How long does Alzheimer's disease last on average?
Dr. Maurizio Grimaldi
The sporadic form of Alzheimer’s disease on average, given the state of good supportive care, can last from 5 to 20 years. The average, calculated by the Alzheimer’s Association, is around 8 to 12 years.
In general, there is a phase in which learning and memory performance is mildly compromised. This stage can last as short as few months or as long as a few years. This phase transitions into the next, consisting of severe fading of learning and memory capability that develops over the course of a few years.
Finally, the patient with a fully developed clinical picture of the disease falls into a state in which the sense of self is lost. The familiar, although rare, early onset form of the disease rapidly progresses and rarely the patient survives 8 years from the diagnosis.
