Stroke Localization Made Simple-

Stroke Localization Made Simple- MCA Stroke (Middle Cerebral Artery) ➊ Face & arm weakness > leg weakness ➋ Contralateral sensory loss ➌ Dominant side → Aphasia ➍ Non-dominant side → Neglect Remember: MCA = “M” for Mouth & aRM involvement ACA Stroke (Anterior Cerebral Artery) ➊ Leg weakness > arm weakness ➋ Personality changes ➌ Abulia (loss of motivation) ➍ Urinary incontinence Think: ACA affects the medial brain → lower limb area.⸻ PCA Stroke (Posterior Cerebral Artery) ➊ Contralateral homonymous hemianopia ➋ Visual symptoms ➌ Alexia without agraphia ➍ Macular sparing Classic clue: “I can write… but I can’t read”.⸻ Lateral Medullary Syndrome (PICA) ➊ Dysphagia & hoarseness ➋ Vertigo, nystagmus, ataxia ➌ Ipsilateral facial sensory loss ➍ Contralateral body pain/temperature loss ➎ Horner syndrome Crossed findings = brainstem lesion .⸻ Medial Medullary Syndrome (ASA) Remember the “3 M’s”: ➊ Medial lemniscus → ↓ vibration/proprioception ➋ Motor pathway → contralateral weakness ➌ Medulla CN XII → tongue deviation .⸻ Stroke localization becomes easy when you recognize the pattern!
