Alzheimer’s, Parkinson’s and Dementia
A study revealed that people over the age of 65 with blood caffeine levels higher than those who did not drink coffee, did not develop Alzheimer’s disease for two to four years later than the other non-coffee drinkers.
"We are not saying that moderate coffee consumption will completely protect people from Alzheimer's disease. However, we firmly believe that moderate coffee consumption can appreciably reduce your risk of Alzheimer's or delay its onset," said Dr. Chuanhai Cao, neuroscientist at University of South Florida and co-author of the study.
One Swedish and Finnish study showed that people who drank three to five cups of coffee a day for 20 years were 65 percent less likely to develop dementia and Alzheimer’s disease.
“For Parkinson’s disease, the data have always been very consistent: higher consumption of coffee is associated with decreased risk of Parkinson’s,” Hu said. That seems to be due to caffeine, though exactly how that works isn't clear, Hu notes.
Coffee could lessen the symptoms of Parkinson’s disease. Coffee is known to lessen the chances of developing Parkinson’s disease, but there is one study that demonstrates how coffee helps sufferers control their movements.
Suicide and Coffee Consumption
Those who drank 4 or more cups of coffee a day were ten percent less likely to suffer from depression. The proposed reason as to why -- coffee’s high level of anti-oxidants.
