🩸🧠What’s new in Cerebral Amyloid Angiopathy?

🚀Updates from the 8th International CAA Conference
#iCAAPerth2022 🌏🇦🇺
..and my take (denoted by:🧔🏻)

*Focus of 🧵 will be on clinical/translational aspects*

#AmyloidAngiopathy #neurotwitter #stroke #Neurology #dementia #NeuroRad 🔥🧠CAA-ri (CAA-related inflammation)

@Ellis_van_Etten provided a clinical update on CAA-ri
-Key need for improving diagnostic tools and clarifying best 🧯treatment options

🧔🏻: Subclinical, non-fulminant CAA-ri forms are beginning to be appreciated!

The🟡 Spot Sign might be dead🧟🧟‍♂️ for ICH🧠🩸!

(At least as practice-changing marker for Intracerebral Hemorrhage expansion)

🍄ICH shape/density markers on plain NCCT are more promising👇🏿👇🏿

These markers still need harmonization and improvement of diagnostic accuracy..

re: ICH Prevention in People w ⬆️Risk MRI findings in @American_Heart updated 2022 ICH guidelines🧠🩸

📌 Refers to incidentally found MRI markers of small vessel disease (SVD) - a common question

Prompted by @interneurona unpacking below (short 🪀) For context:
🚫MRI is not routinely done for risk stratification of first-ever spontaneous ICH risk

🔮MRI is occasionally available in certain people/pts w/o ICH: may show SVD markers concerning for future ICH risk

〽️These markers are: microbleeds, superficial siderosis

 PRES 🗜️
⚡️huge spectrum
⚡️high index of suspicion in ptns with risk factors (often with HTN urgency, immunosuppression, sepsis) + seizures
🕵🏻‍♂️may not be posterior, may not be reversible, may not present as a syndrome!!
