What is a common effect of cerebral edema?

Cerebral edema is the accumulation of excess fluid in the brain's interstitial space, leading to swelling. One of the main concerns when cerebral edema occurs is the potential for increased intracranial pressure (ICP). As the brain swells, the volume within the rigid confines of the skull increases, which can disrupt normal blood flow and brain function. Increased ICP can lead to serious complications, including herniation of brain tissue and severe neurological deficits.

The other options do not typically correlate with cerebral edema. Increased sensitivity to sound is not a direct result of cerebral edema, while loss of taste and skin rashes are more related to other conditions or neurological issues but are not direct effects of edema in the brain. Thus, the correct answer focuses on the significant and potentially life-threatening consequence of increased intracranial pressure resulting from cerebral edema.
