Abstract
Techniques for warning a patient of a possible onset of a seizure using a sensor, a signal generator and at least one implantable electrode. The electrodes are positioned to stimulate the spinal cord or under the skin. The sensor senses a parameter of the body indicative of the possible onset of a seizure. The sensor generates a sensing signal which is processed and an algorithm is utilized to determine whether the sensing signal shows a pattern indicative of a possible seizure onset. If such a pattern is recognized, the signal generator provides electrical stimulation via electrodes to generate a sensory stimulus to the body. The stimulation may provide visual, aural or touch stimulus to the patient. The patient is thereby alerted to the possibility of a seizure onset and may take appropriate action.
