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.
Every case of cerebral palsy is unique to the individual. This is due in part by the type of injury, extent of injury, and the timing of injury to the developing brain. The brain damage that causes cerebral palsy is a result of either: 1  Prenatal disturbance of brain cell migration â genetic and environmental factors disturb brain cell migration as cells move to their appropriate location during brain development.
