Cognitive training shows benefits for improving memory and executive functions in individuals with substance use disorder (SUD). This approach aids in recovery by enhancing cognitive abilities compromised by addiction.
Area of Science:
- Neuroscience
- Psychology
- Addiction Medicine
Background:
- Substance abuse significantly impairs cerebral neuroplasticity, affecting memory and executive functions.
- Cognitive deficits are linked to poorer treatment outcomes in substance dependence.
- Cognitive training offers a promising avenue for improving cognitive functions and aiding addiction treatment.
Approach:
- Systematic review of randomized clinical and quasi-experimental studies.
- Searched four databases (PubMed, Cochrane Library, Web of Science, PsycINFO) from 1985-2019.
- Assessed study quality and risk of bias using established tools.
Key Points:
- 26 studies were eligible for evaluation, covering various substance use disorders.
- 18 studies reported cognitive improvements, with memory being the most frequently targeted and affected function.
- Improvements were observed in memory, executive functioning, and processing speed.
Conclusions:
- Cognitive training is effective in enhancing cognitive functions for individuals with substance use disorder.
- Memory and executive functions, often impaired by substance use, show benefits from cognitive interventions.
- This review synthesizes evidence supporting cognitive training as a valuable component in addiction recovery programs.
