Understanding Parkinson's Disease

What is the primary chemical whose reduction leads to movement issues in Parkinson's disease?

• Acetylcholine

• Adrenaline

• Dopamine

• Serotonin

Which type of tremor is most commonly associated with Parkinson's disease?

• Action tremor

• Essential tremor

• Intention tremor

• Resting tremor

What is the term used to describe the jerky movements caused by muscle stiffness in Parkinson's disease?

• Flaccidity

• Spasticity

• Cogwheel rigidity

• Tonicity

How does bradykinesia affect movement in individuals with Parkinson's disease?

• It makes movements slower

• It causes involuntary shaking

• It results in muscle stiffness

• It leads to muscle weakness

What is the main difference between rigidity and bradykinesia in Parkinson's disease?

• Rigidity involves jerky movements, bradykinesia involves slow movements

• Rigidity causes tremors, bradykinesia causes stiffness

• Rigidity affects balance, bradykinesia affects speed

• Rigidity is a late symptom, bradykinesia is an early symptom

What is postural instability in the context of Parkinson's disease?

• Increased muscle tone

• Involuntary muscle contractions

• Loss of balance and stability

• Inability to initiate movement

Which symptom of Parkinson's disease is most likely to lead to falls?

• Tremors

• Rigidity

• Bradykinesia

• Postural instability

How does rigidity affect facial expressions in Parkinson's disease?

• It leads to excessive blinking

• It causes involuntary smiling

• It makes facial muscles stiff

• It results in drooping eyelids

What is the term for the sudden inability to move while walking in Parkinson's disease?

• Freezing

• Pausing

• Locking

• Halting

Which symptom of Parkinson's disease typically appears later in the disease progression?

• Postural instability

• Bradykinesia

• Rigidity

• Tremors
