Abstract
Seizure prediction systems and methods include measuring impedance and a potential within a brain of a patient to determine whether the brain is in a state indicative of a possibility of seizure. In some embodiments, at least one of the measured impedance or the measured potential may be used as a primary indication of the brain state indicative of a possibility of seizure. In one embodiment, if one of the measured impedance or the measured potential indicates a seizure, the other measurement (impedance or potential) may be used to validate whether the brain is in the state indicative of the possibility of seizure.

27. A system comprising:
-
one or more electrodes implantable in a brain of a patient; a sensing module configured to measure a potential of the brain and deliver an electrical stimulus to the brain via at least some of the electrodes to measure an impedance of the brain; and a processor coupled to the sensing module, wherein the processor receives impedance measurements and potential measurements from the sensing module and determines whether the brain is in a state indicative of a possibility of seizure based on the measured impedance and measured potential. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
