摘要： A method for detecting an approaching seizure is disclosed. The method includes receiving an analog neurosignal from an electrode, comparing the analog neurosignal with a predetermined amplitude threshold to generate a plurality of digital transitions corresponding to the analog neurosignal transitioning from a first level below the predetermined amplitude threshold to a second level above the predetermined amplitude threshold, generating a plurality of comparator signals, each comparator signal of the plurality of comparator signals corresponding to a comparison of a length of time between a pair of digital transitions of the plurality of digital transitions and a predetermined temporal threshold, and generating a seizure detection signal if at least two of the comparator signals of the plurality of comparator signals are enabled. A seizure detection system for detecting an approaching seizure is also disclosed.
