In 1998 my husband had 3 surgeries: May, a decompressive laminectomy. September, a colon resection for a fistula caused by diverticulitis and the in Feb. gall bladder surgery. I often wondered if the anesthesia didn't have something to do with the onset of his Parkinson symptoms. He doesn't have the tremors although his handwriting has changed. His main problem is with extreme weakness in his legs. After the surgeries he was sent to PT to strengthen his legs but there was no improvement. In April 2000 after an MRI, blood test and evaluation he was sent to a neurologist who diagnosed Parkinson's. At present he is on Sinemet Cr Tabs 25/100 QID. After starting the Sinemet his gait did improve and the shuffle eased up. But still the weakness. Thanks to this wonderful list we have an appointment with a Movement Disorder Specialist the end of August, Dr. David Riley at University Hospital in Cleveland, Oh. Before this list I had never heard of a MDS. I will be sure to ask him about anesthesia and PD and I will let you know his reply. Thanks again for all the wonderful information Carole Lynch Carepartner for Joe 70/69/? Willoughby, Oh
