What is the treatment for seasonal affective disorder?
In addition to being key in the prevention of seasonal affective disorder, regular exposure to light that is bright, particularly fluorescent lights, significantly improves depression in people with this disorder when it presents during the fall and winter. The light treatment is used daily in the morning and evening for best results. Temporarily changing locations to a climate that is characterized by bright light (such as the Caribbean) can achieve similar results. Light treatment has also been called phototherapy. Individuals who suffer from seasonal affective disorder will also likely benefit from increased social support during vulnerable times of the year.
Phototherapy is commercially available in the form of light boxes, which are used for approximately 30 minutes daily. The light required must be of sufficient brightness, approximately 25 times as bright as a normal living room light. Contrary to prior theories, the light does not need to be actual daylight from the sun. It seems that it is quantity, not necessarily quality of light that matters in the light therapy of seasonal affective disorder. The most common possible side effects associated with phototherapy include irritability, insomnia, headaches, and eyestrain.
Antidepressant medications, particularly those from the serotonin selective reuptake inhibitor family (SSRI) family, have been found effective treatment for seasonal affective disorder that presents during summer as well as that which tends to occur during the fall or winter. Examples of SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), and citalopram (Celexa). Common side effects for this class of medications include insomnia, nausea, diarrhea, and decreased sex drive or performance. As with any other mood disorder, psychotherapy tends to accentuate the effectiveness of medical treatment and therefore should be included in the approach to addressing this disorder. In individuals who are perhaps vulnerable to the development of bipolar disorder, either light therapy or antidepressant medication can cause a manic episode as a side effect.
Since stimulant medications like modafinil (Provigil) may be a helpful addition to other treatments for seasonal affective disorder, other stimulants like methylphenidate (Ritalin) may play a future role in addressing this disorder. Acupuncture may be a viable alternative intervention to antidepressant medications, particularly in pregnant women, for whom medications should be used with particular caution.
