摘要

M s. M, age 71, was diagnosed with Alzheimer’s disease sev eral months ago and her clinical - presentation and Mini-Mental Status Exam score of 22 indicates mild dementia. In addition to chronic medications for hypertension, Ms. M has been taking lorazepam, 1 mg, 3 times daily, for >15 years for unspecified anxiety. Ms. M becomes more confused at home over the course of a few days, and her daughter brings her to her primary care physician for evaluation. Recognizing that benzodiazepines can contribute to delirium, the physician discontinues lorazepam. Three days later, Ms. M’s confusion worsens, and she develops nausea and a tremor. She is taken to the local emergency department where she is admitted for benzodiazepine withdrawal and diagnosed with a urinary tract infection.
