Dementia praecox to schizophrenia: the first 100 years.
The historical roots of dementia praecox and schizophrenia are described in the context of current nosology and continuing controversies surrounding this nosology. Relevant books and journal articles were reviewed. The information was obtained through computer searches and cross-references from previously published papers. If English translations of foreign language articles were available, they were used; if not, the cross-references were consulted. The psychoses have existed as diagnostic categories from ancient times although their names have changed. Initially, these disorders were considered diseases of the brain, a concept that was swept aside in the United States, influenced by European-derived psychodynamic theories. American clinicians and investigators simply accepted these theories, showing little interest in testing their underlying principles. In contrast, a narrower Kraepelinian approach was adopted outside the United States, and attempts were made to refine its nosology. Because current data supports a central nervous system aetiology for schizophrenia, the concept of dementia praecox warrants resurrection. The authors suggest abandoning the term schizophrenia in favour of the more broad and generic term dementia praecox. Replacing 'schizophrenia' with 'dementia praecox' in the 21st century will facilitate further research and help clarify the nosology of various brain disorders currently included in the schizophrenias.
