Cognitive Function as a Transdiagnostic Treatment Target in Stimulant Use Disorders

Area of Science:

• Neuroscience
• Psychiatry
• Public Health

Background:

• Stimulant use disorder (SUD) affects millions, with limited FDA-approved treatments.
• High rates of psychiatric comorbidities (mood, anxiety, psychosis) and cognitive impairments are prevalent in SUD.
• Existing behavioral treatments for SUD have variable efficacy and limited accessibility.

Purpose of the Study:

• To establish the rationale for targeting cognitive function in SUD treatment.
• To outline potential therapeutic strategies focused on cognitive enhancement.
• To explore cognition as a transdiagnostic treatment target for SUD and comorbid conditions.

Main Methods:

• Review of addiction models, particularly the dual process model, to understand cognitive relevance.
• Identification of specific cognitive impairments (attentional bias, working memory) linked to SUD.
• Exploration of pharmacological, cognitive, and behavioral interventions targeting cognitive functions.

Main Results:

• Cognitive impairments, such as attentional and approach biases, are linked to automatic processes in addiction.
• Executive control deficits (sustained attention, inhibition, working memory) are also common in SUD.
• These cognitive issues correlate with poor treatment outcomes and are frequently observed in comorbid psychiatric disorders.

Conclusions:

• Cognitive impairments represent a viable transdiagnostic treatment target for SUD.
• Pharmacotherapies (e.g., cholinesterase inhibitors) and cognitive interventions show promise for enhancing executive control.
• Cognitive bias modification and rehabilitation strategies may address automatic process deficits, but further research is needed to confirm clinical utility in SUD.
