Published: 02.12.2025
More than 100 years ago, Alois Alzheimer found the first biological traces of the disease later named after him in the brain of a dementia patient. Since then, research has made many discoveries, but the big breakthrough is still pending. You can learn more about the history of Alzheimer's research, as well as the social dimension of the disease, in the article ▸ Alzheimer's – a Disease makes History.

Alzheimer's disease
Morbus Alzheimer
Alzheimer's disease is a progressive neurodegenerative disorder characterized by cortical atrophy, nerve cell loss, synapse loss, and deposits of amyloid plaques and neurofibrillary tangles, leading to dementia and loss of function. Early symptoms include memory problems, speech disorders, executive deficits, depressive moods, and subtle personality changes. As the disease progresses, global cognitive impairment, aphasia, agnosia, apraxia, and behavioral abnormalities such as apathy, restlessness, and sleep disorders occur. The disease was first described in 1907 by Alois Alzheimer.
