How To Test For Early Onset Parkinson’s

Is Early Diagnosis Possible

My Experience with how you get diagnosed with Early, Young Onset Parkinson’s Disease?

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.

Parkinson’s Disease and Movement Disorders Center

Our center provides compassionate and timely treatment to patients with movement disorders, such as dystonia, ataxia, essential tremor and similar conditions. But our mission goes beyond patient care excellence. By offering educational events and support groups, we empower patients and caregivers to become better partners in their health.

Can Parkinsons Disease Be Prevented

Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

Who Gets Early Onset Parkinsons Disease

About 10%-20% of those diagnosed with Parkinsons disease are under age 50, and about half of those are diagnosed before age 40. Approximately 60,000 new cases of Parkinsons are diagnosed each year in the United States, meaning somewhere around 6,000 12,000 are young onset patients.

Is it genetic or hereditary?

The cause of Parkinsons disease is not yet known. However, Parkinsons disease has appeared across several generations of some families, which could indicate that certain forms of the disease are hereditary or genetic. Many researchers think that Parkinsons disease may be caused by genetic factors combined with other external factors. The field of genetics is playing an ever greater role in Parkinsons disease research, and scientists are continually working towards determining the cause or causes of PD.

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 .

Diagnosing Early Onset Parkinsons Disease

Scratch &  Sniff Study Tests For Early Onset of Parkinson

There is no single test to detect Parkinsons. A diagnosis may be difficult and take a while. The condition is usually diagnosed by a neurologist based on a review of your symptoms and a physical exam.

A DaTscan to visualize your brains dopamine system may help confirm diagnosis. Blood tests and other imaging tests, such as an MRI scan, dont diagnose Parkinsons. However, they may be used to rule out other conditions.

Gait & Balance Abnormalities

Parkinsons Disease Exam

Patients with Parkinsons disease can develop an alteration of the postural reflexes that causes instability in gait and balance control. Such alterations usually develop later in the course of the illness and are a major cause of disability, especially because of the high risk for falls that derives.

Using the exam to pick up postural instability is of the utmost importance for the management of patients with PD, since it will trigger either a medication adjustment or a physical therapy intervention both aimed at falls prevention.

We have three tests for this part of the PD exam:

1) Standing up from a chair

2) Free walking

3) Provoked pull test maneuver for balance

What Is The Pattern Of Disease In Pd

The onset of PD usually occurs in patients in their sixties, and the disease progresses slowly. Although PD eventually results in severe disability and often dementia, life expectancy is not significantly shortened. Death is often due to secondary problems associated with the disease such as falls, pneumonia, aspiration, and immobility.

Diagnosis In Young Onset Parkinsons

Many young onset patients experience delay in diagnosis given the uncommon age and often different symptoms as outlined below. Similar to late onset patients, the diagnosis is made based on history and clinical examination. There are still no proven diagnostic tests that can definitively diagnose PD. In some cases, other mimics of Parkinsons need to be evaluated for given their increased likelihood in younger patients. Given the complexities, it is important to seek evaluation by a neurologist and in many cases a movement disorder specialist.

In addition, young onset patients are more likely to have a genetic risk factor or cause to their symptoms, especially if there is a family history. Genetic testing can be considered, but should always be done after consulting a physician and in many cases a genetic counselor.

What Causes Parkinsons Disease

Scratch & Sniff Study Tests For Early Onset of Parkinson’s 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.

How To Recognize Early Signs Of Parkinsons Disease

Parkinsons disease is a progressive neurological disease that mainly affects people over 60 years of age. Before we get into the signs and symptoms that can hint at the diagnosis of PD, lets review the areas of the brain that are affected by this nerve-degenerating disease.

The brain has multiple overlapping systems involved in the initiation and execution of smooth, controlled, and coordinated movement. These systems influence and modify motor commands from the primary motor cortex.

There are six major regions of the brain that are involved in modifying movement:

  • Premotor cortex
  • Brainstem
  • Cerebellum
  • These regions of the brain influence the final common pathway of motor commandthe pyramidal system. The pyramidal system consists of the primary motor cortex, the corticospinal tracts, and the corticobulbar tracts.

    Seven Signs Of Early Onset Parkinsons

    There are a series of symptoms that can alert us to the early onset of Parkinsons disease. There are more signs, but were going to focus on these seven:

    • Sleep disorders. The most common disorders are insomnia , restless legs syndrome, and REM sleep behavior disorder.
    • Depression. This is one of the first symptoms to appear and is in fact considered an early indicator of the disease.
    • Other mood changes. In addition to depressive symptoms, anxiety and apathy are very common. These symptoms can negatively influence the desire to seek help and resolution.
    • Cognitive changes. Many people with early onset Parkinsons usually find it difficult to do more than one thing at once. Poor task execution, slower thinking speed, attention and concentration problems, memory problems, and dementia are all symptoms of early onset Parkinsons.
    • Tremors. Although they usually start in the hands, they start in the jaw or on the feet in other patients. The most characteristic thing about these tremors is that they occur at rest.
    • Bradykinesia. This is a gradual loss of spontaneous movement. General movement simply slows down. This is one of the most disabling and frustrating symptoms for those affected.
    • Fatigue. With early onset Parkinsons, the patient feels tired all the time without having exerted themselves at all.

    Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:

    Other symptoms include:

    • Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
    • Handwriting changes: You handwriting may become smaller and more difficult to read.
    • Depression and anxiety.
    • Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
    • Pain, lack of interest , fatigue, change in weight, vision changes.
    • Low blood pressure.

    Common Signs Of Young Onset Parkinsons

    Symptoms of Young Onset Parkinsons are often different from Parkinsons that develops later in life. In young onset Parkinsons the first symptom is often dystonia: involuntary muscle contractions that may cause stiffness, twisting and repetitive motions in the limbs. Leg or foot dystonia is particularly common affecting up to 50 percent of diagnosed young people.

    Many of the more common signs of Parkinsons in the elderly are less common early on in young onset Parkinsons disease, such as tremors, cognitive problems including memory loss and dementia, and loss of balance and coordination.

    What does this task measure?OTS evaluates executive function, spatial planning and working memory based upon the Tower of Hanoi test.What does this task involve?The participant is shown two displays of coloured balls held in stockings suspended from a beam. There is a row of numbered boxes along the bottom of the screen. The participant is asked to solve problems by working out how they would move the balls in the bottom display in order to make them match the arrangements of the ball sin the top display. After some training and practice problems, the participant is asked to work out in their head how many moves the solutions to these problems require, and then touch the appropriate box at the bottom of the screen to indicate their response.Why use this task?Performance on the OTS task by Parkinsons patients is associated with the COMT genotype in the early stages of the disease8. In this sense, the COMT gene is responsible for levels of hormones and communication of neurotransmitters. When the COMT gene is no longer fully functioning, dopamine levels may drop and serotonin may rise. Following this, communication between neurotransmitters can fail. This can lead to an inability to spatially plan as communication within the frontal lobe, responsible for planning, solving and organising, has failed.

    Treatment Of Young Onset Parkinsons Disease

    Young onset patients face unique circumstances regarding medical and surgical treatments of Parkinsons disease. In general, the same medications used to treat late onset Parkinsons patients are used for treatment of young onset patients. However, younger patients are at increased risk for certain side effects compared to elderly patients, most notably excess involuntary movements often of the limbs called dyskinesias with use of levodopa. Therefore, a personalized and individualized approach using other medications instead of, or in conjunction with levodopa is often used to mitigate side effects.

    What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms

    Young Onset Parkinson’s Disease or Early Onset Parkinson’s Disease

    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.

    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.

    Why Is Expert Care Important

    Early expert care can help reduce PD complications. Findings show that 60 percent of people with Parkinson’s fall short of getting the expert care they need. The National Parkinson Foundation has estimated that about 6,400 people with Parkinson’s die unnecessarily each year due to poor care.

    Trained neurologists will help you recognize, treat and manage the disease. Common approaches include medication, surgical treatment, lifestyle modifications , physical therapy, support groups, occupational therapy and speech therapy. The best approach is interdisciplinary care, where you are seen by multiple specialists on a regular basis and all of the specialists talk and arrange the best possible coordinated care. This is what is referred to as a patient-centric approach to Parkinson’s care.

    What Role Do The Basal Ganglia And Dopamine Play In Pd

    When it comes to PD, the basal ganglia are of particular interest. Most of the output from the basal ganglia is inhibitory and acts as a braking system on movement. Their function is far more complex than this, but for simplicitys sake, think of the basal ganglia as providing a tonic inhibitory influence on motor commands.

    To initiate movement, the brake must be lifted. Dopamine acts through the nigrostriatal tract to lift the brake on motor activity and thus allows movement.

    Figure 1. The basal ganglia inhibit voluntary movement until dopamine acts to lift this inhibition.

    Parkinsons disease involves a loss of the cells that provide dopamine input to the basal ganglion, and thus the brakes are essentially left engaged. This is thought to be the mechanism behind one of the principal symptoms of Parkinsons diseasebradykinesia. Thus, patients with PD have a difficult time initiating movement and their movements are slowed .
