Hi. I am writing in regard to my Dad who is 74 and has been diagnosed at least four years. He is on Sinemet CR bid (don't know dosage). My Mom and I have noticed a recent sharp decline in hhis memory and his temper. He can't remember to turn the stove off, turn the water off after using (such as brushing his teeth), the names of his three grandchildren, etc. He at times can't even remember his birth year. Another sharp change is his temper. Since diagnosis his temper would flare in episodes but now it seems to ba almost continous. We all walk on eggshells because we don't know what will set him off. As of yet there has been no physical violence but I worry about my Mom being so close. He refuses to see a neurologist and hhis internal medicine MD tries but Dad won't go to see him that often. Mom is under much stress but won't seek out a support group. My main question, is this the PD worsening or something else (Alzheimers?). Any comments? As a medical professional I worry about both of them but my speciality is maternity, not neurology. I appreciate either personal mail or on the board--whatever you deem appropriate. Thanks in advance Sharon :( [log in to unmask]
