Depression in the older adult

Older adults who visit the primary care physician's office often exhibit depressive symptoms. The challenge for the physician and other office staff is to determine what these symptoms mean: Loneliness? Fear? Grief? A consequence of a coexisting medical condition? A DSM depressive disorder? Or something else? Addressing ambiguous symptoms that may represent a depressive disorder may be difficult in the busy office setting. The findings of one recent study suggest that it is not lack of knowledge that impedes the recognition of depression but rather the conditions under which clinical decision making occurs. The process of ruling out medical diagnoses and opening the door to consider a mental health diagnosis can be time-consuming and circuitous, especially if the clinician is not already familiar with the patient or if the clinician who is familiar with the patient perceives insufficient time to deal with the issues raised by opening the door. The fundamental challenge for the primary care clinician as aging baby boomers inundate the health care system is to restructure office practice to recognize, assess, and manage geriatric syndromes including depression. The underlying principle for successful restructuring is acknowledging that these syndromes have multiple causes requiring multifaceted interventions. Operationally, doing simple things consistently and well may have significant impact. By consistently recognizing biologic and psychosocial risk factors for depression, by taking a careful history (including the two-question screen), and by conducting a thorough physical examination, the office-based clinician will generally have a strong clinical hunch about the presence or absence of a depressive disorder and any comorbid medical and neuropsychiatric conditions. Armed with this information, additional laboratory and brain imaging studies and subsequent management strategies are straightforward.
