The seasons and the leaves aren't the only things changing this fall.
Many people notice a change in their moods as well.
Such emotions may be due to a disorder called Seasonal Affective Disorder. Ten to 25 million Americans suffer from this form of depression that occurs when lack of sunlight affects levels of melatonin in the body, according to mayohealth.org. Women are four times more likely to be diagnosed with SAD than men, says George Soncrant, a psychiatrist in Wisconsin. Sixty-ninety percent of sufferers are women and it's more common in young people, and seven times more likely to occur in Washington than in Florida, putting Oregon teens at a greater risk. That's why we know about more cases in women and young people.
