We also found increasedright nucleus accumbens volume in SC users without ADHD, but notwith ADHD, compared to controls.Conclusion: These results suggest that similar to cannabis use, SC use hasalso negative effects on brain morphology and comorbidity of ADHDand substance dependence may show different cortical thickness andsubcortical volume alterations than substance use alone.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Introduction: Synthetic cannabinoids (SCs) have become increasinglypopular in the last few years, especially among adolescents.
📊
Key Findings & Data:GivenAttention deficit/hyperactivity disorder (ADHD) is over represented inpatients with substance use across adolescents compared to the generalpopulation, the current study aims were two-fold: i) examine corticalthickness, surface area and subcortical volumes in SC users compared tocontrols, ii) examine the influence of ADHD on cortical thickness, surfacearea and subcortical volumes in SC users.Methods: Structural magnetic resonance imaging scans were acquiredfrom 28 SC users (15 without ADHD and 13 with ADHD combined type)and 13 controls.Results: We found that SC users both with and without ADHD groupshave significantly reduced cortical thickness compared to controlsin areas of the left caudal middle frontal and left superior frontal.

Abstract

Introduction: Synthetic cannabinoids (SCs) have become increasinglypopular in the last few years, especially among adolescents. GivenAttention deficit/hyperactivity disorder (ADHD) is over represented inpatients with substance use across adolescents compared to the generalpopulation, the current study aims were two-fold: i) examine corticalthickness, surface area and subcortical volumes in SC users compared tocontrols, ii) examine the influence of ADHD on cortical thickness, surfacearea and subcortical volumes in SC users.Methods: Structural magnetic resonance imaging scans were acquiredfrom 28 SC users (15 without ADHD and 13 with ADHD combined type)and 13 controls.Results: We found that SC users both with and without ADHD groupshave significantly reduced cortical thickness compared to controlsin areas of the left caudal middle frontal and left superior frontal. Inaddition, SC users with ADHD also showed reduced cortical thicknessin the right precentral and postcentral gyruses. We also found increasedright nucleus accumbens volume in SC users without ADHD, but notwith ADHD, compared to controls.Conclusion: These results suggest that similar to cannabis use, SC use hasalso negative effects on brain morphology and comorbidity of ADHDand substance dependence may show different cortical thickness andsubcortical volume alterations than substance use alone.

Özet

Giriş: Başta ergenler arasında olmak üzere, son yıllarda sentetik kannabinoid (SK) kullanımı giderek artmaktadır. Dikkat eksikliği ve hiperaktivite bozukluğunun (DEHB) madde kullanım bozukluğu olanlarda genel popülasyondan daha sık görüldüğü dikkate alınarak, bu çalışmada DEHB eştanısı olan ve olmayan SK kullanıcılarının kortikal kalınlık, yüzey alanı ve subkortikal hacimlerinin kontroller ile karşılaştırılması amaçlanmıştır. Yöntem: 28 SK kullanıcısı (13 DEHB eş tanısı olan ve 15 olmayan) ile 13 kontrolün yapısal beyin görüntüleri karşılaştırılmıştır. Sonuçlar: DEHB eştanısı olan ve olmayan SK kullanıcılarının sol kaudal frontal ve sol superior frontal korteks de kontrollere göre daha düşük kortikal kalınlık gösterdikleri saptanmıştır. DEHB eş tanısı olan grup kontrollerle karşılaştırıldığında sağ pre-, post-santral gyrus’larda kortikal kalınlık azalması göstermiştir. Ayrıca, DEHB eş tanısı olmayan grupta da nükleus akumbens hacminde artış saptanmıştır. Tartışma: Sonuçlarımız SK kullanımının beyin morfolojisi üzerine olumsuz etkileri olduğunu ve ayrıca DEHB eştanısı olan madde kullanım bozukluğu hastalarının eştanısı olmayanlara göre farklı beyin morfolojik özellikleri gösterebileceğini düşündürtmektedir.
