Objectives

KNOWLEDGE AND UNDERSTANDING: the student will have to show knowledge of neurological semeiotics, to be able to differentiate normal from abnormal objective signs of the central nervous system. The student will also have to acquire the theoretical notions relating to the anatomy and physiology of the nerve pathways that can be investigated using evoked potentials and orient themselves in the pathological pictures that require the application of this method of investigation. Finally, he will have to show knowledge about the methods of recording evoked potentials, their application in the diagnostic field, the characteristics of the equipment, and the various modalities of patient stimulation.
APPLICATION SKILLS: the student must be able to apply the theoretical knowledge acquired to recognize and distinguish the different pathologies of the Central Nervous System, as well as be able to identify the diagnostic framework and the therapeutic choice to be adopted by orienting himself in the differential diagnosis with other pathologies. The student must also be able to apply the theoretical knowledge acquired to recognize and distinguish the modes of functioning of the nervous pathways and the signs of any pathological alterations in the registration of evoked potentials. the student must be able to apply the theoretical knowledge acquired to recognize and distinguish the modes of functioning of the neurological pathways and the signs of any pathological alterations in the registration of evoked potentials.
The student will therefore be able to apply the theoretical knowledge acquired to recognize and distinguish the different types of evoked potentials with a particular focus on the interpretation of the traces.
AUTONOMY OF JUDGMENT: the student will be able to interpret the anamnestic and instrumental data to formulate a diagnostic judgment concerning the pathologies of the Central Nervous System as well as orient himself in the differential diagnosis with other pathologies. The student will be able to correctly interpret and analyze how the application of evoked potentials allows investigation of the functioning of a specific nerve pathway.
COMMUNICATION SKILLS: the student will be able to carry out the pathophysiological process and the outcome of diagnostic procedures and therapeutic interventions in the field of Central Nervous System diseases. the student will be able to correctly interpret and analyze how the application of evoked potentials allows to investigate the functioning of a given nervous pathway and to explain the theoretical notions necessary for the clinical interpretation of the evoked potentials and any alterations of the pathway investigated and explain the outcome of diagnostic procedures and the relative methods of recording the evoked responses.
LEARNING SKILLS: the student will learn to acquire new information and implement their cultural background critically through the consultation and critical interpretation of recent scientific literature in the field of evoked potentials and will be able to analyze the signals recorded through the interpretation of traces presented and discussed during the course of the lectures.

Teaching Methods

Pathophysiology of the central nervous system (PE)
Lectures with examples, guided experiences with real instrumentation aimed at the acquisition of the concepts explained with practical examples. Practical exercises of interpretation and analysis of clinical cases. Practical exercises of interpretation of instrumental investigations used for the study of central nervous system pathologies.
Neurophysiopathology 4 (Basic and clinical PE)
Lectures with examples, guided experiences with real instrumentation aimed at the acquisition of the concepts explained with practical examples. Practical exercises of interpretation and analysis of clinical cases. Practical exercises on the interpretation of the lesion levels of the nervous pathway according to the pathological picture and the alterations in the evoked potentials.
Electroneurophysiological techniques 6 (PE)
Lectures with examples, guided experiences with real instrumentation aimed at the acquisition of the concepts explained with practical examples. Practical exercises of interpretation and analysis of the traces with observation and discussion centered on the identification and analysis of patterns recorded through the use of evoked potentials.

Verification of learning

Oral and practical exam.
Oral interview based on the topics covered in class during which the student will have to demonstrate that he has learned the basic concepts relating to the application and execution of the most common techniques of evoked potentials. The assessment for the verification of learning requires that 2 questions are administered, one of which is more theoretical on the methodology of evoked potentials and one more focused on clinical applications. The final grade will result from the average of the marks obtained for the two questions administered.
