[Neurodynamic speech disorders in the acute ischemic stroke]

To identify the features of the clinical picture and evaluate the dynamics of regression of neurodynamic speech disorders in comparison with cortical aphasia in patients with ischemic stroke (IS) in the carotid system.

We examined 268 patients with a median age of 59 (54; 70) years in the acute period of IS in the dominant hemisphere with the presence of cortical aphasia or neurodynamic speech disorders. The degree of speech recovery was characterized by an increase in the score on the Speech Questionnaire (ΔSQ) from 1 to 21 days after the development of IS. The patients were divided into group 1 (n=148) with a low level of recovery (ΔSQ≤6) and group 2 (n=120) with a high level (ΔSQ >6).

Of the 268 patients, cortical aphasia was detected in 171 (63.8%) patients, and neurodynamic speech disorders characterized by significant variability of symptoms over the course of hours and days were detected in 97 (36.2%) patients. In patients with cortical aphasia, the majority of patients (63.2%) were classified into group 1, and among patients with neurodynamic speech disorders - into group 2 (58.8%), which showed the stability of the regression dynamics of speech disorders (p=0.001). In patients with cortical lesions the impressive side of speech suffered more often - in this group patients with sensorimotor aphasia predominate. In the case of neurodynamic speech disorders, motor and sensorimotor disorders are observed with approximately the same frequency (p=0.002).

In comparison with cortical aphasias, the sensory component of speech suffers to a lesser extent in neurodynamic speech disorders. Neurodynamic speech disorders generally recover faster and more fully.
