Understanding Bipolar Disorder

Learn About Bipolar Disorder

Bipolar disorder, once known as manic depression, is a serious mental illness which includes exaggerated mood states. Bipolar disorder involves shifts in moods between mania and depression. Bipolar disorder includes both the highs and lows of moods resulting in risky behaviors, loss of relationships and thoughts of suicide. At times there may be neutral states between these extremes though some individuals switch back and forth between the extremes without experiencing a return to neutral.

Part of the difficulty in diagnosing bipolar disorder is there is no defining pattern for mood states and each individual can display a different pattern or change patterns over time. The mania phase involves a highly energetic, euphoric state during which individuals have a decreased need for sleep, talk excessively and make grandiose plans which are often delusional. The depressed phase is characterized by the opposite symptoms including excessive sadness, lack of energy, decreased speech production and lack of motivation. While most adults don’t cycle very frequently, the periods between the cycles are often characterized by extreme anxiety caused by anticipation of the next extreme mood state.

There are three primary types of Bipolar disorder.

  1. Bipolar I which is manic symptoms and at least one major depressive episode.
  2. Bipolar II has hypomanic symptoms which are predominantly the same as manic symptoms though at a lower intensity and severity level and at least one major depressive episode.
  3. Cyclothymic Disorder involves hypomanic-like symptoms which don’t meet criteria for a hypomanic episode or a major depressive episode.

Bipolar Disorder has historically been difficult to diagnose in children and adolescents as the diagnostic criteria are not developmentally sensitive. The symptoms based upon how the disorder manifests in adults have been applied to children in order to obtain a diagnosis. However, it has been recognized the presentation of bipolar disorder in childhood is quite different from what is seen in adulthood.  Diagnosing children is made even more difficult because the presentation of bipolar disorder is very different between children and adolescents as well.


Statistics for Bipolar Disorder

The 12-month prevalence rate for bipolar I in adults in the U.S. is estimated at 0.6%. The lifetime male to female prevalence ratio was estimated at 1.1 to 1 indicating the gender difference in prevalence of bipolar I is not large. The 12-month prevalence rate for bipolar II in U.S. adults is estimated at 0.8%.

The lifetime prevalence estimates for cyclothymic disorder range from 0.4% to 1%. In the general population, rates of cyclothymic disorder appear to be equal among males and females though estimates for clinical settings indicate a higher rate in women than men indicating women are more likely to seek treatment.

Causes & Risks

Causes & Risk Factors of Bipolar Disorder

The specific causes of bipolar disorder are unknown however there is support indicating certain factors are linked to the development of this group of disorders.

Genetic: Bipolar disorder has been recognized to run in families.

Brain Chemistry: Chemicals called neurotransmitters are responsible for communication in the brain. Some of these neurotransmitters, norepinephrine, dopamine and serotonin, have been implicated in the development of bipolar disorder. Abnormal levels of these neurotransmitters have been strongly linked to disruptions in both manic and depressed mood states.

Environmental: Children of parents with bipolar disorder often live in a chaotic environments. They must cope with the confusion associated with the parent’s mood swings, the effects of substance abuse, financial hardship, witnessing sexually promiscuous behavior and the absence of the parent. As these children are genetically predisposed to developing bipolar disorder, these stressors can lead to the development of bipolar disorder or other mental illnesses.

My husband had a manic episode and needed serious help. I was scared for our family and wasn't sure what to do. Acadiana stabilized his mental condition and taught him ways to manage his newly diagnosed Bipolar II disorder. Now he is back to his old self and our family has never been better.
