AB  - Ataxia  is  defined  as  the  inability  to  generate  a  normal  voluntary  movement  trajectory  that  cannot  be  attributed  to  weakness  or  involuntary  muscle  activity.1  The  word  derives  from  Greek  and  means  without  order,  referring  to  disorganized,  poorly  coordinated,  or  clumsy  movments.2  The  disorder  may  be  caused  by  dysfunction  of  the  cerebellum  or  its  immediate  projections,  and  is  traditionally  referred  to  as  cerebellar  ataxia.  In  such  cases,  ataxia  may  involve  appendicular  (e.g.,  limb)  or  axial  (e.g.,  truncal)  control,  often  affecting  balance  and  gait.  Cerebellar  ataxia  is  estimated  to  affect  26  in  100,000  children  worldwide.3  Injuries  to  the  proprioceptive  system  may  also  present  with  clumsy,  disorganized  movements,  known  as  sensory  ataxia.  Finally,  vestibular  injury  may  affect  posture  and  balance,  which  much  be  distinguished  from  ataxia.  This  chapter  focuses  on  symptoms,  signs,  and  etiologies  of  cerebellar  ataxia,  with  an  emphasis  on  infectious  and  para/postinfectious  causes.
