USING CERVICAL VESTIBULAR MYOGENIC EVOKED POTENTIALS FOR PREDICTING COGNITIVE AND MOTOR DEVELOPMENT OF A CHILD

The article explores both theoretical and practical aspects of using cervical vestibu-lar evoked myogenic potentials (cVEMP) in psychology and psychophysiology. It highlights the role of the vestibular system not only in maintaining balance but also as an important con-tributor to cognitive and motor development in children. The cVEMP method is a neurophysi-ological technique that assesses the function of the saccule and the inferior part of the vestibu-lar pathway. Experimental data are presented on the application of cVEMP for diagnosing children with various developmental disorders and learning difficulties, such as long-term ef-fects of prematurity and complicated birth, severe speech development disorders, autism spec-trum disorders (ASD), and attention deficit hyperactivity disorder (ADHD). The article pro-vides evidence of the association between vestibular dysfunction and impairments in spatial memory, body schema formation, and other cognitive functions. It is shown that vestibular dysfunctions are not limited to children but also accompany brain aging and are characteris-tic of conditions such as Alzheimer's and Parkinson's diseases. The paper discusses the role of vestibular dysfunction as a potential biomarker of neurological disorders, the importance of spontaneous motor activity in the lives of children and adults, and the possibilities for correct-ing vestibular dysfunctions through psychoeducational interventions. Special emphasis is placed not only on movement but also on the use of rhythm and low-frequency music, as the saccule evolutionarily retains the ability to register loud low-frequency sounds. This so-called vestibular hearing supports cochlear hearing and plays a role in speech perception. These findings support the inclusion of cVEMP in diagnostic protocols for children and adults with various cognitive impairments. cVEMP can help identify vestibular system dysfunctions and monitor changes resulting from corrective and developmental interventions.
