Smoking is responsible in reducing the
volume of some brain regions, which
can result in aging the brain faster.
Researchers suggested that smoking appeared to speed up the thinning of the outer layer of the brain (cortex), seen in normal brain ageing. This can badly affect important areas of our cognitive skills i.e. thinking patterns, planning, decision-making and problem-solving. It was found that participants who were engaged in the study and they had given up smoking appeared to have a thicker cortex than more recent quitters. Results suggested that if people start avoiding smoking, it can help them maintaining the normal thickness of the cortex, protecting against age-related cognitive decline. Most of the people think that smoking an only cause physical damages, i.e. affects lung health, heart, but they should be aware of all the psychological damages and how smoking an also increase their risk of dementia. Earlier research done on smoking revealed that it can reduce the volume of some brain regions and, therefore which can result in aging the brain faster. Evidences suggested that smoking puts people at a greater risk of developing dementia than those who have never smoked, but this is reversible, you can meaningfully minimize by quitting the habit. One good thing for the people who got into this problem is that brain volume can recover after smoking cessation.
Smoking does affect our brain and body in a very damaging way, but quitting smoking could help in reversing the damaging effects it has.
