Lenticulostriate (deep perforator) strokes — classic lacunar patterns and MRI detection (Advanced)

Advanced course: small perforator artery strokes (lenticulostriate) can cause pure motor or sensorimotor deficits without cortical signs. Learn what it looks like, how CT/MRI detect it, and why prevention targets matter

What you'll learn

  • Understand deep perforator (lenticulostriate) strokes as small but impactful
  • Recognize lacunar patterns (pure motor, dysarthria-clumsy hand) in plain language
  • Understand why CT may be normal early and MRI DWI detects small infarcts
  • Know questions about risk factors (BP/diabetes) and secondary prevention
