Panic disorder patients show higher rates of seasonal mood changes and Seasonal Affective Disorder (SAD) than the general population. These findings suggest a potential link between panic disorder and SAD, possibly treatable with light therapy.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Chronobiology

Background:

  • Clinical observations noted increased anxiety and mood changes during winter in panic disorder patients.
  • Seasonal Affective Disorder (SAD) is a recognized mood disorder linked to seasonal variations.
  • Panic disorder is characterized by recurrent, unexpected panic attacks and anxiety.

Purpose of the Study:

  • To investigate the prevalence of seasonality and Seasonal Affective Disorder (SAD) in patients with panic disorder.
  • To explore potential seasonal variations in anxiety and panic attack frequency within this patient group.
  • To examine the possibility of a shared etiology between panic disorder and SAD.

Main Methods:

  • 133 patients diagnosed with panic disorder completed the Seasonal Pattern Assessment Questionnaire (SPAQ).

  • Global Seasonality Scores (GSS) were calculated to assess overall seasonal influence.
  • Prevalence of SAD and seasonal changes in panic attack frequency were analyzed.

    • Main Results:

    • Panic disorder patients exhibited significantly higher Global Seasonality Scores (GSS) compared to general population norms.
    • The prevalence of Seasonal Affective Disorder (SAD) was notably higher in this cohort.
    • Significant seasonal variations were observed in anxiety symptoms and the frequency of panic attacks.

    Conclusions:

    • Seasonality appears to be a more prevalent phenomenon in psychopathology than previously recognized.
    • Findings suggest a potential common underlying etiology for panic disorder and Seasonal Affective Disorder (SAD).
    • Light therapy may represent a viable treatment option for a subset of panic disorder patients experiencing seasonal exacerbations.
