What Are The Primary Motor Symptoms Of Parkinsons Disease
There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.
It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.

What Is Parkinsons Disease
Parkinsons disease is a nervous system disease that affects your ability to control movement. The disease usually starts out slowly and worsens over time. If you have Parkinsons disease, you may shake, have muscle stiffness, and have trouble walking and maintaining your balance and coordination. As the disease worsens, you may have trouble talking, sleeping, have mental and memory problems, experience behavioral changes and have other symptoms.
What Are The Signs And Symptoms Of Parkinsons Disease
Although individuals may experience symptoms differently, the four common signs of Parkinsons disease are:
- Muscle rigidity or stiffness when the arm, leg, or neck is moved back and forth.
- Tremorsinvoluntary movement from contracting musclesespecially when at rest.
- Slowness in initiating movement.
- Poor posture and balance that may cause falls or problems with walking.

Every day, millions of people take selfies with their smartphones or webcams to share online. And they almost invariably smile when they do so.
To Ehsan Hoque and his collaborators at the University of Rochester, those pictures are worth far more than the proverbial thousand words. Computer vision softwarebased on algorithms that the computer scientist and his lab have developedcan analyze the brief videos, including the short clips created while taking selfies, detecting subtle movements of facial muscles that are invisible to the naked eye.
The software can then predict with remarkable accuracy whether a person who takes a selfie is likely to develop Parkinsons diseaseas reliably as expensive, wearable digital biomarkers that monitor motor symptoms. The researchers technology is described in Nature Digital Medicine.
Though ethical and technological considerations still need to be addressed, the Gordon and Betty Moore Foundation has agreed to fund this novel research through a $500,000 grant, effective November of 2021.

What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
Software Analyzes Facial Expressions Hand Movements
Smiles are not the only behaviors that Hoque and his lab can analyze for early symptoms of Parkinsons disease or related disorders.
In collaboration with Ray Dorseya leading expert in Parkinsons disease and the David M. Levy Professor of Neurology at Rochesterand the Universitys Morris K. Udall Parkinson Disease Research Center, the researchers have developed a five-pronged test that neurologists could administer to patients sitting in front of their computer webcams hundreds of miles away.
This could be transformative for patients who are quarantined, immobile, or living in underdeveloped areas where access to a neurologist is limited, Hoque says.
In addition to making the biggest smile, and alternating it with a neutral expression three times, patients taking the test are also asked to:
- Read aloud a complex written sentence
- Touch their index finger to their thumb 10 times as quickly as possible
- Make the most disgusted look possible, alternating with a neutral expression, three times
- Raise their eyebrows as high as possible, then lower them as far as they can, three times slowly
Using machine learning algorithms, the computer program showswithin minutesa percentage likelihood from each of the tests whether the patient is showing symptoms of Parkinsons disease or related disorders.
Hence the importance of testing other expressions and movements, according to Ali, a former postdoctoral associate in Hoques lab who now is an associate data scientist at Sysco.

How Is Constipation An Early Warning Sign Of Parkinson’s It’s Such A Common Problem
A: It’s not as specific as other prodromal symptoms, like anosmia. The rate at which people with chronic and unexplained problems with constipation develop Parkinson’s disease is not as easy to pin down. But if someone has unexplained, persistent constipation, it should at least be noted, as it could be considered prodromal.
Stooping Or Hunched Posture
People who have Parkinsons disease may notice changes in their posture due to other symptoms of the disease, such as muscle rigidity.
People naturally stand so that their weight is evenly distributed over their feet. However, people who have Parkinsons disease may start bending forward, making them appear hunched or stooped over.

Other Diseases That Have Similar Symptoms To Parkinsons Disease
Now, I just want to address something you may have noticed here. Many of these symptoms and signs could also apply to other diseases. Is it an overreaction to assume that if your dog twitches a bit it is definitely Parkinsons disease?
Well yes and no. Certainly, all of these symptoms could indicate other ailments.
Lets go through a few now:
- Generalized tremor syndrome: Yep, its a thing! Your dog may tremor for no real reason. This doesnt have the same stiffness and limited joint mobility that Parkinsons does.
- Kidney disease: Kidney disease can cause depression, anxiety, and tremoring. Youll most likely see vomiting and infrequent urination come with this and can lead to euthanasia.
- Arthritis: A friend of mine has an arthritic dog and stiffness is a real problem. Having inflexible joints can also cause your dog to limp. Arthritis is differentiated by joint pain so your dog may be more vocal if this is what they are suffering.
- Seizure disorders: Did you know that dogs can suffer from epilepsy? Seizures can be caused by all kinds of things. They can also be the entire ailment all by themselves.
As you can see, the signs of Parkinsons in dogs could belong to an entirely different diagnosis. So, if you notice stiffness or tremoring, it is best to have your professional veterinarian make a formal diagnosis.
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 Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
Tips For Better Sleep
- Keep a regular sleep schedule go to bed at the same time and get up at the same time.
- Choose your bedtime based on when you want to get up. Plan to spend seven to eight hours a night in bed.
- Make a bedtime routine for example, snack, bath, tooth-brushing, toileting and follow it every evening.
- Spend time outdoors and exercise every day, in the morning if possible. Avoid exercise after 8:00 p.m.
- If you cant get outdoors, consider light therapy sitting or working near a light therapy box, available at drug stores and department stores.
- If you nap, try to do so at the same time every day, for no more than an hour, and not after 3:00 p.m.
- Sleep in a cool dark place and use the bed only for sleeping and sexual activity.
- Do not read or watch television in bed.
- Use satin sheets and pajamas to make moving in bed easier.
- Minimize drinking liquids for three hours before bedtime to avoid frequent nighttime urination.
- Go to the bathroom immediately before retiring.
- Place a commode next to the bed, to minimize the effort, and light to get up during the night.
- Avoid:
- Alcohol, caffeine and other stimulants such as nicotine
- Heavy late-night meals
- Heavy exercise within six hours of bedtime
- Thoughts or discussions before bedtime about topics that cause anxiety, anger or frustration
- Clock watching
- Screen time television, phones, tablets one or two hours before bed.

Living With Parkinson’s Disease
As Parkinson’s develops, a person who has it may slow down and won’t be able to move or talk quickly. Sometimes, speech therapy and occupational therapy are needed. This may sound silly, but someone who has Parkinson’s disease may need to learn how to fall down safely.
If getting dressed is hard for a person with Parkinson’s, clothing with Velcro and elastic can be easier to use than buttons and zippers. The person also might need to have railings installed around the house to prevent falls.
If you know someone who has Parkinson’s disease, you can help by being a good friend.
How Is Parkinsons Diagnosed
Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.
Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
The Michael J. Fox Foundation has made finding a test for Parkinsons disease one of our top priorities.

Depression May Be An Early Symptom Of Parkinsons
Depression is one of the most common, and most disabling, non-motor symptoms of Parkinsons disease. As many as 50 per cent of people with Parkinsons experience the symptoms of clinical depression at some stage of the disease. Some people experience depression up to a decade or more before experiencing any motor symptoms of Parkinsons.
Clinical depression and anxiety are underdiagnosed symptoms of Parkinsons. Researchers believe that depression and anxiety in Parkinsons disease may be due to chemical and physical changes in the area of the brain that affect mood as well as movement. These changes are caused by the disease itself.
Here are some suggestions to help identify depression in Parkinsons:
- Mention changes in mood to your physician if they do not ask you about these conditions.
- Complete our Geriatric Depression Scale-15 to record your feelings so you can discuss symptoms with your doctor. Download the answer key and compare your responses.
- delusions and impulse control disorders
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.

Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.
Other Typical Symptoms Of Parkinson’s
Tremor is an uncontrollable movement that affects a part of the body. A Parkinsons tremor typically starts in the hand before spreading to affect the rest of the arm, or down to the foot on the same side of the body.
There is no cure for a tremor, but there are ways to manage the symptom with support from a specialist or Parkinsons nurse.
Slowness of movement also known as bradykinesia may mean that it takes someone with Parkinson’s longer to do things. For example, they might struggle with coordination, walking may become more like a shuffle or walking speed may slow down.
Everyday tasks, such as paying for items at a check-out or walking to a bus stop, might take longer to do.
Parkinsons causes stiff muscles, inflexibility and cramps. This can make certain tasks such as writing, doing up buttons or tying shoe laces, hard to do. Rigidity can stop muscles from stretching and relaxing. It can be particularly noticeable, for example, if you struggle to turn over or get in and out of bed.
Symptoms and the rate at which they develop will vary from person to person. The most important thing to do if youre worried you have Parkinsons is to speak to your GP.

Medicines For Parkinson’s Disease
Medicines prescribed for Parkinson’s include:
- Drugs that increase the level of dopamine in the brain
- Drugs that affect other brain chemicals in the body
- Drugs that help control nonmotor symptoms
The main therapy for Parkinson’s is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brain’s dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapysuch as nausea, vomiting, low blood pressure, and restlessnessand reduces the amount of levodopa needed to improve symptoms.
People with Parkinson’s should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, such as being unable to move or having difficulty breathing.
Other medicines used to treat Parkinsons symptoms include:
- Dopamine agonists to mimic the role of dopamine in the brain
- MAO-B inhibitors to slow down an enzyme that breaks down dopamine in the brain
- COMT inhibitors to help break down dopamine
- Amantadine, an old antiviral drug, to reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity
