To quit smoking, even in the late stage, protected from senile dementia

In a scientific study, it was found that ceasing to smoke, even in the late stages of life, favored not only the health of the heart and lungs, but also delayed the cognitive decline and dementia related to aging and improved brain health, memory and spiritual abilities. The study, conducted by researchers at University College London and published in Lancet’s life, reported that those who stop smoking experienced a slower decrease in cognitive performance over a 6 -year period, compared to those who continued to smoke. The research team used data from 9,436 people aged 40 and older, with an average age of 58 years, from 12 countries, including England, the United States and 10 European countries, to compare the results of memory and oral fluency tests between those who quit smoking and those who continued to smoke. The results showed that the rate of cognitive decline among those who stopped was much slower than that of their smokers, as the decrease in verbal fluency decreased by about half, while the memory drop delayed by 20%. The study showed that stopping smoking, even in middle age or later, can still make a positive difference in brain health, which is an important indication of the possibility of reducing the risk of dementia and neurodegenerative diseases with age. She explained that a slow cognitive decline is associated with a lower probability of developing dementia, making smoke interruptions a possible preventative method for these diseases. However, the study team emphasized that more studies are needed to confirm the causal relationship between smoke breakdown and a lower risk of dementia. The lead author of the study, Michaela Blumberg, a researcher at the Institute for Epidemiology and Health Care at University College London, confirmed that the results of the study indicate that stopping smoking helps to maintain better cognitive health in the long run, even if at the age of 50 or later. She said: “We already know that the stop of smoking, even in later stages of life, is associated with improvement in physical health and general well -being, and it now appears that it also applies to brain health and cognitive function, which means it is never too late to quit smoking.” Bloomberg pointed out that these results are especially important because middle -aged and elderly people are less likely to stop compared to younger people, even if it is the most affected group by the long -term consequences of smoking. She explained that the presence of evidence that stopping mental and cognitive health supports can be an additional and strong incentive for this group to try to stop smoking. She emphasized that policymakers should take these findings into account when designing tobacco control strategies, because the preservation of the cognitive capabilities of the elderly is an increasing challenge in societies suffering from outdated populations. The study showed that smoking negatively affects brain health in various ways, including its direct effect on the blood vessels that provide the brain with oxygen. Smoking causes damage to the blood vessels and reduces the blood flow to the brain, which affects its important functions. It also causes chronic inflammation and oxidative stress due to the production of free radicals, which are unstable molecules that damage nerve cells. Together, these factors explain how smoking accelerates and drops in memory and concentration. Co-author Andrew Steppie, a researcher at the Institute for Epidemiology and Health Care at University College London, said the new findings contribute to the increasing evidence that smoking smoking could be an effective preventative strategy against dementia. He added that the slowdown of the cognitive decline is directly linked to a lower risk of dementia, which supports the importance of continuous awareness campaigns on the impact of smoking on the brain, in addition to the known dangers to the heart and lungs, and emphasizes that future research should focus on studying the direct relationship between the long term. Previous research on which the study team relied on indicated that people who stop smoking at the age of more than 65 can maintain spiritual abilities near those who have never smoked, and that the risks associated with dementia are gradually declining to stop the levels of non-smokers a decade or more. This data supports the idea that the brain has the ability to partially recover from the damage due to smoking, especially if it stops before severe neurological diseases occur. The study emphasized that the understanding of the relationship between smoking and brain health has become more urgent in light of the growing rate of aging around the world, and the expectations that the number of people with dementia will double in the coming decades, making the prevention one of the most important public health priorities. Although ceasing of smoking is often promoted from the perspective of heart and lung health, its positive effects on the brain can provide an additional incentive for individuals and policymakers to adopt more effective anti-smoking policies. The restoration of blood vessels The researchers have confirmed that these findings can change the way doctors give smoke interruption advice. Instead of focusing exclusively on the physical benefits, the emphasis can now be placed on the cognitive and spiritual aspects, especially among older people who feel it is too late to change. The study confirmed that it is never too late to improve brain health, and that stopping smoking can at any time make a tangible difference in the quality of spiritual life. The research team requested that the next phase of research focus on determining the extent to which the benefits of ceasing smoking last for a longer period, and that participants are followed for decades after they stop determining whether the differences in cognitive performance are actually reflected in lower dementia rate among those who stop. The researchers asked to study the exact biological mechanisms that enable the brain to recover from the damage of smoking, which can help with the development of medication or interventions that improve the neurological recovery process.
