Lacunar strokes (small-vessel subcortical strokes) are commonly caused by "lipohyalinosis" or "microatheroma"(1). Both mechanisms appear to be related to hypertension and diabetes, but I haven't been able to find a good definition for these terms. What is the difference between these two mechanisms?
Unfortunately this paper titled "Mechanisms in lacunar infarction" doesn't define the terms either...
