Snoring and Dementia Risk
Snoring might pose a greater threat than simply disturbing your partner’s sleep; it could also increase the likelihood of developing dementia, according to a prominent neurologist.
In a recent video, Dr. Baibing Chen, known as Dr. Bing on TikTok, shared with his followers that this common occurrence can indeed “harm your brain.” He elaborated on how loud or nightly snoring may indicate disrupted breathing during sleep. This interruption leads to repeated oxygen deprivation to the brain, which can, surprisingly, result in minor damage to blood vessels.
Dr. Bing pointed out that these tiny injuries could be linked to silent strokes and elevate the risk of dementia in the future. MRI scans reveal that snoring can actually alter brain structure, resulting in a decrease of grey matter in regions vital for memory and cognitive functions. He mentioned that consistent snoring might lead to noticeable shrinkage in areas like the hippocampus—crucial for memory retention.
Moreover, he noted that those who snore may experience slower cognitive processing and might struggle with concentration during the day. This issue can plague even individuals without full-blown sleep apnea, a condition characterized by significant breathing interruptions at night.
Dr. Bing explained that snoring disrupts deep sleep, particularly the N3 stage, which is essential for waking up feeling refreshed. He clarified that vibrations caused by snoring could nudge the brain awake—even if it’s not remembered. Consequently, this can diminish restorative sleep, preventing the brain from carrying out its necessary overnight repair work. So, it’s not just a nuisance for your partner; it’s actually affecting how your brain functions.
Medical experts have previously indicated that snoring poses risks for hypertension, heart disease, stroke, and type 2 diabetes as well.
A number of social media users flooded the comments with a burning question Dr. Bing didn’t address: how to stop snoring. One follower humorously pointed out that he left out the essential advice on what to do about it.
Simple lifestyle adjustments can make a difference, and the NHS states that factors like smoking, being overweight, and excessive alcohol consumption are linked to snoring. Additionally, it becomes more likely when sleeping on your back. Many people in the UK are estimated to suffer from sleep apnea, with obstructive sleep apnea being more common than its central counterpart.
Obstructive sleep apnea occurs when throat muscles excessively relax, thus partially or fully blocking airflow, while central sleep apnea arises from the brain’s inability to send the correct signals to breathing muscles during sleep.
Previously, Dr. Pavol Surda, a specialist in sleep-related breathing disorders, emphasized that treatment is available. He recommended consulting a professional if there’s any suspicion of sleep apnea since specialists can perform comprehensive evaluations, often involving sleep studies. Treatment can vary based on severity, encompassing lifestyle changes, CPAP therapy, oral devices, or, in certain cases, surgery.
