How do the biological causes of language-based learning disabilities and nonverbal learning disabilities differ?

What will be an ideal response?

SLD with impairment in written expression as well, are associated with brain deficits that differ from those described for language-based learning disorders. These deficits are largely found in areas not related to verbal ability, which has led to the term nonverbal learning disability. Nonverbal learning disability (NLD) is associated with deficits related to right-hemisphere brain functioning, which are characteristic of children who perform considerably worse at math than reading. These deficits involve social/emotional skills, spatial orientation, problem solving, and the recognition of nonverbal cues such as body language (Hulme & Snowling, 2009). In addition to math deficiencies, NLD may be accompanied by neuropsychological problems such as poor coordination, poor judgment, and difficulties adapting to novel and complex situations.
