title: New daily persistent headache and panic disorder.
abstract: BACKGROUND
  New daily persistent headache (NDPH) is a primary chronic daily headache that is generally considered to be difficult to treat. Migraine has been linked to comorbid psychiatric conditions, mainly mood and anxiety disorders, but NDPH has never been linked to psychiatric conditions, and never studied extensively for such an association.
  
  
  METHODS
  We report nine cases (six women and three men) of patients diagnosed with NDPH and panic disorder who were treated for both conditions. Six of them (66%) had good or excellent responses.
  
  
  CONCLUSIONS
  The spectrum of anxiety disorders, particularly panic disorder, should be considered in NDPH patients. Simultaneous treatment of both disorders may lead to good outcomes.
