Which of the following describes Parkinson's disease?

• A. A disorder affecting the peripheral nervous system
• B. A disorder that degenerates the central nervous system
• C. A temporary condition that resolves with age
• D. A condition solely caused by genetic factors

Answer: (B)

Parkinson's disease is primarily characterized as a neurodegenerative disorder that affects the central nervous system. It primarily involves the destruction of dopamine-producing neurons in the brain, particularly in an area called the substantia nigra. This degeneration leads to the hallmark symptoms of Parkinson's, which include tremors, rigidity, bradykinesia (slowness of movement), and postural instability. Understanding the nature of Parkinson's as a central nervous system disorder is crucial for recognizing its impacts on motor control and various cognitive functions. This condition typically progresses over time and can significantly affect a person's daily life, distinguishing it from other disorders that might only affect the peripheral nervous system or resolve over time.
