Cognitive outcomes of childhood primary CNS vasculitis.

Objective: To characterize the clinical cognitive phenotypes and severity of cognitive burden according to disease subtype in children with primary central nervous system vasculitis (cPACNS). Method: This retrospective multicenter inflammatory brain disease database study examined the neuropsychological outcomes of 80 children (44 male; mean age = 7.89 years, SD = 4.17) consecutively diagnosed with primary CNS vasculitis between 1992 and 2016. Twenty-one children had small-vessel disease (AN_cPACNS), and 59 had large-vessel disease (including 49 nonprogressive [APNP_cPACNS] and 10 progressive [APP_cPACNS]). Neuroimaging revealed MRI abnormalities in 100% and 90% of children with large- and small-vessel vasculitis, respectively. The primary outcomes were Full Scale IQ (FSIQ) and the index scores from the Wechsler Intelligence Scale for Childrenāˆ’III (WISC-III, WISC-IV, and WISC-V). Analyses explored the effect of disease subtype. Results: Intellectual functioning was assessed on average 2.82 years after symptom onset. Children with small-vessel CNS vasculitis had significantly lower FSIQ scores than did those with large-vessel CNS vasculitis (Ms = 81.90 vs. 94.82; p = .04). Intellectual disability (FSIQ
