Coffee May Help Some Parkinson's Disease Movement Symptoms, Research Suggests

ScienceDaily (Aug. 1, 2012) — While drinking coffee with caffeine each day does not appear to reduce sleepiness among people with Parkinson's disease, it may have a benefit in controlling movement, according to new research published in the August 1, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

• For the study, 61 people with Parkinson's disease who showed symptoms of daytime sleepiness and some motor symptoms were given either a placebo pill or a pill with 100 milligrams of caffeine two times a day for three weeks, then 200 milligrams twice a day for three weeks, which was the equivalent of between two and four cups of coffee per day. 
• After six weeks, the half that took the caffeine supplements averaged a five-point improvement in Parkinson's severity ratings compared to those who didn't consume caffeine. 
• The study authors noted that the length of the study was short and that the effects of caffeine may lessen over time

帕金森氏症（英语：Parkinson's Disease），或譯巴金森氏病，中国大陆譯作帕金森病，台湾譯作帕金森氏症， 港澳譯作柏金遜症，是一種慢性的中樞神經系統退化性失調，它會損害患者的动作技能、語言能力以及其他功能。它的病因目前仍不明，推測和大腦底部基底核（basal ganglia）以及黑質（substantial nigra）腦細胞快速退化，無法製造足夠的神經引導物質多巴胺（Dopamine）和膽鹼作用增強有關。腦內需要多巴胺來指揮肌肉的活動；缺乏足夠的多巴胺就產生各種活動障礙。
