My mother has Alzheimer s disease (3 years). She s very noisy most of the day, screaming, yelling, lalalalalalla, babababa, that type of thing. We live in an apartment and I don t want her in a facility. We tried that and she was sexually molested by another resident. She is currently taking Lorazepam 0.5 mg. I don t think it is helping. Is there any other medication that can calm her down?
