Piracetam reverses the effects of aging in the brain. Piracetam also appears to be effective in treating cognitive impairment in alcoholism. Piracetam is useful as a long-term treatment for clotting, coagulation, and vasospastic disorders such as deep-vein thrombosis as it operates through the novel mechanism of inhibiting platelet aggregation and enhances blood-cell deformability. Some research suggests that piracetam’s overall effect on lowering depression and anxiety is even higher than memory improvement. Piracetam has become a popular supplement in the subculture of lucid dreaming. Its use has been largely made popular by a book published by Thomas Yuschak titled Advanced Lucid Dreaming The Power of Supplements. A daily dose of 4.8 grams is considered optimal.
