In line with the categorical definition of mental disorders according to the DSM-5, almost all studies consider depression and personality disorders as two separate conditions, even though they frequently present in clinical practice as coincident rather than truly co-morbid conditions. A co-morbid personality disorder (mostly cluster B and C 1 ) is found in about half of patients with depression, and is consistently associated with unfavourable clinical indicators—such as duration of episode, symptom severity, recurrence of depression, and poor psychosocial functioning. Also, patients with personality disorder are at high risk for depression during their lifetime. Prevalence of depression can vary between personality disorders, but can be up to 90%. 2.
