Children with Learning Disorders process information
differently. Learning Disorders are caused by a faulty brain
system, either in the structure of the brain or the functioning
of different chemicals. Underlying abnormalities in cognitive
processing (e.g., deficits in visual perception, linguistic
processes, attention, or memory, or a combination) often precede
or are associated with Learning Disorders. Genetic
predisposition, perinatal injury, and various neurological or
other general medical conditions may be associated with Learning
Disorders, but the presence of such conditions does not
necessarily predict a Learning Disorder. Learning Disorders are,
however, frequently found in association with a variety of
general medical conditions (e.g., lead poisoning, fetal alcohol
syndrome, or fragile X syndrome).
