Neurodevelopmental disorders are a group of disorders in which the development of the central nervous system is perturbed. This can include developmental encephalon dysfunction, which can manifest as neuropsychiatric quandaries or impaired motor function, learning, language or non-verbal communication. A child encephalon is not a miniature replica of an adult encephalon, but rather an encephalon in continual development, growing, at times tremendously, subject to illimitable modifications and connections due to the continual stimulation provided by the environment in which it develops.
