Nonverbal learning disorder Information & Nonverbal learning disorder Links at HealthHaven.com

Nonverbal learning disorder or nonverbal learning disability (NLD or NVLD) is a proposed condition characterized by a significant discrepancy between high verbal and lower performance scores on an IQ test, with deficits in motor, visual-spatial, and social skills.^[1] Some proponents of the category believe that this discrepancy is attributable to dysfunction in the right cerebral hemisphere.^[1]^[2]

NLD involves deficits in perception, coordination, socialisation, non-verbal problem-solving and understanding of humour, along with well-developed rote memory.^[3] As most people with Asperger syndrome (AS) fit the criteria for NLD, a diagnosis of AS is often preferred.^[3] In this instance, some researchers assert that an AS diagnosis is more clinically useful than an NLD diagnosis, and argue that NLD would be an example of excessive diagnostic splitting. However, NLD can also occur with other disorders. ^[3]
