    DOSHI, P. K., CHHAYA, N. A., BHATT, M. A. BILATERAL SUBTHALAMIC NUCLEUS STIMULATION FOR PARKINSON'S DISEASE. NEUROL INDIA. 2003; 51(1): 43-48. HTTP://LIBCONTENT.MEDTRONIC.COM:2133/PUBMED/12865514 SUMMARY: HIGH FREQUENCY STIMULATION OF THE SUBTHALAMIC NUCLEUS (STN) IS KNOWN TO AMELIORATE THE SIGNS AND SYMPTOMS OF ADVANCED PARKINSON'S DISEASE. WE STUDIED THE EFFECT OF HIGH FREQUENCY STN STIMULATION IN 23 PATIENTS. TWENTY-THREE PATIENT'S SUFFERING FROM SEVERE PARKINSON'S DISEASE (STAGES III-V ON HOEHN AND YAHR SCALE) AND PARTICULARLY BRADYKINESIA, RIGIDITY, LEVODOPA-INDUCED DYSKINESIAS UNDERWENT BILATERALIMPLANTATION OF ELECTRODES IN THE STN. PREOPERATIVE AND POST-OPERATIVE ASSESMENT'S OF THESE PATIENT'S AT 1, 3, 6, AND 12 MONTHS FOLLOW UP IN "ON" AND "OFF" DRUG CONDITIONS WAS CARRIED OUT USING UNIFIED {PARKINSON'S DISEASE RATING SCALE, HOEHN AND YAHR STAGING, (B)(6) ACTIVITIES OF DAILY LIVING SCORE AND VIDEO RECORDINGS. AFTER ONE YEAR OF ELECTRICAL STIMULATION OF THE STN, THE PATIENT'S SCORES FOR ACTIVITIES OF DAILY LIVING AND MOTOR EXAMINATION SCORES (UNIFIED PARKINSON'S DISEASE RATING SCALE PARTS II AND III) OFF MEDICATION IMPROVED BY 62% AND 61%RESPECTIVELY (P<(><<)>0.0005). THE SUBSCORES FOR THE AKINESIA RIGIDITY, TREMOR AND GAIT ALSO IMPROVED. (P<(><<)>0.0005). THE AVERAGE AGE LEVODOPA DOSE DECREASED FROM 813 MG TO 359 MG. THE COGNITIVE FUNCTIONS REMAINED UNCHANGED. TWO PATIENTS DEVELOPED DEVICE RELATED COMPLICATIONS AND TWO PATIENTS EXPERIENCED ABNORMAL WEIGHT GAIN. BILATERAL SUBTHALAMIC NUCLEUS STIMULATION IS AN EFFECTIVE TREATMENT FOR ADVANCED PARKINSON'S DISEASE. IT REDUCES THE SEVERITY OF "OFF" PHASE SYMPTOMS, IMPROVES AXIAL SYMPTOMS AND REDUCES LEVODOPA REQUIREMENTS. THE REDUCTION IN LEVODOPA DOSE IS USEFUL IN CONTROLLING DRUG-INDUCED DYSKINESIAS. REPORTED EVENT: 1. 2 PATIENTS SUFFERING FROM SEVERE PARKINSON'S DISEASE WERE READMITTED TO THE HOSPITAL FOR REPROGRAMMING AFTER DISCHARGE AS THEY LOST THEIR INITIAL BENEFIT OF PROGRAMMING AND DETERIORATED IN THEIR CLINICAL CONDITION. BOTH PATIENTS HAD LESS THAN SATISFACTORY RESPONSE AT THE TIME OF DISCHARGE. THEIR SYMPTOMS IMPROVED FOLLOWING CHANGE OF CONTACTS AND REPROGRAMMING. FURTHER INFORMATION HAS BEEN REQUESTED; A SUPPLEMENTAL REPORT WILL BE SUBMITTED IF ADDITIONAL INFORMATION IS RECEIVED. SEE ATTACHED LITERATURE ARTICLE.
