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.
Claims12
A system for treating a neurological disorder in a human patient, the system comprising:
- an implantable control module including electronic circuitry, and
- a plurality of electrodes connected to the electronic circuitry, wherein the electrodes are adapted to be placed on the patient's brain, near the patient's brain, or in the patient's brain;
- wherein the electronic circuitry of the control module is adapted to stimulate the patient's brain with an electrical signal having a fundamental frequency below approximately 8 Hz and a minimum of energy content at frequencies above 8 Hz.
