Can smaller lacunes derived from recent small subcortical infarcts play a role in cognition at one- year after mild stroke?

Recent small subcortical infarcts (RSSI) may evolve into lacunes (cavities) smaller than 3mm or even disappear. The 3mm size cut-off used in guidelines might underestimate SVD burden. We hypothesised that participants with smaller (<3mm) lacunes have better cognitive outcomes at one-year follow-up than those with larger lacunes. We also aimed to determine rates of development of lacunes <3mm.
