It's just his dementia

A man with a known, previously stable mild dementia becomes acutely more confused and agitated over two days after starting a new medication for a chest infection, with clear fluctuation between calm and agitated states within the same day — a pattern his usual carers say is new. A staff member documents this simply as 'his dementia getting worse' without further assessment.
