چکیده

مقدمه: متغیرهای شناختی همبسته­های مهم اختلال نارساخوانی هستند. پژوهش­های مختلف نشان می­دهند که این متغیرها در کودکان نارساخوان دچار نقص هستند. هم­چنین مطالعات عصب‌شناختی بدکارکردی ارتباط پیشانی ـ گیجگاهی ـ پس­سری را به‌عنوان مبنای عصبی این اختلال مطرح کرده­اند. نوروفیدبک با تغییر ارتباط کارکردی یا هم­نوسانی این مناطق مغزی می­تواند در بهبود کارکردهای شناختی این کودکان مؤثر باشد. پژوهش حاضر با هدف بررسی تأثیر اصلاح هم­نوسانی مغزی از طریق نوروفیدبک بر بهبود آگاهی واج­شناختی و حافظه فعال در کودکان نارساخوان انجام شد. روش: طرح پژوهش از نوع تک آزمودنی پلکانی با خط پایه چندگانه بود که در آن چهار کودک مبتلا به نارساخوانی 20 جلسه 30 دقیقه­ای درمان نوروفیدبک دریافت کردند. یافته­ها: بررسی نتایج پژوهش نشان داد که در نمرات آگاهی واج­شناختی و حافظه فعال آزمودنی­ها بهبودی ایجاد شده است. هم­چنین ­مقادیر هم­نوسانی بعد از اتمام درمان به سمت مقادیر نرمال تغییر پیدا کرد. نتیجه­گیری: این تغییرات نشان می­دهد که نارساخوانی می­تواند به‌عنوان یک اختلال در ارتباط کارکردی مناطق مختلف مغزی مطرح باشد و اصلاح هم­نوسانی از طریق نوروفیدبک می­تواند به اصلاح این آشفتگی کمک کند.

چکیده [English]

Introduction: Cognitive factors are the important correlates of dyslexia. Different researches show that these factors are impaired in children with dyslexia. Also, the studies believe in the dysfunction of fronto-temporo-occipital connection as a neural evidence of dyslexia. Neurofeedback by changing the functional connectivity or coherence of these regions could be useful in improving cognitive functions in dyslexic children. The present study aimed to determine the effectiveness of coherence neurofeedback training on phonological awareness and working memory in children with dyslexia. Method: In this single subject study, four dyslexic children completed twenty 30 minutes sessions of coherence neurofeedback training. Findings: The results showed improvement in the phonological awareness and working memory scores. Also, coherence values changed toward normal values after treatment. Conclusion: These changes indicate that dyslexia could be considered as a dysfunction in functional connectivity between specific brain regions and coherence guided neurofeedback seems to be capable of modifying these disturbances.
