Is It Parkinson’s Disease Blood Test Might Tell

But new technique needs more study, researchers say

HealthDay Reporter

WEDNESDAY, Feb. 8, 2017 — Measuring a particular blood protein might help doctors easily distinguish Parkinson’s disease from some similar disorders, a new study suggests.

The potential blood test is “not ready for prime time,” Parkinson’s disease experts said. But, it marks progress in the quest for an objective way to diagnose Parkinson’s and similar conditions known as atypical parkinsonian disorders, they noted.

Parkinson’s disease is a movement disorder that affects nearly 1 million people in the United States alone, according to the Parkinson’s Disease Foundation.

The root cause is unclear, but as the disease progresses, the brain loses cells that produce dopamine — a chemical that regulates movement. As a result, people suffer symptoms such as tremors, stiff limbs, and balance and coordination problems that gradually worsen over time.

Right now, there is no blood test, brain scan or other objective measure that can definitively diagnose Parkinson’s, said James Beck, vice president of scientific affairs for the Parkinson’s Disease Foundation.

“In general, Parkinson’s disease is diagnosed with a clinical exam,” Beck explained.

The best person to make that call is a neurologist with expertise in movement disorders, according to Beck.

“But,” he said, “even highly trained doctors initially get it wrong about 10 percent of the time.”

Severe Headaches Are A Main Symptom Of Parkinson’s Disease

There are several common symptoms of Parkinson’s disease, though severe headaches are not one of them. PD is diagnosed when a person has one or more of the four most common motor symptoms of the disease that include resting tremor, slow movement , rigidity, and difficulty balancing when standing . There are other secondary motor and non-motor symptoms that also occur with PD. Symptoms may be experienced differently by each person and the progression of the disease is different for everyone as well. For example, some people may have tremor as a primary symptom, while another may not have tremors but may have postural instability.

There Are No Laboratory Tests To Diagnose Parkinsons Disease

Currently there are no laboratory tests that can diagnose Parkinsons disease. This can make it difficult to accurately diagnose because PD resembles other movement disorders. In order to diagnose PD, a physician will take a complete medical history and perform a neurological exam. Additional testing may be done simply to rule out other neurological conditions that may resemble Parkinsons.

Tips For Caring For Someone With Parkinsons Disease

TEST QUESTION: Parkinson

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:

Symptom History Of Parkinsons Disease

Diagnosis of PD is most often made when a doctor identifies the primary motor symptoms in a patient. Diagnostic criteria for PD called the Unified Parkinsons Disease Rating Scale recommend that the physician assess for symptoms such as tremor, rigidity, balance impairments, freezing episodes , posture, changes in handwriting, difficulty swallowing, and reduced facial expression.3,4

In addition to these primary motor symptoms, the symptom history for diagnosing PD should include investigating the presence of non-motor symptoms of PD, such as constipation, a frequent and urgent need to urinate, sleep disturbances, pain, orthostatic hypotension , reduced sense of smell , sexual dysfunction, and fatigue. In addition, many people with PD experience mood disorders like depression or anxiety and cognitive changes, such as memory difficulties, slowed thinking, or confusion.4,5

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.

What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms

Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.

Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.

Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.

Is Parkinsons Disease Inherited

Early Screening Tools for Parkinsonâs Disease

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.

Important Step But Preliminary

Commenting for Medscape Medical News, James Beck, PhD, chief scientific officer of the Parkinson’s Foundation, said the study “is an important step toward the creation of a new way to potentially diagnose Parkinson’s disease.”

But he cautioned that this is a preliminary study. “To really confirm the possibility of using this approach for diagnosing Parkinson’s, a larger study will be necessary. And it will be important to test this in a population with early disease the most difficult group to accurately diagnose.”

Also commenting on the findings, Beate Ritz, MD, PhD, an epidemiologist at UCLA Fielding School of Public Health in Los Angeles, who is part of a team also working on ways to measure abnormal alpha-synuclein to diagnose Parkinson’s, described the current study of skin samples as “pretty nifty.”

“Their research shows clearly that they can distinguish between Parkinson’s patients and controls in this way,” she said. “The big advantage of this study is that they have brain pathology, so they know exactly which individuals had Parkinson’s.”

Ritz is working with Gal Bitan, PhD, from the UCLA Brain Research Institute on a potential blood test to measure abnormal alpha-synuclein.

The study was funded by the National Institutes of Health and the US Army Medical Research Materiel Command. The study authors, Beck, and Ritz have disclosed no relevant financial relationships.

Diagnosis Of Parkinsons Via Datscan And Clinical Exam Are Similarly Accurate

Despite the DaTscan being available to help diagnose Parkinsons, in most clinical situations, a DaTscan will not add information to what can be gleaned from the clinical exam. One study actually demonstrated that the accuracy of diagnosis in early PD was the same whether the diagnosis was reached using clinical exam or using DaTscan.

Parkinsons Disease is a progressive neurodegenerative disorder affecting both motor and non-motor abilities. It afflicts 1% of those over 60 years of age.XResearch sourceJOHN D. GAZEWOOD, MD, MSPH,D. ROXANNE RICHARDS, MD,KARL CLEBAK, MD, Parkinsons An Update, The American Family Physician, 2013 Feb 15 87:267-273 It is a progressive disorder of the central nervous system. PD is caused by a lack of dopamine, a chemical that helps the parts of your brain responsible for motor function communicate with each other. This condition often causes tremors, muscle stiffness, slowness, and poor balance. If you suspect that you, or someone you love, has Parkinsons, it is important to know how you can diagnose this condition. Begin by trying to identify symptoms of the disease at home, and then see your doctor for an appropriate medical diagnosis.

What Happens At The Exam

Parkinsons disease

If your doctor thinks you might have Parkinsonâs disease, theyll recommend that you see a specialist who works with nervous system issues, called a neurologist. One whoâs also trained in movement disorders, like Parkinsonâs, may be able to make the right diagnosis faster.

Your neurologist will probably want to see how well your arms and legs move and check your muscle tone and balance.

They may ask you to get out of a chair without using your arms for support, for example. They also may ask a few questions:

  • What other medical conditions do you have now or have you had in the past?
  • What medications do you take?
  • Has your handwriting gotten smaller?
  • Do you have trouble with buttons or getting dressed?
  • Do your feet feel âstuckâ to the floor when you try to walk or turn?
  • Do people say your voice is softer or your speech is slurred?

Tell your doctor if youâve noticed a change in your sense of smell or you have trouble with sleep, memory, or mood.

Parkinsonâs disease can look different from person to person. Many people have some symptoms and not others.

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.

Response To Parkinsons Drugs

After examining you, and depending on the severity of your symptoms, your specialist may suggest you take medication for Parkinsons. If your symptoms improve after taking Parkinsons medication for a few weeks or months, your specialist may confirm a Parkinsons diagnosis. However, some people with other forms of parkinsonism will also respond well to these drugs.

Your specialist may suggest you have a scan to help make a diagnosis. However, scans alone cant make a definite diagnosis of Parkinsons, so they are not commonly used.

Diagnosing Parkinsons Disease Accurately

Ensuring accurate diagnoses can be especially challenging when patients are in early stages of their conditions. Early accurate diagnosis is key for the development of preventative treatment options to slow progression of PD, DLB, and MSA. In addition, symptomatic treatment options will differ based on the diagnosis, and patients deserve an answer as soon as possible when facing these potential diagnoses. Patients who have an obvious or well established diagnosis do not need further testing, but for those whose diagnosis is unclear, the use of the Syn-One test can be extremely useful.

Advances such as the use of the Syn-One test as well as the DaTSCAN are just two of the ways that our work at PNI is helping improve the quality of life of our patients and our community.

Ruling Out Other Conditions

Medical School – Parkinson’s Disease

The symptoms of PD are similar to symptoms caused by other conditions, and an important part of the diagnosis process is excluding other diseases that may be the source of the patients symptoms. Other diseases that could cause similar symptoms include stroke, hydrocephalus, or other neurodegenerative disorders. Some medications can also cause Parkinsons like symptoms, and the doctor will assess these. Good responsiveness to levodopa for the motor symptoms is indicative of PD. However, many clinical trials need patients newly diagnosed with PD that have never taken levodopa. So, it may be worthwhile discussing participation in clinical trials with the doctor first.1

Diagnosis Of Parkinsons Disease

A number of disorders can cause symptoms similar to those of Parkinson’s disease. People with Parkinson’s-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson’s, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson’s. Since many other diseases have similar features but require different treatments, it is important to make an exact diagnosis as soon as possible.

There are currently no blood or laboratory tests to diagnose nongenetic cases of Parkinson’s disease. Diagnosis is based on a person’s medical history and a neurological examination. Improvement after initiating medication is another important hallmark of Parkinson’s disease.

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.

Can Parkinsons Disease Be Diagnosed By How You Smell

Blood Test Reveals More Accuracy On Parkinson

Theres evidence that people with Parkinsons disease may emit a specific type of scent, which is related to increased sebum production. However, doctors have not developed a way to use this odor to diagnose the disease. More research is being done to see how the finding can help with diagnosis and treatment.
