Medical Edge: Persistent symptoms of depression in winter could be SAD

DEAR MAYO CLINIC: I’ve been diagnosed with clinical depression. I’m taking duloxetine (Cymbalta), which helps. But I always feel more blue and have a hard time finding the energy to do my normal activities when fall and winter come. My neurologist thinks I should see a therapist, but talking about depression makes me feel worse. Is there anything else I can do?

ANSWER: Because your symptoms get worse as the seasons change, you could have seasonal affective disorder, or SAD, a form of clinical depression. If so, several treatment options are available that may help.

SAD is a type of depression that affects people during the fall and winter months. The lower levels of sunlight in the winter and fall may upset your sleep patterns and lead to feelings of depression. When combined, these factors may lead to SAD.

SAD is different from non-seasonal depression in several unique ways, particularly in its timing. SAD is more than just feeling blue as the days get shorter or having the doldrums during January. Instead, it involves persistent, pervasive symptoms of depression during wintertime.

Symptoms may include feeling sad or angry; irritability; lack of interest in activities you usually enjoy; difficulty concentrating; lack of energy; and, in some cases, feeling that life isn’t worth living or having suicidal thoughts.

People with SAD also usually feel the need to sleep considerably more than usual. That’s not always the case with those who have depression that is not linked to seasonal changes. SAD generally causes people to want to eat more, too, and they often gain weight. Carbohydrate cravings are particularly common. Individuals with depression that is not seasonal typically do not have an increase in appetite and weight loss is more common.

SAD symptoms may get worse as winter progresses. They typically fade as daylight increases during spring.
