Risk factors for Alzheimer's disease in Russia: a case–control study

The most important risk factors for AD in the Russian community are family history of parkinsonism, hypothyroidism and a history of head trauma with loss of consciousness.

Cigarette smoking is a risk factor for Alzheimer's Disease: an analysis controlling for tobacco industry affiliation.

The available data indicate that smoking is a significant risk factor for AD and that smoking protects against AD.


A systematic review and original data support the idea that the mechanism underlying the epidemiological association of cigarette smoking with AD might involve the effect of cigarette smoke on APP processing, a reduction of Aβ clearance by microglia, and/or an increased microglial proinflammatory response.

Isolated and joint effects of tobacco and alcohol consumption on risk of Alzheimer's disease.

A protective effect of alcohol consumption is suggested, mostly in non-smokers, and the need to consider interactions between tobacco and alcohol consumption, as well as interactions with gender, when assessing the effects of smoking and/or drinking on the risk of AD.

A Systematic Review of Meta-Analyses that Evaluate Risk Factors for Dementia to Evaluate the Quantity, Quality, and Global Representativeness of Evidence

There is a lack of midlife specific data, limited data on VaD, and a lack on geographical representation for many risk factors for dementia, which needs to be considered before recommendations are made about the relevance of risk factors in mid- or late-life or for dementia subtypes.

Lifestyle-related Risk Factors Associated with Alzheimer's Disease: A Systematic Review of the Literature

Results of the de novo systematic review indicated that the available evidence was inadequate to suggest an association between stress and risk of AD, and too few studies were identified in the updated systematic review on Mediterranean diet adherence to allow for definitive conclusions.

Different Exposures to Risk Factors Do Not Explain the Inverse Relationship of Occurrence Between Cancer and Neurodegenerative Diseases: An Italian Nested Case-control Study

Different exposures to nongenetic risk factors of both diseases do not explain their competitive relationship of occurrence, and cancer was found inversely associated with the risk of AD/PD.

Tobacco smoking and risk for dementia: evidence from the 10/66 population-based longitudinal study

Abstract Objective: This study aimed to estimate the association between tobacco smoking and risk for dementia in seven low- and middle-income countries. Methods: Secondary analysis of the 10/66

Smoking as a risk factor for dementia and cognitive decline: a meta-analysis of prospective studies.

It is concluded that elderly smokers have increased risks of dementia and cognitive decline and the groups were not different regarding risk of vascular dementia or any dementia.



Smoking and risk of dementia and Alzheimer's disease in a population-based cohort study: the Rotterdam Study

The influence of smoking on the risk of Alzheimer’s disease

The results are consistent with the observation that smoking increases the risk of Alzheimer’s disease, however, it is found that among previous smokers who quit smoking, there may be a slight reduction in therisk of AD.

Smoking and Alzheimer's disease: a review of the epidemiological evidence.

  • P. Lee
  • Biology
  • 1994
Overall evidence from 19 case-control studies of Alzheimer's disease and smoking shows a highly significant negative association and is consistent with other data suggesting nicotine protects against AD.

Smoking as a Risk Factor for Alzheimer's Disease

It appears that this study includes the largest group of Alzheimer’s disease patients studied with respect to smoking, and findings indicate that people who used tobacco developed Alzheimer‘s disease an average of two years earlier, but these findings were not statistically significant.

Risk factors in clinically diagnosed presenile dementia of the Alzheimer type: a case-control study in northern England.

No significant relationship between exposure to aluminium in water supplies, tea, and antacids was found; however, the bioavailability of all dietary aluminium, determined by the concentrations of dissolved silicon in water, requires further investigation.

Rates and risk factors for dementia and Alzheimer’s disease

Female gender, current smoking, and low levels of education, and current smoking increased the risk of AD significantly, while head trauma was not a risk factor for AD, and smoking did not protect against AD.

Smoking and the occurrence of Alzheimer's disease: cross-sectional and longitudinal data in a population-based study.

Smoking does not seem protective against Alzheimer's disease or dementia, and the cross-sectional association might be due to differential mortality.

Risk factors for Alzheimer's disease: a case-control study.

A case-control study of 98 AD patients and 98 age- and sex-matched controls found factors associated with AD included the presence of apolipoprotein epsilon4 allele, and the duration of well water consumption.

Risk factors for clinically diagnosed Alzheimer's disease

Dementia among first- or second-degree relatives and advanced age of the mother at subject's birth (age over 40) were associated with AD, but the previously reported association with antecedent thyroid disease or family history of Down's syndrome was not confirmed.

Alcohol and tobacco consumption as risk factors for Alzheimer's disease: a collaborative re-analysis of case-control studies. EURODEM Risk Factors Research Group.

A statistically significant inverse association between smoking and Alzheimer's disease was observed at all levels of analysis, with a trend towards decreasing risk with increasing consumption and a propensity towards a stronger inverse relation among patients with a positive family history of dementia.
