AD4 (medical condition): A degenerative brain disease characterized primarily by progressive dementia. Type 4 has an early onset (starts before the age of 65). It is caused by mutations in the PSEN2 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.
