SAD (or seasonal depression) usually causes serious mood problems during the less-sunlit months. It differs from classic depression only in its seasonal cycle; for most people, the symptoms are nonexistent during the spring and summer.
The specific cause of seasonal depression isn’t known. However, several factors are likely contributors—all in some way related to the reduced amount of sunlight in the winter:
Women tend to be diagnosed with SAD more often than men. Also, people who have a family history of depression are more prone to having SAD themselves.
To establish an accurate diagnosis for you, a healthcare provider may conduct physical and psychological exams, along with lab tests, to rule out other conditions that are similar to SAD.

Seasonal depression can be diagnosed if you’ve experienced at least two consecutive fall/winter periods with the following symptoms—which are absent during the spring and summer:
If you experience many of these symptoms, consult with your doctor or contact your program to get confidential assistance from a licensed mental health provider.
A provider may recommend light therapy (also known as phototherapy) for you. Phototherapy boxes use lamps that emit very bright fluorescent light that mimics natural light. This appears to cause a change in brain chemicals linked to mood. A common practice for home use is to sit a few feet away from the light box for at least 30 minutes each day.
If your symptoms are severe, or phototherapy has not helped, you may also benefit from treatment with antidepressant medications. Antidepressants such as Wellbutrin (bupropion), Prozac (fluoxetine) and Paxil (paroxetine) are often prescribed for treatment of seasonal depression.
Psychotherapy, or talk therapy with a mental health professional, can help you learn to cope better with seasonal depression. A common goal of treatment is to replace the negative thoughts and behaviors that SAD may be causing.
