Bipolar disorder, previously known as manic depression, is a mood disorder that involves significant fluctuations in mood and behavior, commonly referred to as “cycling.” Individuals with bipolar disorder often experience alternating periods of extreme highs and lows. The intensity and duration of these fluctuations are used by medical professionals to differentiate between bipolar I and bipolar II.
Statistics
Bipolar disorder affects approximately 2.8% of adults in the United States on an annual basis. Out of this percentage, around 83% are categorized as having severe symptoms. It is interesting to note that both men and women are equally affected by this disorder. Moreover, about two-thirds of individuals with bipolar disorder have a family member, such as a parent or sibling, who also experiences this condition.
Causes of Bipolar Disorder
Bipolar disorder is influenced by various factors, with genetics playing a significant role in its development. Individuals who have a family history of the disorder, particularly those with a parent or sibling affected, are at a higher risk of developing bipolar disorder themselves. Additionally, research indicates that there are distinct biological differences in the brains of individuals with bipolar disorder, suggesting the involvement of other important biological factors as well.
