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.
How Do I Prevent Falls From Common Hazards
- Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
- Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
- Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
- Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
- Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
- Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.
What Are My Next Steps
If your doctor doesnt diagnose Parkinsons, they can help you find out what the best next step is depending on what condition they suspect. In some cases, treatment may be as simple as changing the dosage of a medication that may be leading to Parkinsons-like symptoms.
Receiving a Parkinsons diagnosis can be overwhelming. If your diagnosis is confirmed, contact a movement disorder specialist as soon as possible. A specialist can help you develop a strategy to delay the onset of more severe disease and manage symptoms youre already experiencing.

What Are The Symptoms Present To Confirm Parkinsons Disease
In order to medically diagnose Parkinsons disease, a minimum of two to four symptoms must be present. The four main symptoms include-
- Acute slowness of movement called Bradykinesia.
- Stiffness or rigidity of the arms, legs and trunk.
- Problems with maintaining body balance and posture which result in falls called postural instability.
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.

Testing For Parkinson’s Disease
There are no blood tests or brain scans that can make the diagnosis of Parkinsons disease. Right now, the diagnosis of Parkinsons disease is still made based on the history and the examination.
In some cases, a doctor may order medical imaging such as a or an to make sure nothing else is happening, but these scans will not show any changes relating to Parkinsons disease.
In 2012, the FDA approved a special kind of brain scan called a DaT scan. In this scan, people receive an injection of a dye and then pictures show if there is a brain problem relating to the chemical dopamine. However, this scan was approved only to help figure out if someone with tremor has a disease in the Parkinson family or if their tremor might be related to a different disease called familial essential tremor.
Most of the time, a neurologist especially a movement disorders specialist can know if someone has a disease in the Parkinson family or familial essential tremor without doing this scan. It is also important to know that this scan cannot help a doctor know if a person has Parkinsons disease or one of the other parkinsonisms. Thus, this scan is only used in a few situations. It is not for everyone who might have Parkinsons disease.

When To See A Doctor
If you’re experiencing more than one of the above symptoms, ask your doctor about screening for Parkinson’s. “Unfortunately, making a PD diagnosisespecially in its early stagesis not easy,” says Beck. “There is not a simple blood test or brain scan that confirms a diagnosis. The presence of bradykinesia , plus either tremor or stiffness/rigidity, will help doctors make a PD diagnosis.”
If you’re diagnosed with Parkinson’s disease by an internist or geriatrician, the Parkinson’s Foundation “strongly recommends following up with a movement disorder specialist for a second opinion,” says Beck. “Movement disorder specialists are neurologists who have specific training in diagnosing and treating PD.” And to get through this pandemic at your healthiest, don’t miss these 35 Places You’re Most Likely to Catch COVID.

What Doctors Look For When Diagnosing Parkinsons
Certain physical signs and symptoms noticed by the patient or his or her loved ones are usually what prompt a person to see the doctor. These are the symptoms most often noticed by patients or their families:
Shaking or tremor: Called resting tremor, a trembling of a hand or foot that happens when the patient is at rest and typically stops when he or she is active or moving
Bradykinesia: Slowness of movement in the limbs, face, walking or overall body
Rigidity: Stiffness in the arms, legs or trunk
Posture instability: Trouble with balance and possible falls
Once the patient is at the doctors office, the physician:
Takes a medical history and does a physical examination.
Asks about current and past medications. Some medications may cause symptoms that mimic Parkinsons disease.
Performs a neurological examination, testing agility, muscle tone, gait and balance.
What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.

Determining Diagnosis Through Response To Parkinsons Medication
If a persons symptoms and neurologic examination are only suggestive of Parkinsons disease or if the diagnosis is otherwise in doubt, the physician may, nevertheless, prescribe a medication intended for Parkinsons disease to provide additional information. In the case of idiopathic Parkinsons, there is typically a positive, predictable response to Parkinsons disease medication in the case of some related Parkinsonian syndromes, the response to medication may not be particularly robust, or it may be absent entirely.
Unfortunately, there are no standard biological tests for the disease, such as a blood test. However, researchers are actively trying to find biomarkers in blood and other bodily fluids that could help confirm the diagnosis.
Gauging Speed Of Movement
Bradykinesia occurs in most people who have Parkinson’s. It may cause a lack of spontaneous facial expression and fewer eye blinks per minute than usual, and your doctor will look for these signs in your physical exam.
Your doctor also may assess your speed of movement by asking you to open and close each hand or tap your index finger against your thumb repeatedly, making large movements as quickly as possible. In people with Parkinson’s disease, the movement may start off fast and precise, but it will deteriorate quickly, becoming slow and limited.
Gait is also another way to test for this. Observing a patient while they walk, noting the length of their stride as well as the speed at which they move, can tell doctors quite a bit. Lack of arm swing is also a feature that appears fairly early in those with Parkinson’s.
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 Parkinsons Diagnosis Criteria Do Doctors Use
Until the 1980s, there was no formal diagnostic criteria for Parkinsons disease. Beginning with James Parkinsons 1817 article, An Essay on the Shaking Palsy, and Margaret Hoehn and Melvin Yahrs description of the five stages of motor progression in 1967, scientists focused on the unique ways Parkinsons disease affects movement. A few scientists also noted non-motor symptoms like issues with automatic body functions, such as heart rate and blood pressure.
With the discovery in the 1950s of levodopa, a drug that gets turned into dopamine in your brain and thus replaces some of the dopamine that is lost due to PD, and the discovery of how dramatically levodopa improves motor symptoms, the medical community continued to focus more of their efforts on defining and treating Parkinsons as a motor condition.7
When To See A Doctor About Parkinsons
There isnt one specific test to diagnose Parkinsons disease. Doctors will usually evaluate your symptoms and perform several tests to determine if you have the condition. If you notice the following early warning signs, then you should see a doctor.
The early warning signs of Parkinsons disease include:
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.

People Who Already Have Pd: Should I Get Tested And What Do I Do With The Results
Up until recently, even people with PD with a very extensive family history of PD would not necessarily receive genetic testing because there were no clear uses for the results. There has been research directed at figuring out whether PD caused by or associated with certain mutations have particular clinical characteristics . However, there remains so much variability in clinical characteristics even among people with the same PD mutation, that there are still no clear practical implications in knowing whether a PD patient harbors a particular mutation. There is also, so far, no difference in treatment or management of PD whether or not the patient harbors one of the known mutations. That may change however, with the advent of clinical trials that target particular mutations.
There are two genes that have received particular attention recently because medications are being developed that target those with mutations of these genes.
GBAis a gene that increases the risk of developing PD. The gene encodes for the GBA enzyme, a protein used by the body to break down cellular products. Having two abnormal GBA genes causes Gauchers disease, which is characterized by the buildup of these cellular products resulting in fatigue, bone pain, easy bleeding and an enlarged spleen and liver. When a person inherits only one abnormal gene, he or she does not develop Gauchers disease, but does incur a small increased risk of PD. Most people with one mutated GBA gene do not develop PD.
What Is The Prognosis For Parkinsons Disease
The rate at which Parkinsons progresses varies from patient to patient. Some patients experience its changes over 20 years or more. While others find the disease advances quicker.
Parkinsons is not a fatal disease. However, secondary complications from symptoms may increase falls, blood clots or pneumonia, which can be life-threatening. These are more common in later stages of Parkinsons.
In general, the average life expectancy of Parkinson’s patients is similar to people without the disease.
Early Signs Of Parkinson’s
Early physical signs include the common motor symptoms: tremor, muscle rigidity and slowness. They may also include the following:
- Symptoms starting on one side of the body
- Change in facial expression
- Failure to swing one arm when walking
- Stooped posture
- Loss of sense of smell
- Depression or anxiety
Some of these symptoms are quite common and by no means exclusive to Parkinsons, so if you have some of them, it does not mean you have Parkinsons.
The Problem Of Missed Diagnosis Or Misdiagnosis
If widely circulated, this skin test could potentially cause a spike in the number of successful diagnoses made every year.
Parkinsons disease is not straightforward to diagnose because diagnosis is based on clinical evaluation, meaning the patient history and physical exam, Miocinovic says. So one has to suspect Parkinsons disease in order to ask the right questions and test for specific disease signs. And early on, symptoms may not clearly point to Parkinsons disease.
Many early symptoms of Parkinsons are dismissed as byproducts of the aging process. In some cases, they are even attributed to another epidemiological cause entirely. Some of these symptoms include:
- Restless leg syndrome
- Reduced sense of smell
Sometimes other disorders early on can mimic Parkinson’s, with a couple of the disorders that commonly are mistaken for Parkinson’s being progressive supranuclear palsy, or PSP, or multiple system atrophy, or MSA, because sometimes early in the course, they can look very similar to Parkinson’s, Simon says. Even movement disorder specialists who think it’s Parkinson’s early in the course aren’t right as often as we’d like to think we are.
This wide margin of error has immense ramifications for the work of the neuroscientists who study the disease in the hope of developing successful treatments.

Trying Parkinsons Disease Medications
One of the features of PD is that it will significantly and consistently improve when you begin taking medication that targets your dopamine system.10 Your doctor may ask you to try taking Parkinsons medication, like carbidopa-levodopa, to help confirm a PD diagnosis. Levodopa is a drug that is converted into dopamine in your brain, replacing some of the dopamine you lose due to the disease. Levodopa is frequently paired with carbidopa, which helps prevent levodopa from breaking down before it reaches your brain. Your doctor will observe if carbidopa-levodopa helps your motor symptoms. Carbidopa-levodopa is typically very effective at treating motor symptoms, so a significant response to the medication used to treat it helps confirm the diagnosis. Parkinsons medications are generally very safe and the risk of taking them is low, while the benefit is great because it might help if you do have Parkinsons and improve your mobility.10
