- Smoking cessation is associated with a lower dementia risk and slower cognitive decline, comparable to never smokers.
- Benefits are largely limited to individuals with no or modest postcessation weight gain (≤5 kg over 2 years).
- Weight gain >10 kg after quitting may attenuate these benefits and not show significant dementia risk reduction.
- The dementia risk reduction approaches that of never smokers and plateaus around 7 years after cessation.
- Smoking cessation is linked to long-term slower cognitive decline but no transient cognitive changes.
- Study suggests weight management should be integrated into smoking cessation programs to optimize benefits.
