I was diagnosed with PD twenty years ago. On Dec. 8, 1993 I had a right side pallidotomy and on Dec. 14, 1994 had a left pallidal DBS. the surgeries resulted in my moving from the 85th percentile to the 10th percentile. My drug therapy went from 16 Sinemet CR 200/50 daily and 9 permax 1mg daily to 4 CRs and 2.5 Permax, at a saving of well over $12,000 per annum.
