We asked José Suarez - Past President, NCS; Founding Chair, NCRN - why he's coming to #ISAH2026.

"The latest treatments, what the future holds — and of course, beautiful Sydney."

We'll take it!

Thrombectomy works.
Most of the world can't access it.

Throwback to 2013 - a Pecha Kucha on aSAH complications: non-convulsive seizures, neurogenic cardiomyopathy, CSW vs SIADH, rebleeding, hydrocephalus. Old video, still holds up. These debates belong at #ISAH2026 (https://t.co/DgFaBgZCh0). 🎬 https://t.co/8GEKd3sUXp

Almost a year ago I interviewed an AI (Simon, GPT-4o) about vasospasm & DCI in aSAH. AI has moved fast - but Simon was on it. Worth a revisit. These debates are what #ISAH2026 is for. 🎙️ https://t.co/Aj2sTHawuT https://t.co/DgFaBgZCh0

[ISAH @IntSAH]

Write the guideline.
Find the gaps.
Design the trial.

✅ GOOD — Nimodipine is still thought to work.
❌ BAD — HHH therapy. RIP. Euvolaemia won.
💀 UGLY — "Vasospasm" ≠ "DCI". Please stop.
ISAH 2026 PK comp coming soon. 20 slides. 20 seconds.

[ISAH @IntSAH]

Were we measuring the wrong things in DCI trials? Or is the biology more complicated than we thought? Probably both.

Jose Suarez (Johns Hopkins) on what needs to change before the next trial.

We understand DCI better than ever.
We still can't reliably treat it.
That gap is exactly what #ISAH2026 is for.

PK #2: ICU management of aSAH.
Fever, transfusion thresholds, glycaemic control, VTE, fluids — the daily grind. What's moved: albumin, CVP, glucose targets, Hb targets
ISAH 2026 runs its own PK comp. Best entries present in Sydney.

"Practice-changing things that maybe aren't guideline ready — but get us ready for the next version."

That's @NerissaKoMD on why ISAH matters. We'll take it.

Sydney. November. https://t.co/i0MNzWFZQQ

[ISAH @IntSAH]

This aSAH PechaKucha is 12+ years old. The emergency framework holds. The 2012 guidelines don't. TXA and coiling-vs-clipping have both moved on.
Sharing it as a warm-up — ISAH 2026 is running a PK competition. Best entries present in Sydney.

Jose Suarez on what he would NOT do in a DCI trial: choose one medication with one mechanism of action. "We'll just be replicating the same failures."

It's a short answer. The implications aren't.

SAH guidelines have an RCT purity problem.

Nerissa Ko (UCSF): for rare, variable diseases, holding out for trials that may never come isn't rigour - it's stasis.
