Parkinson's disease is predominantly characterized by which of the following symptoms?

• A. Memory loss
• B. Rigidity and bradykinesia
• C. Hallucinations
• D. Severe headache

Answer: (B)

Parkinson's disease is predominantly characterized by rigidity and bradykinesia, which are hallmark features of this neurodegenerative disorder. Rigidity refers to the increased muscle tone and resistance to passive movement that can occur throughout the body, leading to stiffness. Bradykinesia is characterized by a gradual reduction in the speed and fluidity of movement, resulting in slowness and difficulty initiating movement. Together, these symptoms significantly impact a person's ability to perform everyday tasks. While other symptoms can occur in Parkinson's disease, such as memory loss or hallucinations, they are not the primary features of the condition. In the case of severe headaches, this symptom does not typically correlate with Parkinson's disease and is not a recognized characteristic of its pathology. Overall, the combination of rigidity and bradykinesia is central to the diagnosis and management of Parkinson's disease.
