Bipolar Disorders : Definition, Types & Criteria

Bipolar disorder is a complex mental health condition characterized by significant mood swings, including emotional highs (mania or hypomania) and lows (depression). The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), which is the standard classification of mental disorders used by mental health professionals in the U.S., provides specific criteria for diagnosing bipolar disorder.

According to the DSM-5, the diagnosis of bipolar disorder involves the presence of one or more episodes of mania or hypomania. For Bipolar I Disorder, this includes at least one manic episode, which is a period of abnormally elevated, expansive, or irritable mood and increased activity or energy lasting at least one week. The symptoms are severe enough to cause noticeable impairment in social or occupational functioning or to require hospitalization to prevent harm to self or others.

Bipolar II Disorder is characterized by a pattern of depressive episodes and at least one hypomanic episode, without the occurrence of a full manic episode. The hypomanic episode is a period of persistently elevated, expansive, or irritable mood that lasts at least four consecutive days.

The DSM-5 criteria also include descriptions of the specific symptoms that must be present during these mood episodes. During a manic episode, individuals may experience inflated self-esteem or grandiosity, decreased need for sleep, increased talkativeness, racing thoughts, distractibility, an increase in goal-directed activity, and excessive involvement in risky behaviors.

For a hypomanic episode, the criteria are similar but the symptoms are not as severe as those of a manic episode and do not cause significant impairment in social or occupational functioning. Additionally, the mood episodes should not be attributable to the physiological effects of a substance or another medical condition.

The DSM-5 emphasizes that the mood episodes in bipolar disorder represent a significant change from the individual's typical mood and behavior. The diagnosis of bipolar disorder is complex and requires a thorough assessment by a qualified mental health professional. It is important for individuals experiencing symptoms of bipolar disorder to seek professional help for an accurate diagnosis and appropriate treatment.

Understanding the DSM-5 criteria for bipolar disorder is crucial for healthcare providers, patients, and their families. It helps in recognizing the symptoms, obtaining an accurate diagnosis, and initiating the right treatment plan, which may include medication, psychotherapy, and lifestyle changes.
