World Stroke Organization #MondayTips
Every Monday, WSA Social Media Leader Rodrigo Guerrero publishes a #MondayTip on the WSA WorldStrokeEd Twitter account, covering a specific stroke related topic. You can find a compilation of our #MondayTips here!
#MondayTip
Hypoperfusion Intensity Ratio
#HIR may be the most practical collateral biomarker in AIS
⬆️High HIR (>0.4) → rapid core growth, ↑ hemorrhage risk, worse mRS.
⬇️Low HIR → robust collaterals & better EVT outcomes.

Cancer-related stroke ≠ routine ESUS
~50% of strokes in active cancer are cryptogenic, but many are cancer-driven hypercoagulable events
🔁14–29% recur at 1 year
⚖️Anticoag vs aspirin? Still equipoise
🧠Classify. Risk-stratify. Individualize

#FLAIR hyperintense vessels ≠ clot
🧩Hemodynamic clue!
🧠Distal FVH→collateral flow
⏱ Early window→possible viable penumbra
⚠️In TIA→ think persistent large-vessel stenosis
☝️Sometimes FLAIR tells you what perfusion can’t
🔎Look closely

#ISC2026
🌎ISC delivered fewer “home runs” and more hard truths: what works, what doesn’t, and where selection matters most in stroke care
From extended-window thrombolysis to FXIa inhibition, #ISC26 highlights where stroke care is truly moving — and where it isn’t.

#Prehospital beyond MSU
🚑🧠 Most strokes aren’t seen by MSUs.
The future? Smart regular ambulances using telemedicine, AI, portable brain devices & ultra-early blood biomarkers to triage stroke faster—anywhere

🧠 New @American_Stroke #Stroke Guidelines
✔️ TNK = first-line option for IVT
✔️ EVT expanded (large cores & basilar ≤24h)
❌ No aggressive BP or glucose lowering
👶 First pediatric AIS guidance
⏱️ Systems of care matter more than ever

#MondayTip
🧠 Stroke #recovery doesn’t end at discharge
⏱️ Evidence shows rehab is often too little, too short, and too late, despite clear guidelines
👥 Early intensity, MDT teamwork, and 📅 long-term follow-up are key to better outcomes

Young Stroke: an update
☝️Stroke isn’t just an older-person disease
📈Ischemic stroke in 18–49y is⬆️,often driven by non-traditional risks
🔤Think ABC diagnostics
🎯Tailor 2ry prevention
🛑Don’t ignore long-term cognitive & psychosocial burden🧠
