AB Vertigo  is  a  perception  of  movement  when  none  exists  that  results  from  a  mismatch  between  the  visual,  vestibular,  and  proprioceptive  sensory  systems.  Symptoms  of  vertigo  are  classically  described  by  patients  as  a  sensation  that  “the  room  is  spinning,”  but  can  also  include  atypical  sensations  of  other  types  of  movement.  Vertigo  is  classified  as  peripheral  or  central  (Table  144-1).  Peripheral  vertigo  (involving  the  vestibular  apparatus  and  eighth  cranial  nerve)  usually  has  a  sudden  onset  with  intense  symptoms  that  include  nausea,  vomiting,  intolerance  of  head  movement,  and  diaphoresis.  Central  vertigo  (involving  central  structures  such  as  the  brainstem  or  cerebellum)  can  present  either  abruptly  or  gradually,  but  usually  is  characterized  by  less  severe  symptoms  that  are  not  well  characterized  by  patients.  Clinicians  can  work  to  discriminate  between  these  two  types  of  vertigo  during  a  care  encounter  in  the  Emergency  Department  (ED)  while  recognizing  that  some  overlap  may  exist  between  these  two  types  of  vertigo.
