[Endogenous and exogenous evoked potentials in the most common neurologic syndromes during development].
This paper presents the application of endo- and egzogenic evoked potentials (EP) in the most frequent neurological syndromes in children and adolescents on the basis of the author's own experiences. The advantages of the method are: objectiveness, noninvasive and the possibility of numerous repetitions. The principles of EPs application and interpretation are established by the recommendations of the International Federation of Clinical Neurophysiology. The analysis of the results contains morphology of recording, latencies and amplitudes of potentials. EPs constitute the important research method in child neurology. They are useful in diagnostics of demyelinating, degenerative and metabolic diseases, tumours of the nervous system, phacomatoses, infections and cerebrovascular disorders, CNS traumas and in cases of psychomotor retardation. The importance of this method consists in 1. diagnosis of symptomatic and asymptomatic pathological processes, 2. localization of the lesion, 3. confirmation of clinical diagnosis, 4. aid in differentiation, 5. monitoring of the treatment, 6. observation of the disease dynamics, 7. evaluation of the prognosis. Endogenic potentials enable neurophysiological evaluation of cognitive processes. Especially P 300 is analyzed in the range of its latency, amplitude and topography. P 300 is evaluated in relation to syndromes and diseases of developmental age, mostly in epilepsy, headaches, tumours, CVS traumas and minimal brain dysfunction.
