For patients with mesial temporal lobe epilepsy (MTLE) that can't be controlled by medications, a minimally invasive laser procedure performed under MRI guidance provides a safe and effective alternative to surgery, suggests a study. The researchers report their experience with MRI-guided SLAH in 13 adult patients with epilepsy mapped to a part of the brain called the mesial temporal lobe. The patients, median age 24 years, had "intractable" seizures despite treatment with antiepileptic drugs.
