Environmental Factors in the Etiology of Attention Deficit Hyperactivity Disorder

Abstract

Attention deficit hyperactivity disorder is a heterogeneous neurodevelopmental disorder characterized by inattention, hyperactivity and impulsivity in which genetic, socia land physical factors are influentia land despite the resarches in this field, currently etiology is not fully understood. The aim of this review is to evaluate research on role of environmental factors in the etiology of attention deficit hyperactivity disorder, which is attracting more and more attention all over the world.

Dikkat Eksikliği Hiperaktivite Bozukluğunun Etyolojisinde Çevresel Etkenler

Öz

Dikkat eksikliği hiperaktivite bozukluğu, dikkatsizlik, aşırı hareketlilik ve dürtüsellik belirtileriyle seyreden ve yapılan tüm araştırmalara rağmen halen etiyolojisi tam olarak anlaşılamamış, genetik, sosyal ve fiziksel faktörlerin etkili olduğu heterojen bir nörogelişimsel bozukluktur. Bu yazıda tüm dünyada giderek daha çok ilgi toplayan dikkat eksikliği hiperaktivite bozukluğunun çevresel faktörlerle olan etyolojik ilişkisi hakkında yürütülmüş araştırma sonuçlarının değerlendirilmesi hedeflenmiştir.

Anahtar Kelimeler
