Besides what the hospital prescribe him? I know his meds are important but sometimes in the mean time it would be nice to give him things such as DIY oils or something soothing to him. I have an 83 year old dad that is in and out of the hospital and sometimes being in the hospital every couple months is tiring. He has slight dementia but otherwise capable of doing things himself without any problems. I get tired of the hospital at times and we only have 1 available where I live so they know him quite well.
