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.
Although the specific brain injury or problem causing cerebral palsy does not worsen, the movement problems can vary over time. Cerebral palsy is caused by damage to the parts of the brain that control muscles and movement. There are many possible ways that the brain can be damaged, including problems during pregnancy, infection, stroke, genetic problems, lack of oxygen, severe jaundice or diseases that cause the brain to develop abnormally.
