Primitive reflexes are automatic movement patterns present from birth that are meant to hand over to voluntary control within roughly the first year of life. In a meaningful proportion of children, that handover doesn’t fully complete — the reflex is retained, not lost or regressed. Research links retained reflexes at preschool and school age to motor difficulties, attention deficits, and learning difficulties including reading, writing, and dyslexia, and shows that structured programs can reduce retained reflexes while improving motor, cognitive, and academic performance.
