F80-F89: Disorders of psychological development
The group of conditions known as Disorders of Psychological Development (F80-F89) encompasses a variety of developmental issues related to speech, language, thought, and motor skills. These disorders usually become evident in early childhood and can affect cognitive, emotional, and physical development. Common symptoms may include difficulties with language comprehension or use, troubles with cognitive processes such as decision-making or problem-solving, and motor challenges. For example, a child may struggle to communicate effectively, have a hard time picking up new skills, or display abnormal physical behaviors. The cause of these disorders often varies but may include genetic factors, environmental influences, or complications during pregnancy or childbirth. The progression of these conditions can differ greatly from person to person, as can the impact on an individual's day-to-day life. The conditions in this group primarily affect the brain and nervous system, but can also impact other body systems.
