dysthmia
Pronunciation: dis-THY-mee-ah
Chronic form of depression with persistent but less severe symptoms than major depression.
Full Definition
Dysthymia, now termed persistent depressive disorder in DSM-5, is characterized by chronic low-grade depressive symptoms lasting for at least two years in adults (one year in children and adolescents). While symptoms are generally less severe than those seen in major depressive disorder, they significantly impact functioning and quality of life. Patients may experience periods of normal mood, but these typically last less than two months. The chronic nature of dysthymia often leads to substantial functional impairment and increased risk of developing major depressive episodes.
Usage
Usage note: Term largely replaced by 'persistent depressive disorder' in current diagnostic manuals but still commonly used.
