Surgery in the back of the brain can attain excellent results if it is conducted early, according to a study published in the scientific journal, Epilepsy and Behavior.Currently this type of surgery is rarely performed, because it is associated with a high number of failures due to the fact that it is extremely difficult to localise the origin from which the seizures spread in this part of the brain.A team of researchers led by Dr Stefano Francione, at the Niguarda Ca’ Granda Hospital, in Milan, analysed the outcome of brain surgery in 125 adults and 83 children who had drug- resistant epilepsy, and in whom the focus of the epilepsy was at the back of the brain.They followed the patients for at least five years after surgery with electroencephalography (EEG), magnetic resonance imaging (MRI) and neurologic and neuropsychological evaluation.They found that seizure freedom was achieved in 70% of individuals following surgery, whilst a further 10% only had rare disabling seizures following surgery.Importantly, the earlier the surgery was performed the more likely it was to be successful, with best results being obtained when the operation was carried out in childhood.“Duration of epilepsy represents a most consistent predictor of surgical outcome, with early surgery being correlated with higher chances of surgical success,” the authors write.  “We recommend an early surgical referral in cases of [drug resistant] posterior cortex seizures,” they add.They also note that surgical failure could be predicted as early as within the first six months following surgery.Author: Dr Özge ÖzkayaClick here for more articles about other treatments for epilepsy.
