Abstract

We studied the relationship between musical and cognitive deficits by testing middle cerebral arterial (MCA) stroke patients (n= 53) with a shortened version of the Montreal Battery of Evaluation of Amusia (MBEA) and an extensive neuropsychological test battery. Results showed that amusic patients (n= 32) had more severe cognitive deficits, especially in working memory and executive functioning, than did non-amusic patients (n= 21), and the severity of amusia also correlated with attention deficits. These findings thus suggest that domain-general attention, executive, and working memory processes are associated with amusia after stroke.
