Hypoglycemia, or low blood sugar, significantly impacts neurological function primarily due to the brain's dependence on glucose as its main energy source. When glucose levels drop, the brain is deprived of the necessary fuel it needs to operate effectively. This deficiency can lead to a range of cognitive and neurological disturbances.

Seizures can occur as the brain's electrical activity becomes disrupted, and confusion may arise due to impaired cognitive functions and diminished ability to process information. These symptoms demonstrate the brain's sensitivity to fluctuations in glucose levels and underscore how critically glucose levels need to be maintained for proper neurological health.

In contrast, other options do not accurately reflect the impact of hypoglycemia. While hypertension isn't a direct consequence of low blood sugar, memory enhancement is not associated with hypoglycemia; rather, low glucose levels typically impair memory function. Similarly, while hypoglycemia can affect reflexes, the primary and immediate threats to neurological function are the confusion and potential for seizure activity. Thus, low blood sugar significantly alters brain function, leading to seizures and confusion.
