An Investigation on Cognitive and Behavioral Effects of Donepezil on Autistic Children in Winter 2020 in Gorgan's Taleghani Pediatric Hospital.

The present investigation has shown that all the studied variables, including irritability, lethargy, stereotypic behavior, hyperactivity, and inappropriate speech, were significantly decreased towards the desired goal by 46%. This significant decrease is indicative of the effectiveness of the treatment of autism patients with donepezil, and therefore, this drug can be placed as a prominent and essential part of the medical therapy of autism.
