Disruption of verbal communication in children and adolescents with congenital corpus callosum on the background of communication disorders of persons with mild intellectual disabilities and dyslexia – the report based on own research

In the article, language communication disorders in children with agenesis or hypoplasia of the corpus callosum will be discussed. The functional diagnosis of speech therapy should take into account the fact that the reported symptoms and communication disturbance in patients with damage or hypoplasia of the corpus callosum correlate with language disorders on many levels, wherein damage to the right hemisphere of the brain is the basis. The similarity of the symptoms of language disorders in patients with corpus callosum defect can also be seen in dyslexia or oligophasia (in persons with mild intellectual disability). Therefore, the process of therapeutic programming needs to involve preparation of speech differential diagnosis based on the most recent neurological, neuropsychological and neurobiological data. The differential diagnosis and treatment program for patients/ students with hypoplastic of CC (corpus callosum) is included in the revision of the traditional view of the role of each of the cerebral hemispheres in acquisition and development of language. The author takes the view that in the course of language acquisition first of all cooperation between the hemispheres, the foundation of which is working corpus callosum, is of crucial importance.
