The Long Term Effects Of Bipolar Disorder

4. Causes

The cause of bipolar disorder is unknown; however, doctors believe it is due to a combination of environmental, genetic and biochemical factors. Chemical messengers in the brain called neurotransmitters associated with bipolar disorder include norepinephrine, serotonin, and dopamine, otherwise known as the “feel good” hormones. Several chromosomes have been linked to bipolar disorder, and research indicates that genetic factors may also increase the risk. Environmental factors such as life stress or emotional trauma may also play a role.
