Types of brain injury

Brain injury that occurs before birth (congenital).
Congenital brain injury is a group of brain defects or disorders that develop in the womb and are present at birth.

Brain injury that occurs after a child is born (acquired).
Acquired brain injuries can be traumatic or non-traumatic. A traumatic brain injury occurs when there is impact to the head or body causing the brain inside the skull to be injured. Including the brain moving back and forth inside the skull and being bumped, bruised or twisted. The injury can be mild, moderate or severe.

Brain injury in children and adolescents

Every brain and every brain injury is unique. Each individual’s recovery from a brain injury requires individual attention.

Many factors can influence outcomes (how quickly and how well a person recovers). The care of a child or adolescent with a mild, moderate, or severe brain injury can be complex and requires a comprehensive team of pediatric brain injury specialists.  The team of specialists can include neurosurgery, trauma surgery, physical medicine & rehabilitation, neurology and interdisciplinary professional staff specially trained to care for children and adolescents.

Immediately after a brain injury, symptoms can show up right away and get better over time or symptoms may be delayed and get worse over time. We specialize in brain injury at Hennepin Healthcare. Learn more about our program.
