Illustration of cerebral palsy. The illustration on the left shows the causes of congenital cerebral palsy, a pathology resulting from damage to the motorneurons in the central nervous system of the foetus, shown here with the motor cortex in green. The illustration on the right shows a movement being carried out from the brain to the arm muscles, due to motorneurons. It illustrates the damage of this pathology. Motor impairment in cerebral palsy is often accompanied by sensorial, perceptive, cognitive, communication and behaviour impairment as well as secondary musculoskeletal problems.
