AB Non-vestibular  dizziness  and  imbalance  can  be  very  frustrating  to  the  clinician,  because  the  symptoms  are  often  vague  and  the  vestibular  test  results  are  normal.  This  chapter  discusses  the  more  common  causes  of  these  disorders.  Disuse  disequilibrium  with  fear  of  fall,  the  most  common  cause  of  imbalance,  readily  responds  to  gait  and  balance  therapy.  Other  disorders  that  cause  imbalance  are  leukoaraiosis,  normal-pressure  hydrocephalus  (NPH),  progressive  supranuclear  palsy,  Parkinson's  disease,  large  fiber  peripheral  neuropathy,  and  cerebellar  ataxia.  Many  of  these  disorders  are  associated  with  disuse  disequilibrium  (or  deconditioning)  and,  therefore,  respond  to  physical  therapy  (PT)  to  a  certain  extent.  Some  individuals  with  these  disorders  do  not  have  disuse  disequilibrium,  because  they  are  very  active  or  are  too  incapacitated  to  perform  PT.  In  these  individuals,  one  must  concentrate  on  reducing  fall  risk  through  the  use  of  assistive  devices  and  education.  Finally,  we  discuss  a  group  of  disorders  that  are  best  described  as  dizziness  in  the  head  without  severe  imbalance  that  are  triggered  primarily  by  specific  situations.
