Understanding Summer Seasonal Affective Disorder (SAD)
Overview of Seasonal Affective Disorder (SAD)
Seasonal Affective Disorder (SAD) is a type of recurrent major depressive disorder that follows a seasonal pattern. While it is most commonly associated with winter, where individuals experience depressive episodes during the fall and winter months, there is also a less common variant known as summer SAD, where depressive episodes occur during the spring and summer 146.
Symptoms of Summer SAD
The symptoms of summer SAD differ from those of winter SAD. Individuals with summer SAD often experience decreased sleep (insomnia) and decreased appetite, which contrasts with the hypersomnia and increased appetite seen in winter SAD 59. Other symptoms include a sad mood and low energy levels, similar to other forms of depression .
Prevalence and Risk Factors
Summer SAD is less common than its winter counterpart. It affects a smaller percentage of the population, with winter SAD affecting approximately 2-5% of people in temperate climates . Those most at risk for any form of SAD include younger individuals, females, those living far from the equator, and individuals with a family history of depression, bipolar disorder, or SAD .
Diagnostic Criteria
The diagnosis of SAD, including summer SAD, often involves the use of the Seasonal Pattern Assessment Questionnaire (SPAQ) and criteria from the DSM-IV, which emphasize the importance of full remission during the non-depressive season 34. The DSM-IV criteria are particularly stringent and help in distinguishing SAD from other forms of depression .
Treatment Approaches
While bright light therapy is the treatment of choice for winter SAD, its efficacy for summer SAD is less clear. Treatment for summer SAD may include antidepressant medications, counseling, and other psychopharmacological treatments 24. The pathophysiological mechanisms underlying SAD, including neurotransmitter dysfunctions and circadian rhythm disruptions, are still being studied, and these insights may guide future treatment options .
Conclusion
Summer SAD, though less common than winter SAD, presents unique challenges and symptoms. Understanding its distinct characteristics, prevalence, and treatment options is crucial for effective management. Ongoing research into the pathophysiology of SAD will continue to enhance our understanding and treatment of this seasonal disorder.
