🧠 Stroke Localization Made Simple

⸻

1️⃣ 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

⸻

2️⃣ 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

⸻

3️⃣ 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”

⸻

4️⃣ 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

⸻

5️⃣ 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!
