established.

Memory Problems And Dementia
Research shows that hallucinations and delusions often happen when someone with Parkinsons also has problems with memory, thinking problemsor dementia.
If you experience hallucinations at an early stage of Parkinsons, it could be a sign of another medical condition, such as dementia with Lewy bodies.
Support For People With Parkinsons Disease
Early access to a multidisciplinary support team is important. These teams may include doctors, physiotherapists, occupational therapists, speech therapists, dietitians, social workers and specialist nurses. Members of the team assess the person with Parkinsons disease and identify potential difficulties and possible solutions.There are a limited number of multidisciplinary teams in Victoria that specialise in Parkinsons disease management. But generalist teams are becoming more aware of how to help people with Parkinsons disease.

Most People With Parkinson’s Disease Will Experience Constipation At Some Point
Whether or not you experience constipation early, if you have Parkinson’s, you’ll likely experience this symptom at some point. According to the Canadian Society of Intestinal Research, constipation is one of the most frequently reported gastrointestinal symptoms of the disease, with about 60 to 80 percent of patients with Parkinson’s experiencing this as a result of their health condition.
“In Parkinson’s, constipation can be part of the disease process. PD can affect the autonomic nervous system, a network of nerves that directs bodily functions we don’t consciously control, such as blood pressure and digestion,” the Michael J. Fox Parkinson’s Foundation states on its website. “When digestive tract movement slows in PD, constipation can happen. Recent research also has linked changes in gut bacteria with Parkinson’s disease these disruptions may contribute to constipation.”

Common Symptoms Of Parkinsons Disease
Parkinsons is mostly known for its movement-related symptoms . Everyone with Parkinsons has the first symptom, bradykinesia. The term literally means slowness of movement. Researchers believe that this is due to changes in the motor areas of the brain . These changes interfere with the brains ability to execute the commands to move.
Experiencing bradykinesia alone does not result in a diagnosis of Parkinsons disease. The patient must also exhibit at least one of the following movement symptoms:
- Postural instability
- Rigidity
- Tremor
Of the three, tremor is the most common and most commonly associated with the condition. It presents as a slight shaking in the hand or chin. Rigidity is when the patient experiences stiffness in the arms or legs that is not caused by arthritis. Finally, postural instability simply means that the patient has issues with balance or is prone to falling.
Other movement symptoms include:
- Insomnia, excessive daytime sleepiness, restless legs syndrome, vivid dreams, and other sleep disorders
- Losing sense of taste or smell
- Mood disorders such as anxiety, depression, and apathy
Some non-movement symptoms do not become apparent until a patient has had PD for many years.

What Is The Treatment For Parkinson’s Disease
There is currently no treatment to cure Parkinson’s disease. Several therapies are available to delay the onset of motor symptoms and to ameliorate motor symptoms. All of these therapies are designed to increase the amount of dopamine in the brain either by replacing dopamine, mimicking dopamine, or prolonging the effect of dopamine by inhibiting its breakdown. Studies have shown that early therapy in the non-motor stage can delay the onset of motor symptoms, thereby extending quality of life.
The most effective therapy for Parkinson’s disease is levodopa , which is converted to dopamine in the brain. However, because long-term treatment with levodopa can lead to unpleasant side effects , its use is often delayed until motor impairment is more severe. Levodopa is frequently prescribed together with carbidopa , which prevents levodopa from being broken down before it reaches the brain. Co-treatment with carbidopa allows for a lower levodopa dose, thereby reducing side effects.
In earlier stages of Parkinson’s disease, substances that mimic the action of dopamine , and substances that reduce the breakdown of dopamine inhibitors) can be very efficacious in relieving motor symptoms. Unpleasant side effects of these preparations are quite common, including swelling caused by fluid accumulation in body tissues, drowsiness, constipation, dizziness, hallucinations, and nausea.
Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- medication
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .

Sidebar: Advances In Circuitry Research
The brain contains numerous connections among neurons known as neural circuits.
Research on such connections and networks within the brain have advanced rapidly in the past few years. A wide spectrum of tools and techniques can now map connections between neural circuits. Using animal models, scientists have shown how circuits in the brain can be turned on and off. For example, researchers can see correlations between the firing patterns of neurons in a zebrafishs brain and precise behavioral responses such as seeking and capturing food.
Potential opportunities to influence the brains circuitry are starting to emerge. Optogenetics is an experimental technique that involves the delivery of light-sensitive proteins to specific populations of brain cells. Once in place, these light-sensitive proteins can be inhibited or stimulated by exposure to light delivered via fiber optics. Optogenetics has never been used in people, however the success of the approach in animal models demonstrates a proof of principal: A neural network can be precisely targeted.
Thanks in part to the BRAIN Initiative, research on neural circuitry is gaining momentum. The Brain Research through Advancing Innovative Neurotechnologies Initiative is accelerating the development and application of new technologies that enable researchers to produce dynamic pictures of the brain that show how individual brain cells and complex neural circuits interact at the speed of thought.

Environmental Factors And Exposures
Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never having smoked cigarettes, and never drinking caffeinated beverages, are also associated with small increases in risk of developing PD.
Low concentrations of urate in the blood is associated with an increased risk of PD.
Drug-induced parkinsonism
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:

Parkinsons Disease And Sex Issues: Libido Sex Drive
Parkinsons disease and sex is a complicated topic. No matter your age, gender or relationship status, sex plays a significant part in many peoples lives. Sexual desire does not go away with a diagnosis of Parkinsons disease, and most people are perfectly able to continue having intimate relationships. However, you may experience changes to your libido or physical ability during sex. As with all Parkinsonian symptoms, it helps to be prepared so that youre aware of your options. With this in mind, heres what to expect from Parkinsons disease and sex.
Symptoms Of Parkinsons Disease
Parkinson’s disease has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Stiffness of the limbs and trunk
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Other symptoms may include depression and other emotional changes difficulty swallowing, chewing, and speaking urinary problems or constipation skin problems and sleep disruptions.
Symptoms of Parkinsons and the rate of progression differ among individuals. Sometimes people dismiss early symptoms of Parkinson’s as the effects of normal aging. In most cases, there are no medical tests to definitively detect the disease, so it can be difficult to diagnose accurately.
Early symptoms of Parkinson’s disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinson’s. They may see that the person’s face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s often develop a parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward, and reduced swinging of the arms. They also may have trouble initiating or continuing movement.
