Depression

Sadness touches our lives at different times, but usually comes and goes. Depression, in contrast, often has enormous depth and staying power. It is more than a passing bout of "the blues." Depression can leave you feeling continuously burdened and can squash the joy you once got out of pleasurable activities.

When depression strikes, doctors usually probe what's going on in the mind and brain first. But it's also important to check what's going on in the body, since some medical problems are linked to mood disturbances. In fact, physical illnesses and medication side effects are behind up to 15% of all depression cases.

Depression isn't a one-size-fits-all illness. Instead, it can take many forms. Everyone's experience and treatment for depression is different. Effective treatments include talk therapy, medications, and exercise. Even bright light is used to treat a winter-onset depression known as seasonal affective disorder. Treatment can improve mood, strengthen connections with loved ones, and restore satisfaction in interests and hobbies.

New discoveries are helping improve our understanding of the biology of depression. These advances could pave the way for even more effective treatment with new drugs and devices. Better understanding of the genetics of depression could also usher in an era of personalized treatment.

In the northern and southern regions of the world, winter means shorter days and longer nights.

People with seasonal affective disorder, sometimes known as the winter blues, begin to experience sadness, depression, and fatigue in the late fall; symptoms fade away in the spring.
