- Memory function is compromised by tobacco smoke and e-cigarette vapour.
- Both pollutants cause oxidative stress and inflammation in the brain, leading to synaptic injury and neuronal apoptosis.
- Younger populations are at higher risk, with potential early-onset dementia.
- Third-hand exposure (via surfaces or clothing) poses significant risks, especially to toddlers.
- Epigenetic mechanisms like DNA methylation and histone modification worsen these effects.
- Further research is needed to develop risk-reduction strategies for cognitive health.
