Verbal Memory Dysfunction in Substance Use and Gambling Addictive Disorders: Comparative Analysis of Performance and Error Patterns
This study examined immediate and delayed verbal memory performance in 515 participants including those with stimulant, alcohol, cannabis use disorders and gambling disorder versus healthy controls. Findings revealed significantly lower recall accuracy in substance use and gambling disorders with distinct error profiles: alcohol use disorder showed elevated intrusion errors (inhibitory deficits), stimulant use showed increased repetition errors (monitoring deficits), while gambling disorder showed performance decline without elevated error patterns.
