A protective effect of musical expertise on cognitive outcome following brain damage?

The current review examines the possibility that training-related changes that take place in the brains of musicians may have a beneficial effect on their cognitive outcome and recovery following neurological damage. First, we propose three different mechanisms by which training-related brain changes might result in relatively preserved function in musicians as compared to non-musicians with cerebral lesions. Next, we review the neuropsychological literature examining musical ability in professional musicians following brain damage, specifically of vascular, tumoral and epileptic aetiology. Finally, given that assessment of musician patients can greatly inform our understanding of the influence of premorbid experience on postmorbid recovery, we suggest some basic guidelines for the future evaluation of relevant patients.
