Longitudinal Evaluation of Working Memory in Duchenne Muscular Dystrophy.

ABSTRACT: Objective: The developmental maturation of forward and backward digit spans-indices of working memory-in boys with nonsense (nm) Duchenne muscular dystrophy (DMD) (nmDMD) was assessed using prospective, longitudinal data. Methods: Fifty-five boys of the 57 subjects with genetically confirmed nmDMD-who were from the placebo arm of a 48-week-long phase 2b clinical trial-were evaluated. Forward and backward digit spans were obtained every 12 weeks for a total of five assessments in all study subjects. Changes in forward and backward digit spans were evaluated based on age, corticosteroid treatment, and DMD mutation location. Results: Boys with nmDMD had lower mean scores on normalized forward digit span. Normalized forward digit spans were comparable between subjects stratified
