What causes a chemical imbalance in the brain?

Chemical imbalances happen due to diseases, injuries, aging, chronic stress and poor nutrition. When most people talk of chemical imbalance, especially doctors and researchers, they’re referring to an imbalance of neurotransmitters or chemical messengers of the brain.

What causes depression neurotransmitters?

How do I make my brain chemicals happy?

Serotonin Exposure to bright light, especially sunshine, is one way to increase serotonin. Exercise and happy thoughts also stimulate production of this chemical. Some research has found that a higher intake of tryptophan-heavy foods, relative to other foods in the diet, may do the trick as well.

Is there a connection between brain chemistry and depressive disorders?

Depression is also a multi-faceted condition, but having an awareness of the brain chemistry component can be useful for medical and mental health professionals, researchers, and many people who have depression.
