Abstract: Previous research has demonstrated that there are specific white matter abnormalities in patients with attention deficit/hyperactivity disorder (ADHD). However, the results of these studies are not consistent, and one of the most important factors that affects the inconsistency of previous studies maybe the ADHD subtype. Different ADHD subtypes may have some overlapping microstructural damage, but they may also have unique microstructural abnormalities. The objective of this study was to investigate the micros… Show more

“…Particular involvement of fronto-limbic pathways (cingulum bundle) in ADHD-C aligns with previous DTI[Lei et al, 2014; Nagel et al, 2011] and resting-state findings[Fair et al, 2012] and might represent a structural substrate of executive functions and sustained attention deficits[Chiang et al, 2015; Kubicki et al, 2003] in ADHD-C. On the other hand, ADHD-PI preferentially demonstrated disturbances in fronto-striato-thalamic circuits that are implicated in cognitive control,[Fair et al, 2012] processing speed[Rossi et al, 2015] and selective attention,[Wright et al, 2015] indicative of ADHD-PI. In addition, disruptions in occipito-temporal, fronto-limbic and corticospinal connections might add to other features of abnormal executive functioning in ADHD-PI.…”

“…One study, which estimated DTI parameters in ADHD-C and ADHD-PI separately, introduced evidence of differences in white matter organization between typically developed children and the two main ADHD presentations. [Lei et al, 2014] Hong et al revealed decreased structural connectivity in ADHD-C comparing to ADHD-PI using network-based analysis in the neuronal circuits in the right hemisphere. [Hong et al, 2014]…”

“…Additionally, since calculation of the reward anticipation condition did not exclude incorrect or omitted trials but the reward attainment condition did, inattention could potentially account for some of the observed differences between the two conditions. For example, studies have found associations between inattention and the cuneus, precuneus, and temporo-occipital circuits (Lei et al, 2014), particularly in ADHD samples, a co-morbid diagnosis also present in some of our participants. Therefore, it is possible that activation of these regions in the anticipation vs. attainment contrast could be due to inattention.…”

“…Since one of two datasets in Cortese et al., recruited individuals with a current ADHD diagnosis, the study was included in the analysis (Cortese et al., ). On the other hand, 13 studies with 14 datasets with 314 individuals with ADHD and 278 TD participants were eligible for the WBVBA meta‐analysis (Ashtari et al., ; Chaim et al., ; Chen et al., ; Choi et al., ; Davenport, Karatekin, White, & Lim, ; De Zeeuw et al., ; Kobel et al., ; Konrad et al., ; Lei et al., ; Li et al., ; Malisza et al., ; Peterson et al., ; Qiu et al., ).…”
