Clinical Significance
Cyclothymic disorder is a chronic mood disturbance involving numerous periods of hypomanic symptoms and depressive symptoms that do not meet criteria for a full hypomanic or major depressive episode. This condition is part of the bipolar spectrum but distinct from bipolar I and II. It represents a chronic low-grade mood instability that can significantly impact quality of life and may evolve into bipolar I or II over time.
