ADHD and Dyscalculia: Evidence for Independent Familial Transmission

Posted on by

News from the web:

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.

Developmental dyscalculia: prevalence and demographic features.

News from the web:

Abstract

One hundred and forty-three 11-year-old children with development dyscalculia, from a cohort of 3029 students, were studied to determine demographic features and prevalence of this primary cognitive disorder. They were evaluated for gender, IQ, linguistic and perceptual skills, symptoms of attention-deficit hyperactivity disorder (ADHD), socio-economic status and associated learned disabilities. The IQs of the 140 children (75 girls and 65 boys) retained in the study group (three were excluded because of low IQs) ranged from 80 to 129 (mean 98.2, SD 9.9). 26 per cent of the children had symptoms of ADHD, and 17 per cent had dyslexia. Their socio-economic status was significantly lower than that of the rest of the cohort, and 42 per cent had first-degree relatives with learning disabilities. The prevalence of dyscalculia in the original cohort was 6.5 per cent, similar to that of dyslexia and ADHD. However, unlike these other learning disabilities, dyscalculia affected the two sexes in about the same proportions.

The mathematics surrounds our lives, a fact of life. Our children sometimes just do not experience such an important element of the mathematics. But the theories are born from practical experience.

The Psychology of Dyscalculia

Posted on by

News from the web:

Dyscalculia is defined as a specific learning difficultyaffecting a person’s ability to understand and/or manipulate numbers. Like dyslexia, dyscalculia can be caused by a visual perceptual deficit. Dyscalculia is often used to refer specifically to the inability to perform operations in math or arithmetic, but is defined by some educational professionals as a more fundamental inability to conceptualize numbers themselves as an abstract concept of comparative quantities. It is a lesser known disability, much like dyslexia anddyspraxia. In fact, it is considered by some to be a variation of dyslexia.
