[Your help is needed! Autopsy brings new knowledge regarding Alzheimer dementia]

Diagnosis upon autopsy of patients suffering from Alzheimer's disease (AD) and other dementing disorders is required to confirm or reject the clinical diagnosis. Autopsy studies are crucial to validate diagnostic criteria as well as to gain new insights in AD epidemiology, genetics, pathophysiology and therapy. The current decrease of autopsy rates leads to a lack of research which is essential to improve diagnosis and therapy of AD. Only the cooperation between physicians in memory-clinics, general practitioners and neuropathologists can prevent this unfortunate development. Brain-Net, the German brain bank, is a unique approach to provide organisational support for such a concerted action.
