About
The Vascular Brain is a clinical education project by Zaka Ahmed, MD — a vascular neurologist with fellowship training at the University at Buffalo. A working notebook of trials, protocols, and bedside reasoning, kept honest by the consults that come in overnight.
Vascular Neurologist
I am a vascular neurologist with ACGME-accredited fellowship training at the University at Buffalo across the full stroke continuum — prehospital triage, code stroke leadership, advanced neuroimaging, EVT coordination, and the long arc of secondary prevention.
Before fellowship, I trained in neurology at Howard University Hospital in Washington, DC — serving as Chief Resident in 2024–2025. My research training has been split between the Hillis lab at Johns Hopkins, studying how language and motor functions recover differentially with reperfusion in large-vessel-occlusion stroke, and the neurocritical care group under Neeraj Badjatia at the University of Maryland, coordinating trials in ICH, SAH, and ECMO outcomes.
This site is the long-form counterpart to that work — a place to write carefully about what the literature says and what it doesn't, in a voice that respects both the data and the clinicians who carry the weight of acting on it.

§ 06 · The mission
Stroke medicine is one of the most evidence-rich, time-critical fields in neurology — and one of the easiest places for a gap to open between what the literature says and what happens in the next hospital corridor. The Vascular Brain is an attempt to keep that gap narrow.
Each piece is written to be used: by the resident answering a stroke alert, by the fellow preparing for boards, by the nurse practitioner managing a long-term clinic, by a patient's family member trying to understand what just happened to someone they love. The voice is the same in all of them — careful, honest about uncertainty, and not afraid of detail.
The goal isn't to summarize trials. It is to translate them — into protocols, into decisions, into language a tired team can still act on at 3 a.m.
If you read something here that helps, or that you disagree with, write back. The notebook is better with company.
