Alzheimer disease type 1: A degenerative brain disease characterized primarily by progressive dementia. Type 1 has an early onset (starts before the age of 65). It is caused by mutations in the APP gene which results in the 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. More detailed information about the symptoms, causes, and treatments of Alzheimer disease type 1 is available below.
