What is Bipolar Disorder?
Bipolar disorder, formerly referred to as manic-depressive illness, is a mental illness that causes extreme mood swings. It is characterized by episodes of mania and depression lasting from days to months and usually beginning in late adolescence, but can begin in early childhood or as late as a person’s 40s or 50s. A manic state can be identified by feelings of extreme irritability and/or euphoria. During an episode of mania several other symptoms can occur at the same time, such as agitation, surges of energy, reduced need for sleep, talkativeness, pleasure seeking and increased risk-taking behavior. The other state of depression, produces feelings of extreme sadness, hopelessness and lack of energy. Not everyone’s symptoms are the same. The severity of mania and depression can vary. Bipolar disorder can cause mental suffering, problems with family, friends and co-workers, loss of job productivity, financial problem or death from reckless behavior or suicide.

Causes of Bipolar Disorder
There is no single cause for bipolar disorder. Like all psychological disorders, bipolar disorder is a complex condition with multiple contributing factors including:
- Genetic: Bipolar Disorder tends to run in families, so researchers believe there is a genetic predisposition for the disorder. Scientists are also exploring the presence of abnormalities on specific genes.
- Biological: Researchers believe that some neurotransmitters, including serotonin and dopamine, don’t function properly in individuals with bipolar disorder.
- Environmental: Outside factors, such as stress or a major life event, may trigger a genetic predisposition or potential biological reaction. For instance, if bipolar disorder was entirely genetic, both identical twins would have the disorder. But research reveals that one twin can have bipolar, while the other does not, complicating the environment as a potential contributing cause.
While there is no cure for bipolar disorder, after accurate diagnosis, most people can be successfully treated. Medication is an essential part of treatment and may be prescribed in combination with psychotherapy. Therapy often helps the person learn ways of coping with symptoms and new ways to relate to others. Family members may also benefit from counseling, learning skills to help understand and cope with their loved one’s illness.
