Emil Kraepelin - founder of modern psychiatry

Emil Kraepelin was born in 1856 in what was then the German Confederation and was a student at the University of Leipzig and University of Wurzburg where he studied medicine where he developed an interest in psychology.

He moved away from the traditional symptomatic view of mental illness and developed a clinical view which grouped diseases based on the patterns over time rather than the similarity of the symptoms. He is also credited with distinguishing psychosis between manic depression and dementia praecox which had previously been grouped together as psychosis.

He worked alongside Alois Alzheimer (born 1864 in German Confederation) and part of this work included the identification that a biological pathology underlied each of the disorders. It was Alois who identified the first published case of presenile dementia with Kraepelin subsequently terming it Alzheimer's disease.


For more information on Alzheimer's disease see the Alzheimer's Society who have some great resources on on their website.
