Do Alzheimer's patients need to see a doctor regularly? My primary care doctor says no.

This is my Husband and he went through all the test bloodwork and scans and the final diagnosis was alzhemiers. He has not seen a doctor in year and half. Has tried all the meds for this dread disease for 3 plus years only getting worse. Don't know if I should be taking him to be checked as I feel I need to know what stage he is in with this.

I would have your parent see a Neurologist so the diagnosis is confirmed and he is on the best treatment plan
