Nonverbal learning disorder or nonverbal learning disability (NLD or NVLD) is a neurological disorder characterized by a significant discrepancy between higher verbal skills and lower motor, visuo-spatial, and social skills on an IQ test.
Ongoing debate surrounds the relationship between Asperger syndrome and NLD, as research on the condition is ongoing and procedures can differ from AS research. Although most people with Asperger syndrome (AS) fit the criteria for NLD, a diagnosis of AS is often preferred.
NLD can also occur with other disorders. As with Asperger syndrome, NLD exists on a spectrum, and those affected can experience it in a range of ways. Those with an NLD diagnosis can experience some or all of the symptoms, and to varying degrees.
Non verbal learning disabilities affect one in ten learning disabled children.
