Longevity can range from 3-10 years after diagnosis, depending on age, sex and medical history. However, the average life expectancy from diagnosis is 4.5 years.

Alzheimer's Disease has a higher percentage in developing countries. It is thought that this is due to the higher life expectancy in these countries, as an increase in age, increases the probability of developing Alzheimer's Disease.
