Signs & Symptoms of Bipolar Disorder

Characterized by episodic cycles of mania and depression, bipolar disorder is severe mental health condition that can cause a great deal of impairment in a person’s functioning at home, school, work, and/or in the community. Classified into three types, bipolar disorder can manifest in varying ways and different degrees of severity. These three types are:

Bipolar I: This form of bipolar disorder features periods of mania and depression, of which can be intense and extreme in nature. Considered to be the most severe type, bipolar I can present differently in people as some experience more episodes of depression than mania, more episodes of mania than depression, or both mania and depression at the same time.

Bipolar II: Compared to bipolar I, bipolar II is a less severe form of bipolar disorder. Involving episodes of chronic depression, bipolar II’s episodes of emotional highs are hypomanic and do not cause the same level of disruption as mania.

Cyclothymic disorder: The mildest form of bipolar disorder is known as cyclothymic disorder. Still including episodes of depression and hypomania, this type’s symptoms occur less often and do not cause the degree of devastation that bipolar I and bipolar II can.

Treatment can vastly improve the lives of those who are grappling with the debilitating symptoms of bipolar disorder. Medications that can correct imbalanced chemicals within the brain and improve a person’s ability to regulate emotions, in addition to therapeutic interventions that help individuals learn how to manage symptoms and develop coping skills, have proven effectiveness in treating this illness. Lastly, treating bipolar disorder can reduce the harmful effects that are likely to occur when the symptoms of this disorder are left to consume a person’s life.

Statistics

Research has concluded that nearly 3% of adults in the United States suffer from bipolar disorder, which accounts for almost 6 million Americans. Average age of onset for this mental disorder is 25, however signs and symptoms of bipolar disorder can occur at any age. Lastly, it is believed that those with a parent who suffer from bipolar disorder have a 15-25% greater likelihood of experiencing onset set of symptoms at some point in life.

Causes and Risk Factors for Bipolar Disorder

The onset of bipolar disorder is believed to be caused by a number of influences. A person’s genetic history, physiological make up, environment, and other risk factors are known to contribute to the development of this mental health condition. The following explanations elaborate on these influences:

Genetic: As with other mental health conditions, bipolar disorder is said to be a heritable illness as it can be found in individuals who share the same genes. Especially in those with a biological mother or father who have bipolar disorder, the vulnerability to developing this condition is higher when a family history of this disorder is present.

Physical: Bipolar disorder symptoms are believed to manifest when there are chemical imbalances in the brain. These chemicals, also known as neurotransmitters, are responsible for transmitting information within the brain and are liable for regulating emotions. Disproportionate levels of these chemicals can ultimately trigger the onset of bipolar disorder. Lastly, unstable hormones are also linked to the start of bipolar disorder in some people.

Environmental: When an individual has a genetic predisposition to bipolar disorder, certain environmental influences can trigger or exacerbate existing symptoms of bipolar disorder. A widely accepted belief among mental health professionals is that the use or abuse of drugs and/or alcohol can serve as an environmental trigger that can bring about symptoms of bipolar disorder earlier in a person’s life.

Risk Factors:  

  • Family history of bipolar disorder or other mental illness
  • Experiencing chronic stress or abrupt life changes
  • Exposure to trauma
  • Substance use or abuse
