Research evidence for cognitive remediation therapy's (CRT) effectiveness for anorexia nervosa (AN) has been gathering. This approach is also increasingly being implemented in other disorders including major depressive disorder, obsessive-compulsive disorder and autistic spectrum disorder that share commonalities with AN in neuropsychological profiles and clinical presentations. This systematic literature review identified and appraised the current evidence base to see whether evidence from related conditions could be integrated into the theoretical understanding of CRT for AN as well as future AN treatment developments and research. Overall, CRT studies in AN report promising findings, and CRT appears to be associated with improvements in set-shifting and in central coherence. Cognitive remediation approaches in other conditions also show promising evidence in associated improvements in areas of executive functioning and information processing; links are made between AN treatment and what future treatment developments could consider.
