Me. Kunik et al., DIAGNOSTIC RATE OF COMORBID PERSONALITY-DISORDER IN ELDERLY PSYCHIATRIC-INPATIENTS, The American journal of psychiatry, 151(4), 1994, pp. 603-605
Among 547 elderly inpatients grouped by DSM-III-R axis I diagnoses, th
e diagnostic rate of comorbid personality disorder varied four-fold, f
rom 6% in patients with an organic mental disorder to 24% in those wit
h major depression. The previously reported low prevalence of comorbid
personality disorder in geriatric patients may be due to its lower ra
te of diagnosis among patients with organic mental disorders.
