Somatic Symptom Disorder as a Prodrome of Alzheimer Disease and Successful Treatment of Pain and Agitation With Electroconvulsive Therapy: A Case Report.

Neuropsychiatric symptoms in dementia can be heterogeneous and hard to treat, though electroconvulsive therapy (ECT) is becoming more widely accepted as a viable treatment option. Here, we describe a patient with Alzheimer disease (AD) who developed Somatic Symptom Disorder as a prodrome to cognitive and functional decline, though atypical, primary affective disorder in AD was also on the differential. This patient further developed debilitating anxiety and agitation that was refractory to multiple behavioral and pharmacological interventions. ECT was able to treat the patient's neuropsychiatric symptoms, resulting in sustained, full remission with minimal transient, cognitive side effects. This case depicts a rare presentation of AD and further adds to the growing body of literature that suggests ECT is safe and effective for treating neuropsychiatric symptoms in dementia.
