No Effect Of Randomizing Concussion Symptom Presentation On Symptom Number Or Severity Reporting

Acute concussion symptom severity and delayed symptom resolution.

BACKGROUND AND OBJECTIVES Up to 30% of children who have concussion initially evaluated in the emergency department (ED) display delayed symptom resolution (DSR). Greater initial symptom severity may be an easily quantifiable predictor of DSR. We hypothesized that greater symptom severity immediately after injury increases the risk for DSR. METHODS We conducted a prospective longitudinal coho...

Effect of asthma severity on symptom perception in childhood asthma.

Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS) and peak expiratory flow (PEF) rates in as...

Connectomic markers of symptom severity in sport-related concussion: Whole-brain analysis of resting-state fMRI

Concussion is associated with significant adverse effects within the first week post-injury, including physical complaints and altered cognition, sleep and mood. It is currently unknown whether these subjective disturbances have reliable functional brain correlates. Resting-state functional magnetic resonance imaging (rs-fMRI) has been used to measure functional connectivity of individuals afte...
