Picks disease is difficult to distinguish from dementia of the Alzheimers type, although the early stages of Picks disease are more often characterized by personality and behavioral changes, with relative preservation of other cognitive functions, and it typically begins before 75 years of age. Features of Kluver-Bucy syndrome e.g., hypersexuality, placidity, and hyperorality are much more common in Picks disease than in Alzheimers disease.
