Trade-offs in quality-of-life assessment between the modified Rankin Scale and Neuro-QoL measures.
The objective of this study was to describe the physical and cognitive health of patients with differing levels of post-stroke disability as defined by modified Rankin Scale (mRS) scores. Cross-sectional correlations were also compared between the mRS and the Quality of Life in Neurological Disorders (Neuro-QoL) T-scores to longitudinal correlations of change estimates for each measure. A total of 745 patients with ischemic stroke (79%) or transient ischemic attack (21%) were enrolled in this study. There were larger differences observed in cognitive function for the severe mRS groups. Larger differences in physical function were observed in the mild-moderate mRS groups. These findings undermine the validity and utility as an outcome measure in longitudinal studies in ischemic stroke patients. But it is still efficient at capturing important differences in patient-reported quality of life, and is useful for identifying meaning cross-sectional differences among clinical subgroups.

Elevated cerebrospinal fluid protein is associated with unfavorable functional outcome in spontaneous subarachnoid hemorrhage.
Subarachnoid hemorrhage (SAH) is a devastating neurologic event for which markers to assess poor outcome are needed. Elevated cerebrospinal fluid (CSF) protein may result from inflammation and blood-brain barrier (BBB) disruption that occurs during SAH. In this study, the investigators sought to determine if CSF protein level is associated with functional outcome after SAH.

Time to neurological deterioration in ischemic stroke.
This study examined the time to neurological deterioration (ND) in ischemic stroke. The study concluded that despite having similar stroke severity and age, patients with nonreversible causes of ND had significantly shorter median time to ND when compared to patients with reversible causes of ND.
