As winter approaches, some of us may experience the “winter blues” – feeling sad from shortening days, climbing into bed earlier and resenting waking up on dark mornings.
That’s different than Seasonal Affective Disorder (SAD), a term used to describe a type of depression that follows a seasonal pattern.
The most common form of SAD occurs in winter, although some people do experience symptoms during spring and summer. And while SAD is often talked about in terms of adults, children and adolescents are not necessarily immune.
Who is at risk for SAD?
SAD usually develops in a person's early 20s but can occur in older children and teens. The risk for the disorder decreases as you get older. SAD is diagnosed most often in young women, but men who have SAD may suffer more severe symptoms. People with a family history of SAD or those who live in northern latitudes where daylight hours during winter are shorter are at a higher risk for developing SAD.
Symptoms of SAD
When experiencing SAD, a person may
withdraw socially and no longer enjoy things that used to be fun. It's as if a person's batteries have just run down.
crave comfort foods, including simple carbs such as pasta, breads, and sugar. With excess unhealthy calories and a lack of fresh fruits, vegetables, and whole grains, fatigue often sets in, leading to increased sleepiness and weight gain.
feel anxious, irritable, have trouble sleeping, or decreased appetite. These symptoms are more common with the spring/summer form of SAD.
No Known Cause
Researchers have not determined what causes SAD. There is some evidence pointing to a disruption of a person's "circadian rhythm" — the body's natural cycle of sleeping and waking. As the days shorten, the decreasing amount of light can throw off the body's natural clock, triggering depression. Sunlight also plays a role in the brain's production of melatonin and serotonin. During winter, your body produces more melatonin (which encourages sleep) and less serotonin (which fights depression). Researchers do not know why some people are more susceptible to SAD than others.
In general, SAD is a better-recognized disorder in adults because so many children's mental health disorders emerge over time. Diagnosing SAD in a child is not easy, because determining the pattern of depression takes time. A doctor will typically attempt to determine whether a child is suffering from depression or anxiety first, then look at the pattern over time. The diagnosis of SAD is made only if a person meets criteria for a diagnosis of depression and if a seasonal pattern of symptoms has been present for at least 2 years.
In order to diagnose SAD, doctors need to perform a medical exam to rule out other possible causes of the symptoms. They may also administer questionnaires to determine mood and look for seasonal patterns.
Working through it together
Whether noticing symptoms of SAD in yourself or in your child, take it seriously. Treating this disorder early and diligently can turn the dark days of winter into a pleasant time of togetherness for your family.
