TRANSCRANIAL ALTERNATING CURRENT DYNAMIC FREQUENCY STIMULATION METHOD FOR ANXIETY, DEPRESSION, AND INSOMNIA (ADI)

A method for treating a patient for anxiety, depression, and insomnia. The method includes generating a stimulation conveyed to the patient for a treatment duration current via generating a carrier waveform being an alternating current having a duty cycle ratio and a current amplitude ratio being selected such that each respective integration of the current amplitude between successive time instances at which the carrier waveform alternates polarity is substantially equivalent. The method further includes generating a stimulation current from the carrier waveform via amplitude modulating the carrier waveform. The extremes of the stimulation current defining a stimulation current envelope defining first and second series of pulses. The first series of pulses occurring at a first frequency that does not substantially vary for the entire treatment duration, and the second series of pulses occurring at a second frequency that varies during the treatment duration.
