About this trial
The goal of this clinical trial is to gauge whether overnight, non-invasive temporal interference (TI) stimulation aimed at the hippocampus can reduce abnormal brain activity linked to seizures and improve sleep in adults with drug-resistant temporal lobe epilepsy. The main questions are:
Does overnight TI stimulation lower seizure-related EEG activity during sleep?
Does overnight TI stimulation improve sleep quality and sleep patterns measured overnight in the lab?
Researchers will compare each participant's nights without stimulation to nights with active stimulation, and will also look at a night after stimulation ends to see whether any changes last.
Participants will:
Stay in-lab for six days for overnight sleep and EEG monitoring
Have one night of monitoring without stimulation
Receive TI stimulation during sleep for several nights
Have another night of monitoring without stimulation after the stimulation nights
Complete brief questionnaires and thinking/memory tasks before and after the stimulation nights
Be checked for side effects and comfort during the study and at follow-up
Eligibility criteria
Qualifiers
Age 18 - 70 years
