Depression in the Elderly: Recognition, Diagnosis, and Treatment

LOUIS A. CANCELLARO, PhD, MD, EFAC PsychProfessor Emeritus and Interim ChairETSU Department of Psychiatry & Behavioral SciencesDepression in the Elderly: Recognition, Diagnosis, and TreatmentDiagnosisDiagnosing depression in elderlyUse family + patient for historyReport >2 weeks history of (one or more): Loss of energy, loss of interests Increase in somatic symptoms w/o adequate physical explanation Behavioral and/or personality change Suicidal tendencies DelusionsMDDThe symptoms cannot be the result of a medical illness, alcohol or drug usage, medications, or other psychiatric disorder.Atypical Presentation of the Geriatric PatientOlder patients are more likely to report somatic complaints and less depressed mood than younger adults.Older depressed patients may present with a masked presentation, i.e., the patient reports physical rather than mood complaints such as back pain or constipation.
