Narrative review synthesizing preclinical animal models and qualitative clinical literature.
PubMed 31778722 · doi:10.1016/j.pbb.2019.172829
What was done
Narrative review surveying preclinical animal studies and clinical literature evaluating environmental enrichment as an intervention for substance use disorders, as well as associated neuroplastic mechanisms in the mesocorticolimbic system.
What was found
The abstract provides no quantitative metrics or effect sizes. Preclinical findings report that environmental enrichment introduced after drug exposure reduces compulsive drug-taking, diminishes drug reward and reinforcement, decreases behavioral control by drug cues, and prevents relapse. Clinical literature suggests multidimensional enrichment (encompassing physical activity, social interaction, vocational training, and community involvement) may offer similar benefits if delivered continuously and rigorously.
Why it matters
Synthesizes behavioral and neurobiological evidence supporting environmental enrichment as a non-pharmacological strategy to reduce craving and prevent relapse in substance use disorders.
Limits
The abstract contains no numerical data, study counts, or systematic review methodology. Much of the presented evidence derives from preclinical animal models, and the clinical efficacy, optimal protocols, and feasibility of continuous multidimensional enrichment in human populations are not quantified.
