Bipolar Disorder and Manic Depressive Illness

Studies show that some depressive disorders—bipolar disorder in particular—are caused by chemical imbalances in the brain. Your brain produces and uses chemicals called neurotransmitters, which send messages through your nerve cells to your entire body.

People experiencing mania usually have too many neurotransmitters being produced, whereas people in a depressed cycle often have too few. Such excesses or deficiencies upset the communication between your brain and your body Although much about neuro-transmitters is still being researched by scientists, once an imbalance is detected, doctors are often able to readjust levels with the use of medicine.
