Depression after traumatic brain injury.

Antidepressant medications work by rebalancing the natural chemicals (neurotransmitters) in the brain to improve mood, energy, concentration, sleep, appetite, and anxiety. It is important to know that antidepressants are not addictive and usually do not need to be taken forever. Since each person’s situation is unique, always plan your antidepressant schedule with a doctor. There are many different types or “classes” of antidepressant medications. Studies have shown that some classes may work better than others.
