[1] [3] It's estimated only 25–29% of people affected survive to adulthood, and only 10% to the age of 50. [1] The median life expectancy is around 9 years, and the average life expectancy is 16.3 years. [1]

About 60% have a positive family history of Alzheimer's and 13% of them are inherited in an autosomal dominant manner. Most cases of early-onset Alzheimer's share the same traits as the "late-onset" form and are not caused by known genetic mutations.
Research suggests that sleep disturbances in midlife, such as chronic insomnia or sleep apnea, could contribute to neurodegenerative changes that manifest as dementia later in life.
