Severe persistence of primitive reflexes predominantly indicates physical problems such as cerebral palsy, milder persistence is associated with less severe disorders such as learning problems. Asymmetric Tonic Neck Reflex. If asymmetrical tonic neck reflex persists through the babys childhood, it may indicate poor reflex integration, which may also cause the following issues (11).
