Focused ultrasounds: What is their future in epileptology? A critical review.

High intensity focused ultrasounds (HIFU) are being increasingly advocated as a useful tool in the management of focal drug-resistant epilepsy. Our aim was to review current literature on the topic and perform an inventory of open trials assessing HIFU effectiveness and safety in epilepsy management. To do so, a review was conducted and yielded one prospective clinical trials, two case reports and one safety study were retrieved, indicating that HIFU is still in its infancy when it comes to focal drug-resistant epilepsy therapy. Efforts should be made to develop this technology using multicentric prospective data with larger cohorts and prolonged follow-up.
