Summary

This study tested a safe, noninvasive treatment for memory and word-finding problems in Gulf War veterans. 93 veterans received either real or fake (sham) brain stimulation over 10 sessions. The goal was to see if the stimulation improved their ability to recall words and speak more fluently. If effective, this simple treatment could be used widely in VA clinics.
