[Anxiety as a concomitant symptom of depression in the elderly]

Anxiety is a symptom frequently encountered in elderly depressed patients. It is supposed to have an unfavourable prognostic impact. We studied the frequency of psychic anxiety and its relationship to demographic, social and clinical variables in a group of 54 elderly depressed patients admitted to a gerontopsychiatric day-clinic. Severity of depression, cognitive performance, functional level, social situation and life satisfaction were studied by means of standardized instruments. In about half of the patients studied, we found significant psychic anxiety. Compared to the other depressed patients, patients with anxiety suffered more frequently from cognitive impairment and were more dissatisfied with the acceptance of their disease by other persons. They more frequently lived together with other persons in one household. When leaving psychic anxiety out of consideration as a depressive symptom, the severity of depression was not different in patients with and without anxiety. Anxious patients were equally responsive to day-clinic treatment as non-anxious patients. However, duration of treatment was considerably increased. Thus, elderly depressed patients with anxiety show particular psychosocial and clinical features and require special attention in diagnostics and treatment.
