1. Which statement about the development of bipolar disorder is from a biochemical perspective? Show A. Family studies have shown that if one parent is diagnosed with bipolar disorder, the risk that a child will have the disorder is around 28%. B. In bipolar disorder, there may be possible alterations in normal electrolyte transfer across cell membranes, resulting in elevated levels of intracellular calcium and sodium. C. Magnetic resonance imaging studies have revealed enlarged third ventricles, subcortical white matter, and periventricular hyperintensity in individuals diagnosed with bipolar disorder. D. Twin studies have indicated a concordance rate among monozygotic twins of 60% to 80%. What is the biological perspective of bipolar disorder?Chemical imbalance in the brain
Bipolar disorder is widely believed to be the result of chemical imbalances in the brain. The chemicals responsible for controlling the brain's functions are called neurotransmitters, and include noradrenaline, serotonin and dopamine.
What chemically causes bipolar disorder?Experts believe bipolar disorder is partly caused by an underlying problem with specific brain circuits and the functioning of brain chemicals called neurotransmitters. Three brain chemicals -- norepinephrine (noradrenaline), serotonin, and dopamine -- are involved in both brain and bodily functions.
Is bipolar disorder biological or psychological?Bipolar disorder can have several causes
Experts believe bipolar disorder usually develops from a combination of the following factors: genetics. brain chemistry and biology. environmental factors.
How does bipolar disorder develop?Bipolar disorder often runs in families, and research suggests this is mostly explained by heredity—people with certain genes are more likely to develop bipolar disorder than others. Many genes are involved, and no one gene can cause the disorder. But genes are not the only factor.
