Even though cerebral palsy affects muscle movement, it isnât caused by problems in the muscles or nerves. Mitochondrial disorders occur when the mitochondria fail and are not able to produce the energy a cell or tissue needs. Cerebral palsy affects the motor area of the brainâs outer layer (called the cerebral cortex), the part of the brain that directs muscle movement. Mitochondrial disorders appear to cause most damage to the brain, heart, liver, skeletal muscles and kidney, which are the tissues with the highest demands for energy.
Damage to any of these parts of the brain may cause cerebral palsy. 1  Spastic â Spastic cerebral palsy is caused by damage to the motor cortex. 2  This causes exaggerated, jerky movements.3  Athetoid/dyskinetic â Athetoid CP is caused by damage to the cerebellum and/or the basal ganglia.amage to different parts of the brainâs motor control centers causes different types of cerebral palsy. The level of disability depends on the severity and timing of the brain injury. 1  About 70 percent of cerebral palsy cases are caused by prenatal injuries. 2  About 20 percent are caused by injuries during birth.
