MINNESOTA, November 28 – New US research has found that middle-aged adults with lung disease may have more risk of developing dementia or cognitive impairment later in their lives. Leading researchers at the University of Minnesota, the study analyzed data data of 14,184 participants with an average 54-year-old participating in the Atherosclerosis Risk in Communities (ARIC) study.
Participants were followed for an average of 23 years, and during that period, they completed inspirational tests, which examined the function of the lungs, answered questions about their lung health, and was assessed for dementia or cognitive impairment.
The findings, published in the Journal Journal of Medical Care Respiratory and Critical, adults with restrictive lung disease or obstruction also had an increased risk of dementia, including Alzheimer's disease, and mild cognitive impairment.
For those with limited lung disease, such as idiopathic pulmonary fibrosis and sarcoidosis, the risk of dementia or mild cognitive impairment was 58 percent higher than for those without lung disease, and 33 per cent higher Among those with lung disease is a barrier.
There are low results on two tests of spirometry – an inhalation volume in one second (FEV1), or the amount of air that an individual can explete is compulsory in one moment, and the essential capacity (FVC), or the total air a person is able to defeat it compulsory – also associated with dementia.
The authors suggested that both conditions may be linked because lung disease can produce low blood oxygen levels, which could lead to incidence, stress and damage to brain blood vessels.
The researchers noted that the study has its limitations, and can not prove a cause and effect relationship between lung disease and dementia or mild cognitive impairment. However, if the relationship is causal, it could mean improving air quality and helping people to give up the cessation, not only can reduce the rates of lung disease but also dementia.
"Depression of dementia is a public health priority, and previous studies have suggested that the poor health of the lungs, which is often stopped, can be linked to a greater risk of developing dementia," said Dr Pamela L. Lutsey, lead study author.
"Preventing lung disease is crucial," said Dr. Lutsey. "If other studies confirm the findings of our study, individuals and policy makers will have an additional incentive to make changes that protect the health of the lungs, in doing so, it can also prevent prejudice." – AFP-Relaxnews
