Notes About Alzheimer Disease
Alzheimer disease is an eponym (named after a person). It is named for Alois Alzheimer (1864–1915), who discovered pathological features of dementia while a student.
For clarity and consistency, it is more commonly written as Alzheimer disease rather than the possessive form Alzheimer’s disease.
The ‘i’ before “e” rule does not apply when spelling Alzheimer disease.
