Your uncle with dementia is experiencing visual hallucinations, which are common in certain types of dementia, especially Lewy body dementia[5][13]. These hallucinations can seem very real and vivid to the person experiencing them, even though they aren’t actually happening[13].
In dementia, the brain undergoes changes that affect how it processes and interprets visual information[9]. This can lead to seeing things that aren’t really there, like a floating couch. These hallucinations often involve everyday objects or people, and can last for a while[13].
Visual hallucinations are particularly common in Lewy body dementia, affecting many people with this condition[5]. They can also occur in other types of dementia, like Alzheimer’s disease, though less frequently[9].
It’s important to remember that for your uncle, the floating couch seems completely real. Arguing with him about it probably won’t help and might just upset him[7]. Instead, try to reassure him and gently redirect his attention to something else[7].
If the hallucinations are causing distress or interfering with daily life, it’s a good idea to talk to your uncle’s doctor. They might be able to suggest ways to manage the hallucinations or adjust his medication if needed[13].
Remember, hallucinations in dementia are caused by changes in the brain, not by any fault of the person experiencing them. With understanding and support, you can help your uncle feel more comfortable and secure, even when he’s seeing things that aren’t there.
