Child Neurology concerns the study of the human nervous system during its development, as it is affected by conductivity, embryology and neuro-immunological factors in developmental brain disorders, coagulation disorders and the metabolism of nervous tissue. During a neurological examination the differential diagnosis depends on the localization of the symptoms within vision, strength, coordination, reflexes and sensation. Neurological disorders of the central nervous system may represent the cause of some mental illnesses, making hard to discriminate between the field of application proper of neurology and the one of psychiatry. As suggested by Jeste et al. child neurologists may provide a substantial contribution to the investigation of neuro-behavioral disorders such as autism, in creation of neurologically based endophenotypes; the detection of early behavioral markers that precede a formal diagnosis and in the comprehension of disorders evolution through the life span.
