OBJECTIVE: Although extant research points to nonverbal learning disability (NVLD) as a distinct disorder, it is not included in the diagnostic nomenclatures, and there is heterogeneity in how it is defined. A working group was formed to gain consensus on a standard DSM-type definition for NVLD, a necessary first step for proposing its inclusion in future DSM editions, and the disorder was renamed to better reflect the core deficit-visual-spatial problems. METHOD: An iterative process was used to reach consensus on a DSM-style criteria set that reconceptualizes NVLD as developmental visual-spatial disorder (DVSD). This process, similar to that used during the DSM-5 revision, included working with an advisory group of NVLD experts and obtaining feedback from experts in youth psychiatric diagnosis and child and adolescent mental health practitioners. Data on stakeholder acceptance of the new name were collected from adults who self-identify as having NVLD and parents of youth with NVLD. RESULTS: During the iterative process, the criteria set shifted from syndromic, multi-area, and quantitative to single focused and more clinically oriented, conceptualizing youth with the disorder as having persistent deficits in a single area-processing or integrating visual and spatial information. This fills a gap in the DSM system, which includes diagnoses underpinned by problems in other cognitive domains. Data indicate stakeholder acceptance of the name. CONCLUSION: A standard definition for NVLD, reconceptualized as DVSD and included in DSM, will lead to improved identification of youth with clinically significant visual-spatial deficits and associated functional impairment and improve research in the area. DIVERSITY & INCLUSION STATEMENT: One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented sexual and/or gender groups in science.
