- Аннотация: Background and aims: Modern neuropsychological data suggests that structural and functional abnormalities in brain lateralization are essential part of syndrome of stuttering (Mock et al., 2012; Foundas et al., 2013). We studied relations between lateral organization of motor and sensory functions and pattern of neuropsychological symptoms in adult persons with stuttering. Method: 23 subjects with verified diagnosis of stuttering were participated in the study (15 men, age 23.7±5.7). All subjects participated in complex Lurian neuropsychological testing (Glozman, 2012). The assessment was designed to evaluate the basic cognitive functions: perception, motor functions, speech, memory and neurodynamics component of cognitive activity. The frequency manifestation of the symptoms wa s calculated for each of these functions and total volume was also computed. Pattern of lateral organization was assessed during testing of Hand, Leg, Ear and Eye laterality (modified from Annett, 1970) and correlation between neuropsychological symptoms a nd laterality was calculated. Results: Total volume of neuropsychological symptoms and volume of specific mnestic symptoms correlates significantly with right - ear dominance (R=0.36 and 0.35, respectively). Two hypotheses were suggested: (1) Left vector of brain lateralization in audial perception relates to defects in general functioning and, more specific, in mnestic functions or (2) Right vector relates to compensation of aforementioned defects. Conclusions: Brain lateralization of audial perception («Ear » test) relates to defects of general functioning and, more specific, memory functions in stuttering. No other specific effects for disturbances of perception, motor functions, speech and neurodynamics component of cognitive activity for «Ear» test and n o lateralization effect for any disturbances in « Hand», «Leg» and «Eye» tests were found.
