With the growing number of Americans over the age of 65 years, the high incidence of geriatric depression has become a major concern in the United States. Age-related circumstances--increased incidence of illness, bereavement, financial difficulties, and institutionalization--may contribute to an increased rate of depression in this age group. The signs and symptoms of depression in elderly patients are similar to those seen in younger individuals; therefore, standard Diagnostic and Statistic Manual III (DSM-III) criteria are reliable for making a diagnosis. However, symptoms such as insomnia, obsessional thought, and hypochondriasis may be relatively increased in the elderly patient; and the diagnosis of geriatric depression can be complicated by signs and symptoms of depression that may overlap with those of dementia. In the geriatric group, the mainstay of pharmacotherapy has been the reuptake antidepressant agents. Choice of antidepressant therapy is largely based on the side-effect profile. Thus, the fewer and less severe side effects associated with trazodone make it a suitable drug choice in these patients. Trazodone has been shown to demonstrate comparable efficacy to the other reuptake and monoamine oxidase inhibitors, but has the advantages of a low cardiovascular-risk profile, extremely low suicide toxicity, absence of anticholinergic side effects, and minimal effects on cognition.
