Bipolar means you have mixed emotions. For example, you can be super happy at one moment and then later you can feel depressed. Being bipolar isn't bad but, its better not to be.An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, reports that abnormal sequences of DNA known as rare copy number variants, or CNVs, appear to play a significant role in the risk for early onset Bipolar disorder.
The findings will be published in the December 22 issue of the journal Neuron.
CNVs are genomic alterations in which there are too few or too many copies of sections of DNA. Researchers have known that spontaneously occurring (de novo) CNVs - genetic mutations not inherited from parents - significantly increase the risk for some neuropsychiatric conditions, such as schizophrenia or the autism spectrum disorders. But their role was unclear in bipolar disorder, previously known as manic depression.
Principal investigator Jonathan Sebat, PhD, assistant professor of psychiatry and cellular and molecular medicine at UC San Diego's Institute of Genomic Medicine, and colleagues, found thatde novo CNVs contribute significant genetic risk in about 5 percent of early onset bipolar disorder, which appears in childhood or early adulthood.
In other words, said the study's first author Dheeraj Malhotra, assistant project scientist in Sebat's lab, "having a de novo mutation increases the chances of having an earlier onset of disease."
The cause or causes of bipolar disorder remain unclear. There is a clear genetic component - the disease runs in families - but previous studies that have focused mainly on common inherited variants have met with limited success in identifying key susceptibility genes.
Bipolar disorder affects men and women equally and usually appears between the ages of 15 and 25. The exact cause is unknown, but it occurs more often in relatives of people with bipolar disorder.
One can find information on what causes bipolar disorder in humans by using websites such as Wikipedia or NIHM that tells you everything you need to know about bipolar disorder and how it is caused in humans.

Bipolar disorder is a mood disorder which causes unusual and dramatic shifts in a persons behavior. A bipolar attack is a period of time in which the symptoms are most unmanageable.
There are many causes for depression and bipolar disorder. One can develop these symptoms due to stress, life changes, diet and lifestyle habits, and injury or illness.
It's a gene mutation. And it is different for each organ.
Doctors think that bipolar disorder is caused by stress. Others believe that it's a mental illness that you can treat with medicine.
Bipolar Disorder is characterized by heavy mood swings that occur randomly. The exact cause of bipolar disorder is unknown but there seem to be some factors that help trigger bipolar episodes. Some of these causes include differences in neurotransmitters, biological parts, hormones or inherited traits. Also, stress and traumatic events may play a large role in developing bipolar disorder.
We do not know at this time. Nothing is known for certain about any of its possible causes.
unknown, its probably not a single gene but instead many
There are so many . . . I can think of bipolar disorder, depression, disassociation disorder, panic disorder, personality disorder, asocial disorder among the many.
