It is commonly known that MS can impact mood and can cause an increased risk for developing depression and anxiety which MSAA detailed in the Winter/Spring 2014 issue of The Motivator. However, you may be unfamiliar with another condition – Seasonal Affective Disorder (SAD) – which may be something to pay attention to as the seasons change.

SAD is a type of depression which is hallmarked by its “seasonality” generally beginning in the fall and lasting through the winter months. SAD typically tends to creep up as the daylight hours get shorter and the weather gets cooler and the impacts on mood may become more severe as the season goes on.  Like other forms of depression, individuals who experience SAD may experience low energy (fatigue), may lose enjoyment in activities they once enjoyed, may experience changes in eating or sleeping habits, may have persistent sad or depressed thoughts, and may even think of engaging in self-harm. As with other forms of depression, individuals with SAD may benefit from the use of medications and/or talk therapy to help address this issue. One major difference with teasing out SAD from other forms of depression is that individuals with SAD may also benefit from using “phototherapy” or specialized light therapy; a person may even be assigned a specific amount time in their day to sit under the specialized light or lamp to help improve their symptoms.

If you have noticed that the fall and winter seasons tend to impact your mood, or if you have noticed a lower overall mood, please discuss the issue with your treating physician…sometimes just shedding some “light” on a situation can make a world of difference.
