AB  - Headache  is  a  nearly  universal  symptom.  As  an  example  of  the  prevalence  of  headache,  a  study  of  410  patients  who  had  visited  a  primary  care  internal  medicine  practice  found  that  headache  was  the  fourth  most  common  symptom  and  was  exceeded  only  by  fatigue,  back  pain,  and  dyspnea.1  In  an  early  study  of  over  1  million  unselected  individuals  from  the  general  population,  headache  was  the  single  most  common  current  symptom  and  was  reported  by  39%  of  men  and  56%  of  women.2  As  physicians,  nearly  all  of  us  have  had  personal  experience  with  headache  and  can  understand  the  headache  descriptions  that  we  hear  from  our  patients.  Chapter  17  elegantly  details  the  prevalence  of  this  common  symptom  and  of  common  primary  headache  syndromes.  Primary  headaches  are  those  without  a  pathologic  basis.3–5  These  are  benign  recurring  headaches  of  unknown  cause.  The  most  common  primary  headache  syndromes  are  migraine,  tension-type,  and  cluster  headache.  Secondary  headaches  are  the  result  of  an  underlying  pathologic  cause.
