Snoring loudly could be a harbinger of dementia and memory problems, scientists say.
People with obstructive sleep apnea often cause severe snoring and have brain disorders related to dementia. a study found.
At least half a million Britons suffer from the disease, which is common among overweight middle-aged men and causes closure of the throat walls during sleep, stopping breathing
Scientists say loud snoring could be a harbinger of dementia and memory problems [19659007] Scientists at the University of Sydney now suggest that it could reduce parts of the brain by reducing oxygen levels in the blood.
The study found that those who had sleep apnea had a reduced thickness in their left and right temporal lobes, which are memory centers of the brain and related to dementia.
These brain changes were linked to poor performance in a memory test where people received a list of 15 items and asked to be recalled after 20 minutes
Professor Sharon Naismith, who was leading study from the Brain and Mind Center of the University of Sydney, said, "Our findings suggest that we should be screening for obstructive sleep apnea (OSA) in the elderly."
: "We should also ask older patients who attend sleep clinics about their memory and thinking skills and perform tests if necessary.
"There is no cure for dementia. On the other hand, we have an effective treatment for OSA. This research shows that diagnosing and treating OSA could be an opportunity to prevent cognitive decline before it is too late.
Australian researchers recruited 83 people over the age of 50 who are concerned about memory problems in a sleep clinic. The participants were sleeping normally while the airflow through the nose and the oxygen level in the blood were recorded.
On an index of sleep apnea, 63 of 83 had a mild to severe state of the state. had a reduced thickness in their left and right temporal lobes, which are memory centers of the brain and related to dementia ” clbad=”blkBorder img-share” />
The study found that sleep apnea had a reduced thickness in their left and right temporal lobes, which are memory centers of the brain and related to dementia
. The results published in the European Respiratory Journal those who had low levels of oxygen in the blood had reduced gray matter in their temporal lobes. This loss of brain volume has been linked to devastating memory loss in patients with dementia.
And if the study was not about dementia, it showed that people Professor Naismith said, "Between 30% and 50% of the risk of dementia is due to modifiable factors such as depression, high blood pressure, obesity and smoking
. researchers have recognized that various sleep disturbances are also risk factors for dementia.
Sleep apnea can be treated with the help of a continuous positive pressure device, which prevents the closure of the airways during sleep.
