Midbrain
What is Dyskinesia and how does it typically present in Parkinson’s
Involuntary and abnormal movements - tremors/shaking
What is Bradykinesia?
Slowed movements
What is Hypophonia?

What is Bradylalia?
Slow speech rate
What is Festination?
Increased movement speed but reduced range of motion
What is dysarthria?
