A method for limiting patient-initiated electrical signal therapy to a cranial nerve of a patient is provided. An electrical signal therapy limit is selected from the group consisting of; a maximum number of patient-initiated signals, a maximum dose of electrical signals, a maximum duration of electrical signal, a maximum rate of change of the number of patient-initiated signals, a maximum rate of change of the dose of electrical signals, and a maximum rate of change of the duration of the electrical signals all per unit of time. If the electrical signal therapy limit is exceeded a therapy is delivered to the cranial nerve selected from the group consisting of; providing therapy, providing reduced therapy, providing enhanced therapy, inhibiting therapy, providing background therapy, and inhibiting background therapy.
