People who smoke, in his old age a five-fold risk of relatively more rapid memory loss compared with nonsmokers, according to recent studies.
Those who formerly smoked and now has stopped, has a two-fold risk compared with those who had never smoked. And those who smoked all his life would be faster experiencing memory loss.
The findings were to show reasons to those who smoke to quit.The reason is also necessary for those who no longer smoke, according to Dr. Lenore Launer of the National Institute of Mental Health in Maryland told Reuters Health. This finding is not the first that links between smoking and mental decline. Previous research shows that in middle age, smokers showed a tendency of memory loss and changes in memory function compared with those who did not smoke before the age of 60 years. In that study, Launer and colleagues do the testing of mental function in 9209 people aged over 65 years. They then underwent a repeat test every two years. The researchers also measured the cognitive function of study participants using the Mini-Mental State Examination (MMSE). Found that those who had never smoked showed a decline in the MMSE score three points each year. While those who smoke, MMSE score showed a decrease to 16 points per year, whereas previously they had stopped smoking and now, shrinking to six points each year. Launer explained that small changes in MMSE score according to the measurement means will result in differences in mental functioning from year to year. Smokers will be more rapid decline in her memory ability than those who do not smoke.
Moreover, the fact that smokers will shorten also showed that the effect of smoking on the brain also will eventually affect significantly to the overall public health. Smoking causes the valve blockage of blood vessels in the brain, loss of nutrients and damage to brain tissue.
