Neuropathy And Parkinson’s Disease

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.

Nerve Conduction Studies Hrus And Diagnosis Criteria Of Pnp

All patients underwent electrophysiological examination performed by a board-certified neurologist with the use of a Medtronic four channel electroneurography device . Motor studies of tibial and median nerve as well as sensory studies of sural and median nerve were done bilaterally maintaining skin temperature at 36°C and were referenced to normal values. Nerve HRUS examination was performed with an Affinity®70G ultrasound system with an 18-MHz linear array transducer as described previously. It was performed bilaterally at entrapment and nonentrapment sites. The entrapment sites included the median nerve , the ulnar nerve , and fibular nerve . The nonentrapment sites contained the median nerve , the ulnar nerve , and the fibular nerve . In order to avert anisotropy, the transducer was kept perpendicular to the nerves and no additional force was applied while the extremities were kept in neutral position to avoid nerve deformation. The measurement of CSA was performed at the inner border of the thin hyperechoic epineural rim by a continuous tracing technique.

The diagnosis criteria for PNP were determined by nerve conduction studies. The lower value of bilateral conduction was regarded to detect early PNP. In order to include and analyze neuropathy groups with different severity in NCS we defined three PNP subgroups based on normal values .

Patients With Parkinsons Disease Are At Risk For Carpal Tunnel Syndrome

Patients with carpal tunnel syndrome experience pain, numbness and tingling that can be characterized as an upper limb neuropathy. CTS is more common in women, with a female to male ratio of 3:1. Various studies have described the incidence of CTS in the general population as between 2.5 and 5 cases per 1,000 person years. Approximately one-third of patients newly diagnosed with CTS receive operative treatment, and this percentage appears to be increasing.1 Although surgery is known to be an effective treatment, the question remains: Which patients are the best candidates for surgery?

Individuals with Parkinsons disease may be especially vulnerable to CTS. One study suggests that patients with Parkinsons may be at increased risk of CTS because of the repetitive movement due to tremor.2Others have noted the peripheral neuropathy that is associated with Parkinsons and wondered whether peripheral neuropathy is intrinsic to Parkinsons, a consequence of levodopa exposure or both.3 A body of evidence suggests that a form of small fiber neuropathy is intrinsic to Parkinsons, and thus, experts have suggested that patients with early and advanced Parkinsons be strictly monitored for subtle signs of neuropathy. Such evaluation should make it possible for healthcare providers to detect early symptoms of peripheral neuropathy and potentially provide better management.

What is Neuropathy?

Common Misdiagnosis: Peripheral Neuropathy

Peripheral neuropathy occurs when the nerves outside of the brain and spinal cord are damaged. Muscle contractions are a common physical symptom. In contrast, PD has a variety of physical, mental, and emotional symptoms.

My husband started tremors 14 years ago but was only diagnosed last year. The doctor had previously said it was peripheral neuropathy.

My old neurologist for 11 years said peripheral neuropathy! VA then said 50/50 Parkinsons and sent me to the CU Movement Disorder Center. My new neurologist watched me walk along with other tests and said Parkinsons.

Corneal And Intraepidermal Nerve Fibers

Twenty-six PD patients and 26 controls underwent CCM and 24 PD patients and 10 controls underwent skin biopsies. Both CNFD and IENFD were significantly lower in PD patients compared to controls . However, CNBD was significantly higher in PD patients compared to controls , P< 0.001). CNFL was also significantly higher in PD patients .

Parkinsons Disease And Alcohol: Your Guide

If you have Parkinsons disease , you may be wondering whether alcohol consumption affects the development or progression of your condition. Some people may wonder if they should avoid drinking completely. As one MyParkinsonsTeam member asked, How does alcohol affect Parkinsons how much can I drink? Or should I avoid drinking altogether?

Some studies havent found that small amounts of alcohol are associated with a higher PD risk, while others highlight the dangers alcohol can pose for anyone with a chronic condition. In addition, there may be adverse interactions between alcohol and common Parkinsons medications. Because of conflicting information, people with PD may feel confused about whether or not to drink.

Ive been told by more than one doctor that I should not have any alcohol, one MyParkinsonsTeam member wrote. And at this point, I dont remember which doctor or specifically why.

So, how do you decide what approach to take?

If you have Parkinsons disease and are trying to decide whether or not to reduce your drinking or quit alcohol completely here are some things to consider.

What Are The Causes

The cause of Parkinsons is largely unknown. Scientists are currently investigating the role that genetics, environmental factors, and the natural process of aging have on cell death and PD.

There are also secondary forms of PD that are caused by medications such as haloperidol , reserpine , and metoclopramide .

Ways To Decrease Risk Of Heart Disease

As in the general population, heart disease in people with PD can be decreased by managing traditional risk factors:

• Smoking cessation According to the American Heart Association, smoking is the most preventable cause of premature death in the U.S. Smoking increases the risk of developing many chronic disorders, including atherosclerosis that can lead to heart disease and stroke.3
• Treatment of high blood pressure Approximately 90% of all Americans will develop hypertension, or high blood pressure, over their lifetime. Hypertension puts more stress on arteries and can cause damage over time.3
• Treatment of high cholesterol High cholesterol is one of the major controllable risk factor for heart disease. When too much LDL cholesterol is in the blood, it can build up in the artery walls and narrow the vessels that feed the heart and brain.3
• Control of diabetesDiabetes can affect many major organs in the body, including the heart. Fortunately, diabetes is treatable and often preventable.3

Clinical And Demographic Data Of Pnp Subgroups

Fifty PD patients were included into the analysis with a mean disease duration of 6.5 ± 5.1 years, mean levodopa dosage of 590 ± 391, and mean MDS-UPDRS III of 31.2 ± 16.6. Of the 50 patients, 31 patients fulfilled the electrodiagnostic criteria for PNP. Fourteen patients had a mild, sensory PNP, 11 patients had a moderate, sensorimotor PNP. Six patients had a severe, sensorimotor PNP.

Importantly, concerning PNP subgroups, there were no statistically significant differences between sexes, age of onset or for LED observed .

A Constipation In Stroke

Constipation and stroke seems associated, yet no studies have been able to show a direct association either clinically or pathophysiologically. However, the number of studies in this field is limited. It is a general experience, that constipation is frequent in acute admitted stroke patients. There may be several explanations for this: the patients are elderly, often treated with a number of drugs, dehydrated, and immobile already at admittance. Box 1 lists a number of drugs, which themselves or in combination may induce constipation. Bed rest and immobility often give rise to constipation, and may in addition induce deconditioning, resulting in inadequate force to defecate.

Hypovolemia is a common problem, both before and after stroke, the latter as a result of dysphagia and/or impaired thirst mechanisms and lack of attention to drinking possibilities. Diet may be another problem, as the hemiplegic population often has an insufficient intake of dietary fibre.

Lesions affecting the pontine defecatory centre may disrupt the sequencing of sympatical and parasympathical components of defecation, and impair the coordination of the peristaltic wave and the relaxation of the pelvic floor and external sphincter.

Tackling Neuropathy Fatigue And Gi Issues In Pd

While its known as a movement disorder, people who live with Parkinsons disease experience many non-movement, or non-motor, symptoms too though not all of them are related to the disease. Peripheral neuropathy, or nervous system damage, fatigue and GI issues are common PD challenges that can also stem from other causes. Working with your doctor to identify the source of your symptoms is key to effective treatment.

This article is based on the Parkinsons Foundation Expert Briefing series Symptom Management: Is it PD, Medication or Aging? Exploring Non-motor Symptoms: Neuropathy, Fatigue, GI Issues presented by Ellen Walter, Nurse Practitioner, Cleveland Clinic, and Steven Swank, Clinical Pharmacist, University of Kansas Medical Center. Both organizations are Parkinsons Foundation Centers of Excellence.

Causes of neuropathy, fatigue and impaired gastrointestinal function during the course of PD can be wide-ranging and include everything from normal aging to medication side effects.

With any health challenge, its recommended to log symptoms. This can help your doctor rule out potential causes. When did symptoms start? Are there any patterns?

Other Causes Of Parkinsonism

Parkinsonism is the umbrella term used to describe the symptoms of tremors, muscle rigidity and slowness of movement.

Parkinsons disease is the most common type of parkinsonism, but there are also some rarer types where a specific cause can be identified.

These include parkinsonism caused by:

• medication where symptoms develop after taking certain medications, such as some types of antipsychotic medication, and usually improve once the medication is stopped
• other progressive brain conditions such as progressive supranuclear palsy, multiple systems atrophy and corticobasal degeneration
• cerebrovascular disease where a series of small strokes cause several parts of the brain to die

Potential Pathogenic Mechanisms Of Peripheral Neuropathy In Idiopathic Parkinsons Disease Patients

The studies to date have been descriptive and associative in nature only. The precise pathogenic mechanisms for the development of peripheral neuropathy in IPD patients remain speculative. Before considering the mechanisms by which methylmalonic acid and/or homocysteine may be pathogenic, other considerations require discussion.

As mentioned, considerations for genetic influences are important. The potential implications of parkin mutations given the expression of parkin mRNA in peripheral nerve may be of importance, but only a small percentage of IPD patients with parkin mutations appear to have an axonal form of peripheral neuropathy . The relationship of concurrent peripheral neuropathy to the so called Parkinsons Plus forms of disease, such as with multiple system atrophy must also be considered patients with multiple system atrophy frequently have an axonal peripheral neuropathy present . Associations such as this may suggest a neurodegenerative pathogenesis for peripheral neuropathy rather than a deficiency. Indeed, patients with greater severity and longer duration of IPD were more susceptible to development of peripheral neuropathy in our studies as well . Further studies will be required to determine if the peripheral neuropathy present in IPD patients develops in an analagous fashion to the central nervous system neurodegeneration in IPD.

How Was The Study Done

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.

Clinical And Demographic Features

Table compares the demographic characteristics of the 38 patients with PD and 16 patients with other forms of parkinsonism that completed our work-up. Patients with PD were older than patients with parkinsonism . However, age of onset, disease duration and gender distribution were similar in both groups, despite a trend for higher percentage of women in the parkinsonism group and for older age of onset and longer disease course in the PD group. Mean Hoehn and Yahr scores in the PD group were 2.6±0.1 . Most of the PD patients were treated with levodopa and 68.8 % of the parkinsonism group were taking levodopa. A third of the PD patients and 31 % of the parkinsonism group were treated with pramipexol while 38.9 % of the PD and none from the parkinsonism group were treated with amantadine and only 8.3 and 18.8 were treated with biperiden.

Abstract

The study was approved by NRES committee/North West .

Thirty-three patients fulfilling the UK Brain Bank criteria for the diagnosis of Parkinsons disease were recruited from neurology clinics. Ten patients were excluded after screening for other causes of peripheral neuropathy . Unified Parkinsons disease Rating Scale-III was used to determine the more affected and the less affected side. Specifically, parts 38 and parts 1517 were compared.
