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.
While cerebral palsy is not a hereditary condition, researchers have discovered that hereditary factors can predispose an individual to cerebral palsy. Although a specific genetic disorder does not directly cause cerebral palsy, genetic influences can cause small effects on many genes.Genetic influences can also develop gene-to-gene interactions or form complex interactions with multiple environmental influences.lthough familial cerebral palsy only accounts for approximately 1.6% of all cerebral palsy cases, a parent who has a child diagnosed with cerebral palsy has an increased risk of having a second child develop the condition. In these cases, molecular tests can identify the susceptible gene.
