Once placed on the ward, they stopped pretending they had symptoms and behaved normally. Only discharged once doctor was convinced they were sane.
Staff diagnosed 11 with Sz and 1 with bipolar. Never detected their sanity and said their behaviour showed no abnormalities, but interpreted this behaviour as a schizophrenic person.
All were diagnosed on leaving with schizophrenia "in remission".
