All the following myopathies are characterized by proximal muscle wasting EXCEPT
Correct Answer: D
Rationale: Central core myopathy typically presents with mild weakness and hypotonia rather than significant proximal muscle wasting, unlike the muscular dystrophies listed.
Question 2 of 5
In Guillain-Barré syndrome, the onset is gradual and progresses over days or weeks. The maximal severity of weakness is usually reached by
Correct Answer: B
Rationale: In GBS, maximal weakness typically peaks by 4 weeks, per diagnostic criteria, though it varies.
