[Neuropathologic investigation in autopsies with special emphasis on findings in Alzheimer's disease].

Out of an average total of 1400 autopsies per year, neuropathological examinations were performed in 477 cases between 1997 and 1999 to investigate the incidence of dementias. The majority of the studied subjects were over 50 years old. Bielschowsky's and/or Gallyas's silver methods and, in some cases, protein tau (MAP) immunocytochemistry and amyloid staining were performed beside routine examination.
