What is late-onset Alzheimer disease and how is it inherited?

Late-onset Alzheimer disease is a form of Alzheimer disease that begins to affect people after the age of 65. The genetic causes of late-onset Alzheimer disease are less clear. No gene that definitely causes the condition has been identified. However, a gene called APOE has been studied extensively as a risk factor for the disease. In particular, one form (or allele) of this gene seems to increase an individual's risk for developing type 2 Alzheimer disease. [1]
