DMD patients display a varying degree of memory impairments, which have been attributed to the loss of dystrophin in brain structures involved in cognition, including the cerebellum and hippocampus, with approximately one-third of patients displaying some degree of cognitive deficit frequently manifesting itself in memory impairment, but ranging from reduced verbal intelligence [10,12] to severe autism [13,14]. This evidence concerns the gene DMD and Duchenne muscular dystrophy.
