The 2025 @WorldStrokeOrg scientific statement on cerebral amyloid angiopathy (CAA) - a "very prevalent" small vessel disease - is discussed by @a_charidimou at #WSC2025, including stratification of future bleeding risk in probable CAA cases and the role of inflammation

🫀 AFib + prior brain bleed 🧠 or CAA? 🚨New meta-analysis (14 studies, 1,235 pts) finds LAAO may be safe: ✅ Stroke ~2% ✅ Recurrent bleed ~2% ✅ Major bleed ~3% ⚠️ Evidence low — RCTs needed! #StrokePrevention #AFib #LAAO @a_charidimou journals.sagepub.com/doi/abs/10.117…

Excited to present our newly published study/meta-analysis on LAAO in patients with previous ICrH and/or CAA. Many thanks to my mentor @a_charidimou. Without his guidance this endeavor would not be possible. I also want to thank Dr Archontakis-Barakakis and Dr Chlorogiannis...

10/ 🔹 GRE / SWI (Gradient Echo / Susceptibility Weighted Imaging) These sequences detect magnetic distortion from paramagnetic substances—like iron, calcium, or blood. 🩸 Blood breakdown = iron = black on imaging 🧠 Use for: – Microbleeds – Hemorrhagic conversion – Cavernomas – Calcifications Know your anatomy: iron is naturally present in regions like the globus pallidus. 🧠 The image below shows microhemorrhages in the thalamus and basal ganglia. Those small, scattered, circular dark lesions are microbleeds. The iron deposits distort the local magnetic field, leading to a signal dropout on SWI.

@a_charidimou kicks off #ESOC2025 @ESOstroke with a fine talk on application of diagnostic criteria in CAA

⭕️🧠 CAA progression & neuropath staging (CAA=Cerebral Amyloid Angiopathy) Here is my take👇 which will try to unpack 🧵 in the coming days. ⛱️ CAA is not a single disease and is not uniform 🌂CAA does NOT invariably progress to bleeding as part of it's natural history, but rather there are hemorrhagic/advanced and non-hemorrhagic phenotypes which progress and behave distinctly 🧊 We only see the tip of the CAA iceberg #NeuroTwitter #NeuroRad #Neurology #Neurosurgery #stroke #MedStudentTwitter #FOAMncc #MedTwitter #amyloidangiopathy #FOAMncc #neuroscience #brain #Alzheimers #Alzheimer #illustration #neuropath #cSVD x.com/a_charidimou/s…

Here is a pearl tutorial on CAA from the master himself. Plenty of CME credits here. Go challenge yourself. See if you have understood the Boston criteria adequately. x.com/a_charidimou/s…
