Seasonal Affective Disorder Seasonal Affective Disorder (SAD) is a type of depression that occurs at the same time every year, usually starting in the fall and may continue through the winter months. Prevalence increases with latitude. For example, in Florida 1.4 percent of the population may experience symptoms, whereas, in New Hampshire, the number rises to 9.7 percent. The average age of onset is 23. Incidence decreases with age. Symptoms: Fall onset SAD - Hopelessness, anxiety, oversleeping, heavy feeling in arms and legs, craving foods high in carbs, weight gain, social withdrawal. Summer onset – Weight loss, insomnia, irritability Causes: In some people, the body’s biological clock can be disrupted due to reduced sunlight and hours of daylight. This causes a decrease in Serotonin levels, which can influence mood. Also, a family history of depression may be a factor. Treatment: The treatment of choice is Light Therapy and/or Medication Management.
Warning! Both treatments can trigger a manic episode in people with bipolar. Lifestyle Measures can be effective if symptoms are mild to moderate. For example, brighten the home environment (open blinds, sit closer to windows, add skylights, trim tree branches); get outdoors within 2 hours of getting up in the morning (take a long walk, sit on a bench and soak up the sun, have lunch in the park) and exercise regularly.
