Alzheimer’s disease is a progressive, irreversible, degenerative neurologic disease that begins insidiously and is characterized by gradual losses of cognitive function and disturbances in behavior and affect. Alzheimer’s disease is not found exclusively in the elderly; in 1% to 10% of cases, its onset occurs in middle age. A family history of Alzheimer’s disease and the presence of Down syndrome are two established risk factors for Alzheimer’s disease.

If family members have at least one other relative with Alzheimer’s disease, then a familial component, which non specifically includes both environmental triggers and genetic determinants, is said to exist. Genetic studies show that autosomaldominant forms of Alzheimer’s disease are associated with early onset and early death.
