A vestibular implant system is described which includes an implantable vestibular stimulator providing a vestibular stimulation signal to electrically stimulate target neural tissue for vestibular sensation by a patient. A patient warning alarm process alters the stimulation signal when a given alarm condition occurs to change the vestibular sensation of the patient thereby warning the patient of the alarm condition.
