dementia praecox
Very LowHistorical / Academic / Technical
Definition
Meaning
An obsolete historical term for what is now known as schizophrenia, particularly referring to a progressive, early-onset mental deterioration.
In modern usage, it is exclusively a term of historical or academic interest in psychiatry and psychology, used to discuss the evolution of diagnostic concepts. It is not used in current clinical practice.
Linguistics
Semantic Notes
The term is a direct borrowing from Latin ('praecox' meaning 'early ripening' or 'premature'). Its use signifies a specific historical model of severe mental illness, not a current diagnosis. Using it today risks appearing antiquated or insensitive.

FAQ
Frequently Asked Questions
Yes, broadly. 'Dementia praecox' is the historical precursor to the modern diagnosis of schizophrenia. The concepts overlap but are not identical, as modern schizophrenia is defined by different criteria.
It was replaced by 'schizophrenia' (coined by Eugen Bleuler in 1908) because Bleuler argued the condition was not a 'dementia' (irreversible decline) and did not always have an early ('praecox') onset. The newer term aimed to be more descriptively accurate.
Using it to describe a living person would be incorrect, antiquated, and potentially stigmatizing. Its appropriate use is confined to academic or historical discussion of psychiatric terminology.
The term was popularised and systematically defined by the German psychiatrist Emil Kraepelin in the late 19th and early 20th centuries, though it had been used by others earlier.
