Piracetam For Alzheimer's Disease
    Piracetam is a popular remedy for dementia in Europe. One
survey found that piracetam is the most common drug prescribed by German doctors
for senile dementia [160]. Piracetam increases glucose use by the brain and has
general cognitive-enhancing effects even in non-demented
people.
Piracetam is not generally effective in alzheimer
patients. A review by the Cochrane Database System Review summarized the results
of all clinical studies that used piracetam to treat alzheimer patients[161]. In
most studies, the dose given has ranged from 2.4 to 9.9 grams of piracetam
daily. There are no significant side effects to the drug. Although piracetam
does not seem to enhance cognitive abilities in patients, it does increase
alertness [162].
