Neurological System Questions Questions
Question 1 of 5
In initial stage of Parkinson disease the most typical involuntary movement is the following:
Correct Answer: C
Rationale: Tremor is the correct answer because it is one of the earliest and most characteristic symptoms of Parkinson's disease. The tremor is typically a resting tremor, which decreases with voluntary movement and is often described as ‘pill-rolling' due to its appearance. It results from the degeneration of dopaminergic neurons in the substantia nigra.

Question 5 of 5
A previously healthy 26-year-old male is brought to the emergency department due to muscle weakness. He reports mild weakness in his legs that has progressively worsened over a few days to the point that he can barely move his legs. He has some numbness in his legs and his arms feel weak. He has recently recovered from a respiratory infection. 1/5 muscle strength is noted throughout the lower extremities, as well as absent patellar and ankle reflexes. 3 to 4-/5 muscle strength is appreciated throughout his upper extremities. A lumbar puncture is performed, which shows the following: Cell count: 4 cells/mm3, Glucose: 67 mg/dL, Protein: 187 mg/dL Gram stain: no organisms Spirometry is performed, which shows a forced vital capacity of 0.85 L. Which of the following is the best next step in management?
Correct Answer: B
Rationale: The patient's presentation of rapidly progressive weakness, areflexia, and elevated cerebrospinal fluid protein with normal cell count (albuminocytologic dissociation) is classic for Guillain-Barre syndrome (GBS). The forced vital capacity of 0.85 L indicates respiratory failure, necessitating immediate intubation to protect the airway and provide mechanical ventilation. Intravenous immunoglobulin and plasma exchange are treatments for GBS but are secondary to securing the airway in this critically ill patient.
