Abstract
A double-blind, placebo-controlled trial was carried out on 109 aged patients with minimal or with moderate chronic brain failure to assess the effectiveness of piracetam (2.4 g per day) in preventing the progression of dementia. Patients received piracetam or placebo each for 6 weeks, the order of treatment being at random. The results of 19 psychological tests, repeated at 6-weekly intervals, showed that piracetam produced statistically significant improvement in only one of them and then only during the first 6 weeks of treatment. These findings, therefore, do not support the usefulness of piracetam in the treatment of such patients.
