Surgery has been shown to be an effective way of controlling the seizures associated with epilepsy.
A new study from a team working at Washington University School of Medicine in St. Louis, Missouri also found that operations could improve long-term quality of life.
Doctors assessed the records from the past 26 years and found half of the epilepsy sufferers who have received surgery reported that they no longer were subject to seizures, while 80 per cent believe they have an increased quality of life post surgery.
"In cases where medical therapy fails to control seizures, epilepsy surgery is a safe and effective treatment option," said the lead author of the study Dr Matthew Smyth.
He also questioned why it remains an under-used form of treatment for the condition.
According to the Brain Research Trust, the condition affects around one in every 131 people in the UK and is responsible for 500 deaths a year.
