Seasonal Affective Disorder can be treated with the usual anti-depressants that are used for other depressive disorders. Where the usual anti-depressants don't work, thyroid
hormones are also known to help. Photo-therapy (light therapy
) is also known to be effective, especially with winter onset depression
can help improve the depression in the long run.
A combination of these methods is usually employed, based on a person's symptoms. The treatment is usually customized for the individual needs.
Hope this helps.
