It’s widely known that a German physician named Alois Alzheimer discovered what we now call Alzheimer’s Disease. What is not as commonly understood is why. In the early 20th century Alzheimer was part of a new movement that searched for the physical causes of some mental illnesses in the human brain. Alzheimer and his research collaborators had the laboratory tools and expertise to search for microscopic anomalies in the brains of closely observed patients. The abnormalities they observed still characterize a much-feared disease whose incidence is growing globally today.
