The neurophysiological mechanisms of convulsions were studied in the stammering syndrome. Electrophysiological, neurological, neuropsychological, and logopedic examinations were performed for 23 children aged 9–10 years with stammering. For comprehensive analysis, a neurophysiological classification was used to divide the stammering children into two groups: group I, which included patients with paroxysmal patterns recorded in the EEG, and group II, which included patients without paroxysmal EEG patterns. The analysis revealed a correlation of specific features of the autonomic regulation with the character of convulsions. Predominant malfunction of the parasympathetic part of the autonomic nervous system and tonic convulsions in stammering were found in the group I children. Malfunction of the sympathetic part of the autonomic nervous system and clonic convulsions in stammering were characteristic of group II children. |
