A 70-year-old woman was admitted 2 days previously with a urine infection, and yesterday, she developed symptoms consistent with a delirium. Today, her markers of infection have significantly improved; however, her delirium appears to be worsening, and you have just been called to reassess her as she has had a witnessed seizure, which self-terminated after 3 mins. She usually lives at home with her husband, but you have not been able to obtain a collateral history from him yet. To your knowledge, she has no documented cognitive impairment, and her only current medication is lisinopril for her hypertension. She also previously had a curative mastectomy for breast cancer at age 45. What is the most likely cause of seizure for this woman with the information you have to hand?
