What Are Bipolar Disorder's Causes?

For a long time, experts have been perplexed by the etiology of bipolar illness. Many ideas have emerged from research into the sickness, but no one has been able to determine the exact source of this disease that affects over two million Americans, with more being diagnosed each year.

The Brain’s Structure

According to research, one of the reasons of bipolar disorder might be a variation in the brain composition of people who suffer from the condition. Apparently, two crucial regions of the brain in these patients have more cells that convey signals to other sections of the brain. The assumption is that these additional cells might cause an excess stimulation of the organ, which corresponds with what is known about bipolar disorder symptoms.

The Function of Genetics

According to another idea, one of the reasons of bipolar illness might be completely hereditary. Extensive research has been conducted to support this notion, collecting data from the relatives of people with the disease. According to these research, the parents, children, brothers and sisters of a person with bipolar illness are more likely to have a mood disorder of some type than relatives of a person who does not have the condition.

Further research into the genetic conundrum has shown that identical twins with the same genetic composition may also develop bipolar illness. If one identical twin has bipolar illness, the other twin is likely to have bipolar as well. This is compelling evidence that a genetic component is at work.

Although it is unknown what role heredity plays in the causes of bipolar disease, experts believe that uneven levels of neurotransmitters such as dopamine and serotonin in some people may be connected to bipolar disorder. Other investigations have suggested that nerve cell receptors in vulnerable people may be too sensitive, producing the condition, but further study is required to discover precisely what function they play in generating this fatal disorder.


Stressful Situation

A stressful existence, according to scientists, is one of the key elements that might trigger bipolar illness. Many things in life are stressful, but it is up to the person to choose which occurrences produce stress for them. What one individual finds difficult, another may find rewarding. Whatever the source, stress is thought to trigger the onset of bipolar disorder in persons who have never had the condition before. Bipolar disorder seems to thrive after it has begun, nourished by numerous physical and psychological mechanisms.

In conclusion

To summarize what scientific study has revealed and believes to be true, the common opinion is that the causes of bipolar illness should be quite simple for the layperson to comprehend. A subset of the population is born with the genetic proclivity to develop bipolar disorder, and life’s stressful conditions might be enough to lay the scene for the disease. Once started, the sickness remains, worsening over time, and can only be treated, not cured, by medical intervention.

Rest certain that the scientific community will continue to investigate the reasons of bipolar disorder until, ideally, a definitive cause and effect pattern is discovered. Theories will be tested and developed till then, with great expectations for the future.
