Smoking can also cause dementia

Reading time: 1 minute

We all get smoking is bad for us—but it could be even worse than we thought.  It interferes with our ability to memorize and learn and increases our risk of dementia, new research has found.

Cognitive decline is a bigger threat for women, while male smokers are more likely to suffer from heart disease.

Although the risk is different between the sexes, the two conditions are linked; cardiovascular disease impacts verbal learning and memory, as can be seen in cases of VCID (vascular contributions to cognitive decline and dementia).

Researchers from the Translational Genomics Research Institute in California tracked the health of more than 70,000 people around the world who were aged from 18 to 85.  Although cognitive decline had already started in even the youngest smokers, it’s never too late—or soon—to quit, the researchers say. 

Overall, smoking is the leading cause of preventable disease and death, and is responsible for one in five deaths.
