    AN ARTICLE ENTITLED ¿PROMISING EFFECT OF VAGAL STIMULATION IN DANISH PATIENTS WITH EPILEPSY¿ WAS RECEIVED. THE AIM OF THIS STUDY WAS TO EVALUATE THE EFFECT OF VNS ON SEIZURE FREQUENCY AND TO INVESTIGATE PATIENT SATISFACTION OF AND QUALITY OF LIFE EFFECTS OF VNS TREATMENT. 94 PATIENTS WERE REVIEWED BETWEEN 1996 AND 2006. 46 PATIENTS EXPERIENCED A REDUCTION IN SEIZURE FREQUENCY AND 38% OF ADULTS REPORTED A POSITIVE EFFECT ON QUALITY OF LIFE WITH A BENEFIT ON LONG-TERM TREATMENT. AROUND 20% ALSO REPORTED A POSITIVE EFFECT ON QUALITY OF LIFE MEASURE LIKE COPYING, MOOD, SELF-CONFIDENCE, AND SOCIAL ABILITIES. IN THE CHILDREN¿S GROUP, 21% REPORT A POSITIVE EFFECT ON QUALITY OF EVERYDAY LIFE FOR THE CHILD AND THE FAMILY, 52-55% REPORTED NO CHANGE AND 10% A NEGATIVE EFFECT. THE PATIENTS HAD MILD SIDE EFFECTS, EXPECT FOR ONE CASE OF VOCAL CORD PARALYSIS. RESULTS ALSO INDICATED THAT TWO CHILDREN WERE REPORTED AS HAVING SUFFERED AN INCREASE IN THE FREQUENCY OF SEIZURES. ANOTHER PATIENT HAD THE VNS REMOVED DUE TO MENTAL SIDE EFFECTS AND EXPERIENCED AN INCREASE IN THE FREQUENCY OF SEIZURES. ADDITIONAL SIDE EFFECTS INCLUDED ONE CASE OF INFECTION, BEHAVIORAL CHANGES, HOARSENESS WITH STIMULATION, STIMULATION DEPENDENT DYSPNEA UPON EXERTION, COSMETIC COMPLAINS, LOSS OF SINGING ABILITY, DIFFICULTIES SWALLOWING, DIFFICULTIES SPEAKING, AND RED, WIDE, OR ITCHY SCARS.
