Dikkat Eksikliği Hiperaktivite Bozukluğu Epidemiyolojisi
TU Özaslan, Ö Bilaç
Isparta Kadın Doğum ve Çocuk Hastalıkları Hastanesi, Isparta
Dikkat eksikliği ve hiperaktivite bozukluğu (DEHB) dikkatsizlik, hiperaktivite ve dürtüsellik belirtileri ile karakterize, çocukluk çağının en sık görülen psikiyatrik hastalıklarından birisidir. Dünyada yapılan çalışmalar gözden geçirildiğinde, okul çağı çocuklarında %0,2-%0,4 gibi çok düşük değerlerden %23,4-%27 gibi daha yüksek değerler arasında oldukça farklı prevalans oranları görülmektedir. Bazı araştırmacılar bozukluğun bir Amerikan hastalığı olduğunu, Amerikan toplumunda daha sık olan sosyal ve kültürel özelliklerden kaynaklanabileceğini ve dünyanın diğer bölgelerinde çok daha az sıklıkla görüldüğünü öne sürmektedir. Son yıllarda yapılan oldukça önemli iki meta analiz çalışmasına göre, DEHB'nin tüm dünyadaki ortalama prevalansı %5,29 ve %5,9-7,1 olarak bulunmuş ve dünyada DEHB sıklığındaki büyük farklılıkların, temelde çalışmalarda kullanılan metodolojik özelliklerden olduğu gösterilmiştir. DEHB prevalans çalışmalarının az olduğu bölgelerden daha çok kapsamlı çalışma yapılmasına ihtiyaç olduğu açıktır. Bu yazıda DEHB epidemiyolojisinin literatür ışığında gözden geçirilmesi amaçlanmıştır.
Epidemiological Aspect of Attention Deficit Hyperactivity Disorder
Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorder of childhood which is characterized by symptoms of inattention, hyperactivity and impulsivity. A huge variability in prevalence rates is detected among studies in the world, ranging from as low as 0.2%-0.4% to as high as nearly 23.4%-27%. Some researchers suggest that ADHD is largely an American disorder, perhaps stemming from social and cultural factors which are more common in American society and is much less prevalent elsewhere. The worlwide pooled prevalence of ADHD was estimated to be 5.29% and 5.9-7.1% according to two quite important meta-analytical reviews in recent years and these reviews suggest that the large variability of worldwide ADHD prevalence rates is associated with methodological differences among studies. It is obvious that the large scale epidemiological studies of ADHD are needed from the regions where ADHD epidemiology were less studied. The aim of this article is to review epidemiologic aspects of ADHD in the light of the literature.
