Schizophrenia is often confused with dissociative identity disorder. What lies behind that confusion?
ABoth were first described by Eugen Bleuler in 1911
BBoth are treated with the same class of medication
CBoth involve two or more distinct personalities
DThe name comes from Greek roots meaning a splitting
Answer & Solution
Correct answer: D. The name comes from Greek roots meaning a splitting
1. Schizophrenia is not a condition involving a split personality and is not the same as dissociative identity disorder.
2. The word was coined by the Swiss psychiatrist Eugen Bleuler in 1911 from Greek roots meaning a splitting of psychic functions.
3. That etymology, not any shared symptom, is what invites the confusion between the two conditions.
4. Two or more distinct personalities define dissociative identity disorder alone, so that option repeats the very error being corrected.
