Wireless data transfer technology has significant potential to become a practical method to improve symptom monitoring and communication between patients and providers.
Verbal IQ deficits are frequently reported for school-age children with sickle cell disease (SCD), yet the profile of language abilities in SCD is unclear. We examined semantic, syntactic, and phonological processing in five-to-seven-year-olds at high neurologic risk based on SCD subtype (N = 33), at low neurologic risk with SCD (N = 21), and without SCD (N = 54). Low-risk SCD did not show language processing deficits. High-risk SCD showed deficits in all three language domains. Language processing deficits in SCD at the start of middle childhood are related to neurologic risks and include language skills beyond vocabulary.
White Americans generally exhibited more activation in regions associated with conflict resolution and cognitive control, while African Americans exhibited activation mostly in areas associated with emotion and memory. Our findings further imply that previous exposure to race-related incidents for African Americans may alter neural responses to White American targets in imaging studies. Implications of the findings are discussed.
Sickle cell disease (SCD) is blood disorder with a high risk for cerebral vascular morbidities that impact neurocognitive functioning. Specific cognitive abilities are known to be more sensitive to neurologic effects of SCD than IQ scores, yet there is little consensus about which measures to use to assess neurocognitive functioning. We evaluated the ability of the Executive Abilities: Methods and Instruments for Neurobehavioral Evaluation and Research (EXAMINER) Battery to detect neurologic effects in SCD. Thirty-two youth with SCD and sixty demographically-matched comparison youth completed the EXAMINER Battery and selected tests from the Woodcock-Johnson Tests of Cognitive Ability, 3rd edition (WJ-III). Neurologic severity was examined via clinical history for morbidities and midsagittal corpus callosum (CC) area. Results indicated cognitive performance decreased with increasing neurologic morbidity across all cognitive measures; two of four EXAMINER factors were related to CC area. The association with clinical history and midsagittal CC area appeared at least as large for the Examiner Battery scores as for the WJ-III measures. The Examiner Battery showed sensitivity to neurologic history and white matter effects in SCD; this new measure compares favorably to established measures of disease-related neurocognitive effects, but would benefit from further development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
