title: Recognition and treatment of dysthymia in elderly patients.
abstract: This review focuses on recent literature concerning dysthymia in the elderly population. Epidemiological data and clinical picture, diagnostic and therapeutic issues are evaluated and discussed. Although depressive syndromes are common in older patients, prevalence rates of dysthymia in the elderly are lower than in younger adults. This finding may be the consequence of the diagnostic criteria provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM) which are not specific for older adults. Other factors that complicate making diagnoses of dysthymia in older individuals are comorbid general conditions, cognitive deterioration and disorders, and frequent adverse life events (e.g. bereavement). The effects of these factors should be better defined to clarify whether elderly dysthymia is underestimated and if modified diagnostic criteria should be provided. A few researchers have identified a series of clinical features that are clearly different in the elderly and in young adult patients with dysthymia. These features are particularly related to the late onset and to the peculiar comorbidity of this disorder and suggest that dysthymia is a different disorder in the elderly. Drug treatment of depressive conditions in the elderly is currently based on new antidepressants [selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors, norepinephrine (noradrenaline) reuptake inhibitors, benzamides]. These agents have an improved adverse effect profile compared with some of the older agents. Moreover, very few systematic studies have been performed using these drugs in samples of older patients with dysthymia and available data do not allow conclusions on drug choice and dosage. Besides, no specific data are available concerning the psychotherapy of dysthymia in this age group. All these topics need to be further investigated in studies comparing the elderly with control groups of younger patients with dysthymia.
