The study did not measure whether NAC improves thinking skills or memory in stroke patients, as it only measured stroke severity symptoms.

Stroke patients who receive NAC along with standard treatment show better recovery from stroke symptoms over time compared to those who only get standard treatment.

Taking NAC along with regular stroke treatment lowers a measure of harmful oxidative stress in the blood of stroke patients.

When comparing stroke patients who received NAC to those who didn't, only one blood marker related to oxidative stress showed a significant difference between the groups.

For most stroke patients, NAC treatment didn't significantly change most blood markers related to oxidative stress compared to standard treatment alone.
