Wondering if a symptom of advanced Parkinson's is hypervigilance? My husband was previously a very, very laid back person, rolled with everything and now he seems to be terribly concerned about when the mail comes, if a light is on or off, --lots of little things, but it is starting to drive me crazy. He was diagnosed 14 years ago at age 49 and had DBS 7 years ago, but lately has started to deteriorate and cannot really go out much anymore. He will be having hip replacement in a couple of weeks and that has kept him down for the last few months. Is is not enough to do or do you think it is from the PD?
