Which of the following are common symptoms of Parkinson's disease?

1. Dizziness, rapid weight loss, blurred vision

2. Bradykinesia, trembling, impaired balance, stiffness

3. Numbness in the extremities, rapid heart rate, insomnia

4. Increased appetite, anxiety, hallucinations

The correct answer is: Bradykinesia, trembling, impaired balance, stiffness

Bradykinesia, trembling, impaired balance, and stiffness are hallmark symptoms of Parkinson's disease, a progressive neurological disorder that affects movement. Bradykinesia refers to the slowness of movement, making everyday tasks more challenging for individuals. Trembling, often seen in the hands or limbs, is also a classic sign. Impaired balance can lead to an increased risk of falls, while stiffness or rigidity in the muscles contributes to the characteristic difficulties with movement and postural control. These symptoms arise from the degeneration of dopamine-producing neurons in the brain, which is a key feature of Parkinson's disease. The other options list symptoms that are not typically associated with Parkinson's disease. While dizziness and rapid weight loss may occur in various medical conditions, they do not specifically indicate Parkinson's. Numbness in the extremities and rapid heart rate are more aligned with other neurological or cardiovascular issues. Increased appetite, anxiety, and hallucinations can involve different psychological or psychiatric conditions, rather than being primary symptoms of Parkinson's disease.
