AB  - Headaches  are  estimated  to  affect  over  90%  of  the  general  population  at  some  time  in  their  lives1  and  may  be  encountered  by  physicians  in  a  wide  variety  of  clinical  settings.  The  overwhelming  majority  of  recurrent  headaches  occur  in  the  context  of  what  are  known  as  primary  headache  disorders,  in  which  no  identifiable  underlying  cause  can  be  found.  Some  headaches,  however,  classified  as  secondary  headache  disorders,  are  symptomatic  of  an  underlying  abnormality  that  may  include  anything  from  transient  viral  illness,  to  intracranial  tumor,  aneurysm,  or  drug  withdrawal  (for  differential  diagnosis  of  secondary  headache  disorder,  see  Cutrer2).  Prevalence  studies  indicate  that  a  benign  process,  such  as  a  mild  febrile  illness  or  alcohol  withdrawal,  usually  causes  secondary  headaches  and  that  the  lifetime  prevalence  of  headache  resulting  from  more  ominous  intracranial  structural  lesions  is  less  than  2%.3
