NON-VERBAL LEARNING DISABILITIES

Research in the area of NLD reports diagnostic criteria, assessment methods and treatment strategies derived from case studies and clinical experiments involving small number of participants and controls. The American Psychiatric Association reported that approximately 1% of school-age children have a mathematics disability (APA, 2003). Wicks-Nelson and Israel (2003) suggested that there is “scant information about prevalence and outcome for mathematics disorder” (p. 277). The prevalence of NLD has not been reported in research literature.
