🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
Journal of the American College of Radiology : JACR (2026) - Practice Guideline
Key Findings
- The updated imaging guidance reports 94% diagnostic accuracy at 3T MRI when the 2024 McDonald criteria are integrated with advanced MRI features.
- Central vein sign, paramagnetic rim lesions, and gadolinium-enhancement patterns improve distinction between active inflammatory lesions, chronic plaques, and alternative demyelinating disorders.
📋 Practice Implication: When evaluating suspected or established MS, clinicians should coordinate MRI protocols with radiology so lesion morphology, activity, and key differential-diagnosis features are captured consistently.

PeerJ (2026) - Network Meta-Analysis
Key Findings
- Across 35 studies involving 2,804 participants, occupational-therapy sleep interventions ranked highest for subjective sleep quality (SUCRA 94.2%), followed by mindfulness (85.9%) and sleep-hygiene education (78.6%).
- Effleurage massage ranked highest for reducing insomnia severity (SUCRA 91.9%), with cognitive-behavioral therapy next (80.1%).
📋 Practice Implication: Sleep care in MS can be tailored toward occupational-therapy-based programs or CBT-oriented approaches, with the choice guided by whether the dominant problem is poor sleep quality or insomnia severity.

Multiple sclerosis and related disorders (2026) - Systematic Review
Key Findings
- In 28 studies comprising 11,213 patients, pooled diagnostic performance for MS disease activity was modest, with AUC values of 0.61-0.71 (61%-71%).
- A 10 pg/mL cutoff for clinical relapse produced sensitivity of 0.69, specificity of 0.65, and AUC of 0.72; 50% of studies were judged at high risk of bias.
📋 Practice Implication: sNfL should not be used as a standalone trigger for treatment decisions; interpret it alongside symptoms, examination, MRI findings, assay context, and longitudinal trends.

European journal of neurology (2026) - Systematic Review
Key Findings
- Among 72 studies and 9,915 adults with CIS, younger age and multifocal presentation were associated with subsequent MS diagnosis (odds ratios 1.60 and 1.55, respectively).
- Higher T2 lesion burden and periventricular, corpus callosum, infratentorial, spinal-cord, and gadolinium-enhancing lesions, plus CSF oligoclonal bands, were also associated with conversion (odds ratios 1.40-14.89).
📋 Practice Implication: Risk assessment after CIS should integrate clinical presentation, lesion distribution and burden, and CSF inflammatory markers to identify patients needing closer surveillance and individualized early-treatment discussions.

Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology (2026) - Systematic Review
Key Findings
- Across 13 studies involving 4,016 individuals, each unit increase in NfL was associated with a 4% increase in adverse-event risk; levels above a threshold were associated with 2.61-fold higher risk.
- NfL had stronger predictive performance in relapsing-remitting MS than in mixed disease (RR 3.82 vs 1.03) and was associated with neurodegenerative EDSS worsening, whereas GFAP showed no significant overall prognostic value.
📋 Practice Implication: NfL may support subtype-aware prognosis and monitoring for silent neurodegenerative progression, but GFAP should not currently be treated as an independent prognostic marker.

Summary
The selected high-significance studies emphasize updated MRI criteria, modifiable symptom management, and risk stratification after clinically isolated syndrome. Biomarker evidence is complementary rather than interchangeable: serum neurofilament light chain shows subtype- and activity-dependent prognostic value, while its standalone diagnostic accuracy remains limited.
