Obviously the attention deficit is responsible for "per se" of learning difficulties since the beginning of the preschool stage, but it is also frequent to find children, in which their teachers do not get the way to advance in the learning of any of the school instrumental techniques (reading, writing and calculating). They are patients who present at a comorbid level what the neuropediatric partner J. Artigas calls " learning disorders ".
According to various studies, the percentage of ADHD children and adolescents with learning disabilities reaches 60% ( Green. M. et al 1999). Accordingly, we can hypothesize that children or adolescents with attention-deficit / hyperactivity disorder, inattentive type, most likely reach higher percentages ( Rodríguez Salinas E.et in 2006 ).
Learning Disorders Associated with ADHD
The most common comorbid learning disorders are disorders of reading, spelling, writing, and calculus, also called dyslexia, dysortography, dysgraphia, and dyscalculia.
The most significant difficulties as a prognostic factor in school learning are the readers. At this level, the presence of difficulties in phonetic segmentation (ability to decompose words into sounds), visual reading (recognition of letters and words by their form) and reading comprehension are highlighted in these children.
Inattentive children usually present difficulties in their acquisition of lectomechanics (reading speed) without making the reading comprehension problems too evident; when they do present and are relevant we must always raise a comorbid dyslexic disorder , other aspects that we frequently encounter among the difficulties of schooling. the inattentive children are their deficits in written expression and the presence of a significant dysortography.
