The purpose of the mitochondria in the eukaryote is to provide cellular respiration to the cell. The endosymbiotic theory asserts that the mitochondria came to be part of the eukaryote over time through a symbiotic relationship. The mitochondria consists of two membranes, the inner membrane and the outer membrane.
There is no test that confirms or rules out Cerebral Palsy. In severe cases, the child may be diagnosed soon after birth, but for the majority, diagnosis can be made in the first two years. For those with milder symptoms, a diagnosis may not be rendered until the brain is fully developed at three to five years of age. For example, the average age of diagnosis for a child with spastic diplegia, a very common form of Cerebral Palsy, is 18 months. This can be a difficult time for parents who suspect something might be different about their child.
Brain damage after birth. A small proportion of cerebral palsy cases happen because of damage after birth. This could have happened because of an infection, such as meningitis, a head injury, a drowning accident, or poisoning. When damage does happen, it will do so soon after the birth.
