This Week in Neurology: Stroke Risk, Gait, and RLS Therapies

From the New England Journal of Medicine, a trial analysis examined modified cerebral small-vessel disease scores in 1,454 hemorrhage-prone patients ^[1].

The authors describe how higher m-cSVD scores were associated with increased stroke risk in this specific group, though they note the evidence remains observational. Meanwhile, researchers in the Journal of neurology explored biomarkers by evaluating blood neurofilament light chain levels in 2,872 adult patients within 30 days of ischemic stroke onset or transient ischemic attack ^[2].

Findings suggest that higher blood NfL levels associate with worse 3-month outcomes for these patients.

Elsewhere this week, attention turned to movement disorders in the Journal of neurology, where a network meta-analysis of 1,118 patients investigated gait interventions ^[3].

The study indicates that visual and somatosensory cues most effectively boost walking speed and stride length in Parkinson's disease. A separate study in the Lancet (London, England) addressed acute intervention strategies for large-core ischaemic stroke within 24 hours ^[4].

This individual patient data meta-analysis compared endovascular thrombectomy versus medical management, with authors observing improved functional outcomes, while noting limited evidence for very large cores.

Finally, we also saw research in Frontiers in Medicine regarding symptom management for adults undergoing maintenance hemodialysis ^[5].

This systematic review and meta-analysis synthesized evidence on pharmacologic therapies for restless legs syndrome, finding significant improvements. The authors suggest considering gabapentinoids for RLS in this population, noting modest adverse event risks associated with dopaminergic agents.
