Alzheimer's & Dementia: Pulmonary dysfunction actually affects cognitive ability

Pulmonary function test (PF) is a test used to assess the vital capacity and breathing capacity of patients with respiratory diseases

PF is an important parameter for a complete assessment of the respiratory system and can be measured with a spirometer

A growing body of evidence suggests that impaired lung health may be related to a rapid decline in cognitive ability and an increased risk of Alzheimer’s

In view of these conflicting results, the impact of lung function on the long-term trajectory of cognitive function is still unclear, especially because previous studies often used a single PF indicator and the follow-up time was relatively short (3-19 years)

Population Research Flow Chart

Recently, in the Rush Memory and Aging Project (Rush Memory and Aging Project), researchers followed 1,377 subjects without dementia for 21 years

Researchers have found that low PF is related to the rapid decline of overall cognition and specific domain functions , including explicit memory, semantic memory, working memory, visuospatial ability, and perception speed
