← Human Body & HealthIf a closed-head injury causes widespread axonal shearing, which consequence is most likely due to this diffuse injury?
A)Localized motor cortex paralysis develops
B)Unilateral pupillary dilation rapidly occurs
C)Widespread cognitive deficits progressively emerge✓
D)Immediate cerebrospinal fluid pressure decreases
💡 Explanation
Diffuse axonal injury (DAI) involves widespread damage across the brain's white matter tracts, because this shearing disrupts neuronal communication networks throughout the cerebrum, therefore causing progressive cognitive impairments, rather than focal motor deficits or immediate pressure changes.
