Has anyone experience of hallucinations being part of dementia or stroke symptoms? My DM is seeing 'people' all over her garden and sitting in her house. They even smell bad, according to her. She seems reasonably sharp in most other respects & gets very indignant and angry if we try to say that there's nothing there, so we're mostly opting to humour her at the moment. She has been assessed by a doctor and is being sent for a brain scan shortly but is there anything we can usefully do in the meantime?
