Rem Sleep Behavior Disorder
In vivid dreaming states most peoples bodies are still. However people with RBD lack muscle paralysis resulting in their acting out their dreams. This can include talking, screaming, shouting, hitting, punching or kicking, even propelling them out of bed. This can be scary and dangerous if they strike their partners or other bedside objects involuntarily. RBD is common in and can begin long before the onset of declining motor function. Fortunately it is also a very treatable condition.

What Type Of Stroke Causes Ataxia
Understanding Ataxia in Stroke Patients: A Cerebellar Stroke Effect. When a stroke affects the cerebellum, it can result in a secondary effect known as ataxia. Ataxia involves a lack of coordination and muscle control due to neurological dysfunction. This means the nervous system struggles to coordinated movement.
What Causes Ataxic Gait
Ataxic gait can be caused by abnormalities within the brain, spinal cord, and peripheral nervous system. When caused by issues with the cerebellum, gait deviations resulting from ataxia have distinct features. Holmes has defined cerebellar ataxia as a combination of dysmetria, dyssynergia, dysdiadochokinesia, dysrhythmia, and intention tremor.
The cerebellum sends signals throughout the brain that regulate fine motor movement. When cerebellar neurons are damaged, the cerebellum has difficulty integrating information from the rest of the body and brain. As a result, coordinating balance, posture, and smooth muscle activity are difficult, clearly impacting gait function.
Cerebellar disorders can be caused by hereditary ataxias, such as Friedrich Ataxia, and acquired conditions like Multiple Sclerosis, cerebellar strokes, traumatic brain injury, and long-term alcoholism. The similarity of ataxia to inebriation is no coincidence, as alcohol disrupts the main nerve cells in the cerebellum.

Assessment Of Type 2 Diabetes At Baseline
Assessment of the history of type 2 diabetes was based on self-reporting and on the data of two nationwide registers. The National Hospital Discharge Register data included hospital discharge diagnoses since 1968. Data on diabetes medication were ascertained from the national Social Insurance Institution’s register on special reimbursement for antidiabetic drugs from 1964. Antidiabetic drugs prescribed by a physician are free of charge in Finland and are subject to approval of a physician of the Institution who reviews each case history. The physician confirms the diagnosis of diabetes, applying the World Health Organization criteria: one or more classic symptoms plus a fasting plasma glucose level 7.8 mmol/l or the oral glucose tolerance test 11.1 mmol/l; at least one raised plasma glucose concentration on a fasting plasma glucose level 7.8 mmol/l or the oral glucose tolerance test 11.1 mmol/l in the absence of symptoms; or treatment with a hypoglycemic drug . All patients receiving free medication were entered into a register maintained by the Social Insurance Institution. Subjects who reported having diabetes on the questionnaire, or who had a hospital discharge with a diagnosis of diabetes, or the approval for free-of-charge medication for diabetes before the baseline survey, were classified as having the history of diabetes at baseline.

What Research Is Being Done
The mission of the National Institute of Neurological Disorders and Stroke is to seek knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world.
NINDS-funded research ranges from clinical studies of the genetics and the natural history of hereditary neuropathies to discoveries of new cause and treatments for neuropathy, to basic science investigations of the biological mechanisms responsible for chronic neuropathic pain. Together, these diverse research areas will advance the development of new therapeutic and preventive strategies for peripheral neuropathies. Understanding the causes of neuropathy provides the foundation for finding effective prevention and treatment strategies.
NINDS-supported researchers are also exploring the use of tissue engineered from the cells of humans with peripheral neuropathy as models to identify specific defects in the transport of cellular components along axons and the interactions of nerves with muscles. Such tissue engineering approaches may eventually lead to new therapeutics for peripheral neuropathies.
What Is The Outlook For People With Ataxia
The outlook for people with ataxia varies greatly depending on the type and underlying cause. Most people with ataxia have symptoms that get worse with each year. Treatment is necessary to control symptoms and improve quality of life.
In other people, doctors can treat the underlying cause of ataxia with medication. With effective treatment, their symptoms may stay the same or even improve over time. There is ongoing research to find a cure for ataxia.

Treatment Of Rls In Pd
Regardless of the above discussion, it is clear that many people with PD have difficulty falling asleep because of annoying sensations in the legs accompanied by a sometimes unbearable sense of restlessness in the legs. For these people, taking dopamine agonists before bed can be helpful. Caution is in order, of course, because in some patients with PD, especially older or more advanced patients, these medications can cause confusion and hallucinations and are thus not well-tolerated. A long-acting levodopa formulation or medications such as gabapentin, gabapentin enacarbil and pregabalin can also be effective. Trying to address sleep issues such as RLS in patients who have sleep complaints can be an important aspect of maximizing therapy for PD.

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.

Risk Factor Assessment For Large And Small Fiber Neuropathy
Patients with EMG abnormalities were older: 65.5±3.8 vs. 53±3;years , but abnormalities on SWT scores were not associated with age. In addition, patients with either SWT or EMG abnormalities were not more likely to be older than normal patients. Patients with EMG abnormalities were more likely to be older at the disease onset but there was no significant relationship between EMG abnormalities and disease duration. In addition, there wasnt any significant relationship between the age of disease onset or disease duration and SWT scores .
Regression analysis of tibial and peroneal CMAP amplitudes and conduction velocities or sural SNAP and conduction velocities versus the presence of DM or B12 levels was not significant. In addition, regression analysis also did not disclose any significant relationship between SWT scores and electrodiagnostic parameters, i.e. tibial and peroneal CMAP amplitudes and conduction velocities or between sural SNAP and conduction velocities.
General Assessment Of Peripheral Neuropathy
Peripheral neuropathy, as compared with IPD, can be due to hundreds of different etiologies , and is associated with a variety of pathological changes within a peripheral nerve. The most common causes of peripheral neuropathy are metabolic or endocrine disorders such as with diabetes mellitus, uremia, or thyroid disease, infections such as with human immunodeficiency virus or leprosy, toxic effects as with chemotherapy or alcohol excess, genetic disorders such as with Charcot-Marie-Tooth disease, amongst other causes. Another potentially underdiagnosed cause of peripheral neuropathy is a nutritional deficiency such as with insufficient vitamin B1, vitamin B6, vitamin B12, folate or thiamine . Many other causes of peripheral neuropathy occur, but between 40-50% of patients with peripheral neuropathy have no determined cause for their peripheral neuropathy, leading to its designation as an idiopathic peripheral neuropathy . Typically, idiopathic peripheral neuropathy occurs in older patients and has a slow progression over many years, but its overall clinical presentation and course of progression is similar when compared with other forms of peripheral neuropathy. There are likely a number of causes of idiopathic peripheral neuropathy, many of which may be due to neurodegenerative conditions which have not yet been determined.

What Is Polyneuropathy
Polyneuropathy is a neurologic illness. It affects the peripheral nerves. That means that it is an illness that affects the nerves in the arms and legs, and not the nerve cells in the brain. In most people, the feet are affected before the hands. Most polyneuropathies occur slowly and gradually. At first, they may cause no symptoms. The person is unaware that a problem is happening until it becomes more severe. At this point, the person may develop numbness or tingling in the feet and hands. Later, the tingling may become more painful, feeling like a burning sensation. In some people, weakness also occurs.
There are many different kinds of neuropathies. There are many different causes such as autoimmune reactions, toxins, certain drugs, and cancer. The most common causes are diabetes mellitus or the excessive use of alcohol. Less common causes like nutritional deficiencies and liver or kidney failure may cause a polyneuropathy.
Once the cause of the polyneuropathy has been found, the treatment is directed to the cause. Medications to treat the burning sensation may also be needed. There are several medications that can help, and the doctor will help to select the best one for the person with the polyneuropathy.
How Are They Alike
These diseases both affect your nerves. MS can break down the coating, called myelin, that surrounds and protects your nerves. In Parkinsonâs, nerve cells in a part of your brain slowly die off.
Both can start out with mild symptoms, but they get worse over time.
Common symptoms of both diseases include:
- Shaky fingers, hands, lips, or limbs
- Slurred speech thatâs hard for others to understand
- Numb or weak limbs that make your walk unsteady
- Loss of muscle control that often affects one side of your body at first, then later both
- Spastic limb movements that are hard to control
- Loss of bladder or bowel control
- Poor balance

Clinical Management Of Ldopainduced Pnp
A strong level of evidence supports a role, at least partial, for vitamins of the group B and related cofactors in the pathogenesis of ldoparelated PNP. Monitoring the plasma levels of vitB6, vitB12, MMA, and Hcy is of utmost importance in patients starting and continuing LCIG therapy, as well as in patients with high oral ldopa intake or at higher risk of PNP . Some researchers suggested a periodic clinical, electrophysiological, and biochemical assessment in patients undergoing LCIG. A basic screening should include regular monitoring of vitB12 and folate since the beginning of the treatment, plus a determination of Hcy and MMA in cases of borderline vitamin levels. Vitamin supplementation should be started in all patients showing biochemical alterations or symptoms of PNP., Other empirical approaches include a prophylactic supplementation with high doses of vitB12 and folate since the beginning of LCIG. Rispoli and colleagues found a very low incidence of subclinical PNP in 30 patients undergoing supramaximal supplementation with vitB12, folic acid, vitB6, and vitB2 since the early onset of LCIG treatment. Although extensive vitB6 supplementation is scarcely recommended because of the interference with decarboxylase inhibitor and the potential neurotoxic effect of pyridoxine megadoses, preliminary evidence suggests that COMT inhibitors might be beneficial to prevent the development of PNP in patients receiving ldopa treatment.

Research Design And Methods
Six independent cross-sectional population surveys were carried out in five geographic areas of Finland in 1972, 1977, 1982, 1987, 1992, and 1997 . In 1972 and 1977, a randomly selected sample making up 6.6% of the population born between 1913 and 1947 was drawn. Since 1982, the sample was stratified by area, sex, and 10-year age-group according to the World Health Organization MONICA protocol . The subjects included in the six surveys were 2564 years of age, and the 1997 survey also included subjects aged 6574 years. Subjects who participated in more than one survey were included only in the first survey cohort. The total sample size of the six surveys was 53,166. The participation rate varied by year from 74 to 88% . After excluding 123 subjects because of prevalent Parkinsons disease at baseline, 112 subjects because of prevalent type 1 diabetes at baseline or during follow-up, and 1,379 subjects because of incomplete data on any variables required, the present analyses comprise 25,168 men and 26,384 women. The participants gave informed consent . These surveys were conducted according to the ethical rules of the National Public Health Institute, and the investigations were performed in accordance with the Declaration of Helsinki.
Definite Vs Probable Vs Possible Fxtas
- Individuals with one major clinical symptom and one major radiological symptom .
- Any individual with the presence of FXTAS inclusions based on neuropathology.
- Individuals with two major clinical symptoms .
- Individuals with one minor clinical symptom and one major radiological symptom .
- Individuals with one major clinical symptom and one minor radiological symptom .
- Any individual who may be a Fragile X carrier or who has symptoms in any of these three categories should be seen by a neurologist, movement disorders specialist, or psychiatrist familiar with FXTAS or the other Fragile X conditions.
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.
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.
