The present disclosure provides neurostimulation systems and methods. A neurostimulation system includes at least one anode, at least one cathode, the at least one anode and the at least one cathode configured to apply electrical stimulation to a patient, and a controller electrically coupled to the at least one anode and the at least one cathode, the controller configured to determine when one of the at least one anode and the at least one cathode fails, measure, in response to the determination, a quantity indicative of a charge density of the applied electrical stimulation, compare the measured quantity to a predetermined limit, and perform at least one action when the measured quantity exceeds the predetermined limit.
