Some doctors are now ordering an old drug called Seroquel. It has been very helpful for those who are hallucinating or become uncontrollable late in the day. One particular family caregiver says it has really helped his wife become easier to manage. You may ask about it.
I agree with Dopaday1. My husband was having delusions and agitation late in the day. The delusions left and the agitation got much better after the Doc put him on Seroquel.
Seroquel works great for my mom as well. Though it is sometimes trial and error to find something that will help. Mom started taking it three years ago with 12.5mg that gradually increased over time and she has just started taking 100mg daily at 4:00 to help with sundowning behaviors.
