A 75-year-old woman seems to be losing her memory and getting confused easily. Her family also reports that she's been seeing things that aren't there. She's had a few falls recently. What could be the cause?
This combination of cognitive symptoms, visual hallucinations, and falls could suggest a diagnosis of dementia with Lewy bodies. This condition often presents with cognitive fluctuations, vivid visual hallucinations, and Parkinsonism (movement symptoms like those seen in Parkinson's disease), which can include falls. An evaluation by a neurologist, including possible imaging studies, would be appropriate.
