Causes of primary speech disorders

primary voice disorders are the result of brain damage during fetal development period.

It is the highest form of development, it is inherent to man, is the basis of mental processes and communication between people.Brain organization of language function has been the subject of interest of clinicians, psychologists and neuroscientists from the middle of the XIX century.The first mention of the mechanisms of functioning of brain speech centers appeared in the works of P. Broca (1861) and Karl Wernicke (1873).

Further studies human cerebral cortex have made it possible to assume that the motor function of speech is localized in the left hemisphere of the brain, in the posterior frontal gyrus (Broca's center).Touch the part of speech is located in the left posterior temporal gyrus (Wernicke's center).

which leads to disruption of speech

Speech pathology is a result of damage to the visual and auditory analyzers, as well as peripheral and central parts of the brain.

If the damage of the peripheral

auditory analyzer suffers from the perception of speech, which is the cause of sensory aphasia (or alalia), while phonemic hearing impaired.

damage various parts of the visual analyzer is accompanied by violation of written speech perception.

Violation of motor zones of the motor analyzer leads to a lack of pronunciation, since suffering the moving parts of articulation (tongue, lips, soft palate) and static (hard palate), as well as bodies of phonation and respiration (vocal cords, larynx, lungs, bronchi, trachea, aperture).All of the above in the literature often referred to as a peripheral speech motor analyzer department.

main causes of speech disorders

speech disorders can occur due to various adverse effects on the brain in utero (during early embryogenesis, 3-4-th month of fetal development), during birth or in the first months and yearslife.

Violations can result in:

  • intoxication mother during pregnancy;
  • toxemia;
  • birth trauma;
  • asphyxia;
  • blood incompatibility between the mother and the fetus Rh (Rhesus-conflict) or blood group;
  • central nervous system (neural infections - meningitis, encephalitis, meningoencephalitis) and brain injury in the early years of a child's life;
  • alcoholism and drug addiction mother;
  • speech deprivation during its intensive development;
  • genetic pathology (speech disturbances have a staunch character and manifested in the general underdevelopment of speech).
