In one study, 225 children with dyslexia aged 7–13 were treated with either 3.3 grams of piracetam or a placebo daily for 36 weeks. Research indicates that piracetam may help people with dyslexia learn and read better. Human studies on piracetam and cognition are dated, and newer studies are needed.ĭyslexia is a learning disorder, which makes it harder to learn, read, and spell. Summary Piracetam may improve mental performance, but its effects take time to appear. More recent studies are needed before it can be confidently recommended. That said, most human studies on piracetam and brain function are fairly dated. However, piracetam improved short-term mental performance in people post-surgery, compared to a placebo ( 13). Meanwhile, an analysis of three studies looked into the effects of piracetam on people undergoing coronary bypass surgery, a procedure that restores blood flow to the heart.īrain impairment can be a side effect of this surgery. In another 21-day study in 16 adults with dyslexia and 14 healthy students, taking 1.6 grams of piracetam daily improved verbal learning by 15% and 8.6%, respectively ( 11).Īdditional research in 18 healthy, older adults found that participants performed significantly better in a variety of learning tasks when taking 4,800 mg of piracetam per day, compared to when not supplementing with the drug ( 12). In one study in 16 healthy people, those taking 1,200 mg of piracetam daily performed better at verbal learning tasks than people in the placebo group after 14 days, though no differences in memory and cognition had been detected after 7 days ( 10). These are other factors that may improve brain function ( 5, 6, 7, 8, 9). Other studies observe that piracetam increases your brain’s blood supply, as well as oxygen and glucose consumption, especially in people with mental impairment. That could be a reason why its effects appear to be stronger in older adults and people with mental issues, as research shows that their cells membranes tend to be less fluid ( 4). This makes it easier for cells to send and receive signals, which aids communication ( 2, 3). Though it’s unclear why, animal studies provide potential reasons.įor example, animal studies indicate that piracetam makes cell membranes more fluid. Research suggests that taking piracetam may enhance brain function.
