How To Recognize The Early Signs Of Parkinsons Disease
A neurological disorder, Parkinsons disease progresses slowly over the course of several years. Early symptoms of the condition may not necessarily be linked with this specific disease. Nevertheless, it is important to recognize the early signs of Parkinsons disease, such as the ten that follow.
Dopamine is an essential component to movement and coordination. When brain cells that produce dopamine begin to die, Parkinsons disease can emerge. Low levels of dopamine in the brain causes various symptoms, and disease progression can differ from person to person.
One risk factor for Parkinsons disease is age. Seniors who develop the condition are usually around 60 years old. A smaller number of people, approximately 5 to 10 percent, can develop early-onset Parkinsons, which starts before these individuals turn 50.
Genetics, too, play a role in the development of the disease, albeit a smaller one. About 15 percent of Parkinsons cases are caused by genetics. Researchers conclude that the disease is caused by a combination of genetics, lifestyle, and environment.
Parkinsons disease presents itself in varied ways. In fact, no two seniors experience the disease in the same way. This makes it difficult to determine if symptoms are related to Parkinsons. Symptoms can also be misinterpreted as being a normal part of agingwhich they are not.
Is Early Diagnosis Possible
Experts are becoming more aware of symptoms of Parkinsons that precede physical manifestations. Clues to the disease that sometimes show up before motor symptoms and before a formal diagnosis are called prodromal symptoms. These include the loss of sense of smell, a sleep disturbance called REM behavior disorder, ongoing constipation thats not otherwise explained and mood disorders, such as anxiety and depression.
Research into these and other early symptoms holds promise for even more sensitive testing and diagnosis.
For example, biomarker research is trying to answer the question of who gets Parkinsons disease. Researchers hope that once doctors can predict that a person with very early symptoms will eventually get Parkinsons disease, those patients can be appropriately treated. At the very least, these advances could greatly delay progression.
A Tool For Evaluating Facial Expression For Early Diagnosis Of Parkinson’s Disease
Study Rationale:The hypomimia — decreased facial expression with reduced blinking — is a major motor sign of Parkinson’s disease . This clinical sign indicates movement dysfunction early in the course of PD, thus representing an extremely sensitive biomarker . The goal of FACE-PD project, which stands for Facial expressivity Automatic Classifier for Early detection of Parkinson’s Disease, is to develop a tool for automatic detection of hypomimia. We am to develop an essential tool for detecting Parkinson’s before or immediately after the onset of symptoms.
Hypothesis:We hypothesize that hypomimia is a sensitive biomarker of PD and that its automated detection will allow us to objectively measure this disease sign.
Study Design:This study will include three steps. Firstly, we will develop an automatic tool for detection of facial expressivity . Next, we will use this tool in a group of 50 people with Parkinson’s and 50 healthy people. During this step, the FACE-PD classifier will be tested to confirm its usefulness in clinics and to obtain a score for facial expression in order to correctly distinguish between people with and without Parkinson’s. Finally, this tested version of FACE-PD classifier will be used in another group of people consisting of individuals at high risk of PD, such as people with Rapid Eye Movement sleep behavior disorder.

Early Signs Of Parkinsons And Diagnosis
Early symptoms are a sign that it may be time to see a neurologist to determine if the condition can be diagnosed as PD. Although doctors can test physical agility and muscle tone, there are no definitive lab tests to confirm a Parkinsons diagnosis. Signs that may seem like PD symptoms can also be due to side effects from drugs, essential tremor, or other neurological conditions.
Doctors will look for symptoms that correlate with the condition. An MRI test and a DaTscan may be used to examine the brain and dopamine function. Sometimes, a health care provider may recommend trying a Parkinsons medication, such as levodopa/carbidopa, to see if there is a positive response.
How Is Parkinson’s Disease Diagnosed
Diagnosis is difficult at every stage of the disease, but particularly in the early stages. No single test can provide a diagnosis. A diagnosis will likely involve physical and neurological examinations, conducted over time to assess changes in reflexes, coordination, muscle strength, and mental function. Your doctor might also see how you respond to medicine.
You may need to have brain imaging tests to rule out other conditions that might be causing your symptoms. Such tests could include MRI and CT scans and possibly some other types of scans. Blood tests may also be done to exclude other illnesses.

Early Symptoms Of Parkinsons Disease
Parkinsons disease is a progressive disease of the nervous system that affects movement. Approximately 1 million people in the U.S. are living with the disease. This year, about 60,000 more will be diagnosed with Parkinsons disease.
Many people associate Parkinsons disease with tremors or shaking of their hands. While this is a common symptom, other important symptoms include stiffness of muscles and slowing of movement.
Symptoms of Parkinsons disease usually start on one side of the body. They usually remain worse on that side even after symptoms begin to affect both sides.
The early signs and symptoms are different for each person. The symptoms may be mild enough to go unnoticed for months or years.
Here are early symptoms that can raise concern for Parkinsons disease:
- Smaller handwriting
- Family members may observe that one arm swings less on one side when walking.
- Soft or low voice Again, it is family members or friends who may ask one to speak louder. The speech may be more of a monotone without the usual inflections.
It is the combination of several symptoms that would raise suspicion for Parkinsons disease. A single symptom is not enough to make a diagnosis of Parkinsons disease.
It is important to talk with your health care provider if you have any of the symptoms associated with Parkinsons disease. This is to properly diagnose the condition and rule out other conditions with similar symptoms.
What Are The Symptoms Of Parkinson’s Disease
The main symptoms of Parkinson’s disease are:
- tremor or shaking, often when resting or tired. It usually begins in one arm or hand
- muscle rigidity or stiffness, which can limit movement and may be painful
- slowing of movement, which may lead to periods of freezing and small shuffling steps
- stooped posture and balance problems
The symptoms of Parkinson’s disease vary from person to person as well as over time. Some people also experience:
- loss of unconscious movements, such as blinking and smiling
- difficulties with handwriting
- drop in blood pressure leading to dizziness
- difficulty swallowing
Many of the symptoms of Parkinson’s disease could be caused by other conditions. For example, stooped posture could be caused by osteoporosis. But if you are worried by your symptoms, it is a good idea to see your doctor.

Appears Earlier Than Motor Symptomsdepression Anxiety Heightened Alertness
Most people mention Parkinsons disease, and they usually focus on the symptoms of dyskinesia. However, non-dyskinetic symptoms such as depression and insomnia are sometimes accompanied by symptoms of dyskinesia The patient had depression before it appeared.
Dr. Lin Qiyu pointed out that emotional problems such as depression and anxiety, as well as sleep disorders, loss of smell, severe constipation, etc., may be early warning signs of Parkinsons disease. Its just bad mood. As the disease progresses, some patients develop mental symptoms such as dementia and hallucinations, which lead to barriers to communication with their families, and caregivers need to spend more energy on long-term care.
At present, there are existing treatment drugs to help improve Parkinsons disease complicated with depression. Patients can discuss medication strategies with doctors according to the course of the disease to achieve better treatment effects.
What Sets Young Onset Parkinsons Apart From A Diagnosis At An Older Age
Because the majority of people who get Parkinsons disease are over the age of 60, the disease is often overlooked in younger people, leading many to go undiagnosed or misdiagnosed for extended periods of time.
However, once it has been diagnosed, the rate of the diseases progression is usually much slower in younger than older people, due in part to the fact that younger people have fewer general health problems and are more capable during physical therapy treatment.
Symptoms of young onset Parkinsons disease
While common symptoms of Parkinsons may be similar no matter what age you are, the progression is often different:
- Young people often have more involuntary movement problems due to the most commonly prescribed Parkinsons disease medication, levodopa. For this reason, young onset patients are usually initially treated with alternatives to levodopa.
- Other problems associated with Parkinsons such as memory loss, confusion, and balance difficulties tend to be less frequent in young people with the disease.

Can Doctors Miss The Early Signs Of Parkinsons Disease
Yes, doctors are human.
There has been a tremendous increase in human knowledge over recent years. It is not possible for a single person to recognize all the symptoms of all the diseases.
Thus, when a patient only has the early symptoms of Parkinsons disease, the diagnosis of Parkinsons disease is often missed.
As noted above, the early symptoms of Parkinsons disease can be vague.
Even if you have some of these symptoms, your diagnosis needs to be confirmed by a physical examination. This examination detects the early signs of Parkinsons disease.
Sometimes when the doctor examines you, everything might be perfectly normal. This may be due to one of two things:
The last thing to make sure is that you dont have a disease that can mimic Parkinsons disease. This can lead to misdiagnosis.
If the doctor is not sure, a test called Trodat/F-Dopa scan may help with diagnosis
Issues With Early Diagnosis
The problems with diagnosing PD arise because there is no definitive test, and currently the disease diagnosis must be based on clinical and observational criteria only. Many of the symptoms of PD are imprecise and also common to other diseases, both neurodegenerative and non-neurodegenerative in nature. Evaluation may be performed using the Unified Parkinsons Disease Rating Scale , a tool based on a score derived from the neurological evaluation that is performed by a physician, and hence it is a subjective measure which leads to a lack of objectivity, repeatability and sensitivity in the scale .

Tremor In Other Conditions
While tremor is a common symptom of Parkinsons, it can also be a symptom of other conditions, most notably essential tremor. The main difference between Parkinsons tremor and most other types of tremor is that in Parkinsons resting tremor is most common. Other conditions are usually characterized by action tremor, which tends to lessen at rest and increase when youre doing something, like trying to make a phone call or take a drink.
Tremors of the head and voice are also common in essential tremor but rare in Parkinsons.
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 drinking caffeinated beverages is 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.
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:

Tips For Caring For Someone With Parkinsons Disease
Caring for a loved one with early onset Parkinsons can be difficult. If youre a caregiver for someone with this condition, its important that you remember your own emotional and physical health.
Not only are you dealing with a difficult diagnosis, youre also managing an increased number of responsibilities. Burnout is common in caregivers, so make sure youre checking in with your own needs.
The Michael J. Fox Foundation Center for Parkinsons Research recommends these tips for caregivers:
Who Gets Parkinsons Disease
As stated previously, men are about 1.5 times more likely to develop Parkinsons disease than women however, although the majority of all patients that get the disease are over 60, the total chance of getting the disease is about 2% to 4% in this age group. Consequently, the disease is not rare but the chances of someone age 60 or over developing the disease is not high.

Trouble Moving Or Walking
Do you feel stiff in your body, arms or legs? Have others noticed that your arms dont swing like they used to when you walk? Sometimes stiffness goes away as you move. If it does not, it can be a sign of Parkinson’s disease. An early sign might be stiffness or pain in your shoulder or hips. People sometimes say their feet seem stuck to the floor.
What is normal?If you have injured your arm or shoulder, you may not be able to use it as well until it is healed, or another illness like arthritis might cause the same symptom.
Improving Your Motor Skills
- Work on your tremor. This may include things like putting a little weight on your hand to help reduce tremor and restore control.
- Improve speech quality by working with a speech therapist .
- Reduce problems with eating and drooling by changing how and what you eat.
- Practice overcoming freezing with various techniques, such as stepping toward a specific target on the ground.
- Be open about sexual function problems. Talk to your doctor about your specific issues. He or she may be able to suggest a change in your treatment, such as a change in your medicine or exercise.

Other Early Symptoms Of Parkinsons
Other neurological symptoms may occur early in the development of PD. Some other early signs of the condition include:
- Facial masking Facial expressions that do not express emotion
- Dizziness and fainting Low blood pressure due to problems with the part of the nervous system that controls automatic body processes
- Balance problems
- Changes in voice
Flat affect was my first symptom, a MyParkinsonsTeam member said. I was normally very animated with a great deal of facial expression. When it dropped off to zero facial expression, my partner couldnt figure out why I was mad at her but denied being so.
Another member talked about her experience with fainting. I was making coffee, and I blacked out the second time it happened to me within the last year, she wrote. I got misdiagnosed for so many years when I had low blood pressure.
Existing Studies Into Parkinsons Biomarkers
It is known that many PD biomarkers can be analysed using various forms of human-computer interaction, including movement and gait analysis, speech analysis, the precision grip and lift test , finger tapping tests , hand and finger movement, and handwriting.
In non-PD subjects, finger tapping frequency declines with advancing age, men tap faster than women, and tapping with the dominant finger is faster than that of the non-dominant finger. The basal ganglia facilitate sequential movement and the sequence of movements, however in PD patients bradykinesia and disturbances of rhythm formation occur which can be assessed by FTT. Using an accelerometer and touch sensor, Yokoe et al. measured 14 parameters of FTT movement, showing clear differences between PD and non-PD patients. By classifying these into both velocity and amplitude parameters and rhythm-related parameters, they found that maximum opening velocity was the most sensitive measure and most closely aligned with the UPDRS FTT score.
A conclusion from previous studies is that PD affects multiple aspects of hand and finger movements and that many of these may be detected through changes in the response characteristics as people type a sequence of text on a computer keyboard.

Testing For Parkinsons Disease
There is no lab or imaging test that is recommended or definitive for Parkinsons disease. However, in 2011, the U.S. Food and Drug Administration approved an imaging scan called the DaTscan. This technique allows doctors to see detailed pictures of the brains dopamine system.
A DaTscan involves an injection of a small amount of a radioactive drug and a machine called a single-photon emission computed tomography scanner, similar to an MRI.
The drug binds to dopamine transmitters in the brain, showing where in the brain dopaminergic neurons are.
The results of a DaTscan cant show that you have Parkinsons, but they can help your doctor confirm a diagnosis or rule out a Parkinsons mimic.
Diagnosing Parkinson’s Disease With Skin Samples Could Lead To Earlier Detection
- Iowa State University
- New research shows a simple skin test can accurately identify Parkinson’s disease, which could lead to earlier detection of the disease and better outcomes for patients. Currently, Parkinson’s disease is diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy. The researchers conducted a blinded study of 50 skin samples using an assay originally designed to detect mad cow disease.
New research shows a simple skin test can accurately identify Parkinson’s disease, demonstrating for the first time the feasibility of the method. Currently diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy, Parkinson’s disease is commonly misdiagnosed early in the disease course, complicating clinical trials of potential treatments.
The study, published in the scientific journal Movement Disorders, shows how a chemical assay can detect clumping of the protein alpha-synuclein in skin samples to help diagnose Parkinson’s disease . The study’s authors said using the assay can lead to earlier detection of PD and better clinical trials.
“Since there’s no easy and reliable test available for the early diagnosis of Parkinson’s disease at present, we think there will be a lot interest in the potential use of skin samples for diagnosis,” said Anumantha Kanthasamy, Distinguished Professor of Biomedical Sciences at Iowa State and lead author of the study.
