Poor Cognitive Function Is Associated with Obstructive Lung Diseases in Taiwanese Adults

Area of Science:

• Pulmonary Medicine
• Neurology
• Public Health

Background:

• Previous research suggests a link between lung diseases and cognitive decline.
• The specific impact of obstructive versus restrictive lung diseases on cognitive function remains unclear.

Purpose of the Study:

• To investigate the association between cognitive function and obstructive or restrictive lung diseases in Taiwanese adults.
• To evaluate cognitive performance using the Mini-Mental State Examination (MMSE) in relation to spirometry measurements.

Main Methods:

• Utilized data from the Taiwan Biobank, including 683 participants.
• Assessed cognitive function via MMSE and lung function through spirometry (FEV1, FVC).
• Classified participants into normal, restrictive, and obstructive lung function groups.

Main Results:

• Obstructive lung function was associated with a higher prevalence of cognitive impairment (MMSE < 24) compared to normal lung function.
• Low MMSE scores significantly correlated with reduced FVC, FEV1, and FEV1/FVC ratios.
• Cognitive impairment was linked to low FEV1 in participants with obstructive patterns (FEV1/FVC < 70%).

Conclusions:

• Low cognitive function (low MMSE) is associated with impaired lung function, specifically low FEV1, FVC, and FEV1/FVC.
• Obstructive lung diseases are significantly associated with cognitive impairment, while restrictive lung diseases showed no significant association in this cohort.
