Ravel's neurological illness.

In the last 10 years of his life, Maurice Ravel (1875-1937) experienced a gradually progressive decline in neurological function. Dr. Alajouanine examined Ravel, noting the presence of aphasia and apraxia with relative preservation of comprehension and memory. The exact diagnosis remains unclear, but the likelihood of a progressive degenerative disorder, such as frontotemporal dementia, is herein discussed.
