Amaç: Dikkat eksikliği hiperaktivite bozukluğu (DEHB) olan çocuklarda metilfenidat tedavisi öncesi ve sonrası beyin kan akımlarının karşılaştırılması. Yöntem: Sağ elini kullanan, önceden ilaç kullanmamış, zeka bölümü 80’in üstünde olan, DSM-IV ölçütlerine dayanan görüşmelerle ve ölçeklerle DEHB tanısı konmuş 11 erkek olgu çalışmada yer almıştır. 4-18 Yaş Değerlendirme Ölçeği ve Öğretmen B‹lgi Formu belirtilerin yaygınlığının anlaşılması, çocuk depresyon ölçeği olası depresyon eş hastalanımının değerlendirilmesi, WISC-R Zeka Testi de zeka düzeyinin belirlenmesi için kullanılmıştır. Her bir çocuk için ilaçtan önce ve 3 aylık metilfanidat kullanımından sonra, verilen okuma parçasını okurken iki SPECT görüntüsü alınmıştır. Bu görüntüler kendi aralarında karşılaştırılmıştır. Sonuçlar: 3 aylık metilfenidat tedavisinden sonra, tedaviden öncekine göre sağ ön parietal bölgede kan akımında istatistiksel olarak anlamlı derecede azalma, sol temporal bölgede ise kan akımında artış saptanmıştır. Tartışma: Metilfenidat kullanımından sonra metod kısıtlılıklarına rağmen, özellikle sağ ön parietal bölgede görülen kan akımı değişimi ilacın dikkat arttırıcı etkisinin açıklanmasında yardımcı olabilir.
SPECT in Children with Attention Deficit Hyperactivity Disorder Before and After Methylphenidate Treatment
Objective: Comparing cerebral blood sow of children with attention deficit hyperactivity disorder (ADHD) before and after methylphenidate treatment. Method: Subjects were 11 male, right handed, with IQ scores greater than 70, never medicated children with ADHD, diagnosed with interviews using DSM-IV criteria and scales. We used Child Behavior Checklist (CBCL 4-18), Teacher Report Form (TRF) for assessment of pervasiveness of symptoms, Children Depression Inventory (CDI) for assessment of depression scores, and WISC-R for assessment of IQ scores. Two images were taken with SPECT for each child: first while performing a reading task which needs sustained attention, and second after treatment, again while performing the same task. The first and second images were compared for each child. Results: There was a statistically significant decrease in regional blood sow in right parietal region and an increase in left temporal region after treatment. Conclusion: Despite methodological saws, this study showed that right anterior parietal region may be important in effects of methylphenidate on attention.
