Utility of Caregiver Signaling Questions to Detect Neurocognitive Impairment in Children with Sickle Cell Disease.

The American Society of Hematology cerebrovascular guidelines for sickle cell disease (SCD) recommend surveillance using signaling questions to screen for neurocognitive difficulties, though the clinical utility of these signaling questions has yet to be established. This study aimed to determine the clinical utility of caregiver signaling questions for detecting significant neurocognitive impairment (defined as >1.5 standard deviation (SD) below the normative mean on 2 or more measures) and domain-specific impairment (defined as >1.
