Clinical information

• Bipolar disorder, formerly known as manic depressive illness, is a mental health condition characterized by severe mood swings affecting energy levels, emotions, and behavior.
• Bipolar disorder may also affect one's behavior and energy/activity levels.
• Bipolar disorder is classified into several types based on the severity and nature of mood episodes.
• If the patient exhibits severe depressive and manic symptoms for a minimum duration of two weeks, necessitating hospitalization, they are classified as having Bipolar I disorder.
• In contrast, Bipolar II disorder involves recurrent depressive episodes accompanied by milder manic phases, known as hypomania, which do not require hospitalization.
• A milder variant, cyclothymic disorder, is characterized by frequent mood swings that do not fully meet the diagnostic criteria for either manic or depressive episodes. While the mood shifts in cyclothymic disorder are less intense, they can still disrupt daily functioning and impact the individual's quality of life.
• It is important to differentiate this from severe to mild major depressive disorder and bipolar disorder, current episode manic, or current episode depressed.
• A single manic episode involves heightened energy, euphoria, or irritability, while a major depressive disorder episode includes persistent sadness, hopelessness, and fatigue.
• A mixed episode occurs when a patient experiences symptoms of both mania and depression simultaneously.
• The causes of the disorder, bipolar-type origin, and pinpointing triggers are still significant challenges. However, factors such as genetics, imbalance in brain chemicals, and environment can play a role in affecting one's mental health.
• Contributing factors for this mental illness include genetics, chemical imbalances in the brain, and environmental stressors.
• Individuals with a family history of manic depression or those who have experienced traumatic events are at higher risk.
• Treatments for bipolar disorder include medication, therapy, and ECT. These work hand in hand with living a more active, healthier lifestyle.
