A 29-Year-Old With Iron Deficiency and Multifocal Cerebral Infarcts.

A 29-year-old man with a history of mood disorder was admitted with acute encephalopathy after friends had requested a welfare check. He initially was disoriented, with poor recall and reporting delusions of alien interaction. During interview, he was falling asleep intermittently but was able to be aroused. He denied any new symptoms except discomfort with eating because of insects inside his body. His friend reported the patient used alcohol 1 to 2 drinks weekly, and LSD and marijuana use the weekend prior. He also has a remote history of recreational cocaine use in college that stopped because of nosebleeds. The patient reported a daily medication for anxiety, but he was unable to recall the name.
