← Human Body & HealthWhich failure increases risk of osmotic demyelination following rapid hyponatremia correction?
A)Increased aquaporin channel expression✓
B)Decreased blood-brain barrier porosity
C)Reduced cerebral blood flow
D)Enhanced neuronal glucose metabolism
💡 Explanation
Increased aquaporin channel expression accelerates water influx into brain cells during correction of hyponatremia with osmosis; therefore, astrocytes swell excessively, leading to demyelination because of cellular damage, rather than protection from ionic changes.
