alzheimer
Synonym discussion
Sense: adjective/1
All three terms relate to health conditions in older adults, but they differ in scope. 'Alzheimer' refers specifically to one named disease. 'Dementia-related' covers a broader category of brain disorders that affect memory and thinking, of which Alzheimer's is the most common type. 'Cognitive' is wider still — it applies to any mental process (memory, reasoning, attention), not just disease contexts. 'Geriatric' relates to old-age medicine generally, not specifically to brain disorders. For example: 'The hospital runs Alzheimer trials for patients with early-stage memory loss,' but 'The geriatric ward treats elderly patients with many different conditions, including dementia-related illnesses.'

Etymology
Named after Dr. Alois Alzheimer (1864–1915), the German psychiatrist and neuropathologist who first described the distinctive brain changes of the disease in a patient named Auguste Deter in 1906. The adjective 'Alzheimer' (short for 'Alzheimer's disease + adjective suffix') came into medical English usage in the early 1900s and is now the standard attributive form in clinical and research contexts.
