Drug-resistant epilepsy represents roughly 40% of people with epilepsy. It is very challenging to stop seizures in this condition, and the treatment options are limited. This study aims to investigate a new treatment that involves using infra-red light. In animals, this treatment has shown promise as a possible way to reduce seizures, but it has not been tested in humans for this. The investigators are interested to know if it can reduce seizures, and how comfortable it is to be treated with this therapy.

Epilepsy affects 12 out of every 1000 people in the United States (1.2%). Of those, roughly 40% have drug-resistant epilepsy, meaning seizures do not stop despite good doses given with two different anti-seizure medications. Patients in this situation have several options (1) try additional medications (2) consider surgery to remove the part of the brain causing seizures, if possible (3) consider neuromodulation devices that change the brain activity using electricity in the brain (also a surgery) (4) try special diets such as the ketogenic diet which changes the fuel used by the brain by only eating certain foods. Despite these options, a large number of patients continue to have seizures. There is a great need for new treatments for drug resistant epilepsy.

The main purpose of this study is to determine if a new treatment is safe and well tolerated. Everyone in this study will receive the Red Light Therapy Hat which is investigational and is not approved by the FDA. The investigators do not know all the ways that this study treatment may affect people. This study is intended to hopefully help the participants, and the investigators hope the information from this study will help us develop a better treatment for drug resistant epilepsy in the future.

This particular investigational technology has been approved by the FDA for use in other diseases or conditions, but the investigators do not yet know if it is useful or safe as a treatment for drug resistant epilepsy.
