Abstract
Method and apparatus for treating and controlling migraine by selectively applying a predetermined electrical signal to the patient's vagus nerve for stimulation thereof to alleviate the migraine attack. The signal is a pulse waveform having parameters programmed to desynchronize the patient's EEG if paroxysmal activity is detected in the EEG, or to synchronize the EEG if low voltage fast wave activity is detected. Alternatively, the application of the stimulating signal to the vagus nerve may be initiated manually by the patient upon recognition of the onset of a migraine attack. The neurostimulator device implanted in the patient to generate the appropriate signal has a power down circuit to conserve battery power between migraine episodes.
