title: Familial psychogenic blindness and headache: a case study.
abstract: BACKGROUND
  Amaurosis is an uncommon conversion phenomenon, which to our knowledge has never been reported in multiple family members.
  
  
  METHODS
  A man and his two adult children, all afflicted with periods of blindness and accompanying severe headaches for varying periods of time (days to years), were examined and extensively studied radiologically and with multiple laboratory tests.
  
  
  RESULTS
  In all three individuals, no evidence of organic disease was found; all three recovered to varying degrees, usually after suggestion.
  
  
  CONCLUSIONS
  Psychogenic amaurosis with headaches can simulate migraine; the mechanism for occurrence in a family is probably similar to that of mass hysteria.
