Dikkat Eksikliği Hiperaktivite Bozukluğu Etiyolojisinde Genetik, Nörolojik ve Perinatal Etkenlerin Önemi
ES Ercan, İ Erdoğan, M Tamar
Son yıllarda Dikkat Eksikliği Hiperaktivite Bozukluğuna (DEHB) verilen önem gözle görülür bir biçimde artmaktadır. DEHB konusunda yapılan araş tımıalar içerisinde bozukluğun etiyolojisinin belirlenmesine yönelik olanlar oldukça büyük bir yer tutmaktadır. Bozukluğun tanımlanmasından beri DEHB etiyolojisi ile ilgili olarak nörolojik etkenler üzerinde durulmaktadır. Özellikle 1980'li yılların sonlarından itibaren ileri beyin görüntüleme yöntemlerinin kullanılmaya başlaması bu araştırmaların-büyük bir hızla artmasını sağlamıştır. Benzer biçimde, 1970'li yıllarda başlayan genetik araştımıalarda DEHB etiyoloj isiyle ilgili önemli bulgulara ulaşılması ve tıbbın tüm alanlarında genetik araştırmalara ağırlık verilmesi, I980'li yıllardan başlayarak DEHB'de genetik çalışmaların önemini ve sıklığını arttırmıştır. Diğer yandan ilerleyen tıbbi teknoloji sonucu perinatal olayların ayrıntılı bir biçimde irdelenebilmesi tüm hastalıklarda olduğu gibi DEHB'de de ilgi uyandırmıştır. Bu konuda yapılan araştımıalarda da DEHB etiyolojisinin aydınlatılması konusunda önemli bulgulara ulaşılması konuya verilen önemi arttırmıştır.
Bu yazıda DEHB etiyoloj isiyle ilgili araştımıalarda oldukça gündemde olan genetik, nörolojik ve perinatal etkenleri araştıran çalışmalar gözden geçirilmiştir.
