TLDR
The hypothesis that ADHD and dyscalculia are independently transmitted in families and are etiologically distinct is supported and the need for separate identification and treatment strategies for children with both conditions is underscore.Abstract:
The familial relationship between dyscalculia and attention-deficit/hyperactivity disorder (ADHD) was assessed. We conducted a familial risk analysis using probands with and without ADHD of both genders and their first-degree relatives. Participants were assessed with structured diagnostic interviews and a cognitive test battery. We found elevated rates of ADHD in relatives of both ADHD proband groups, regardless of dyscalculia status, and elevated rates of dyscalculia in relatives of probands with dyscalculia, irrespective of ADHD status. There was no evidence for cosegregation or assortative mating. Our findings support the hypothesis that ADHD and dyscalculia are independently transmitted in families and are etiologically distinct. These results reinforce the current nosological approach to these disorders and underscore the need for separate identification and treatment strategies for children with both conditions.read more

TL;DR: The neural bases of numerosity processing have been investigated in structural and functional neuroimaging studies of adults and children, and neural markers of its impairment in dyscalculia have been identified.

Understanding Neurocognitive Developmental Disorders Can Improve Education for All
TL;DR: The complex etiology of SLDs and their co-occurrences need to be understood in order to underpin the training of teachers, school psychologists, and clinicians, so that they can reliably recognize S LDs and optimize the learning contexts for individual learners.

Longitudinal data analysis using generalized linear models

TL;DR: In this article, an extension of generalized linear models to the analysis of longitudinal data is proposed, which gives consistent estimates of the regression parameters and of their variance under mild assumptions about the time dependence.

Adult Outcome of Hyperactive Boys: Educational Achievement, Occupational Rank, and Psychiatric Status
TL;DR: The adolescent outcome of this cohort found that these disturbances were dependent on the continuation of ADHD symptoms, and in adulthood, antisocial and drug disorders appeared, in part, independent of sustained ADHD.
