While working in a Frankfurt asylum for the mentally ill in 1901, Alois worked with a woman in her late 40's suffering from short term memory loss and "strange behavioral symptoms."
Auguste D. died in 1906. Alois performed the autopsy and, with the help of a new staining technique, he was able to identify the Beta-Amyloid Plaques and Neurofibrillary Tangles that would one day be synonymous with AD.
Alois first called this "Pre-senile Dementia."
