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.
It is NOT a disease, is not communicable, and is not progressive. It is caused by damage to the brain, rather than muscles. This damage can occur before, during or shortly after birth. Lack of oxygen, illness, poisoning, and head injury are some factors that can cause cerebral palsy. People who have CP may also experience a range of conditions in addition to impaired motor function. These may include: 1  abnormal sensation and perception. 2  impairment of sight, hearing, or speech.
