1. An electrical stimulation lead assembly, comprising:

  • at least one lead body having a distal end portion, a proximal end portion, and a longitudinal length;

    a plurality of electrodes disposed along the distal end portion of the at least one lead body;

    a plurality of terminals disposed along the proximal end portion of the at least one lead body;

    a plurality of stimulation conductors coupling the plurality of terminals to the plurality of electrodes; and

    a cerebrospinal-fluid-pulsation detection assembly (“

    CSF-pulsation detection assembly”

    ) comprisingat least one sensor disposed along the distal end portion of the at least one lead body, the at least one sensor configured and arranged for detecting pulses of cerebrospinal fluid within a subarachnoid space of a patient and transforming the detected pulses of cerebrospinal fluid into sensor signals,a sensor processor for receiving the sensor signals from the at least one sensor, processing the received sensor signals to generate cerebrospinal-fluid pulsation data (“

    CSF-pulsation data”

    ) comprising at least one of amplitude, duration, or rate of cerebrospinal-fluid pulses, and estimating at least one patient blood-flow condition based on the CSF-pulsation data, andat least one sensor control pathway coupling the at least one sensor to the sensor processor.
