It is named after the German neurologist Alois Alzheimer, who was the first to describe the symptoms and typical brain changes in 1906. The disease is characterized by the slowly progressive loss of nerve cells and nerve cell contacts. Protein deposits (amyloid plaques and tau tangles) can be detected in the brains of those affected.
The clinical picture includes memory and orientation disorders, impaired thinking and judgment and changes in personality. These disorders can be of varying severity in those affected and make it increasingly difficult to go about everyday life normally. The first port of call for complaints is usually the general practitioner. If dementia is suspected, we often work together with specialists (neurology, psychiatry, geriatrics).
Eisai has many years of experience in the field of Alzheimer’s dementia and is working on the development of new drugs to treat the disease.
