Jerk nystagmus : The four most frequent identifiable causes of downbeat nystagmus are cervico-medullary junction anomalies (Chiari malformation), cerebellar degenerations, multiple sclerosis, and vertebrobasilar infarction. Medications and alcohol are other relatively common causes. Uncommon causes include B12 deficiency and familial. An MRI should be done if you have not had one yet. Treatment is dalfampridine.
