Smoking increases the risk of loss of memory
Smoking seems to be related with the increased risk of memory loss and dementia in middle-aged people, show the results of a French investigation, quoted by France Press.
Medics from the French National Institute for Health and Medical Research in Villejuif, France have analyzed medical data from 10 308 British employees, aged between 35 and 55 years that have taken part in the study between 1985 on and 1988.
The group of smokers was identified at the beginning of the study and once again between 1997 and 1999.
Total 5388 participants were subjected to tests of memory, mind, clearness of expression between 1997 and 1999. 4659 people of this group were tested again 5 years later.
The results of the tests were compared with those of non-smokers and participants that refused cigarettes.
“For those participants who have smoked at the beginning of the study had a higher risk to die during the average 17 years long period of monitoring of their health and therefore fewer chances to take part in the second test of mental abilities, said the chief author of the study, Dr. Severin Sabiya.
During the first test of mental abilities, smokers were those 20 percent who showed the poorest results.
Those who gave up smoking during the study, the tests showed improvement in their life, resulting in drinking less alcohol, increased physical activity and more frequent consumption of fruits and vegetables.
The authors of the study note that the relation between smoking and mental abilities in the group of the older participants can hardly be established, because many of them didn’t make the second test, because of illness.
The study suggests that smoking is related with the loss of memory and decrease of mental abilities in middle-aged people. The results of the investigation are published in the Archives of Internal Medicine.
