| | MedlinePlus Medical Encyclopedia: Cerebral palsy |
 | | Cerebral palsy is caused by injury to the cerebrum (the largest portion of the brain, which is involved with higher mental faculties, sensations, and voluntary muscle activities). |
 | | Initially cerebral palsy was thought to be related to birth asphyxia (strangulation during birth, which leads to lack of oxygen to the brain) and trauma, but in a study of 45,000 births it was shown that birth asphyxia is an uncommon cause of cerebral palsy. |
 | | Cerebral palsy may also occur during early infancy as a result of illnesses (encephalitis, meningitis, herpes simplex infections, and so on), head injury that results in subdural hematoma, blood vessel injuries, and many others. |
