Higher caffeine consumption has been associated with a reduced risk of Parkinson's Disease.
Besides coffee, caffeine also occurs to a lesser extent in tea, yerba mate, cola drinks, cocoa,
and chocolate.
The present study assessed people who were newly
diagnosed with Parkinson's Disease over the following
four years. Hgher caffeine consumption in people with
Parkinson's Disease was associated with a lower rate of
starting L-dopa treatment, down to 63% of normal.
Each
additional cup of espresso per day (50 mg of caffeine)
was associated with a 5-point lower score on the UPDRS
part III (motor symptoms), with a 50% reduction in
L-dopa dosage, but was not associated with a lower score
on the UPDRS part IV (therapy complications).
