Which is NOT a sign of severe brain damage?

Normal coordination is the correct answer because it is not typically associated with severe brain damage. In cases of severe brain injury, patients often exhibit signs of dysfunction in motor control and neurological status. This can manifest as abnormal body posturing, decreased consciousness, or fixed and dilated pupils, all of which suggest significant impairment in neurological function.

Abnormal body posturing indicates that the brain may not be processing signals correctly, often observed in cases of severe hemispheric damage or brainstem dysfunction. Decreased consciousness is a direct indicator of brain injury, reflecting a reduced ability to respond to stimuli or an altered level of awareness. Fixed and dilated pupils are particularly alarming signs that may suggest increased intracranial pressure or severe disruption in brain function, indicating potential brain stem involvement. Each of these symptoms reflects critical neurological deficits that arise from severe brain damage, contrasting sharply with the presence of normal coordination, which suggests intact neurological function.
