1. A method for using an implantable device to treat a neurological disorder in a human patient, comprising:
- detecting a neurological event by configuring a plurality of channels in the device to detect a neurological event in a continuously monitored electrographic signal based upon a plurality of detection parameters;
adapting a form of stimulation to treat the neurological event by configuring at least one channel in the device to extract at least one adaptive stimulation parameter from at least one measurement, wherein the at least one adaptive stimulation parameter determines a type of therapy to be delivered to the patient, a plurality of stimulation parameters with which the therapy will be characterizable, and a timing according to which the therapy will be delivered;
selecting the type of therapy from a plurality of possible therapies based at least in part on the at least one adaptive stimulation parameter;
selecting the stimulation parameters based at least in part on the at least one adaptive stimulation parameter;
determining the timing of the therapy delivery based on the at least one adaptive stimulation parameter; and
delivering the selected therapy type according to the stimulation parameters and synchronized with the detected event in accordance with the timing.

Abstract
An implantable neurostimulator system adapted to provide therapy for various neurological disorders is capable of varying therapy delivery strategies based on the context, physiological or otherwise, into which the therapy is to be delivered. Responsive and scheduled therapies can be varied depending on various sensor measurements, calculations, inferences, and device states (including elapsed times and times of day) to deliver an appropriate course of therapy under the circumstances.
