VISUAL EVOKED POTENTIALS IN THE DIAGNOSIS OF CHILDHOOD MIGRAINES

Abstract

Headache is one of the most common symptoms in neurology and a very common cause of recurrent pain in children. The head, face and soft head are richly supplied with pain receptors compared to other parts of the body, which can explain why pain is so often localized in the head. Headaches are very common in children and adolescents. They have a negative impact on the child's learning, memory, personality, interpersonal relationships or relationships with peers, as well as on the performance of school and extracurricular obligations. This, of course, depends on the etiology, frequency and intensity of the headache. Treatment methods for different types of headache are different. It is important to recognize the type of headache so that it can be treated properly. Each child with a headache needs an individual approach. Timely and proper treatment makes the disease more bearable and gives a better quality of life.

Electrophysiological tests evaluate the function of the visual pathway at a certain level. Visual evoked potentials (VEP) represent the cortical response to a visual stimulus. The VEP parameters that are analyzed and described are the latency, the time interval between stimulation and the appearance of the response, and the amplitude of the P 100 wave. In this study, we examined VEP by testing changes in the amplitude and latencies of the P100 wave during migraines and the calm phase in children.
