Nonverbal learning disorder

Considered to be neurologically based,[1][2][3] nonverbal learning disorder, otherwise known as nonverbal learning disability (NLD or NVLD), is characterized by verbal strengths as well as visual-spatial, motor and social skills deficits. [4][5] People with this disorder may not perceive nonverbal cues such as facial expression or tone of voice.[6] Challenges with mathematics and handwriting are typical.[7]

While "nonverbal" (perceptual/cognitive and motor) impairments were recognized since early studies in child neurology,[8][9][10][11] there is on-going debate as to whether/or the extent to which existing conceptions of NLD provide a valid diagnostic framework. As originally presented "disorders of nonverbal learning" was a category encompassing primarily non-linguistic learning difficulties (Johnson and Myklebust, 1967)[12] and then "nonverbal learning disabilities" was discussed as a type of learning disability with various sub-types (Myklebust,1975).[13] Later neuropsychologist Byron Rourke [14] sought to define a clinically discrete NLD syndrome employing a specific theory of brain functioning (1989).[15]

In light of emerging neuroscientific research, questions remain about how best to frame the perceptual, cognitive and motor issues associated with NLD.[16][17][18]

The DSM-5 (Diagnostic and Statistical Manual) and ICD-10 (International Classification of Diseases) do not include NLD as a diagnosis.[19][20]
