A new study investigated the link between cigarette smoking and brain volume in 32,094 participants of European descent using the UK Biobank dataset. The results indicated a strong link between a history of daily smoking and decreased brain volume, with heavier smoking associated with a greater decline.
The most significant impact was observed in total gray matter volume. Additionally, a genetic risk score for smoking initiation was linked to a history of daily smoking, but only modestly associated with total gray matter volume. Overall, the study supports the idea that a history of daily smoking is strongly connected to a reduction in total brain volume.
"There was no evidence of an increase in brain volume following smoking cessation. ... These findings provide additional evidence that a history of daily smoking is strongly associated with long-term global adverse consequences in the brain," concluded the investigators.
