Nonverbal Learning Disorer (NLD) (also known as NVLD) is a developmental or learning disorder with manifestations in the following domains: a) somatosensory and motor functions; b) visuospatial and visuoconstructive functions; c) arithmetic; d) social cognition, and e) inferential reasoning. Psychopathologically, externalizing symptoms predominate in the preschool and early school years, often confounding with attention-deficit/hyperactivity and oppositional-defiant disorders. Towards the preadolescent and adolescent years there occurs a gradual shift towards internalizing symptoms related to anxiety and depression. Internalizing symptoms may be best thought of as a consequence of long-term academic and social-interpersonal failure: a reactive disorder. In many people with NLD, social isolation and awkwardness are consequences of long-term social-interpersonal failure. Disorders in the social domain may be best conceptualized as lack of social cognition and, consequently, social abilities. Individuals with NLD have difficulties generalizing from one situation to another and learning from experience. It can be hard for them to interpret the subtleties encountered in social interactions, which may involve, for example, nonverbal gestures and facial cues indicating irony or cynicism.
