NCOG-37. THE UTILITY OF NEUROPSYCHOLOGICAL SCREENING IN MULTIDISCIPLINARY CLINICS FOR PEDIATRIC NEURO-ONCOLOGY POPULATIONS

BACKGROUND The purpose of this project was to examine the utility of neuropsychological screening in multidisciplinary clinics for pediatric neuro-oncology populations and determine whether a brief evaluation can adequately screen children for cognitive dysfunction or psychiatric comorbidities. METHODS Children underwent neuropsychological screening as part of their multidisciplinary clinic visit. This screening evaluation consisted of clinical interview, neuropsychological testing, and the completion of emotional/behavioral checklists. Our neuropsychological test battery included the Kaufman Brief Intelligence Test-Second Edition (KBIT-2) and the NIH Toolbox Fluid Cognition Composite (consisting of 6 subtests). RESULTS Over a six-month period 40 children and adolescents with CNS tumors and/or NF1 were seen in our neuropsychology screening clinic. Females made up 37.5% of the sample. The average age was 11.1 years (range=5-25 years). The average time to complete neuropsychological testing was 56.8 minutes. On average, children in this sample met criteria for 1.8 neuropsychological diagnoses with an average of 1.2 new diagnoses that had not been given prior to their neuropsychological screening. The most common new diagnoses were major or mild neurocognitive disorder (mild=27.5%, major=20%), anxiety (27.5%), ADHD (15%), mood disorder (12.5%), and intellectual disability (10%). On average, these children performed lower than expectation on neurocognitive tests, including intellectual functioning (KBIT-2 Verbal IQ=93.1; KBIT-2 Nonverbal IQ=88.7; KBIT-2 Total IQ=90.1), attention (NIH Flanker T-Score=44.1), working memory (NIH Working Memory T-Score=42.9), processing speed (NIH Processing Speed T-Score=39.9), cognitive flexibility (NIH Card Sort T-Score=43.4), memory (NIH Picture Memory T-Score=44.5), and fluid cognition (NIH Fluid Cognition Composite T-Score=38.7). Behavioral health recommendations were needed for 72.5% of this sample. Educational recommendations were needed for 62.5%. CONCLUSIONS Brief neuropsychological screening completed as part of multidisciplinary clinics for pediatric neuro-oncology patients was efficient and useful in identifying neuropsychological diagnoses in children.
