A Primitive reflex is an automatic motor response to stimulus. Reflexes develop in utero and should be integrated or disappear by 12 months, at the latest. Each reflex serves a purpose and has a function in neurodevelopment. In some children, reflexes are not inhibited or integrated and can then affect subsequent development, learning and behavior. Retained reflexes have been associated with learning difficulties in Dyslexia, Dyspraxia, Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD). Intervention programs are designed to identify retained reflexes and integrated each in succession to improve processing and the neurodevelopmental process.
