Stop This Bad Habit or You Might Experience Memory Loss by Middle Age

Smoking is harmful to your health for many reasons, including damaging your lungs and causing diabetes. Researchers have recently discovered yet another reason.

A study by the Ohio State University found that smokers are more likely to suffer from memory problems and cognitive impairments in their middle age. The study found that ex-smokers with a successful quitting habit are less likely to experience brain degeneration.

The study published in the Journal of Alzheimer’s Disease confirms previous research’s findings that smoking cigarettes is linked to various forms of dementia.

Participants answered a simple question to indicate whether they experienced issues such as confusion or memory loss. The researchers compared the subjective cognitive decline rates of current smokers, quitters who quit recently, and those who quit long-term in a sample consisting of 135,000 people aged 45 or older.

According to Neuroscience news, smokers’ subjective cognitive decline is nearly 1.9x higher than nonsmokers. Ex-smokers quit smoking within the last decade had a 1.5 times higher relapse rate compared to nonsmokers. The prevalence of SCD was slightly higher in people who had quit smoking more than 10 years prior to the survey than it was for never-smokers.

What are the harmful effects of smoking?

There are many other harmful effects that smoking can have.

Brain Volume

In 2017, researchers found that smokers experience a rapid decline in their brain volume with age.

Smoking was found to negatively affect the structural stability of subcortical regions. They also found that smokers had more volume loss due to age in different brain regions.


Smokers are more likely to suffer a stroke than non-smokers. According to the Centers for Disease Control and Prevention, smoking cigarettes can double or quadruple stroke risk in men and women. The more cigarettes you smoke each day, the greater your stroke risk.


Smoking can introduce toxic chemicals into the brain and body, including some which cause cancer.

According the the medical director at Wellbridge Addiction Treatment and Research, genetic abnormalities of the throat, lungs or brain can increase the risk of developing cancer after prolonged tobacco use.

Does Quitting Make A Difference?

According to research published in 2018, long-term exsmokers are less likely to develop dementia. A separate study found that, while it might take some time to see results, quitting smoking leads to structural changes in the cortex of the brain.

Smoking cessation has many positive effects on health. This includes improvements in your brain. It can, for example, lower the carbon monoxide level in your blood within 12 hours after smoking your last cigarette. It can also slow your heart rate.
