A 33-year-old woman with a history of bipolar disorder attends A&E

A 33-year-old woman with a history of bipolar disorder attends A&E, feeling generally unwell. She reports feeling nauseous and lethargic. She started with dysuria and urinary frequency a couple of days ago, but feels “much worse” today. On examination, she has dry mucus membranes, a notable tremor, and myoclonus. Routine bloods are done, showing a stage 1 AKI and mildly raised infective markers, but no other abnormalities. She reports being fully compliant with her medication, and her bipolar has been stable for over a year.
