Background: Alzheimer's disease (AD) agitation is a distressing neuropsychiatric symptom characterized by excessive motor activity, verbal aggression, or physical aggression. Agitation is one of the causes of caregiver distress, increased morbidity and mortality, and early institutionalization in patients with AD. Current medications used for the management of agitation have modest efficacy and have substantial side effects.

Multiple loss-of-function variants strongly implicate TREM2 as a key regulator of Alzheimer's disease (AD) risk. Accordingly, TREM2 antibodies are currently in development to evaluate the therapeutic potential of TREM2 agonism in neurodegenerative diseases.

Vanderbilt University Medical Center, Nashville, TN, USA.
Background: We report the case of a 79-year-old woman with Alzheimer's disease who enrolled in a clinical study of lecanemab. After the third, biweekly infusion she suffered a seizure followed by aphasia and progressive encephalopathy. Magnetic resonance imaging revealed multifocal cerebral edema and an increased burden of cerebral microhemorrhages compared to pre-trial imaging.
