Influence of Genetics on Bipolar Disorder

    This article discusses a study on individuals with bipolar disorder and individuals without bipolar disorder from various racial groups to determine the role genetics has on this disorder. To preface, bipolar disorder is a when a person experiences extreme mood shifts and episodes of depression. The results showed that about 300 gene locations and 6 different genes are linked to bipolar disorder. This study also lead researchers to notice the differences in the organization of genes of the people who have the disorder. The genes that are linked to bipolar disorder are associated with an increased risk of schizophrenia and depression. A lot is still unknown about this specific disorder but this research could potentially lead to more helpful or long term treatment opportunities.

   As mentioned above, genes that are linked to bipolar disorder can also be related to the risk of other mental disorders. It is very interesting to me that people can only have one of the disorders and not experience all of them if the genes overlap. I find this research to be extremely beneficial to help people battling with mental illnesses. The cause of bipolar disorder is partially due to specific genes and their different architectures but also environmental factors do influence a person being diagnosed with bipolar disorder. There is not one specific gene or even cause that makes someone have bipolar disorder making the treatment difficult. Also, bipolar disorder varies within people. Hopefully with time and research, studies are able to understand why people have different experiences with the disorder. I hope that this research is able to help people find the correct solution to this disorder for them. This study will help the production and creation of more personalized treatments to help individuals living with bipolar disorder.
