Delusions and hallucinations seem very real to the person who is having them and can cause a lot of distress. It is important to take delusions seriously and never dismiss them as a symptom of dementia. The person is experiencing real fear or anger and distress, whether the belief is true or not. A hallucination is a sensory experience that occurs in the absence of actual sensory stimulation. Hallucinations in dementia are most commonly visual but can involve other senses like hearing and touch.
