Dysthymia, or Persistent Depressive Disorder (PDD), is a chronic mood disorder characterized by persistent sadness and hopelessness. Unlike major depression, the symptoms of dysthymia are less severe, but they last for an extended period, typically lasting for at least two years in adults and one year in children and adolescents. Individuals with dysthymia may experience changes in appetite, sleep disturbances, low energy, poor self-esteem, and difficulty concentrating. Parents of kids with special needs need to be aware of this condition, as early diagnosis and appropriate support can significantly improve their child’s well-being and overall quality of life.
