Parkinsons The Path To Diagnosis

Neurologist discusses breakthroughs in diagnosis and treatment of Parkinson’s disease

The path to a diagnosis of Parkinsons can be a long and uncertain one. Some people have multiple chronic conditions, making it difficult for doctors to identify whether motor symptoms are caused by a disease or a medication.

Part of the criteria for a Parkinsons diagnosis depends on how symptoms have progressed, when and in what order new symptoms appear, and whether any other condition could be causing them.

Parkinsons is usually diagnosed by a neurologist.Receiving a diagnosis from an experienced specialist in movement disorders lowers the risk of misdiagnosis.

What Does A Neurologist Do

The neurologist will want to know why you came, your medical history, your family history , and what, if anything, in your social and work history may have contributed to your symptoms. Bring a summary of your medical history, including serious and chronic illness, hospitalizations, surgeries, allergies, medications taken, family and personal background, occupational risks, and lifestyle risks. If what you have to talk about is difficult to discuss, practice how to bring it up. If you expect bad news, bring someone supportive with you.

The doctor or his assistant may ask you about your activities of daily living. These include questions about your speech, salivation, swallowing, handwriting, cutting food and handling utensils, dressing, hygiene, turning in bed, falling, freezing, walking, tremor, and sensory symptoms. This review of your daily activities is not a laundry list. Careful and imaginative questioning is very helpful.

It’s helpful for the doctor to obtain specimens of your handwriting and compare them with past samples. This may show when your disease actually began. In some people it’s reassuring to know they had PD for several years before they were aware of their symptoms. This implies their PD is progressing more slowly than they thought.

How Is Parkinson’s Disease Diagnosed

Currently there is no single laboratory or blood test to diagnose Parkinsons Disease. Instead, neurologists generally take a detailed history of the patients symptoms, conduct a physical examination, rule out current and past medications and note patients response to medication that cause improvement in symptoms. Parkinsons Disease can be difficult to diagnose accurately and your neurologist may request brain scans or laboratory tests to rule out other diseases.

Patients In Whom A Diagnosis Of Parkinson’s Disease Was Or Was Not Previously Made

Patients in whom a diagnosis of Parkinson’s disease was previously made had a longer disease duration and greater disease severity , with more severe akinesia , postural instability, and rigidity than those in whom the diagnosis was not made before. They were also more likely to be depressed , to have experienced dyskinesias , and to live alone or with their family than in a nursing home .

What are the diagnostic criteria for Parkinson

The American Academy of Neurology is the world’s largest association of neurologists and neuroscience professionals, with 36,000 members. The AAN is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, concussion, Parkinson’s disease and epilepsy.

What Treatments Are Available For Parkinsons Disease

Medications are available that can reduce symptoms of Parkinsons disease to give you a higher quality of life. Some medications act as a replacement for dopamine, which can improve your mobility and overall functionality.

Interestingly, medications may also be a part of the diagnostic process. By prescribing a certain medication, your Michigan Neurology Associates & PC physician can determine if this type of therapy has any effect on your symptoms to confirm Parkinsons disease.

Its also important that you continue to eat a healthy diet and stay physically active to improve the strength and health of your muscles. Your physician can assess your fall risk as symptoms progress to prevent additional medical complications and injuries. Physical therapy may also help you slow down the progress of Parkinsons disease.

Parkinsons disease can take an emotional toll, and to ensure you have the support you need, the staff at Michigan Neurology Associates & PC offer resources to help you cope, including the services of a staff psychologist.

What Is Parkinsons Disease

Parkinsons disease impacts motor function, or how a person moves. It often includes tremors , slowing of movements, and rigidity or stiffness. It can also cause problems with vision, speech, and mentation.;Parkinsons disease gets worse over time.

Parkinsons disease happens when a certain brain chemical level drops. This brain chemical is called dopamine. The lack of dopamine leads to Parkinsons symptoms.

Referral To A Specialist

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.

Brain Imaging Can Help With Diagnosis

Pastest MRCP Part 1 Neurology: Parkinson’s Disease

Doctors use two tests that take detailed pictures of your brain. Each one may help your doctor make a diagnosis. These tests are:;

  • PET scan: This shows how your brain functions. It shows how the brain uses sugar. This scan can help tell the difference between Parkinson’s and .;
  • DaTscan: This shows problems with brain cells that make dopamine. Healthy brain cells light up during the test. Cells without enough dopamine appear dark. This scan can help your doctor tell the difference between Parkinson’s and a brain disease called .

Imaging studies are a newer way to diagnose Parkinson’s. However, not every healthcare facility can do them. It takes an experienced doctor to interpret the scans accurately. These scans also can be very expensive. Be sure to check with your insurance company ahead of time to see whether you are covered and what your out-of-pocket costs will be.;

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.

Treatment Of Parkinsons Disease

There is not a cure for Parkinsons disease. The goal of treatment is to maintain quality of life and reduce the severity of symptoms. At Mercy Health, a team of specialists including neurologists, neurosurgeons, social workers, speech pathologists, physical therapists, dietitians and internists who work together to treat Parkinsons disease.

A common treatment for Parkinson’s disease in deep brain stimulation. Deep brain stimulation is a neurological procedure used to treat late-stage Parkinsons disease patients who are not responding to medications. Goals of the procedure are to reduce symptoms such as tremors, rigidity, stiffness, slowed movement and walking problems.

During the procedure, a lead is placed in the area of the brain that is causing your symptoms. The lead is attached to a pulse generator that is implanted in the chest. The pulse generator sends signals to the brain that block the nerve signals that cause Parkinsons disease symptoms.

Medication for treating Parkinson’s disease

The other most common type of treatment for Parkinson’s disease is medication. There are a variety of medications that may be used to treat Parkinsons disease. Parkinsons disease medications include:

Over time, medications may become less effective in treating the condition and may have to be used in conjunction with other medications. Or, dosages may have to be titrated up or down depending on symptoms.

Response To Medication Can Matter

Other movement disorders can act like Parkinson’s. That makes it hard to know for sure whether you have the disease, even after a complete exam. However, the loss of dopamine causes Parkinson’s. It’s a chemical made by brain cells. It is important for movement.;

For this reason, your doctor may want you to take a dopamine replacement drug called levodopa. Then your doctor will watch to see whether your symptoms improve. If you get better on levodopa, it’s more likely that you have Parkinson’s.;

How Was The Study Done

Parkinsons disease

Between October 2010 and February 2011, Rajabally and Martey searched for 2 groups of patients. The first were people with PD. The second group included people who had other neurologic illnesses . The reason they needed to select 2 groups was for comparison.

There are many causes for polyneuropathy. The most common causes are diabetes and long-term alcohol use or abuse. In addition, vitamin deficiencies can cause a polyneuropathy. As the authors were searching for people to study, they excluded those who had diabetes, alcoholism, or a known vitamin deficiency. In this way, they were able to minimize other factors which might make the results more confusing.

Rajabally and Martey identified 37 people with PD. They matched these people with 37 people who were the same age and gender. Both groups were studied in exactly the same way. The participants had blood testing to look for vitamin levels, possible diabetes , and other medical illnesses. Each person had a detailed nerve test called an electromyogram. This test is one way to measure the severity of the nerve problem. Since levodopa was a possible cause of the polyneuropathy, the authors carefully measured the time that the people with PD had been taking this medication.

What Does This Mean

Rajabally and Martey found that people with PD were more likely to have a polyneuropathy than people with other neurologic illnesses. There was a relationship between low vitamin B12 levels and the presence of the nerve problem. There also seemed to be a relationship between the duration of PD and the neuropathy. However, they did not find a clear link between the duration of treatment with levodopa and the occurrence of the neuropathy. Because of this, they were unable to conclusively prove that levodopa causes a polyneuropathy. However, their findings are very important because they showed that more people with PD have polyneuropathy and low vitamin B12 levels. This suggests that doctors need to check vitamin B12 levels in each person with PD.

What Was The Study About

In their article, Neuropathy in Parkinson disease: Prevalence and determinants, Rajabally and Martey take a closer look at a problem that has been discussed for several years., The problem is very specific. Some people with Parkinson disease develop something called a polyneuropathy. This is a problem of the nerves in the feet and hands. It starts gradually, and over a long period of time, gets worse. When it happens, it usually affects the feet first, and later, the hands. Both are affected equally. One concern is that the medication that is used most often for PD may be the cause of the nerve problem. This medication is called levodopa. In other words, the treatment of one illness may be the cause of a second illness. Because this association is unclear, the authors decided to look more closely at the relationship between levodopa and polyneuropathy.

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.

Brain Imaging And Other Tools To Aid Diagnosis Of Parkinsons

Motor Symptoms of Parkinson’s Disease with Dr. Abdul Rana, Neurologist

In addition to taking a history and performing a detailed neurologic examination, physicians sometimes use brain imaging to help support a particular diagnosis. However, these studies have their limitations in the diagnosis of Parkinsons disease and are typically used only in select patients. Brain imaging is not routinely performed by neurologists or movement disorder specialists when they are considering a diagnosis, especially if the persons symptoms strongly suggest to the physician that idiopathic Parkinsons disease is the correct diagnosis.

Helping diagnose Parkinsons with DaTscan and other tests

Rather, use of imaging is most helpful when the diagnosis is uncertain, or when physicians are looking for changes in the brain that are more typical of one of several Parkinsonian syndromes and other conditions that can mimic Parkinsons. Imaging studies to evaluate Parkinsons disease and Parkinsonian syndromes include magnetic resonance imaging , which examines the structure of the brain, and DaTscan, an imaging test approved by the Food and Drug Administration to detect the dopamine function in the brain. A DaTscan may help differentiate idiopathic Parkinsons disease from certain other neurologic disorders. Most physicians offices will have access to MRI; however, DaTscan imaging may only be available at larger hospitals or medical centers.

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.

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.;

Parkinsons Disease: Symptoms, Diagnosis and Treatment ...

I first suspected there was something wrong when I was travelling and I was writing a postcard to a friend of mine in, in Australia whose name is Anthony Diecopolis. And, and I got to the Anthony Diec and I couldnt finish the opolis. And its very strange my hand had sort of gone into a sort of spasm and it just wouldnt, wouldnt finish writing the, the, the word. And so thats a bit strange.

And so I went when, when I got I, I went to the doctor and said, What on earths going on? And I had since then Id also developed this slight tremor in my right hand. He said, Well its probably, Essential Tremor or trapped nerve or something like that. And anyway, then it got a bit worse and then I was, I was recommended to go to a neurologist. And the neurologist had a look at me and gave me some pills. And he said, Come back and tell me if these work.

This is about, about sort of, nine months after my, my not being able to finish the, the postcard. And, and he said, Take these pills. And the pills worked. Magically the tremors stopped and I thought this is wonderful. And so I went back to the neurologist and I said, Yes everythings fine now. The pills have, the pills have worked. And far from looking happy about this he looked rather, rather grave and he said, I think youd better go to another neurologist.
