AB Symptoms  and  signs  may  include  gait  impairment,  visual  blurring  due  to  nystagmus,  unclear  (“scanning”)  speech,  hand  incoordination,  and  tremor  with  movement.  Differential  diagnosis:  Unsteady  gait  associated  with  vertigo  from  vestibular  nerve  or  labyrinthine  disease  can  resemble  gait  instability  of  cerebellar  disease  but  produces  a  perception  of  movement,  dizziness,  or  light-headedness.  Sensory  disturbances  also  can  simulate  cerebellar  disease;  with  sensory  ataxia,  imbalance  dramatically  worsens  when  visual  input  is  removed  (Romberg  sign).  Bilateral  proximal  leg  weakness  also  can  rarely  mimic  cerebellar  ataxia.
