The nervous system is composed of neurons or nerve cells and their supporting structures. Types of Neurons There are three classes of neurons; each class corresponds to a different aspect of nervous system function. Sensory Neurons. Sensory or afferent neurons are specialized to detect stimuli and transmit information about them to the central nervous system. These neurons may connect any organ to the central nervous system. A stimulus is a change in the environment; it may be light, heat, pressure, or a chemical, for example.
Although there have been no general studies of life expectancy in people with cerebral palsy, most children affected by CP live between 30 and 70 years, depending on the severity of the condition.
Intellectual capability has a strong relationship to the life expectancy of a child with Cerebral Palsy. Even in children who do not have Cerebral Palsy, diminished intellectual function will shorten life expectancy calculation. Intellectual disability occurs in roughly 30%-50% of children with Cerebral Palsy. Cognitive factors that contribute to diminished life span include:
