“…Persistence of symptoms has been demonstrated in several longitudinal investigations from independent research groups (Campbell et al 1986;Lahey et al 2004;Lahey et al 1998;McGee et al 1991). Academic, social, and global impairment as reported by teacher and parent measures have been reported both cross-sectionally and longitudinally (Gadow et al 2001;Kadesjo et al 2001;Lahey et al 2004;Tandon et al 2009). The level of impairment of preschoolers with ADHD, has been reported to be similar to that of affected school age children (Wilens et al 2002).…”

“…Further, other symptoms that are common and developmentally normative, such as ''often interrupts,'' occur at much higher rates in preschoolers with ADHD . For example, rates of ADHD symptom levels were reported as 4-8 times higher in clinic referred preschoolers with ADHD compared to age matched, non-ADHD preschoolers in a study of 3 to 7 year old children (Kadesjo et al 2001). …”

Objective: The present study examined the course of ADHD over 24 months in a preschool population. Method: n = 48 preschoolers with ADHD, aged 3.0-5.11 years, subjects included in a larger sample of preschoolers with depression and other disorders (n = 306) were comprehensively assessed at 3 annual time points over 24 months in a prospective longitudinal follow-up study. Results: Baseline diagnoses of preschool MDD, ODD, and CD were risk factors for ADHD diagnosis over 24 months in this preschool population. Among older preschoolers and after controlling for key demographic variables, ADHD predicted later ADHD diagnosis, along with other significant risk factors -baseline diagnosis of ODD, and/or family history of disruptive disorders, and stressful life events. Conclusions: ADHD showed greater homotypic continuity at later rather than earlier preschool ages. Other disruptive comorbidities also emerged as key predictors of stable ADHD course. Study findings may help to inform which preschool ADHD populations to target for early intervention. Larger sample sizes are needed to confirm these findings and to further explore the stability, course, and predictors of outcome of preschool onset ADHD.

“…Here we report raw scores only, since Norwegian norms have not yet been developed, and it has been found that Nordic parents seem to assess their children similarly on the CBCL, but consistently lower than parents in other countries (Nøvik, 1999). The Attention Problems subscale of the CBCL is effective in identifying children with clinically diagnosed ADHD (Kadesjø et al, 2001). …”

Volumetric cerebral characteristics of children exposed to opiates and other substances in utero

et al. 2007

Morphometric cerebral characteristics were studied in children with prenatal poly-substance exposure (n =14) compared to controls (n = 14) without such exposure. Ten of the substance exposed children were born to mothers who used opiates (heroin) throughout the pregnancy. Groups were compared across 16 brain measures: cortical gray matter, cerebral white matter, hippocampus, amygdala, thalamus, accumbens area, caudate, putamen, pallidum, brainstem, cerebellar cortex, cerebellar white matter, lateral ventricles, inferior lateral ventricles, and the 3 rd and 4 th ventricles. In addition, continuous measurement of thickness across the entire cortical mantle was performed. Volumetric characteristics were correlated with ability and questionnaire assessments 2 years prior to scan. Compared to controls, the substance-exposed children had smaller intracranial and brain volumes, including smaller cerebral cortex, amygdala, accumbens area, putamen, pallidum, brainstem, cerebellar cortex, cerebellar white matter, and inferior lateral ventricles, and thinner cortex of the right anterior cingulate and lateral orbitofrontal cortex. Pallidum and putamen appeared especially reduced in the subgroup exposed to opiates. Only volumes of the right anterior cingulate, the right lateral orbitofrontal cortex and the accumbens area, showed some association with ability and questionnaire measures. The sample studied is rare, and hence small, so conclusions cannot be drawn with certainty. Morphometric group differences were observed, but associations with previous behavioral assessment were generally weak. Some of the volumetric differences, particularly thinner cortex in part of the right lateral orbitofrontal cortex, may be moderately involved in cognitive and behavioral difficulties more frequently experienced by opiate and poly-substance exposed children.

“…In their research, behaviour problems as an associated disorder with ADHD fell to a level which does not differ statistically significantly from the children in the general population. The results obtained indicate the possibility that behaviour disorders may be an indicator or marker of the severity of symptoms of ADHD (51,60).…”
