Objective:
To investigate neuropsychological functioning in adolescents with anorexia nervosa (AN) before and after receiving cognitive remediation therapy (CRT).
Method:
Twenty young females with AN participated in an individually-delivered CRT treatment program. Neuropsychological and psychiatric assessments were administered before and after treatment. Weight, depression, anxiety, duration of illness, and level of eating disorder psychopathology were considered as covariates in statistical analyses.
Results:
Significant changes in weight, depression, visio-spatial memory, perceptual disembedding abilities, and verbal fluency were observed. Changes in weight had a significant effect on improvements in visuo-spatial memory and verbal fluency. Results also revealed a significant effect of depressive symptoms on perceptual disembedding abilities.
Discussion:
The results suggest improvements on a number of neuropsychological functions during the course of CRT. Future studies should explore the use of additional assessment instruments, and include control groups to assess the effectiveness of the intervention.
