Which potential neurological effect can occur due to nitrous oxide?

Cognitive impairment is a potential neurological effect that can occur due to nitrous oxide use. This can manifest as difficulties with attention, memory, and the ability to perform complex tasks. Nitrous oxide affects the central nervous system, leading to reversible changes in mental functioning during and sometimes after exposure to the gas.

The effects can vary depending on the duration and concentration of exposure, as well as individual susceptibility. Particularly with prolonged or excessive use, there may be a greater risk of cognitive deficits that can become more pronounced over time.

While the other options suggest various enhancements or improvements—which are not associated with nitrous oxide—cognitive impairment highlights the risks involved in its application, especially in clinical or recreational scenarios where adequate caution isn't exercised.
