Different plasticity patterns of language function in children with perinatal and childhood stroke.

Ilves P, Tomberg T, Kepler J, Laugesaar R, Kaldoja ML, Kepler K, Kolk A - J. Child Neurol. (2013)

Bottom Line: The verb generation and the sentence comprehension tasks were employed to activate the expressive and receptive language areas, respectively.Weighted laterality indices were calculated and correlated with results assessed by neuropsychological test battery.Perinatal stroke patients showed atypical right-side or bilateral language lateralization during both tasks.

fig1-0883073813489350: Scatterplot of scores with regression line for cognitive expressive language and Weighted Mean Laterality Index (wLI) within Brodmann area (BA) 44 + 45 during the verb generation task (r = –.55, P = .062).

Mentions: In stroke patients negative correlation was found between mean score for the cognitive expressive language tests by the Developmental Neuropsychological Assessment battery and weighted mean laterality index within Brodmann areas 44 + 45 (Spearman’s correlation coefficient r = –.6, P = .036 and Pearson’s correlation coefficient r = –.55, P = .062) (Figure 1). Correlation between scores for the receptive language test by the Developmental Neuropsychological Assessment battery and weighted mean laterality index in Brodmann area 22 during the SC task was not significant (Spearman’s correlation coefficient r = –.42, P = .22, Pearson’s correlation coefficient r = –.37, P = .29). Children with perinatal stroke showed a trend for correlation between score for the receptive language test and weighted mean laterality index in Brodmann areas 22 after the sentence comprehension task (Spearman’s correlation coefficient r = –.8, P = .059, Pearson’s correlation coefficient r = –.79, P = .06), as well as between score for the expressive language test and Weighted Mean Laterality Index in Brodmann areas 44 + 45 (Spearman’s correlation coefficient r = –.5, P = .25; Pearson’s correlation coefficient r = –.47, P = .29).
