The effect of hyperventilation on downbeat nystagmus in cerebellar disorders

Article abstract Hyperventilation can affect nystagmus in patients with vestibular disorders. However, the effects on nystagmus in patients with cerebellar disease have not been systematically studied. Using the magnetic field search coil technique, we studied the effects of hyperventilation on nystagmus in a series of cerebellar patients. In four of eight patients, hyperventilation produced an increase in the slow-phase velocity...
