The term "
" dates back to at least 1949.
Neuroimaging studies of mathematical learning disabilities are still rare but
is an area of increasing interest for neuroscience researchers. Since different neural mechanisms contribute to different elements of mathematical performance, it may be that children with
show variable patterns of abnormality at the brain level. For example, many children with
also have dyslexia, and those that do may show different activation of the verbal networks that support maths, while those who have
only, may show impairments of the parietal number sense system. Indeed, the few studies carried out on children with
only point to a brain level impairment of the number sense system.
can occur in people from across the whole IQ range – often higher than average – along with difficulties with time, measurement, and spatial reasoning. Estimates of the prevalence of
range between 3 and 6% of the population. In 2004, it was reported that a quarter of children with
In 2015, it was established that 11% of children with
also have ADHD.
has also been associated with girls who have Turner syndrome and people who have spina bifida.
In an issue of the "Wolverine" comic, it was stated that Jubilee suffers from
are two learning disorders with different cognitive profiles.
Labels for specific associated issues include visual-spatial deficit,
, dysgraphia, as well as dyspraxia.
Moorcraft takes an active interest in raising awareness of
This suggestion that
is caused by a deficits in a core deficit in number sense is analogous to the theory that dyslexia is due to a core deficit in phonological processing. Despite these similarities in terms of the scientific progress, public awareness of
is much lower than it is for dyslexia. The UK's Chief Scientific Advisor, John Beddington, notes that, "developmental
is currently the poor relation of dyslexia, with a much lower public profile. But the consequences of
are at least as severe as those for dyslexia."
involves frequent difficulties with everyday arithmetic tasks like the following:
Research on subtypes of
has begun without consensus; preliminary research has focused on comorbid learning disorders as subtyping candidates. The most common comorbidity in individuals with
is dyslexia. Most studies done with comorbid samples versus dyscalculic-only samples have shown different mechanisms at work and additive effects of comorbidity, indicating that such subtyping may not be helpful in diagnosing
. But there is variability in results at present.
In some instances, such as Turner syndrome, the onset of
is genetic. Morphological studies have revealed abnormal lengths and depths of the right intraparietal sulcus in individuals suffering from Turner syndrome. Brain imaging in children exhibiting symptoms of
show less gray matter or less activation in the intraparietal regions stimulated normally during mathematical tasks. Additionally, impaired ANS acuity has been shown to differentiate children with
from their normally-developing peers with low maths achievement.
Paulos' article "Counting on
," which appeared in Discover Magazine in 1994, won a Folio Award that year
At its most basic level,
is a learning disability affecting the normal development of arithmetic skills.
LBLD consists of
which comprises the reading of numbers sequentially, learning the time table, and telling time;
The earliest appearance of
is typically a deficit in the ability to know, from a brief glance and without counting, how many objects there are in a small group (see subitizing). Human adults can subitize 3 or 4 objects. However, children with
can subitize fewer objects and even when correct take longer to identify the number than their age-matched peers.
Behavioral studies suggest that the IPS is associated with impairments of basic numerical magnitude processing and that there is a pattern of structural and functional alternations in the IPS and in the PFC in
. Children with developmental
were found to have less gray matter in the left IPS.
A syndrome known as
is seen in individuals who have unexpected difficulty understanding numbers and arithmetic despite adequate education and social environments. This syndrome can manifest in several different ways from the inability to assign a quantity to Arabic numerals to difficulty with times tables.
can result in children falling significantly behind in school, regardless of having normal intelligence levels.
