• Cerebral Palsy is a persistent, but not          Something goes awry just before, during or
  unchanging, disorder of movement and              just after birth:
  posture appearing in the early years of life

• Can be acquired

In some instances they are integrated into specific courses, while in other situations students are fully included in the regular classroom for all subjects. The degree of mainstreaming is based in the abilities of the individual; but the trend is for full inclusion in the social and educational life of the community. 5
