Brain Gray Matter Deficits at 33-Year Follow-up in Adults With Attention-Deficit/Hyperactivity Disorder Established in Childhood

In the paper

“Both remitters and persistents had thinner cortex than non-ADHD comparisons, with medium to large effect sizes.”

In the paper

“As shown in eFigure 1 and Author e-Table 6, after covarying for IQ (in addition to scanner and age), significant cluster centers remained largely unchanged in location, but the clusters were less extensive.”

In the paper

“However, scanned probands had significantly higher rates of alcohol substance use disorder (SUD), non-alcohol SUD, and any SUD than probands who were not scanned (Author e-Table 3)”

In the paper

“Using FDR<0.05, remitters (n=26) did not differ significantly from non-ADHD comparisons; persistents and remitters also did not differ in any region at this threshold.”

In the paper

“Figure 1A displays the multiple clusters of vertices (detailed in Table 2) for which the cortex was significantly thinner (surface-wide FDR<0.05) in ADHD probands; the largest cluster extended from right precuneus to precentral gyrus.”

In the paper

“Average effect sizes between persistents and non-ADHD comparisons (d=0.73) were larger than for remitters (d=0.52), although all confidence intervals overlapped (not shown); persistents and remitters did not differ significantly from each other in any cluster at FDR<0.05 (see Table 2).”

In the paper

“Due to refusals and MRI exclusions (see Table 1), we obtained MRI scans in 59 ADHD probands and 80 comparisons.”

In the paper

“There were no vertices at which cortical thickness was significantly associated with lifetime or current substance abuse diagnoses, dimensional measures of substance abuse, lifetime smoking history, or thioridazine treatment, nor were there any significant interactions between group and scanner for any cortical or VBM measures.”

In the paper

“probands and comparisons with current ADHD-NOS, which is not well-defined and did not differ between groups (27% and 29%, respectively), were excluded from subgroup analyses.”

In the paper

“On average 33 years after initial childhood diagnosis, clinical data were obtained on 135 male probands (65% of original sample, 69% of those living) and 136 male comparisons (76% of 178 recruited in adolescence, 77% of those living).”

In the paper

“Within both proband and comparison groups, individuals scanned and those not scanned did not differ significantly on prevalence of ADHD, Antisocial Personality Disorder, mood or anxiety disorders, any DSM-III disorders, age at referral, IQ, socioeconomic status, or Teacher Conners Hyperactivity Factor score.”

In the paper

“Probands and comparisons did not differ significantly in age at scan, or in lifetime prevalence of substance abuse or dependence (see Table 1).”

In the paper

“As expected, probands and comparisons differed significantly in IQ in childhood and 41FU assessments.”

In the paper

“By contrast, rates of refusal, failure to schedule or to locate subjects did not differ significantly (45% of probands versus 43% of comparisons).”

In the paper

“As shown in Table 3 and Figure 3, GM density was significantly greater (FDR<0.05) for comparisons than for probands in many of the same regions identified through cortical thickness analyses as well as in subcortical regions inaccessible to cortex-based measures.”

In the paper

“In the clusters that differentiated persistents from remitters in exploratory vertex-wise analyses, persistents differed markedly from non-ADHD comparisons (average d=0.75), whereas remitters did not (average d=0.03; t(9)=8.26, p<0.0001).”

In the paper

“We found similar results in analyses that included all participants as well as in those limited to probands with persistent ADHD versus non-ADHD comparisons.”

In the paper

“With respect to current adult diagnosis, probands with persistent ADHD differed most from non-ADHD comparisons in the same cortical regions identified in our primary analyses, as well as in additional clusters in left medial occipital cortex and subgenual ACC.”

In the paper

“In a prospective 33-year longitudinal follow-up of 59 probands (mean age 41 years) with established ADHD in childhood and 80 prospectively enrolled non-ADHD comparisons, we found an overall significant reduction in mean cortical thickness in probands.”

In the paper

“In contrast, we did not find group differences in much of prefrontal cortex but found widespread cortical thinning in bilateral parietal-temporal cortex.”

In the paper

“Figure 4 displays decreased GM in probands in right caudate, right thalamus and bilateral cerebellar hemispheres.”

In the paper

“First, we found widespread thinner cortex and decreased GM density in bilateral parietal and precentral regions, overlapping areas of the dorsal attentional network.”

In the paper

“Second, our analyses revealed thinner cortex in probands, and particularly those with persistent ADHD, across multiple limbic regions such as temporal poles (BA38), insula (BA13) and subgenual ACC (BA25).”

In the paper

“our probands had significantly lower IQ than comparisons both in childhood/adolescence and adulthood.”

In the paper

“In regions in which we found suggestive differences, we observed remarkable congruence between remitters and controls in left superior temporal gyrus, ACC, parahippocampus, and occipital cortical thickness as well as in thalamus and cerebellum gray matter density.”

In the paper

“We observed thinner cortex in regions subserving both emotional regulation (temporal pole, insula, parahippocampus and subgenual ACC) and top-down attentional regulation (dorsal attentional network and medial occipital cortex).”

In the paper

“there were no significant main effects or interactions related to scanner type.”

In the paper

“These findings were largely echoed by VBM, which additionally highlighted decreased GM in caudate.”

In the paper

“treatment had been discontinued for all subjects for several decades.”

In the paper

“we found thinner overall cortex in probands with childhood ADHD that was even more pronounced in those with persistent ADHD.”

In the paper

“The diagnosis of ADHD requires onset in childhood, but persistence of ADHD into adulthood is now well documented.4, 5”
