When a baby is violently shaken, thrown, or slammed against a hard
surface, his or her head moves forward and backward rapidly. This movement
causes the brain to hit the sides of the skull forcefully, leading to injury
and bleeding in the brain. Brain injury and bleeding cause increased pressure
in the brain, which can lead to permanent brain damage.
Shaken baby syndrome (shaking-impact syndrome) is brain damage caused
when a baby is shaken, thrown, or slammed against an object. Shaken baby
syndrome is a form of child abuse. It occurs in children under the age of 3 and
is most common in babies less than 12 months old.
Young children are more likely to sustain brain damage from an injury
to the head because:
- Their heads are heavy and large in relation to
the rest of their bodies.
- They have weak neck
muscles.
- Their brains are still developing.
You may feel uneasy if your health professional brings up the issue
of child abuse. Health professionals have a professional duty and legal
obligation to evaluate the possibility of child abuse. It is important to
consider this possibility, especially if there were no witnesses to your
child's injury.
If you think your child has been abused, it is your responsibility to
call your health professional or your local child protection agency. Adults
need to protect young children, who cannot protect themselves.
