What are bipolar disorders?
Answer
Bipolar disorders are a group of chronic psychiatric conditions characterized by severe episodic fluctuations in mood, energy, activity levels, and concentration. Unlike typical mood changes, these shifts range from emotional highs (mania or hypomania) to deep lows (major depression), impacting daily functioning, relationships, and cognitive processing.
Bipolar I disorder requires at least one manic episode lasting at least 7 consecutive days or requiring immediate hospitalization and/or presenting with psychotic features. Mainic episodes are marked by high energy, racing thoughts, rapid speech, reduced need for sleep, and impulsive or risky actions. There is a high risk of psychosis (delusions or hallucinations) during peak mania, often necessitating acute inpatient stabilization. Depressive episodes are characterized by deep sadness, low energy, fatigue, feelings of worthlessness, and difficulty concentrating.
Bipolar II disorder is characterized by at least one hypomanic episode and one major depressive episode. While hypomania is less severe than full mania, the depressive episodes are often recurrent, prolonged, and severe.
Cyclothymic disorder features a chronic, fluctuating mood disturbance lasting for at least 2 years in adults--1 year in children and adolescents. Involves numerous periods of hypomanic symptoms and depressive symptoms that do not meet the full diagnostic criteria for hypomania or major depression.
Although there are no cures for bipolar/mania, it is really important that these patients are treated. Lithium is the prototype of mood stabilizer. It is better at treating manic rather than depressive episodes. Mood-stabilizers antiepileptic medications such as carbamazepine, valproate, and lamotrigine are other prototypes.
