Amaç: Bu çalışmada dikkat eksikliği hiperaktivite bozukluğu (DEHB) belirtilerinin açıklanmasında yürütücü işlev bozukluklarının önemini vurgulamak amaçlanmıştır. Yöntem: Bu konudaki yayınlar ilk önce Medline'den taranmış, daha sonra aydınlatıcı olduğu düşünülen kiatap ve makaleler gözden geçirilmiştir. Sonuç: Gözden geçirilen yayınarın ortak noktası olarak, farklı tanımlamalara karşın, yürütücü işlevlerin DEHB belirtilerini açıklamasında önemli rol oynadığı görülmüştür. Tartışma: DEHB çocukluk çağının en sık rastlanılan nöropsikiyatrik bozukluğudur. Bu bozukluk ergenlik ve yetişkinlikte de büyük oranda devam etmesi ve çoğunlukla diğer bozukluklarla birlikte görülmesinden dolayı önemlidir. Pek çok kaynakta elde dilen bilgilerde DEHB'de yürütücü işlevlerin bozulmuş olabileceğine ilişkin kanıtlar vardır. Yürütücü işlevler, prefrontal lob yerleşimi olan ve davranışın üst düzey belirleyicisi olduğu düşünülen işlevlerdir. Bu işlevleri ve bozuklukları anlamak, DEHB'nin belirtilerini ve doğal gidişini gözlemlemek klinisyenlere yardımcı olabilir.

Attention Deficit Hyperactivity Disorder and Executive Functions
Objective:The purpose of the study is to state the importance of executive functions for explaining symptomatology of attention deficit hyperactivity disorder (ADHD). Method: First, all the relevant document is searched from Medline, and then the most explanatory documents are taken into account. Results: In spite of diffrent definitions of executive functions, their role in ADHD seems clear. Conclusion: ADHD is the most common neuropsychiatric problem of childhood. This disorder is important because it continues in adolescence and adulthood in a substantial part of patients and it has comorbidity with various disorders. There is evidence from a lot of sources about executive function deficits in ADHD. Executive functions are mediated by prefrontal cortex and are supposed to be the ultimate determinant of behavior. Understanding these functions and their deficits will be helpful for clinicans to observe the symptoms of ADHD and its natural course.
