Abstract:
1. An implantable device for detecting a patient's increased susceptibility to neurological events and triggering an action when a state of increased susceptibility is detected, the device comprising: a central processing unit provided with a therapy density analyzer, the therapy density analyzer further comprising: a therapy counter configured to count as a therapy event each time a therapy is delivered to the patient and to compare the number of therapy events to a predetermined number of therapy events; an interval counter configured to measure, if the number of therapy events reaches the predetermined number of therapy events, the time elapsed from the first counted therapy event up to the predetermined number of therapy events; and a density evaluator configured to compare the time elapsed from the first counted therapy event up to the predetermined number of therapy events to a predetermined time interval, and if elapsed time is less than the predetermined time interval, to provide a signal that is configured to initiate one or more actions to respond to the neurological events.
