Causes and Effects of Bipolar Disorder
Scientists believe that there is no single cause of bipolar disorder; however, there are factors that contribute to and increase the risk for it, such as:
- Brain structure and functioning
- Genetics
- Family history
Through neuroimaging, medical experts are able to scan the brain in order to learn about mental disorders. While the tests cannot diagnose a mental disorder, they can rule out medical illnesses that may be contributing to a person’s mental well-being. The images are mostly utilized to compare a healthy brain with a brain that is suffering from a disorder; they are able to show brain damage as well as brain development.
In 2010, researchers found a gene that was present among 62 percent of people who suffer from a mood disorder. This research does not prove that bipolar disorder is 100 percent genetic; however, it does prove that disorders are increased due to genetics.
According to the National Institute of Mental Health, “some research suggests that people with certain genes are more likely to develop bipolar disorders than others”. Although it is not 100 percent that two parents with bipolar disorder will pass it on to their children, it does increase the risk of it. In fact, when one parent has bipolar disorder, their child has a 15-30 percent increased chance at developing it.
Studies show that while bipolar disorder is not completely inherent, there are factors of family history that contribute to its early onset. In May of 2013, the staff writers at Healthy Place found that “many children who develop early-onset bipolar disorder include individuals who suffered from substance abuse and/or mood disorders”.
