• Alzheimer disease, familial: A degenerative brain disease characterized primarily by progressive dementia. The familial form is very rare and is completely inherited and has an early onset (usually in the 4th decade). It occurs when there is excessive production of a toxic protein (amyloid beta peptide) in the brain which collects into clumps (amyloid plaques) in the brain. These plaques cause damage to nerve cells in the brain.
• Alzheimer disease, familial, 1: An inherited form of Alzheimer's disease that is linked to a defect on chromosome 21q. Alzheimer's disease is a progressive disorder involving degeneration of the brain. The disease mainly affects brain functions involving thinking, memory, personality and behaviour.
