A 40-year-old female presents with regular episodes of irritability, insomnia, decreased appetite, and loss of weight that occur every summer. The symptoms usually remit by fall. She denies having any depressive symptoms outside these periods. What is the probable diagnosis and management strategy?
The patient's symptoms suggest Seasonal Affective Disorder (SAD), specifically the summer variant, which is characterized by episodes of depression during the summer months. While less common than winter SAD, it can be effectively managed. Treatment options include cognitive behavioral therapy (CBT), possibly medication management with antidepressants if symptoms are severe, and lifestyle modifications such as spending time in cooler, darker environments, and staying hydrated.
