An anesthesiologist on staff at a hospital went to see a fellow doctor as a patient. He was having brief lapses of consciousness related to complex partial seizures, a form of epilepsy that had gone unrecognized during his residency. He admitted to having at least one seizure in the OR that was so brief that no one observed it. The condition was treatable but left the second doctor uncertain about whether to uphold the privacy of the doctor-patient relationship or to inform the hospital staff.
