Longitudinal Analysis of Sleep‐Disordered Breathing and Cognitive Outcomes in Children Living With Sickle Cell Anaemia

open access: yesClinical Otolaryngology, EarlyView.
ABSTRACT Objectives Sleep‐disordered breathing (SDB) and cognitive challenges are commonly observed in children living with sickle cell anaemia (SCA). This study investigated the longitudinal change in polysomnographic outcomes and the association with cognitive functions in children living with SCA.

Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

Academic and cerebrovascular outcomes after neurodevelopmental screening in sickle cell disease: A longitudinal cohort study

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Neurodevelopmental screening in toddlers or preschoolers with sickle cell disease (SCD) predicts future academic deficits. Screening sensitivity for future academic deficits is highest in preschoolers with SCD. Brief neurodevelopmental screening tools can identify high risk children for early intervention. Abstract Aim To assess the predictive validity

All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

open access: yesScandinavian Journal of Psychology, EarlyView.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...
