Dementia praecox
obsolete medical term for schizophrenia / From Wikipedia, the free encyclopedia
Dementia praecox is a term in Latin which Emil Kraepelin invented and contrasted with a mental illness called manic-depressive insanity [1] which is re-described as Bipolar disorder today.[2] For Kraepelin and other psychiatrists, people diagnosed with manic-depressive insanity often had episodes in which they seemed normal, while people with dementia praecox did not. Dementia is a mental illness which mostly occurs in old people.
