title: Hearing and premorbid personality in paranoid states.
abstract: The author studied the hearing and premorbid personality of 79 patients whose illnesses began before they were 60 years old. Hearing was assessed by pure-tone audiometry and premorbid personality by interviewing relatives. Thirty-two patients had paranoid states, 32 matched patients had recurrent unipolar depression, and 15 patients had schizophrenia. Three paranoid patients and two depressed patients met DSM-III criteria for premorbid paranoid personality. There was no consistent difference in hearing loss between paranoid and depressed patients or between paranoid patients and a population control group. The author concludes that premorbid paranoid personality and hearing loss are not associated with paranoid states in middle age.
