Low frequency non-invasive sensorial stimulation for seizure control

Abstract

Example apparatus and methods reduce epileptic seizures in a human patient by non-invasively providing low frequency (e.g., 1-10 Hz) audio stimuli coordinated with low frequency (e.g., 1-10 Hz) visual stimuli to the patient. The signals are provided non-invasively through the eyes and ears. The audio stimuli and visual stimuli may be selected or coordinated based on a state (e.g., hyperexcitability, imminent epileptic seizure, epileptic seizure in progress, REM sleep) determined from an EEG signal acquired from the patient. Apparatus for delivering the audio stimuli and visual stimuli may be incorporated into a single wearable apparatus (e.g., glasses with earphones, hat, headband). The single wearable apparatus may also provide noise cancellation and visual stimulus diminution. The audio stimuli may be incorporated into music or random background noise.
