The Impacts of Obstructive Sleep Apnea Severity on Brain White Matter Integrity and Cognitive Functions in Children: A Diffusion Tensor Imaging Study

Decreased baseline SpO₂, WM impairment, and intelligence decline were all observed only for SG, but not for MG, implying an associated relationship among decreased SpO₂, WM impairment and WM impairment. Thus, for SG, additional assessments of brain damage and cognitive function decline are needed for prognostic evaluation of OSA.
