How To Diagnosis Parkinson’s Disease

What Can I Expect If I Have This Condition

Diagnosing Parkinson’s Disease by Dr. Steve McGee (Stanford Skills Symposium)

Parkinsons disease is a degenerative condition, meaning the effects on your brain get worse over time. However, this condition usually takes time to get worse. Most people have a normal life span with this condition.

You’ll need little to no help in the earlier stages and can keep living independently. As the effects worsen, youll need medication to limit how the symptoms affect you. Most medications, especially levodopa, are moderately or even very effective once your provider finds the minimum dose you need to treat your symptoms.

Most of the effects and symptoms are manageable with treatment, but the treatments become less effective and more complicated over time. Living independently will also become more and more difficult as the disease worsens.

How long does Parkinsons disease last?

Parkinsons disease isnt curable, which means its a permanent, life-long condition.

Whats the outlook for Parkinsons disease?

Parkinson’s disease isn’t fatal, but the symptoms and effects are often contributing factors to death. The average life expectancy for Parkinson’s disease in 1967 was a little under 10 years. Since then, the average life expectancy has increased by about 55%, rising to more than 14.5 years. That, combined with the fact that Parkinson’s diagnosis is much more likely after age 60, means this condition doesn’t often affect your life expectancy by more than a few years .

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.

Causes Of Parkinsons Disease

At present, we do not know the cause of Parkinsons disease. In most people there is no family history of Parkinsons Researchers worldwide are investigating possible causes, including:

  • environmental triggers, pesticides, toxins, chemicals
  • genetic factors
  • combinations of environment and genetic factors
  • head trauma.

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.

Testing For Parkinson’s Disease

Diagnosing Parkinsons disease: Physical examination Your doctor will ...

The exam for Parkinson’s disease is based on the review of your medical history, but diagnostic imaging may be used to rule out other diseases that are easily mistaken for Parkinson’s disease.

CT and MRI scans can be used to rule out the possibility of other brain diseases besides Parkinson’s disease .Your doctor might also perform a test called an MIBG myocardial scintigraphy, which is used to examine the condition of sympathetic nerves in the heart. For this, you take a test agent containing a substance called metaiodobenzylguanidine, which is similar to norepinephrine . The degree to which this agent collects in the heart is then assessed using images. It is known that this agent does not collect in the heart in Parkinson’s disease patients, and this fact is used as a reference in making a diagnosis.

In January 2014, a testing procedure called dopamine transporter became available in Japan. DAT is a protein that encourages the recycling of the dopamine that is used to send signals in the brain. This test discriminates between conditions such as Parkinson’s disease and dementia with Lewy bodies by visualizing the workings of DAT.

How Is Parkinsons Disease Diagnosed

Your doctor will ask questions about your symptoms and your past health and will do a neurological exam. This exam includes questions and tests that show how well your nerves are working. For example, your doctor will watch how you move. He or she will check your muscle strength and reflexes and will check your vision.

Your doctor also may check your sense of smell and ask you questions about your mood.

In some cases, your doctor will have you try a medicine for Parkinsons disease. If that medicine helps your symptoms, it may help the doctor find out if you have the disease.

Tests

There are no lab or blood tests that can help your doctor know whether you have Parkinsons. But you may have tests to help your doctor rule out other diseases that could be causing your symptoms. For example:

  • An MRI or CT scan is used to look for signs of a stroke or brain tumor.
  • Blood tests check for abnormal thyroid hormone levels or liver damage.

Another type of imaging test, called PET, sometimes may detect low levels of dopamine in the brain. These low levels are a key feature of Parkinsons. But PET scanning isnt commonly used to evaluate Parkinsons. Thats because its very expensive, not available in many hospitals, and only used experimentally.

Physical And Neurological Examination

Your doctor will conduct a physical and neurological examination. This can involve observing your behavior, movements, and mental state and conducting tests or asking you to perform certain exercises.

These are some of the symptoms of Parkinsons your doctor can determine visually:

  • Fewer spontaneous movements or hand gestures
  • Reduced frequency of blinking
  • Tremors in your hands while they are at rest, often only in one hand
  • Hunched posture or forward lean while walking
  • Stiff movements

These are some of the exercises your doctor may ask you to do to evaluate your movements, balance, and coordination:

  • Opening and closing your fist
  • Tapping your fingers, toes, and heels
  • Holding your arms out in front of you
  • Moving your finger from one point to another
  • Rotating your wrists or ankles
  • Standing from a chair

What Are The Early Warning Signs Of Parkinson’s Disease

Parkinsons warning signs can be motor symptoms like slow movements, tremors or stiffness. However, they can also be non-motor symptoms. Many of the possible non-motor symptoms can appear years or even decades ahead of motor symptoms. However, non-motor symptoms can also be vague, making it difficult to connect them to Parkinson’s disease.

Non-motor symptoms that might be early warning signs include:

How Is It Treated And Is There A Cure

Approach to the Exam for Parkinson’s Disease

For now, Parkinsons disease is not curable, but there are multiple ways to manage its symptoms. The treatments can also vary from person to person, depending on their specific symptoms and how well certain treatments work. Medications are the primary way to treat this condition.

A secondary treatment option is a surgery to implant a device that will deliver a mild electrical current to part of your brain . There are also some experimental options, such as stem cell-based treatments, but their availability often varies, and many aren’t an option for people with Parkinsons disease.

How It All Fits Together

Diagnosing Parkinsons disease can be tricky. The process relies heavily on your doctors judgment. In addition, the causes and risk factors of Parkinsons are not entirely clear yet, which contributes to the difficulty in diagnosing this condition.

However, there have been efforts to try and detect this disease earlier. For instance, clinicians have started focusing more on prodromal symptoms, which are early symptoms that appear before movement-related difficulties begin.

These symptoms include:

  • Loss of smell, which can sometimes occur years before other symptoms
  • Chronic constipation, without any other explanation
  • Rapid eye movement behavior disorder, which causes sleep disturbances

Signs Of Parkinsons Disease

At this point, you are probably wondering what signs of Parkinsons you need to be on the lookout for. The following symptoms can all be signs of the early stages of Parkinsons. You should immediately see your doctor for an assessment if you have been experiencing any of them, especially if they have been ongoing for some time or you have been experiencing more than one symptom.

  • Tremors: These tremors occur in a limb at rest, usually the hand or arm.
  • Rigid, stiff muscles: The muscles stiffen up involuntarily, limiting your range of motion. This may occur in the arms, legs and/or torso.
  • Posture instability or balance impairment: You struggle to stand or walk upright, which may result in a stooped posture or trouble with falls.
  • Bradykinesia: This term refers to slowed movement, which makes everyday tasks such as walking or standing up difficult.
  • Loss of automatic movements: Over time, you will struggle with involuntary movements, such as blinking your eyes or smiling.
  • Speech changes: Your speech may become soft or slurred and will often lose its inflections as well.
  • Writing changes: Your handwriting may become small, cramped and difficult to read.

Symptoms usually begin on one side of the body only, and often remain more severe on that side even after the entire body begins showing symptoms. Most diagnoses of Parkinsons are made when at least two and often more of these symptoms are present.

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.

What Is Parkinson’s Disease

parkinson

Parkinsons disease occurs when brain cells that make dopamine, a chemical that coordinates movement, stop working or die. Because PD can cause tremor, slowness, stiffness, and walking and balance problems, it is called a movement disorder. But constipation, depression, memory problems and other non-movement symptoms also can be part of Parkinsons. PD is a lifelong and progressive disease, which means that symptoms slowly worsen over time.

The experience of living with Parkinson’s over the course of a lifetime is unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.

Estimates suggest that Parkinsons affects nearly 1 million people in the United States and more than 6 million people worldwide.

New Diagnostic Standards For Parkinsons

Until recently, the gold-standard checklist for diagnosis came from the U.K.s Parkinsons Disease Society Brain Bank. It was a checklist that doctors followed to determine if the symptoms they saw fit the disease. But thats now considered outdated. Recently, new criteria from the International Parkinson and Movement Disorder Society have come into use. This list reflects the most current understanding of the condition. It allows doctors to reach a more accurate diagnosis so patients can begin treatment at earlier stages.

The Importance Of Early Diagnosis

Early detection and diagnosis is important because the treatments for PD are more effective in the early stages of the disease. In addition, physical therapy and exercise, which greatly improve symptoms and delay progression of the disease, are much easier to perform in the early stages.

Current diagnosis is made through the presence of motor symptoms however, researchers have found that by the time motor symptoms occur, over 60% of all dopamine neurons in the basal ganglia of the brain have been damaged. Non-motor symptoms become apparent in people with PD long before motor symptoms, including sleep disturbances and loss of the sense of smell.3

Active areas of research include looking for markers in the blood, urine, or cerebral spinal fluid that reliably detect PD, called biomarkers. In addition, brain imaging tests that have high sensitivity for detecting PD are also being actively researched.4

Parkinsons Disease: Causes Symptoms And Treatments

Parkinsons disease is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.

Symptoms usually begin gradually and worsen over time. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.

While virtually anyone could be at risk for developing Parkinsons, some research studies suggest this disease affects more men than women. Its unclear why, but studies are underway to understand factors that may increase a persons risk. One clear risk is age: Although most people with Parkinsons first develop the disease after age 60, about 5% to 10% experience onset before the age of 50. Early-onset forms of Parkinsons are often, but not always, inherited, and some forms have been linked to specific gene mutations.

Support For People Living With Parkinsons Disease

How is Parkinson’s disease diagnosed?

While the progression of Parkinsons is usually slow, eventually a persons daily routines may be affected. Activities such as working, taking care of a home, and participating in social activities with friends may become challenging. Experiencing these changes can be difficult, but support groups can help people cope. These groups can provide information, advice, and connections to resources for those living with Parkinsons disease, their families, and caregivers. The organizations listed below can help people find local support groups and other resources in their communities.

When Should I See My Healthcare Provider Or When Should I Seek Care

You should see your healthcare provider as recommended, or if you notice changes in your symptoms or the effectiveness of your medication. Adjustments to medications and dosages can make a huge difference in how Parkinsons affects your life.

When should I go to ER?

Your healthcare provider can give you guidance and information on signs or symptoms that mean you should go to the hospital or seek medical care. In general, you should seek care if you fall, especially when you lose consciousness or might have an injury to your head, neck, chest, back or abdomen.

Tests To Rule Out Other Conditions

Blood tests can help rule out other possible causes of the symptoms, such as abnormal thyroid hormone levels or liver damage.

An MRI or CT scan can check for signs of a stroke or brain tumor, which may cause similar symptoms.

Hydrocephalus due to atrophy can occur with some types of dementia and would be visible with one of these imaging tests. If the person has neurologic symptoms but a normal scan result, Parkinsons disease may be present.

Diagnosis And Management Of Parkinsons Disease

There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.

No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.

People can manage their Parkinsons disease symptoms through:

  • seeing a Doctor who specialises in Parkinsons
  • medication
  • multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
  • deep brain stimulation surgery .

Referral To A Specialist

parkinson

If your GP suspects Parkinson’s disease, you’ll be referred to a specialist.

This will usually be:

  • a neurologist, a specialist in conditions affecting the brain and nervous system
  • a geriatrician, a specialist in problems affecting elderly people

The specialist will most likely ask you to perform a number of physical exercises so they can assess whether you have any problems with movement.

A diagnosis of Parkinson’s disease is likely if you have at least 2 of the 3 following symptoms:

  • shaking or tremor in a part of your body that usually only occurs at rest
  • slowness of movement
  • muscle stiffness

If your symptoms improve after taking a medication called levodopa, it’s more likely you have Parkinson’s disease.

Special brain scans, such as a single photon emission computed tomography scan, may also be carried out in some cases to try to rule out other causes of your symptoms.

Symptoms That May Be Related To Pd But That Few People Know About

People with PD and care partners may suspect that a particular symptom is related to PD, but they cant find information about it, so they are not sure. Two symptoms that pop up in this category are runny nose and breathing problems, which well focus on today. Of course, if these are new symptoms for you, they could be indicative of a new problem, including infection with COVID-19, so make sure to get yourself checked out by your doctor. However, if all else is ruled out, PD could be to blame. Excessive sweating and specific skin disorders are in this category as well and have been addressed previously.
