How can hallucinations be treated?
human
My sister in law has early onset Alzheimers.  She is in stage 7.  She is currently on risperidone.  Nonetheless, she appears to be hallucinating and she screams all day long and awakens several times nightly screaming as well.  Why is she screaming?  How can we help?

Hello thanks for asking from HCMI can understand your concern. Hallucinations in Alzheimer's disease patient develop because of some organic issue in brain. Even medicines used for Alzheimer's especially Memantin could lead to development of psychosis and consequent hallucinations. If on Risperidone her symptoms are persisting then other drugs of second generation antipsychotics can be tried. Olanzapine can become a good option. The drug can be used to treat her hallucination. Newer drugs like Lurasidone can also be used. The drug will help in dementia symptoms too.Please talk with her doctor for this drug.THANKS AND TAKE CARE
