title: Diagnostic delays and mis-management in cluster headache.
abstract: OBJECTIVE
  Cluster headache is a stereotyped form of primary headache that while common in terms of neurologic illnesses is much less common as a cause of disabling headache than migraine.
  
  
  METHODS
  We directly interviewed 230 patients with cluster headache. National support groups contributed 76% and 24% came from the National Hospital for Neurology and Neurosurgery Headache Clinic.
  
  
  RESULTS
  Seventy-two percent were men and 28% women, giving a male to female (M:F) ratio of 2.5:1. Episodic cluster headache (ECH) was recorded in 79% while 21% had chronic cluster headache (CCH). The mean time to diagnosis has dropped from 22 years in the 1960s to 2.6 years in the 1990s, although the mean number of GPs seen before a diagnosis was made remains at three.
  
  
  CONCLUSIONS
  While there has been improvement in the time to diagnosis for cluster headache, a number of physicians will be consulted, and better education is likely to reduce the overall patient suffering.
