Abstract
After experiencing two ischemic brain attacks, a 40-year-old, right-handed, female amateur cello player developed apraxia of speech (AOS) and amusia, especially on the aspect of the beat. Her tempo became gradually faster, but while playing, she could not recognize that. When she listened to her own recorded performances, she could identify the differences immediately and precisely. Brain MRI showed lesions in the right superior temporal lobe, temporal plate, and right and left precentral gyri. Neuromusicological assessments revealed severe beat impairment and moderate pitch impairment. We diagnosed her with beat deafness of music, possibly caused by the bilateral precentral gyri lesions.
期刊介绍：
Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
