My husband (of 6 years) is in his late 60's. He was diagnosed with MCI of an unknown origin last spring, by a neurologist. He is having the comprehensive 4 hour cognitive exam in April. My husband's grandfather had Parkinson's and I noticed the neuro asking him a lot of questions that I later realized were Parkinson's related. For many months now he has been suffering with a very "stiff" back for which PT has done little to help. This has NOT been diagnosed as being related to Parkinson's but it may be another piece of the puzzle. He does not have a constant or blatant "tremor" but he rubs his thumb and index finger together when his left hand is not "busy" and when he is resting...such as watching TV...his feet are never still...they move around constantly. He is Romberg positive. He also has issues with short term memory that is getting worse. His long term memory appears fine. Do patients with Parkinson's also suffer cognitive impairment or are these two completely separate issues? As I said, he has not been diagnosed with anything except MCI at this point but I am told that they will also speak with me at the long exam and I am wondering what may be significant to mention to them.
