Bipolar Disorder Signs and Symptoms

Characterised by periods of mania and depression, bipolar affective disorder can cause enormous disruption in a person’s life. During manic episodes, a person can feel excesses of energy, behave impulsively, and spend a great deal of time pursuing unrealistic goals. Depressive episodes involve feelings of sadness, low energy, and a loss of ability to feel pleasure. Some people also experience mixed episodes with some symptoms of a manic episode and some symptoms of a depressive episode occurring at the same time. Certain people also have episodes of a less severe form of mania known as hypomania. During hypomanic episodes, people experience symptoms of mania that are not severe enough to qualify as full manic episodes.

Bipolar affective disorder can range in severity, and people who struggle with the most severe form may experience hallucinations or other forms of psychosis. While some people struggle with severe forms of bipolar affective disorder, others can struggle with a range of bipolar-like symptoms, including the following:

  • Cyclothymia: People with cyclothymia experience symptoms of manic episodes and symptoms of depressive episodes, but these symptoms are not severe enough to warrant a full bipolar affective disorder diagnosis.
  • Recurrent manic episodes NOS: Sometimes, people experience repeated manic episodes without depressive episodes. In this situation, a person would be diagnosed with recurrent manic episodes NOS.

When a person is struggling with a substance use disorder in addition to co-occurring bipolar affective disorder, the two disorders can build upon each other and cause immense devastation in a person’s life if he or she does not seek help. If you feel you or a loved one is struggling with bipolar disorder, proper treatment can help you manage the symptoms.

Statistics

Across the U.K., approximately 1% to 2% of people will struggle with bipolar affective disorder during their lives. A 2002 study by the National Health Service (NHS) found the annual total cost of bipolar disorder to be approximately £2 billion, which accounts for both direct healthcare costs as well as indirect costs such as lost productivity.

Causes and Risk Factors for Bipolar Affective Disorder

Although the exact causes of bipolar affective disorder are still being researched, experts generally agree that the following factors play a role:

Genetic: Evidence suggests that bipolar affective disorder tends to run in families. Approximately 10% to 15% of people with the disorder have family members who also have the disorder.

Environmental: In addition to genetic factors, environmental factors can also affect a person’s chances of developing bipolar affective disorder. For example, people who have been separated, divorced, or widowed are more likely to develop the disorder than are people who are married or who have never been married.

Risk Factors:

  • Family history of bipolar affective disorder
  • Being separated, divorced, or widowed
  • Living in a high-income country
