#Genetic & #SVD
🧬🧠
✅1,5% of cerebral #SVD are #monogenic disorders
✅AR, AD or X-linked
☝🏼Absence of family history doesn't rule out diagnosis because of
👉de novo mutation
👉reduced expression or
👉incomplete penetrance
✅ahajournals.org/doi/10.1161/ST…

#CMB
🔬#Pathology: recent or old microhaemorrhages
🩸Microvessel injuries, ie: dilatation/fragmentation of the wall, amyloid-ß (in CAA) and fibrin extravasation
🩸Extravasation of red blood cells
🩸#hemosiderin-laden macrophages

In daily practice #CMB represents a radiological marker of #small vessel disease
In general:
🩸Strictly #lobar CMBs👉CAA
🩸Strictly #deep👉hypertension-related SVD ie #arteriolosclerosis
🩸Mixed 👉combination👆, but must think #hereditary #SVD, ie #CADASIL
