Neurological examination

The nervous system examination is to determine whether the nervous system is damaged and the location and extent of the damage, that is, to resolve the "localization" diagnosis of the lesion. The examination should be in a certain order, and pay attention to the combination with the general medical examination. Usually check the cranial nerve, including its motor, sensory, reflex, and autonomic nerve functions; then check the upper and lower limb motor systems and reflexes, and finally check the sensory and autonomic nervous systems. Examination should also be based on medical history and preliminary observations. It is more important to focus on the examination of critically injured patients. In addition, dysfunctions of the cerebral cortex, such as consciousness, aphasia, apraxia, and failure to recognize, also belong to the category of neurological examination.
