Causes of Depression


The exact cause of depression isn't clear. No one is sure why some people get depressed and others don't. Sometimes depression seems to happen because of a stressful event. Sometimes it seems to happen for no reason at all.
Genes could play a role. People whose blood relatives have had depression are more likely to have it, too. However, not everyone who has a relative with depression is going to develop it.
Today, it's widely understood that depression is a serious medical condition. Scientists believe that it could be linked with an imbalance of a chemical in the brain called serotonin. If this imbalance happens, it can affect the way people feel.
