Association of passive smoking with cognitive impairment in older adults is unclear. We carried out a systematic literature review and a new study to determine the association. There were 3 cross-sectional studies published, showing a significant association of passive smoking with cognitive impairment (a relative risk (RR) of about 1.30-1.90). In the new cohort study, we interviewed 1081 never-smoking participants aged ≥ 65 years in China using a standard method of the Geriatric Mental State…

Passive Smoking Exposure in Living Environments Reduces Cognitive Function: A Prospective Cohort Study in Older Adults
There is currently no consensus regarding the effects of passive smoking exposure on cognitive function in older adults. We evaluated 7000 permanent residents from six regions within Zhejiang…
Passive smoking as a risk factor for dementia and cognitive impairment: systematic review of observational studies
TLDR
There is limited weak observational evidence linking passive smoking with an increased risk of cognitive impairment or dementia, however, the studies were methodologically diverse and of inconsistent quality, preventing firm conclusions.
Secondhand smoking and neurological disease: a meta-analysis of cohort studies
TLDR
Secondhand smoking was found to be positively associated with risks of stroke and cognitive impairment, while inversely associated with risk of PD, and suggests that more researches on biological mechanisms whereby secondhand smoking affect PD may be beneficial to PD prevention and treatment.
Exposure to secondhand tobacco smoke and the frailty syndrome in US older adults
TLDR
In the US nonsmoking older adult population, exposure to SHS was associated with an increased frequency of frailty, and more efforts are needed to protect older adults from SHS, especially at home and in other areas not covered by smoke-free regulations.

Relation of Secondhand Smoking to Mild Cognitive Impairment in Older Inpatients
TLDR
Evaluated the prevalence of SHS in hospitalized older patients with cognitive deficit, particularly in those with mild cognitive impairment (MCI), and patients with MCI showed a significantly higher frequency of active and secondhand smokers than patients with dementia or C.
Effect of smoking on global cognitive function in nondemented elderly
TLDR
Higher rates of decline by smoking were found in men and women, persons with and without family history of dementia, and in three of four participating studies, suggesting smoking may accelerate cognitive decline in nondemented elderly.

TLDR
Exposure to secondhand smoke may be associated with increased odds of cognitive impairment and Prospective nationally representative studies relating biomarkers of exposure to cognitive decline and risk of dementia are needed.
