Developmental disorder refers to a range of conditions that interfere with the normal development and functioning of an individual's physical and mental abilities. These disorders typically manifest during early childhood and can affect areas such as learning, communication, behavior, and social interaction. Examples of developmental disorders include autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), intellectual disabilities, and specific learning disorders such as dyslexia. Treatment for developmental disorders often involves a combination of therapy, education, and medication to help individuals manage their symptoms and improve their quality of life.
