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.
Causes of cerebral palsy. Cerebral palsy is caused by a problem in the parts of the brain responsible for controlling movement. It can occur if the brain is damaged in early life or develops abnormally, although the exact cause is not always obvious.n the past, doctors believed that cerebral palsy was caused by brain damage sustained during birth â the direct result of being temporarily deprived of oxygen (asphyxiation). Asphyxiation can sometimes occur during a difficult or complicated birth.
