Depression


What happens in the brain when someone is Depressed?

Depression involves the brain's delicate chemistry — specifically, it involves chemicals called neurotransmitters. These chemicals help send messages between nerve cells in the brain. Certain neurotransmitters regulate mood, and if they run low, people can become depressed, anxious, and stressed. Stress also can affect the balance of neurotransmitters and lead to depression.
Sometimes, a person may experience depression without being able to point to any particular sad or stressful event. People who have a genetic predisposition to depression may be more prone to the imbalance of neurotransmitter activity that is part of depression.
Medications that doctors use to treat depression work by helping to restore the proper balance of neurotransmitters
