Smoking in males appears to be connected with more fast cognitive decline, as per the reports printed by Archives of General Psychiatry, an online periodical. Smoking is greatly predicted as a risk factor for disease dementia for the elderly individuals and the cases of dementia in the year 2010 was estimated around 36 million. This figure is still mounting and is expected to double every 20 years, submitted by the researchers. Severina Sabia and her colleagues studied the Whitehall II cohort study and examined the relationship between the cognitive decline (while it transits from middle to old age) and smoking history. Data was obtained from 2137 women and 5099 men with an average age of 56 years at the assessment of first cognition.
In a recent study, the researchers scrutinized the data by making use of six evaluations of smoking status since the last 25 years and about three cognitive evaluations from the last 10 years. The researchers found that their analysis showed four principle findings. They recommend that smoking in males is connected with more fast cognitive decline and that males who still continued smoking after the follow-up experienced much greater decline in various cognitive tests.
The Alzheimer’s Association defines Mild cognitive impairment (MCI) as a condition in which a person has problems with memory, language, or another mental function severe enough to be noticeable to other people and to show up on tests, but not serious enough to interfere with daily life. Research has shown that individuals with MCI have an increased risk of developing Alzheimer’s disease over the next few years, especially when their main problem is memory. Not everyone diagnosed with MCI goes on to develop Alzheimer’s. There is currently no treatment for MCI approved by the FDA.
Also men who made efforts and quitted smoking in the last 10 years, foregoing the initial cognitive calculation were still at high risk of elevated cognitive decline. This was particular in the executive function. However faster cognitive decline was not shown in long term ex smokers. But the results finally demonstrated that the relationship between the cognition and smoking especially in elder individuals is possible to be underestimated owing to the elevated risk of mortality and dropout amongst the smokers. The researchers point that their results prove no relationship between cognitive decline in women and smoking. The reasons remain undefined. The only difference which the researchers could point was that males smoke much tobacco than women.
