Who Is at Risk for Bipolar bang out 2 Disorder?
There are several factors that can contribute to someone having the disorder.
Genetics:Bipolar disorder ishighly genetic.
Having a family history of bipolar disorder also is a strong predictor of developing it.
However, more research and understanding are needed.
Environmental factors:Stress and traumatic events may contribute to triggering bipolar disorder in people with a genetic predisposition.
Symptoms may also appear during pregnancy, after childbirth.
More research is needed to understand the connection between genetics and environmental factors and how they might interact.
Bipolar disorder is highly inheritable, with research suggesting genetics accounts for 60%80% of the risk.
Receiving a correct diagnosis is very important to get the right treatment plan and medications.
When bipolar disorder is misdiagnosed as depression, for example, antidepressants alone may be prescribed.
These may not adequately treat the mood symptoms and may actually worsen the overall course of the illness.
Hypomania includes persistently elevated, expansive, or irritable moods and increased energy.
The depression that is part of this illness can be quite severe and persistent.
