Background:

Alcohol use disorder (AUD) is linked to significant cognitive and executive deficits.
Cognitive training offers potential for reversing some alcohol-related cognitive impairments.
Digital interventions like virtual reality (VR) are emerging but require more research.

Purpose of the Study:

To assess the feasibility of VR-based cognitive training for AUD patients in residential treatment.
To estimate the effect size of VR cognitive training on cognitive functions in AUD.
To inform future definitive randomized controlled trials (RCTs).

Main Methods:

A pilot two-arm RCT involving 36 individuals recovering from AUD.
Experimental group received VR cognitive training plus treatment as usual; control received treatment as usual.
Neuropsychological tests measured global cognition, executive functions, attention, visual memory, and cognitive flexibility pre- and post-intervention.

Main Results:

VR intervention showed positive effects on attention and cognitive flexibility.
Effect sizes were larger for attention improvements compared to cognitive flexibility.
High patient retention rates were observed for the VR cognitive training component.

Conclusions:

VR-based cognitive training is a feasible and potentially effective intervention for AUD.
The study provides evidence for VR's specific benefits in enhancing attention and cognitive flexibility in AUD recovery.
Results support the development of larger RCTs for VR interventions in AUD treatment.
