From the Guidelines

Seasonal Affective Disorder (SAD) treatment options include Bright Light Therapy and Psychotherapy.

Treatment Options

  • Bright Light Therapy: The updated guideline recommends bright light therapy for persons with mild to moderate MDD, regardless of seasonal pattern or seasonal component 1. This can be used in combination with other treatments or as monotherapy for treatment of MDD.
  • Psychotherapy: Six forms of psychotherapy are recommended for initial treatment of depression, including acceptance and commitment therapy, behavioral therapy/behavioral activation, CBT, interpersonal psychotherapy, mindfulness-based cognitive therapy, and problem-solving therapy 1.

Important Considerations

  • Factors such as patient preferences, past experience with treatment, and provider training should be considered when selecting specific approaches 1.
  • The benefits of bright light therapy outweighed any potential harm, which led to the recommendation, despite low confidence in the evidence due to notable limitations 1.

Effectiveness of Treatment Options
