Persistent depressive disorder (PDD), also known as dysthymia, is characterized by a depressed mood that lasts for at least 2 years, with the presence of at least two additional symptoms such as poor appetite, insomnia, low energy, low self-esteem, poor concentration, or feelings of hopelessness. In contrast, cyclothymia is a milder form of bipolar disorder, involving mood swings between hypomania and mild depression that last for at least 2 years in adults or 1 year in children and adolescents.
