title: Photosensitivity in panic disorder.
abstract: BACKGROUND
  The objective of this study is to evaluate abnormal light-related behavior in patients with panic disorder (PD).
  
  
  METHODS
  We administered the Photosensitivity Assessment Questionnaire to 30 subjects with PD and to 40 healthy subjects. The Photosensitivity Assessment Questionnaire is a self-report questionnaire that evaluates two dimensions of photosensitivity: photophilia and photophobia.
  
  
  RESULTS
  Compared to healthy controls, PD subjects reported significantly higher scores on the photophobia (P<.003) and significantly lower scores on the photophilia (P<.001) questions.
  
  
  CONCLUSIONS
  Subjects with PD indicated that they tolerate and seek light to a significantly lower degree than normal controls.
