Which two features characterize developmental disorders?

• A. They emerge during development and there is no associated neurological injury
• B. They emerge after injury
• C. They are always present at birth with injury
• D. They are primarily motor disorders

Answer: (A)

Developmental disorders are conditions that start during the developing years, typically early in life, and are not caused by an identifiable neurological injury occurring later. The two defining features are: onset during development and absence of a clearly associated brain injury. This distinguishes them from conditions that arise after an injury or later-life event. Also, developmental disorders are not limited to motor problems; they often involve language, social interaction, attention, or learning, though motor issues can be present in some cases. So the combination of starting in development and lacking an injury best captures what these disorders are.
