Primitive reflexes are seen in babies. As the brain develops these reflexes are over-ridden, first by Postural Reflexes (which Darren will also test) then by more sophisticated movement patterns at which point the primitive reflex is no longer seen.
If the primitive reflex is still present in an older child it is an indication that the brain’s control of movement and posture has not developed appropriately. There is some evidence that children who have been diagnosed with learning disorders have more primitive reflexes than neurotypical children. When certain primitive reflexes are retained they have been associated with particular coordination, sensory or behavioural issues.
The presence of some primitive reflexes at 2 years old is a predictor of lower scores in development at 8 years old.
