    Description of Event or Problem · 1

    SUMMARY: THE EXTENT TO WHICH DEEP BRAIN STIMULATION (DBS) CAN IMPROVE QUALITY OF LIFE MAY BE PERCEIVED AS A PERMANENT TRADE-OFF BETWEEN NEUROLOGICAL IMPROVEMENTS AND COMPLICATIONS OF THERAPY, COMORBIDITIES, AND DISEASE PROGRESSION. PATIENTS AND METHODS WE RETROSPECTIVELY INVESTIGATED 123 CONSECUTIVE AND NON-PRESELECTED PATIENTS. INDICATIONS FOR DBS SURGERY WERE PARKINSON'S DISEASE (82), DYSTONIA (18), TREMOR OF DIFFERENT ETIOLOGY (21), HUNTINGTON'S DISEASE (1) AND GILLES DE LA TOURETTE SYNDROME (1). AES WERE DEFINED AS ANY UNTOWARD CLINICAL OCCURRENCE, SIGN OR PATIENT COMPLAINT OR UNINTENDED DISEASE IF RELATED OR UNRELATED TO THE SURGICAL PROCEDURES, IMPLANTED DEVICES OR ONGOING DBS THERAPY. RESULTS OVER A MEAN/MEDIAN FOLLOW-UP PERIOD OF 4.7 YEARS (578 PATIENT-YEARS) 433 AES WERE RECORDED IN 106 OF 123 PATIENTS (86.2%). THERE WAS NO MORTALITY OR PERSISTENT MORBIDITY FROM THE SURGICAL PROCEDURE. ALL SERIOUS ADVERSE EVENTS (SAES) THAT OCCURRED WITHIN 4 WEEKS OF SURGERY WERE REVERSIBLE. NEUROLOGICAL AES (193 IN 85 PATIENTS) AND PSYCHIATRIC AES (78 IN 48 PATIENTS) WERE DOCUMENTED MOST FREQUENTLY. AES IN 4 PATIENTS (SUICIDE UNDER GPI STIMULATION, WEIGHT GAIN >20 KG, IMPAIRMENT OF GAIT AND SPEECH, COGNITIVE DECLINE >2 YEARS FOLLOWING SURGERY) WERE SEVERE OR WORSE, AT LEAST POSSIBLY RELATED TO DBS AND NON REVERSIBLE. IN PD 23.1% OF THE STN-STIMULATED PATIENTS EXPERIENCED NON-REVERSIBLE (OR UNKNOWN REVERSIBILITY) AES THAT WERE AT LEAST POSSIBLY RELATED TO DBS IN THE FORM OF IMPAIRED SPEECH OR GAIT, DEPRESSION, WEIGHT GAIN, COGNITIVE DISTURBANCES OR URINARY INCONTINENCE (SEVERITY WAS MILD OR MODERATE IN 15 OF 18 PATIENTS). AGE AND HOEHN <(>&<)>YAHR STAGE OF STN-SIMULATED PD PATIENTS, BUT NOT PREOPERATIVE MOTOR IMPAIRMENT OR RESPONSE TO LEVODOPA, SHOWED A WEAK CORRELATION (R = 0.24 AND 0.22, RESPECTIVELY) WITH THE NUMBER OF AES. CONCLUSIONS DBS-RELATED AES THAT WERE SEVERE OR WORSE AND NON-REVERSIBLE WERE ONLY OBSERVED IN PD (4 OF 82 PATIENTS; 4.9%), BUT NOT IN OTHER DISEASES. PD PATIENTS EXHIBITED A SIGNIFICANT RISK FOR NON-SEVERE AES MOST OF WHICH ALSO REPRESENTED PREEXISTING AND PROGRESSIVE AXIAL AND NONMOTOR SYMPTOMS OF PD. MILD GAIT AND/OR SPEECH DISTURBANCES WERE RATHER FREQUENT COMPLAINTS UNDER VIM STIMULATION. GPI STIMULATION FOR DYSTONIA COULD BE APPLIED WITH NEGLIGIBLE DBS-RELATED SIDE EFFECTS. REPORTED EVENTS: A (B)(6)-YEAR-OLD PATIENT WITH GLOBUS PALLIDUS INTERNUS (GPI) DEEP BRAIN STIMULATION (DBS) FOR PARKINSON'S DISEASE (PD) COMMITTED SUICIDE 18 MONTHS AFTER IMPLANT, AND THIS WAS CONSIDERED AT LEAST POSSIBLY RELATED TO DBS. IT WAS NOTED THIS PATIENT HAD A HISTORY OF SEVERE DEPRESSION, AND THAT THEY HAD EXPERIENCED SIGNIFICANT IMPROVEMENT LEVODOPA-INDUCED HYPERKINESIA AS WELL AS TARDIVE DYSKINESIAS UP UNTIL THEIR DEATH. IT WAS NOT POSSIBLE TO ASCERTAIN SPECIFIC DEVICE INFORMATION FROM THE ARTICLE OR TO MATCH THE REPORTED EVENT WITH ANY PREVIOUSLY REPORTED EVENT.
