In a randomized, double-blind, placebo-controlled trial, 50 subjects with memory impairment, early dementia, or a low score on a general cognitive function test took either placebo or 600 mg of an ashwagandha root extract for 8 weeks.
The primary outcome was considered to be performance on various cognitive tests, including memory, visuospatial processing, executive function, and attention. At the end of 8 weeks, participants taking ashwagandha saw statistically significant improvements compared with the placebo group in most memory tests, executive function, and attention, though not visuospatial processing.
