This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is investigating how certain brain and psychiatric conditions affect the ability to tell the difference between real experiences and imagined ones. Researchers will give participants special memory tests to measure this ability. The study includes people with conditions like Alzheimer's disease, frontotemporal dementia, Lewy body dementia, Parkinson's disease, and bipolar disorder, as well as healthy volunteers.
Scientists have noticed that some psychiatric and brain conditions make it harder for people to distinguish between things they actually experienced and things they imagined or thought about. Understanding this problem better could help doctors diagnose and treat these conditions more effectively.
