If You Have Parkinson’s Disease
If you have been diagnosed with Parkinson’s, call your doctor if:
- You notice any significant change in your symptoms, such as severe episodes of freezingâa sudden loss of mobilityâwhich may affect walking.
- Your response to your medicine changes.
- Any other symptoms occur, such as constipation, sexual problems, or incontinence.
- You have symptoms of depression, such as feeling sad or hopeless and losing interest in daily activities.
- You or your family notice that you have problems with memory and thinking ability.
Peripheral Neuropathy And Parkinsons Disease
A number of studies have tried to determine if PN is more common among people with PD as opposed to people without PD. PN is a relatively common condition in the general population, which makes it difficult to ascertain whether or not it is even more common among people with PD.
The available studies have varying results and are difficult to compare with each other as they:
- Include different types of populations of people with PD
- Assess peripheral neuropathy differently
- Assess for causes of peripheral neuropathy differently
A recent review looked at all the available data and determined that large fiber neuropathy was present in 16% of patients with PD, about double the prevalence of this condition in the general population. Skin biopsy-proven small fiber neuropathy was present in over 50% of people with PD, although this result was based on a small sample of patients.
Living With Parkinson’s Disease
Coming to terms with a diagnosis of Parkinson’s and living with the disease is challenging and will take a lot of adjustment. There are still things you can do that can help you to feel more in control of your situation and to stay positive. Some things that might help could include:
- choosing to lead a healthy lifestyle
- making informed decisions related to your treatment
- keeping a diary of your symptoms in preparation for meetings with health and social care professionals
- attending a self-management course

Further Testing In Parkinson’s
In other situations, where perhaps the diagnosis is not as clear, younger individuals are affected, or there are atypical symptoms such as tremor affecting both hands or perhaps no tremor at all, further testing may help. For example, imaging can play a role in differentiating between essential tremor and Parkinsons. It can also be important to confirm what is initially a clinical diagnosis of Parkinsons prior to an invasive treatment procedure such as surgical DBS
From Evidence To Recommendation
The pathological studies emphasise the need for particular care in making a clinical diagnosis of . There is limited evidence to suggest that the UK Brain Bank Criteria have adequate sensitivity and specificity in comparison with post-mortem findings. The accuracy of diagnosis using the Brain Bank criteria increases as the condition progresses.
The availability of brain tissue has fostered much valuable research in recent years and should be encouraged in the future. Diagnostic information derived from post-mortem examination can also be of value to the families of individual patients.
RECOMMENDATIONS
- R9.
-
should be diagnosed clinically and based on the UK Parkinsons Disease Society Brain Bank Criteria.
- R10.
-
Clinicians should be encouraged to discuss with patients the possibility of tissue donation to a brain bank for purposes of diagnostic confirmation and research.

What Should You Know About At
Genetic tests are not a substitute for a Parkinson’s diagnosis. Most at-home genetic tests do not provide genetic counseling services to help interpret the results. Always consult with a genetic counselor and your doctor before and after taking a genetic test. Most at-home genetic tests check for a limited number of gene mutations associated with Parkinson’s. This can be misleading since these tests may not be comprehensive.
Since scientists are still discovering more PD-associated genes, it is important to consult your doctor about comprehensive genetic testing options, like the PD GENEration study, which provides a free comprehensive genetic test identifying all possible variants in the two most common PD genes.
Even if you or a loved-one test positive for a Parkinson’s gene, it does not mean either of you will develop it. Having a genetic mutation only means that you may be at increased risk to develop PD. Environmental factors and lifestyle choices will help determine whether someone will get Parkinson’s.
Tom Thought That Because Some Pink Tablets Relieved His Symptoms This Meant He Was Ok He Didn’t
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.

What Is Parkinsons Disease
Parkinsons disease is a chronic neurological condition. It is progressive and symptoms worsen over time. It is named after Dr James Parkinson who first described the condition in 1817.
People with Parkinsons disease experience a loss of nerve cells in the part of their brains responsible for controlling voluntary movements. This part of the brain is called the substantia nigra . The nerve cells in the substantia nigra usually produce a chemical called dopamine which helps transmit messages from the brain to the rest of the body via the central nervous system . As these cells are lost, people with Parkinsons disease experience a loss of dopamine and the messages controlling movement stop being transmitted efficiently.
Parkinsons disease is more common as people get older but it can affect younger adults. Men tend to be affected in slightly higher numbers than women.
There Are No Laboratory Tests To Diagnose Parkinson’s Disease
Currently there are no laboratory tests that can diagnose Parkinson’s 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 Parkinson’s.

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.

Brain Imaging And Other Tools To Aid Diagnosis Of Parkinsons
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.

How Can I Try To Get An Early Diagnosis
By the time Parkinsons causes noticeable motor symptoms, usually about 50 percent of the cells that produce dopamine in your substantia nigra have already died off. Non-motor symptoms, such as constipation, loss of smell, or restless sleep, often appear before motor symptoms.
Theres still debate among medical professionals on how long non-motor symptoms may appear before an individual has noticeable changes in their movement. Its thought that they could appear years to decades beforehand.
But a formal Parkinsons diagnosis requires the symptom slowness of movement. In the time before this symptom appears, your doctor cant make a Parkinsons diagnosis, but they may alert you that youre at a high risk of developing Parkinsons in the future if these or other symptoms appear at any point.
Early Signs Of Parkinson’s
Early physical signs include the common motor symptoms: tremor, muscle rigidity and slowness. They may also include the following:
- Symptoms starting on one side of the body
- Change in facial expression
- Failure to swing one arm when walking
- Stooped posture
- Loss of sense of smell
- Depression or anxiety
Some of these symptoms are quite common and by no means exclusive to Parkinsons, so if you have some of them, it does not mean you have Parkinsons.

Eat Fresh Raw Vegetables
If you needed more reasons to eat your vegetables, this should be the clincher. Studies show that increased amounts of the B vitamin folic acid, found primarily in vegetables, can significantly reduce the risk of Parkinsons.
The best sources of folic acid are simultaneously some of the healthiest foods on the planet, namely dark green vegetables like broccoli, spinach, collard greens, brussels sprouts, asparagus and okra all of which can be grown in your backyard! This B vitamin can also be found in avocado, legumes and lentils.
Mri In Parkinson’s Testing
One of the more common tests done during a neurologic workup is an MRI scan and one may think that in the investigation of a disease that affects the brain such as Parkinsons, this imaging test would be a necessity. In the context of Parkinsons disease, however, an MRI is not particularly helpful. It looks at the structure of the brain which, for all intents and purposes, appears normal in this disease. An MRI may, however, be indicated when symptoms appear in younger people or if the clinical picture or the progression of symptoms is not typical for Parkinsons. In these situations, MRI can be used to rule out other disorders such as stroke, tumors, hydrocephalus , and Wilsons Disease .

How Parkinsons Disease Is Diagnosed
Diagnosing Parkinsons disease can be complicated because there isnt a specific blood test or screening test that can determine whether or not you have it.
Instead, Parkinsons is diagnosed clinically, which means a doctor will examine you, review your symptoms and medical history, and diagnose accordingly.
Parkinsons disease is a neurological condition that can make movement difficult. If your general practitioner thinks you might have Parkinsons, they may refer you to a neurologist who specializes in movement disorders for a diagnosis.
It can be challenging to catch Parkinsons in the early stages because the symptoms may be too mild to notice or meet the diagnostic criteria. Also, early Parkinsons symptoms are often mistaken for typical signs of aging.
The symptoms of Parkinsons disease are also similar to those of other health conditions, which may be misdiagnosed as Parkinsons at first. Your doctor may suggest specific tests and scans to help eliminate other conditions that can mimic the symptoms of Parkinsons disease.

What Is Parkinson’s Disease
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.
Parkinsons affects nearly 1 million people in the United States and more than 6 million people worldwide.

What Is Parkinson’s Disease?
Dr. Rachel Dolhun, a movement disorder specialist and vice president of medical communications at The Michael J. Fox Foundation, breaks down the basics of Parkinson’s.
Who Are More Likely To Develop Parkinson’s Disease
Parkinson’s disease affects both men and women, though about 50% more men are affected than women. The reasons for this are unclear but there are theories that estrogen may cause women to develop the disease less frequently, and when they do, they seem to get a milder form of it. The National Institute of Neurological Disorders and Stroke estimates about 50,000 people are diagnosed with PD each year in the U.S. However, this number may be higher due to the fact that many people in the early stages of PD assume their symptoms are due to aging and do not seek medical attention. Complicating the diagnosis is that symptoms of Parkinson’s resemble other diseases and there is no one definitive test to diagnose it.

What Are My Next Steps
If your doctor doesnt diagnose Parkinsons, they can help you find out what the best next step is depending on what condition they suspect. In some cases, treatment may be as simple as changing the dosage of a medication that may be leading to Parkinsons-like symptoms.
Receiving a Parkinsons diagnosis can be overwhelming. If your diagnosis is confirmed, contact a movement disorder specialist as soon as possible. A specialist can help you develop a strategy to delay the onset of more severe disease and manage symptoms youre already experiencing.
The Use Of Levodopa And Peripheral Neuropathy
There are reports in the literature that levodopa use may increase the risk of peripheral neuropathy, although other studies suggest that this is not the case. There are studies that demonstrate for example, that cumulative Levodopa exposure correlates to prevalence of PN in people with PD. Other studies however, demonstrate no difference in the prevalence of PN whether the person was treated with Levodopa or not, suggesting that Levodopa treatment does not play a role in development of PN.
Another area of research that emerges from the literature is the potential role of Vitamin B12 deficiency in the development of PN in those with PD. Some studies suggest that Vitamin B12 deficiency is a more common cause of PN among those with PD than those with PN who do not have PD.
There is also research that suggests that levodopa treatment may contribute to PN through impairment of Vitamin B12 metabolism, leading to Vitamin B12 deficiency. Taking COMT inhibitors such as Entacapone may protect against this complication.
Regardless, if PN is diagnosed in anyone, whether they have PD or not, and whether they take Levodopa or not, Vitamin B12 and various other markers of Vitamin B12 metabolism should be tested. If Vitamin B12 levels are low or even low-normal, a person should take Vitamin B12 supplementation, which may help with the symptoms of PN. Other causes of PN, many of which can be checked with various blood tests, should be investigated as well.
