Eight-and-a-Half Syndrome

Eight-and-a-Half Syndrome

The combination of a facial (VII) nerve palsy with a one-and-a-half syndrome due to a pontine lesion has been labeled the eight-and-a-half syndrome. Patients may develop oculopalatal myoclonus months to years after the onset of the ocular motility problem.
