You Smoke You Damage Your Brain that Responsible for Memory, Language and Perception


A study by scientists in Edinburgh and Montreal found smokers have brain cortex is thinner than non-smokers. The cortex is the outer layer of the brain where the important cognitive functions such as memory, language and perception occurs. Research shows that the cortex is likely to re-thick smokers kick the habit of smoking, and it is not seen in all parts of this otak. Penelitian collect health data from 224 men and 260 women with an average age of 73, about half of whom were former or current smokers .

By using MRI brain scans detailed, careful image analysis and statistical models show that this analysis shows how a person smoking habits affect the thickness of brain cortex

Professor Ian Deary, from the University of Edinburgh, who led the research, said: '' It is important to know what is associated with brain health in older age.

'From the data Reviews These have we found a small link between smoking and having thinner brain gray matter in some regions.

'There are findings in our study that could suggest that stopping smoking MIGHT allow the brain's cortex to recover some of its thickness, though we need further studies are conducted with repeat measures to test that idea.'

Dr. Sherif Karama, an assistant professor of psychiatry at McGill University, added: 'We found that current and ex-smokers had, at age 73, many areas of the brain cortex thinner than Reviews those that never smoked.

'Subjects WHO stopped smoking seem to partially recover Reviews their cortical thickness call now for a year without smoking.'

Clear recovery process is slow though, and incomplete, she said.

 
cortex is the outer layer that covers two-thirds of the brain mass. also known as gray matter, the most a highly developed, most functions to think, observe, produce and understand language
A thin brain cortex associated with cognitive decline in adults.
Dr. Karama, added: "Smokers should be informed that cigarettes could Hasten the thinning of the brain's cortex, the which could lead to cognitive deterioration.

The Researchers found Those who had quit smoking for a long period of time has a Thicker cortex, Compared with Those who had just stopped. even after taking into account the total amount of smoking in Reviews their lives.
 
Professor Joanna Wardlaw, director of the Brain Imaging Research Centre at the University of Edinburgh, said: 'The effects of smoking on the lungs and heart are well known, but our study shows that there are important effects on the brain as well, another good reason for not smoking. '

Professor James Goodwin, head of research at Age UK, added: 'Understanding how and why our thinking skills change with age is a major health challenge.'This current work helps us to understand how smoking Affects the brain in later life. 'The more we can find out about what influences our thinking skills as we age, the better the advice we can give people on protecting Reviews their cognitive health.'

The study published in the journal Molecular Psychiatry, and is part of a larger project called Disconnected Mind supported by a grant from Age UK.
