AB Headache  occurs  in  all  age  groups  and  accounts  for  1%  to  2%  of  emergency  department  evaluations  and  up  to  4%  of  medical  office  visits;  the  causes  are  myriad  (Table  6-1).  Although  most  often  a  benign  condition  (especially  when  chronic  and  recurrent),  headache  of  new  onset  may  be  the  earliest  or  the  principal  manifestation  of  serious  systemic  or  intracranial  disease  and  therefore  requires  thorough  and  systematic  evaluation.
