Real-Life Examples of Motor Cortex Damage

📚 Quick Study Guide

• 🧠 The motor cortex, located in the frontal lobe, controls voluntary movements.
• ⚡ Damage can result from stroke, traumatic brain injury, tumors, or neurodegenerative diseases.
• 🚶 Common symptoms include paralysis (hemiplegia), weakness (paresis), spasticity, and difficulties with coordination (ataxia).
• 🗣️ Damage can also lead to speech difficulties (dysarthria) if the areas controlling speech muscles are affected.
• rehabilitation often involves physical therapy, occupational therapy, and speech therapy to regain function.
