AB  - Dizziness  is  an  imprecise  symptom  used  to  describe  a  variety  of  sensations  that  include  vertigo,  light-headedness,  faintness,  and  imbalance.  When  used  to  describe  a  sense  of  spinning  or  other  motion,  dizziness  is  designated  as  vertigo.  Vertigo  may  be  physiologic,  occurring  during  or  after  a  sustained  head  rotation,  or  it  may  be  pathologic,  due  to  vestibular  dysfunction.  The  term  light-headedness  is  commonly  applied  to  presyncopal  sensations  due  to  brain  hypoperfusion  but  also  may  refer  to  disequilibrium  and  imbalance.  A  challenge  to  diagnosis  is  that  patients  often  have  difficulty  distinguishing  among  these  various  symptoms,  and  the  words  they  choose  do  not  reliably  indicate  the  underlying  etiology.
