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.
Cerebral palsy is not a disease. It is a type of developmental disability caused by damage to the brain before, during, or after birth. It results in the loss of control over voluntary muscles in the body. It occurs in about 2 out of every 1,000 births and many times the exact cause of the brain damage is unknown.
