ABSTRACT
Neurologic diseases include all the major patho logic categories that affect other organ systems and can involve one or several areas o f the hum an nervous sys tem. However, adequate management of neurologic prob lems can be based on answering two questions: W here is the problem? W h at is the problem? T he elaboration and analysis o f these specific questions form the major objectives in the study o f medical neuroscience. T he answers to these questions are based on knowledge o f the anatomy o f the nervous system (Rg. 1 .1 ), physiology o f the nervous system, the usual patterns o f disease, and the forms of treatment available. This simplified approach to neurologic disease is the one customarily used by many neurologists, and it includes two questions that address where the problem is (disease), and two questions that address what the problem is (pathology):
1 . Is the responsible disease located at • The supratentorial level? • The posterior fossa level? • The spinal level? • The peripheral level? • More than one level?
