In the second volume, disorders of higher cognitive processes in childhood are discussed in detail. In the section on child neuropsychology, the authors place emphasis on language and speech disorders. Language and speech development are considered fundamental in the overall cognitive development of the child, which is also a central idea in the work of the classics L. Vygotsky and J. Piaget, and one of the main scientific directions in the professional path of the authors. The topic of speech and language disorders in focal cerebral palsy pathology both in development and in adults, on models of impaired language functioning, is one of the main ones in the entire three-volume. A main place for the problems of aphasiology is allocated in the third volume, which is devoted to neuropsychology in adults. The author - Prof. Raichev - is a doyen of neuropsychology in Bulgaria, one of the founders of the clinical, research and teaching practice at the university level in this interdisciplinary field.
The second volume focuses on the clinical form of disorders of higher mental functions in children. The requirement that these disorders are not primarily related to mental retardation or established deficits of the perceptual systems (auditory and visual) is irrevocable and precisely formulated, i.e. not have primary deafness or blindness. The subject of children's neuropsychology is completely analogous to that of adults - pathology of cognitive processes and, above all, of higher mental functions. Topics covered include neurophysiology of child cognitive development; historical overview of the problems of developmental disorders and learning difficulties in childhood; impaired language development - disorders of spoken speech, developmental dysphasia, dyslalia, childhood aphasia, dysarthric disorders in children's speech and others. Written speech and developmental disorders are also discussed - general ideas about the written forms of language realization, disorders in the development of written speech, developmental dyslexia and dysgraphia, reading disorders in childhood. Arithmetic functions and their disorders in childhood, attention as a cognitive function, comorbidity or systematicity in neuropsychology and others are also described.
