Amaç: Özgül öğrenme bozukluğu (ÖÖB), çocukluk çağında sık görülen ve çeşitli alanlarda işlev kaybı yaratan nörogelişimsel bir bozukluktur. ÖÖB etiyolojisinin çok faktörlü olduğu bilinmekle birlikte bu konudaki bilgiler kısıtlıdır. Bu çalışmada, ÖÖB tanılı çocuklarda ÖÖB patofizyolojisinde sorumlu olabileceği düşünülen beyin kaynaklı nörotrofik faktör (BKNF) serum düzeyinin belirlenmesi ve sağlıklı kontrol grubuyla karşılaştırılması amaçlanmıştır. Yöntem: 7-12 yaş aralığındaki 30 ÖÖB tanılı çocuk ile 30 sağlıklı kontrol çalışmaya dâhil edildi. Çocuklara, Okul Çağı Çocukları için Duygulanım Bozuklukları ve Şizofreni Görüşme Çizelgesi-Şimdi ve Yaşam Boyu Şekli, Wechsler Çocuklar İçin Zeka Ölçeği-gözden geçirilmiş formu (WISC-R), Öğretmen Bilgi Formu ve Özgül Öğrenme Güçlüğü Bataryası uygulandı. Bulgular: ÖÖB tanılı çocuklarla sağlıklı kontrollerin serum BKNF düzeyleri arasında fark bulunmadı. ÖÖB grubunda BKNF düzeyi ile WISC-R puanları ve okuma hızı arasında korelasyon saptanmadı. Sonuç: ÖÖB ile serum BKNF düzeyi arasında ilişki saptanmamıştır. Çalışmamız, bu ilişkiyi inceleyen ilk çalışma olarak ön veriler sağlamıştır. Homojen fenotip içeren geniş örneklemli ileri çalışmaların yapılmasına gereksinim bulunmaktadır.
Serum Brain-Derived Neurotrophic Factor (BDNF) Level in Children with Specific Learning Disabilities
Objective: Specific learning disorder (SLD) is a neurodevelopmental disorder frequently seen in childhood with deficits in many areas of functioning. Although the etiology of SLD is known to be multifactorial, research findings are limited. In this study, we aimed to compare the serum levels of brain-derived neurotrophic factor (BDNF) in children with SLD to healthy children to find out whether BDNF has a role in the pathophysiology of SLD. Method: The study included 30 children between the ages of 7-12, diagnosed with SLD and 30 age and gender matched healthy controls. The groups were tested on the Affective Disorders and Schizophrenia Interview Schedule for School-age Children–Now and Lifetime Form (K-SADS-PL), the Wechsler Intelligence Scale for Children-revised form (WISC-R), the Teacher Information Form (TIF) and the Specific Learning Difficulty Battery (SLDB). Results: No difference the serum BDNF levels in children with SLD and the healthy controls. BDNF levels did not correlate with the WISC-R scores and reading rate in the SLD group. Conclusion: An association was not determined between SLD and and serum BDNF levels. Our study was the first to investigate this relationship and provided preliminary data on this topic. There is a need for further studies with large patient groups of phenotypic homogeneity.
