Abstract
Transcranial electrostimulation systems and methods are contemplated in which a high current level, charge balanced alternating current electrical signal is generated for delivery to the occipital region of a patient's brain. By stimulating the brain with a charged balanced stimulation current with a stimulation current envelope defining one or more series of pulses at particular frequencies and durations designed to evoke metabolic response in the neurons, significant improvements in efficacy and reductions in patient discomfort may be achieved relative to earlier methods of transcranial electrical stimulation, especially those in which result in a resultant rectified direct current component being administered to the patient. Further advantages, especially in promoting neural entrainment, may be realized as well via utilizing multiple series of pulses at different frequencies, and via the dynamic adjustment of the stimulation waveform via incorporation of feedback signals in order to maintain charge balance in real-time.
