Alzheimer's disease: [20] This serious brain disorder was first described in a scientific journal in 1912, and was given its name in honour of the German neurologist Alois Alzheimer (1864–1915). For many decades the term was largely confined to specialist medical journals, but in the 1970s, as the disease became better known, it seeped into the public domain.
