Dietary Tryptophan Reverses Alcohol‐induced Impairment of Facial Recognition But Not Verbal Recall

Abstract
The present study demonstrates that alcohol-induced memory impairment can be attenuated by pretreatment with an oral tryptophan supplementation. These results provide support for the role of a brain serotonin deficit in this impairment and highlight the impact a dietary manipulation can have on a complex behavioral process.
