What are the chances of recovery from shaken baby syndrome?

As compared to accidental traumatic brain injury in infants, shaken baby injuries have fewer chances of recovery. Damage to the retina of the eye can cause blindness. The majority of infants who survive severe shaking will have some form of neurological or mental disability, such as cerebral palsy or mental retardation, which may not be fully apparent before six years of age. Children with SBS may require lifelong medical care.
