What is the Code for Seasonal Affective Disorder?

The code for seasonal affective disorder is basically shorthand of SAD. "Seasonal Affective Disorder (SAD) is a problem which, if I remember correctly, the experts claim is caused by reduced sunlight caused by the shorter days starting in fall, winter, and possibly extending into spring. It supposedly affects some people, probably a small percentage of the population, but is often described in the news as a simple fact, implying it happens to everyone." You may have seen some people who have been affected by it. It is usually very minor and can be cured with a small amount of therapy. Make sure to get it checked out.
