Sound waves vs. seizures: new ultrasound approach targets epilepsy without surgery

This early study tests whether MRI-guided high-intensity focused ultrasound (HIFU) can safely heat and destroy small brain areas causing seizures in 13 adults with drug-resistant epilepsy. Participants have visible brain lesions that are too risky or deep for traditional surgery. The main goal is to see if the ultrasound can reach the target temperature needed to ablate the lesion, while monitoring for side effects. If successful, this non-invasive method could offer a new option for people who cannot have open brain surgery.
