Causes of Expressive Speech Disorder

The cause of the development of expressive speech is unknown. Minimal cerebral dysfunction or delayed formation of functional neuronal systems are put forward as possible causes. The presence of a family history indicates the genetic determinism of this disorder. The neuropsychological mechanism of the disorder may be associated with the kinetic component, with an interest in the process of premotor parts of the brain or posterior frontal structures; with the lack of formation of the nominative function of speech or the lack of formation of the spatial representation of speech (temporal-parietal sections and the parieto-temporal-occipital intersection) under the condition of normal left hemisphere localization of speech centers and impaired functioning in the left hemisphere.

Symptoms of Expressive Speech Disorder

The disorder significantly impedes success in school and everyday life, requiring verbal expression.

Not associated with general developmental disorders, hearing impairment, or neurological disorder.

Differential diagnosis

It should be carried out with mental retardation, which is characterized by a complete violation of intelligence in the verbal and nonverbal sphere; with general developmental disorders, which are characterized by the absence of an internal language of a symbolic or imaginary game, inadequate use of gestures and inability to maintain warm social relations.

With acquired aphasia or dysphasia, normal speech development is characteristic before trauma or other neurological disorders.
