Master thesis: Features of early language development after unilateral ischemic stroke
The thesis consists of introduction, three chapters, conclusions, references and appendices.
The first chapter is concerned with the issues of early unilateral ischemic stroke and mechanisms of brain recovery after such an incident. The second chapter describes features of early language development in typically developing children and children with early focal lesion. The third chapter is dedicated to the analysis of features of early language development in children with early unilateral ischemic stroke.
The study is relevant both practically and theoretically. From theoretical point of view, we could gain important insights from studies of such a unique population as children with early focal brain lesions for developmental neuroscience. It could shed light on early brain specialization for language processing, mechanisms of brain reorganization and factors affecting it. From practical point of view, our findings can be used by clinicians working with children after ischemic stroke to predict early language development based on risk factors we discuss.
The object of our study is early language development, the subject is early gesture; receptive and expressive vocabulary and communication aspects, and factors affecting them in children with early unilateral ischemic stroke.
The results of the study are as follows: firstly, when compared with typically developing children, more children from early stroke sample than would be expected by chance had delays in expressive vocabulary and deficits in gesture production. The correlations between early gesture and vocabulary measures generally reflect the pattern observed in normal children, but not in longitudinal perspective. Secondly, when it comes to laterality effects, it turns out that children with left and right hemisphere lesions do not differ on any language aspect we tested. Thirdly, presence of epileptic activity was found to be a predictor for poorer gesture performance and lower family socioeconomic status is associated with lower expressive communication scores. However, younger age at stroke and gender were found to be insignificant factors for early language development in stroke population.
