Question: What is (are) Late-Onset Familial Alzheimer Disease ?
Answer: Late-onset familial Alzheimer disease is a form of familial Alzheimer disease that begins after age 65. In general, Alzheimer disease (AD) is a degenerative disease of the brain that causes gradual loss of memory, judgement and the ability to function socially. The exact underlying cause of late-onset familial AD is not completely understood; however, researchers suspect that it is a complex condition, which is likely associated with multiple susceptibility genes (such as the APOE e4 allele) in combination with environmental and lifestyle factors. Although complex conditions do tend to cluster in families, they do not follow a clear-cut pattern of inheritance. There is no cure for AD. Treatment is supportive and based on the signs and symptoms present in each person.
