THE PREVALENCE OF NON-MOTOR SYMPTOMS IN PARKINSON'S DISEASE
Clinical Neurology and Neurosurgery  Aug 16
[Epub ahead of print] (E.M.Khedr, N.A.El Fetoh, H.Khalifa, M.A.Ahmed, K.M.El Beh)
The non-motor symptoms that were found to most prevalent in Parkinson's Disease were : disturbance of mood and cognition (87%), sleep disturbance and fatigue (78%), gastrointestinal (76%), urinary (76%), sexual dysfunction (73%), cardiovascular (70%). Perceptual problems and hallucinations are infrequent (10%) and are usually due to Parkinson's Disease drugs, especially dopamine agonists, rather than Parkinson's Disease itself. Dementia, which was found to be mostly mild, occurred in around 22% of people with Parkinson's Disease. Although dementia often eventually occurs in Parkinson's Disease, it has an entirely different biochemistry from Parkinson's Disease. It is therefore not a Parkinson's Disease symptom or inevitable in Parkinson's Disease. For a printable version of this article click here. In order to refer to this article on its own click here.

DIAGNOSIS OF PARKINSON'S DISEASE USING SPEECH
IEEE Transactions on Biomedical Engineering 
59 (5) : 1264-1271 (A.Tsanas, M.A.Little, P.E.McSharry, J. Spielman, L.O.Ramig)
Researchers assessed how accurately such measures can be in discriminating people with Parkinson's Disease from people who do not have it. In total, the researchers computed 132 measures of dysphonia measures from sustained vowels. They then used a large database of vocal samples from different people. The researchers demonstrated that these measures of dysphonia can outperform standard methods of diagnosing Parkinson's Disease by reaching almost 99% overall classification accuracy. They achieved this by using only ten features of dysphonia. For a printable version of this article click here. In order to refer to this article on its own click here.

PARKINSON'S DISEASE IS PREVALENT AMONG NATIVE AMERICANS
Movement Disorders  Aug 14 [Epub ahead of
print] (P.H.Gordon, J.M.Mehal, R.C.Holman, A.S.Rowland, J.E.Cheek)
The age adjusted prevalence of Parkinson's Disease was found to be 355 people per 100,000. This makes it the highest in North America, even beyond the 329 per 100,000 found in Nebraska, which was previously thought to have the highest prevalence of Parkinson's Disease in North America. The prevalence amongst Native Americans increased with age up until 84 years old, and was greater amongst men rather than women.

CAFFEINE REDUCES PARKINSON'S DISEASE

Caffeine was found to reduce Parkinson's Disease symptom scores using the standard scale for Parkinson's Disease, which is the UPDRS. There were no changes in quality of life, depression or sleep quality. The amount of coffee assessed was 2 to 4 cups of coffee per day. The trial lasted for 6 weeks. Caffeine is commonly found in coffee, and to a lesser extent in tea, cola drinks, cocoa, and chocolate. Studies had consistently linked caffeine, a non-selective adenosine antagonist, to a lower risk of Parkinson's Disease. However, the effects on the symptoms of people who already had Parkinson's Disease had not previously been adequately evaluated.
The researcher described it as "a modest improvement, but may be enough to provide benefit to patients". He pointed out that the study was short and that the effects of caffeine may lessen over time. Previous studies that used much higher quantities (about 8 cups of coffee per day) resulted in no improvement in symptoms, and instead caused an increase in dyskinesia, restlessness and insomnia.
