“…AD/HD is one of the most widespread childhood psychiatric conditions, with epidemiological studies estimating a prevalence of between 5% and 10% (Faraone et al, 2003;Polanczyk et al, 2007;Skounti et al, 2007).…”

Demanding tasks require a greater amount of effort, in which case individuals are required to alter their energetic-state to a level appropriate to perform the task. According to the Cognitive-Energetic Model (CEM), children with AD/HD are unable to effectively modulate their energetic state, leading to task underperformance. Using an Eriksen flanker task with varying event-rates, the current study compared the ability of typically-developing children and children with AD/HD to modulate their energetic state. In line with the CEM, it was predicted that children with AD/HD would underperform in the fast and slow eventrates. Results indicated that the groups did not differ in commission errors (i.e., incorrect responses). However, children with AD/HD made more omission errors to incongruent stimuli at the fast and slow eventrates, compared to controls. N2 amplitude was significantly larger for the AD/HD than control group in the slow event-rate. It is concluded that the energetic state modulation dysfunction in children with AD/HD results in an inability to attend to the task, as opposed to an inability to perform the task itself. Furthermore, these task performance differences did not manifest in either the N2 or P3 ERP components. Therefore, inattention in children with AD/HD may have its locus in response preparation, as opposed to stimulus processing, but more research is required to validate these conjectures.

Results indicated that the groups did not differ in commission errors (i.e., incorrect responses). However, children with AD/HD made more omission errors (i.e., impulsively early or non-responses) to incongruent stimuli at the fast and slow event-rates, compared to controls. N2 amplitude was significantly larger for the AD/HD than control group in the slow event-rate. It is concluded that the energetic state modulation dysfunction in children with AD/HD results in an inability to attend to the task, as opposed to an inability to perform the task itself.

Background: Attention deficit hyperactivity disorder (ADHD) is the most common mental disorder in the pediatric population and affects education, finances, and medication. ADHD diagnostic criteria and resultant prevalence rates are also of special interest to the global psychiatric community. ADHD diagnosis rates and the corresponding demographic distributions through different years are thus an issue of great public health concern and debate. The objective of this study is to characterize changes in the demographic distribution of ADHD diagnosis from 2004 to 2012 in the United States. Methods: ADHD diagnosis data was extracted from the National Health and Nutrition Examination Survey (NHANES) Summary Health Statistics for United States Children, a source of nationally representative data on children in the United States. The ADHD cases were identified based on ICD9-CM diagnosis codes. Chi-square tests were used to investigate differences in ADHD diagnosis rates by demographic characteristics (age, race, and gender) within each year and simple linear regression was applied to determine the extent of change over time. Results: The ADHD diagnosis rate was higher among males, whites, and school-aged children and adolescents (vs. preschoolers aged 3-4) in each year examined. The total number of ADHD cases as well as all demographic groups with the exception of African Americans and preschoolers aged 3-4 exhibited an increasing trend between 2004 and 2012. Conclusions: ADHD diagnosis among youth showed a significant increase in the United States between 2004 and 2012. Notable increases and group differences were also observed among demographic subgroups. These findings indicate a need for future research in reasons for such group differences as well as treatment differences.

ÖzetPanik Bozukluğu (PB) olan hastalarda diğer psikiyatrik hastalıkların eş tanı oranı oldukça yüksektir. Bu çalışmada panik bozukluğu tanısı almış erişkinlerde Dikkat Eksikliği ve Hiperaktivite Bozukluğu (DEHB) varlığı ve bu durumla ilişkili özellikler araştırılmıştır. Çalışmamıza psikiyatri polikliniğine başvuran ve SCID-I ile DSM-IV 'e göre PB tanısı almış 65 kişi ile kontrol grubunu oluşturan 65 sağlıklı gönüllü alınmıştır. Hasta grubunun hastalık şiddeti ve klinik durumlarının belirlenebilmesi amacıyla bu gruba Panik-Agorafobi Ölçeği uygulanmıştır. Klinik görüşmelere ek olarak her iki gruptan Sosyodemografik Veri Formu doldurulması istenmiş, WUDÖ ile Erişkin DEB/DEHB Tanı ve Değerlendirme Ölçeği uygulanmıştır. Çalışmamızda PB tanısı alan hastaların büyük çoğunluğunu kadın hastaların oluşturmaktadır. "İşsiz olma-çalışmama" durumunun sağlıklılara göre istatistiksel olarak anlamlı şekilde fazla olduğu gözlenmiştir. Çalışma ve kontrol grubu arasında yaş ortalamaları, medeni durum ve eğitim durumlarının dağılımı açısından istatistiksel olarak anlamlı bir fark tespit edilmemiştir. PB tanısı alan hastalarda şu anki DEHB eş tanı oranı %15,4 olarak bulunmuştur. DEHB eş tanılı hastalarda DEHB alt tiplerinin grup içindeki dağılımları %60 'ı bileşik tip, %20' si " hiperaktivite ve dürtüsellik ", %20' si " dikkat eksikliği " önde olan şeklinde saptanmıştır. Agorafobisi olan hastaların tamamında DEHB eş tanısı bulunmuştur. PB ile DEHB eş tanısı alan grupta panik bozukluğu olmadan DEHB tanısını alan gruba oranla daha düşük iş devamlılığı gözlenmiştir. DEHB tanılı hastalarda çalışma ve kontrol grubu arasında alkol kullanımı açısından istatistiksel bir farka rastlanmamıştır. 40 yaş üstü grupta DEHB hiç tespit edilmemiştir. Çalışmamızda PB ile DEHB eş tanı oranının sağlıklı kontrollerden yüksek olduğu, agorafobisi olan PB olgularının tamamında DEHB eş tanısının bulunduğu görülmektedir.

This study aims to investigate the comorbid Attention Deficit and Hyperactivity Disorder (ADHD) with panic disorder (PD) in adults. In this study, 65 people with a diagnosis of panic disorder and 65 healthy volunteers who admitted to outpatient psychiatry clinic were included. In order to determine the disease severity and current clinical state Panic Agoraphobia Scale was used. Sociodemographic information form, Wender Utah Rating Scale (WURS) and Adult ADHD Diagnosis and Assessment Scale was used. Diagnosis of PD was significantly higher in women. Also it was observed that unemployment was statistically higher in PD group. There was no difference observed in between mean ages, marital status and education level. In patients diagnosed with panic disorder ADHD comorbidity rate was 15,4%. In comorbidity cas...
