Hi everyone. I am a caregiver for my dad who was diagnosed with PSP 6 years ago. We live in the US and my dad recently started hallucinating (talking to people who weren't there, reaching for things in the air, seeing things on the walls or floor, etc). He was admitted to the hospital and they ran all imaging and tests which were normal so they are saying it is delirium associated with PSP. Has anyone experienced this with a loved one? They started him in an antipsychotic medication, Seroquel.
