350 million people are affected with depression.
But what goes on inside the system of someone who’s depressed? Can we explain these intense feelings of sadness biologically? In the past, researchers believed that depression is all about a chemical imbalance in the brain; that a lack of serotonin contributes much to the condition of a person who is depressed. But newer findings point to other causes. In fact, biological aspects are now being discussed when talking about this serious illness. Indeed the growth of brain cells and cell connections play a more important role in depression.
