Case Report: Depression vs. Early-Onset Alzheimer Disease: The Genetic Counselor's Role

Awareness of depression in the differential diagnosis of Alzheimer disease is essential for genetic counselors seeing patients at risk for early-onset familial Alzheimer disease (EOFAD). The genetic counselor is in a unique position to recognize depression as the cause of symptoms mimicking early-onset Alzheimer disease. While generating a family medical history, the counselor can evoke significant emotional history as well. Based on this information, appropriate referrals can be given for neurological and psychological evaluation. The counselor also serves to explain EOFAD and the benefits and limitations of genetic testing for each individual patient. Whether or not patients choose testing, they can benefit from correct diagnosis of troublesome, or even debilitating, symptoms that imitate symptoms of the feared hereditary disease.
