1. A method for treating a patient for anxiety, depression, and insomnia, the method comprising:
(a) generating a stimulation current conveyed to the patient for a treatment duration via the steps of:
generating a carrier waveform, the carrier waveform being an alternating current having a duty cycle ratio and a current amplitude ratio, the duty cycle ratio and the 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; and
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, the stimulation current envelope defining a first series of pulses occurring at a first frequency and a second series of pulses occurring at a second frequency, the first series of pulses occurring at a first frequency that does not substantially vary for the entire treatment duration, the second series of pulses occurring at a second frequency that varies during the treatment duration, the second series of pulses occur at a frequency between 4 Hz and 100 Hz; and
(b) conveying the stimulation current to the frontal cortex region of the brain of the patient.
