Low Intensity Focused Ultrasound for Epilepsy- A New Approach to Neuromodulation

Area of Science:

• Neurology
• Biomedical Engineering
• Neurosurgery

Background:

• Drug-resistant epilepsy (DRE) presents limited treatment options for non-surgical candidates.
• Current neuromodulation devices offer palliative benefits and have eligibility restrictions.
• Low intensity focused ultrasound (LIFUS) is an emerging noninvasive neuromodulation technology.

Purpose of the Study:

• To investigate the potential of LIFUS as a novel treatment for DRE.
• To evaluate the safety and efficacy of LIFUS in modulating neural tissue.
• To explore LIFUS as an alternative to existing palliative treatments for epilepsy.

Main Methods:

• Utilizing focused acoustic energy to noninvasively target specific brain regions.
• Applying LIFUS to modulate neural activity in animal models and human subjects.
• Conducting preclinical studies in epilepsy models and clinical trials in DRE patients.

Main Results:

• LIFUS demonstrated the ability to suppress seizures in animal models of epilepsy.
• Histopathological examination after sonication in epilepsy patients revealed no tissue damage.
• Ongoing trials are investigating LIFUS for hippocampal targeting in DRE.

Conclusions:

• LIFUS is a promising, incisionless, and radiation-free neuromodulation approach for epilepsy.
• If proven safe and effective, LIFUS could treat both cortical and deep brain structures.
• LIFUS is under extensive investigation for various neurological and psychiatric disorders, including epilepsy.
