Merriman NA, et al. - In this systematic review, researchers identified which types of (non-randomized) psychological interventions improve cognitive function post-stroke, and evaluated the effectiveness of these interventions in stroke survivors. Via a search of Pubmed, EMBASE, and PsycINFO databases, 20 eligible studies (7 controlled studies and 13 one-group pre-post studies) were identified. In all, the investigators noted an overall impact on cognition across the controlled studies and a moderate impact across the one-group pre-post studies. Specific cognitive domains (eg, memory and attention) also showed a psychological intervention benefit. This review supported the potential of psychological interventions to improve the overall post-stroke cognitive function.
