Learning from our treatment failures.

Barton and Blanchard's report that multicomponent behavioral treatment fails to modify chronic daily headaches is discussed with reference to the effectiveness of behavioral and drug treatments for chronic tension-type headache, the distinction between chronic tension-type headache and chronic migraine, and the psychophysiology of episodic vs. persistent pain (K. A. Barton & E. B. Blanchard, 2001). It is suggested that the treatment of chronic daily headache can be improved through research on the benefits of combined behavioral and drug therapy, the psychophysiology of persistent pain, and methods of preventing episodic headaches from evolving to daily headaches.
