Never too old.

摘要

In March, 2010, a 75-year-old woman was referred to us because of a 6-month history of progressive dementia. Her illness started with gait apraxia and progressed to cognitive decline with variable degrees of sphincter incontinence. She was an otherwise healthy woman with no history of previous medical conditions, and a widow of 15 years since her husband had died from a myocardial infarction. She had had three uneventful pregnancies, had never undergone surgery or blood transfusions, and did not come from a region with high HIV prevalence.
