Title : The informativeness of long-latent auditory evoked potentials in violation of psychological development in children
Abstract:
In recent years, there has been an increase in the number of patients with speech development disorders, respectively, and with cognitive deficits. The identification of the etiology and pathogenetic mechanisms of speech disorders is an important task and is necessary to determine the further tactics of treatment of the patient. The variety of clinical manifestations in this disorder is due to the anatomical and functional characteristics of the central parts of the auditory analyzer. The clinical picture of CSD in children corresponds to the term "impressive speech disorder" widely used in European countries. In recent decades, the number of studies devoted to the study of the neuroanatomical and functional foundations of speech has increased significantly, which has been greatly facilitated by the emergence of new neuroimaging methods, such as functional magnetic resonance imaging. However, despite all its advantages, these techniques can be used only in children suffering from mental and speech development disorders. At the same time, such neurophysiological techniques as electroencephalography and evoked brain potentials remain relevant, which allow us to assess the functional activity of the cerebral cortex, including the temporal characteristics of this activity in response to the presentation of a stimulus. Currently, Cortical Auditory Evoked Potentials (CAEP) is one of the most widely used methods in cognitive neuroscience research to study the physiological correlates of sensory, perceptual, and cognitive activity related to information processing. The object of the study was children aged 4 to 6 years. The aim of the study is to identify the dependence of cortical sensory processing disorders by studying long-latent auditory and cognitive evoked potentials depending on the severity of clinical manifestations, namely speech and behavioral disorders.
Audience Take Away Notes:
- The analysis of the data obtained during the study revealed early predictors of differential diagnosis of autism spectrum disorder and motor alalia in children under the age of 3-4 years.
- This study is an attempt to create a common practical field, namely: for neurologists, psychiatrists, specialists in speech therapy, speech therapists, teachers for the diagnosis and support of children with autism spectrum disorder.
