[Non-verbal learning disorder: cognitive-behavioural characteristics and neuropsychological aspects].
BACKGROUND
Non verbal learning disorder is a neurological condition which is considered to be a developmental disability. It is characterised by a specific dysfunction in motor, visuospatial and social skills in patients with a normal intellect and development of language. Warning signs in school are poor psychomotor coordination, arithmetic skills and drawing activities. Social judgment and social problem solving are also typically impaired. Furthermore, these patients seem to have increasing risk of emotional disorders.


CONCLUSIONS
Current evidence and theories suggest that dysfunction of white matter in the right hemisphere could be the cause. The clinical characteristics and the diagnostic criteria have not fully agreed on. A comprehensive neuropsychological evaluation reveals specific and heterogeneous patterns of difficulties for each child that would make possible to address and accommodate an educational program.
