Abstract

Objective: Event related brain potentials (ERPs) is a noninvasive technique giving knowledge about neural activity associated with sensory and cognitive information processing. The aim of this paper is to review investigations which used ERPs technique in attention deficit hyperactivity disorder (ADHD). Method: Selected papers and books regarding to auditory event related potentials and ADHD are reviewed, and the results are summarized. Fourty four scientific paper, and four books are used to write this paper. Results: Smaller amplitude ofP, in children with ADHD compared to normal controls may reflect a problem with states of arousal related to locus cereleus and norepinephrinergic system. Smaller N2 may suggest that children with ADHD were not good at signal detection and discrimination. This situation may show a failure in frontal inhibition process. Especially, the effect ofNE on alfa-2 receptors seems to be important in inhibition. Smaller P3 in children with ADHD may demonstrate a problem with allocation of attention and ineffective working memory updating. Prefrontal cortex possibly affects working memory function via GABA, dopamine, norepinephrine, and acetylcholine neurotrans-mitters. Discussion: ERPs studies which take confusing factors such as age, comorbidity, gender, and type of ADHD into consideration may provide both a better understanding of in formation processing in ADHD and insight into pathophysiology of ADHD.

Özet

Amaç: Olayla ilgili potansiyeller (ERPs) merkezi sinir sisteminde duyusal ve bilişsel bilgi işlemeyle ilgili bilgi veren invazif olmayan bir tekniktir. Bu yazının amacı, dikkat eksikliği hiperaktivite bozukluğunda (DEHB), ERPs tekniğiyle yapılan araştırmaları gözden geçirmektir. Yöntem: Bu çalışmada, DEHB ve ERPs ile ilgili olarak seçilen kitap ve yazılar gözden geçirildi, sonuçları özetlendi. Bu derlemenin yazılması için, kırk dört bilimsel yazıdan ve dört kitaptan yararlanılmıştır. Sonuçlar: DEHB olan çocukların, normal kontrollere göre, P1 amplitüdünün küçük olması lokus sereleus-norepinefrinerjik sistemini ilgilendiren uyarılma ile ilgili bir sorunu yansıtabilir. N2 dalgasındaki küçüklük, DEHB olan çocukları n uyaranın tespiti ve ayırımındaki zorluğu düşlündürebilir. Bu durum DEHB’da frontal inhibisyon sürecinde yetersizliği gösterebilir. Özellikle norepineşrinin postsinaptik alfa-2 reseptörlerine olan etkisi inhibisyonda önemli gibi görünmektedir. DEHB’daki çocuklarda P3 dalgasındaki küçüklük, dikkatin yönlendirilmesindeki (allocation) bir soruna ve işleyen belleğin yenilenmesindeki yetersizliğe işaret edebilir. Prefrontal korteks GABA, dopamin, norepinefrin, serotonin, asetilkolin, norotransmitterleri aracılığıyla işleyen bellek işlevlerini gerçekleştirmektedir. Tartışlma: DEHB’da, yaş, komorbidite, cinsiyet, DEHB’nun tipi gibi karışltırıcı etkenler göz önünde tutularak yapılacak daha ileri ERP çalışmaları, DEHB’daki bilgi işlleme sürecinin anlaşılmasını ve DEHB’nun patofizyolojisinin aydınlatılmasını sağlayacaktır.
