Transient global amnesia during a professional cello concert.

Transient global amnesia (TGA) is a great curiosity in medicine, the underlying pathophysiology of which remains under debate. When an episode occurs during the performance of a task requiring refined technical skills and an intense level of concentration such as a musical performance, it draws attention to the relationship between memory and performance. It also raises questions of access to procedural memory and other aspects of stored information. We encountered a renowned and highly proficient musician who was amnestic for a challenging concert.
