Obstructive sleep apnea syndrome may increase risk of dementia, reveals research
A new study published in the BMJ Thorax journal showed that obstructive sleep apnea syndrome (OSAS) may be linked to an increased risk of all-cause dementia, especially vascular dementia, according to major research of 2.3 million individuals in the UK.
More than 55 million individuals worldwide suffer with dementia, which is an illness that mostly affects the elderly and causes cognitive decline. It is presently the 6th greatest cause of mortality. More research is warranted to identify and reduce other modifiable risk factors that are causally linked to the future risk of dementia, as only around one-fifth of the disability-adjusted life years linked to dementia can be attributed to known modifiable risk factors.
Both dementia and OSAS are common in the elderly population. According to scientific data, OSAS is linked to neurovascular injury and neurodegenerative processes, which can eventually result in dementia and cognitive impairment. The patients at risk for dementia have been advised to have OSAS assessed and treated. Still, not everyone agrees that OSAS is a modifiable risk factor for dementia.
Furthermore, it is yet unknown if treating OSAS can lower the risk of dementia or decrease cognitive decline. Determining whether particular features of OSAS are linked to cognitive outcomes is crucial because of the disease's diverse character. Thus, this study by Jingya Wang and colleagues was to compare the risk of dementia in people with and without OSAS.
