My 92 year old father is getting more confused. It tends to be worse in the evening. I know about sundowners but I thought that was more with moderate and advanced dementia. He recently passed the MMSE test when I had the doctor check him for dementia symptoms, so I am wondering if his confusion could be depression related. I’ve never really seen anything that compares specific confusion-related depression symptoms with dementia symptoms. Dad's biggest issues are short term memory loss and that he doesn’t think he is home. For example, he asks when we are going home. I think this is a pretty typical dementia symptom but is it also a symptom of depression? I also talked to his doctor and we took him off his pravastatin, which I’ve heard might cause confusion too. I think I heard that it may take up to three weeks for cognition to improve if it is statin related. Anyone that can share experience or knowledge about this is much appreciated.
