Visual hallucinations on a background of cognitive decline

Mdm Q was a 71-year-old retired hawker who first presented to a primary care practice two years earlier with short-term memory difficulties, such as misplacing things without independent retrieval and forgetting recent conversations. She had no aphasia, agnosia or apraxia. She used written reminders of the time to pick up her granddaughter from school and was otherwise independent in instrumental activities of daily living (iADL). Physical examination, including full neurological examination, was normal.
