First Claim
Patent Images
1. A magnetic depolarizer system for the treatment of a neurological disorder, the system comprising:
- a readily portable magnetic depolarizer adapted for placement at a specific location onto the head of a patient who is subject to neurological events associated with a neurological disorder, the magnetic depolarizer having at least one electromagnetic coil that is adapted to provide a time-varying magnetic field pulsed on and off at a rate between approximately 0.1 and 10 Hz, the magnetic field having a peak intensity at some portion of the patient'"'"'s brain of at least 0.1 Tesla;
electrical circuitry connected to the magnetic depolarizer for providing an electrical current through the at least one electromagnetic coil, wherein the electrical circuitry is adapted to have an operating parameter corresponding to the frequency at which the time-varying magnetic field is pulsed on and off during use of the magnetic depolarizer by the patient preset before use by the patient of the system; and
a positioner for placing the magnetic depolarizer system onto the specific location of the head of the patient.

Abstract
A system for treating neurological conditions by low-frequency time varying electrical stimulation includes an electrical device for applying such low-frequency energy, in a range below approximately 10 Hz, to the patient'"'"'s brain tissue. An implantable embodiment applies direct electrical stimulation to electrodes implanted in or on the patient'"'"'s brain, while a non-invasive embodiment causes a magnetic field to induce electrical currents in the patient'"'"'s brain.
