Smoking literally rots the brain, destroying memory and the ability to learn and reason in older adults, a new study has found.

The study, published in the journal Age and Ageing, shows that an unhealthy lifestyle can damage the brain.

Researchers at King's College London had 8,000 people over the age of 50 perform cognitive tests to measure their memory and brain function.

After four years, the smokers and people at a high risk of stroke performed much more poorly on the tests, showing accelerated cognitive decline. After eight years, people with high blood pressure scored lower on the tests.

"Some older people can become forgetful, have trouble remembering common words or have problems organizing daily tasks more than others," Dr. Alex Dregan said.

"We have identified a number of risk factors which could be associated with accelerated cognitive decline, all of which, could be modifiable. This offers valuable knowledge for future prevention and treatment interventions."
