What you need to know about Seasonal Affective Disorder (SAD)
Seasonal Affective Disorder (SAD), often called Seasonal Depression, is as it sounds, depression that follows a seasonal pattern. This seasonal mood disorder is not fully understood, but there are a few theories and it is known that people with other mood disorders (bipolar or depression) are more at risk. A late-fall/early-winter onset is common as the levels of light start to decrease, but there is also summer-patterned SAD that is lesser-known.
Many people are able to self-diagnosis seasonal depression, but it's always important to talk to a doctor when you experience any changes to your mood.
Don't let SAD bully you. The best way to treat seasonal depression is to be proactive.
What is seasonal depression?
Seasonal affective disorder, or seasonal depression, is a type of depression that follows a seasonal pattern. This means that mood might change with the seasons. Many people with depression experience changes in their circadian rhythm, such as sleeping too little or too much, but with seasonal depression, it is possible that the change in the amount of light could affect the body's natural circadian rhythm leading to depression. That being said, those previously diagnosed with depression or bipolar disorder are more likely to feel the changes with the seasons. Light has a few known influences in the brain, including serotonin and melatonin release, and even though SAD is not fully understood, trying to regulate these influences with light or medication can significantly reduce symptoms.
What are the symptoms of SAD?
Most of the symptoms of SAD are consistent with that of major depression, but there are a few specific symptoms for winter and a few for summer-patterned depression (severity and combination of symptoms is specific to the individual (you do not need to express all symptoms to be diagnosed with SAD, depression, or bipolar disorder).
