Alzheimer's disease
When Ms. Deter died of septicemia on 8 April 1906, Alzheimer was informed and her brain was sent to Munich for him to study. Studying samples of her brain under a microscope he noticed neurofibriallry tangles and bundles made up of beta-amyloid plaque, which are two of the main features of the disease.  On 3 November 1906, Alzheimer presented the results of his findings in Auguste's case at the Conference of South-West German Psychiatrists in Tübingen, and he published his findings in the case in 1907.
