                        I am a mother of a child who is presently being tested for vertical nystagmus.  I am having a hard time understanding it.  She is 13 months old.  They are doing an MRI (brain scan and brain stem scan) in a couple of weeks.  Is this how you were diagnosed?  Any information you may have about this disorder is very much appreciated.  Thank You!
