GOOD NEWS FOR PEOPLE WITH DEPRESSION Light treatment may work on non-seasonal depression too (not just on SAD).

Bright light therapy has been used effectively for seasonal affective disorder, the kind of depression that comes on at a specific time of the year - often the dark days of late autumn and winter - then lifts.

But a new study has found that it may now work to treat non-seasonal depression as well.

Researchers randomly assigned 122 patients with major depression, aged 19 to 60, to receive one of four treatments: 30 minutes of daily exposure to fluorescent light, 20mg of Prozac daily, both light and Prozac, and a dummy pill and exposure to an electric air purifier. The study, in JAMA Psychiatry, lasted eight weeks.

Using scales that quantify depression severity, the researchers found improvements in all four groups. The difference between Prozac alone and the placebo wasn't statistically significant, but light therapy alone was significantly better than the placebo, and light therapy with medication was the most effective treatment of all.
