Biographical Note for alzheimer's disease

Alzheimer, Alois (1864–1915), German neurologist. Alzheimer was noted for his work in the pathology of the nervous system. The majority of his medical contributions centered on neurohistology. Alzheimer published papers on topics that include acute alcoholic delirium, schizophrenia, epilepsy, syphilitic meningomyelitis and encephalitis, gliosis, Huntington's disease, and hysterical bulbar paralysis. In 1894, he published a noteworthy description of arteriosclerotic atrophy of the brain. With Franz Nissl, he produced Histologic and Histopathologic Studies of the Cerebral Cortex (1904–08), a six-volume encyclopedia that described normal and abnormal structures in the central nervous system. In 1907 he published his classic description of presenile dementia. The disease was later named in his honor by the German psychiatrist Emil Kraepelin.
