Smokers Are ‘Much More Likely To Develop Dementia’, Docs Warn

 

Smoking has previously been linked to inflammation in the body, which can lead to a number of diseases including dementia

PUFFING on fags increases your risk of dementia, new research suggests.

Those who don't smoke, or had quit smoking, had less chance of developing the degenerative brain condition than those who still smoke cigarettes, according to a Korean study.

Those who smoke are at a greater risk of dementia than those who don't smoke, new research suggests

 

Those who has smoked long-term but recently quit had a 14 per cent less chance of developing Alzheimer's later in life.

They also had a 32 per cent reduced chance of developing vascular dementia - one of the most common forms of the disease.

While those who had never smoked had 19 per cent less chance of developing Alzheimer's and a 29 per cent less chance of developing vascular dementia.

The study, published in the Annals of Clinical and Translational Neurology followed 46,140 men aged over 60 who took part in a Korean health screening.

"Smoking cessation was clearly linked with a reduced dementia risk in the long term, indicating that smokers should be encouraged to quit in order to benefit from this decreased risk," said senior author Dr. Sang Min Park, of Seoul National University, in Korea.

Smoking has previously been linked to inflammation in the body, which can lead to a number of diseases including heart disease, stroke and cancer.

Dementia and Alzheimer's have also been linked to inflammation.

Vascular dementia is the second most common type of dementia in the UK after Alzheimer's disease, where the brain is damaged due to a lack of blood flow.

If the vascular system within the brain becomes damaged - so that the blood vessels leak or become blocked - then blood cannot reach the brain cells and they will eventually die.
The toxins in cigarettes can cause this kind of damage to blood vessels.
This death of brain cells can cause problems with memory, thinking or reasoning, and when these cognitive problems are bad enough to impact on daily life, it is known as vascular dementia.
There are several different types of vascular dementia, due to the varying levels of damage on the affected part of the brain.

They include stroke-related dementia, single-infarct and multi-infarct dementia, subcortical vascular dementia and mixed dementia - which includes both vascular and Alzheimer's disease.
