A 50-Year-Old Woman With Confusion and Facial Rash.

Abstract

A 50-year-old woman presented to the ED with a 3-day history of increasing confusion. Prior to her presentation, the patient had been in her usual state of health as reported by her family. She had a history of bipolar disorder and attention-deficit/hyperactivity disorder but had stopped her psychiatric medications for the past 4 days secondary to loss of insurance coverage. History was limited due to the patient's altered state and confusion, and was obtained from family. There was no history of headache, loss of consciousness, weakness of extremities, seizures, fever, or recent trauma. The patient's medical history also included cocaine abuse. The patient's family believed she had been abstinent from cocaine use for several years.
