A neurodevelopmental disorder refers to conditions that typically manifest early in development and involve impairments in brain function that affect cognitive, motor, or social skills. Examples include autism spectrum disorder, ADHD, and intellectual disabilities. These disorders are often linked to structural or functional abnormalities in the brain that can be observed over time. On the other hand, functional disorders primarily involve symptoms related to emotional or psychological functioning, but without clear brain abnormalities. These disorders, such as anxiety or depression, often arise from psychological stressors or imbalances in mood regulation.
