Do not take snoring casually, as it is a symptom of a disorder which makes the oxygen level drop and affects crucial parts of your brain. Snoring has become a bedroom nuisance, where the loud, wacky sounds keep the other person awake, staring at the ceiling in frustration. Some may even call it a relationship deal-breaker. But what many do not realise is that this symptom points to an underlying health condition, which may be connected to a chain effect of health conditions. So instead of getting irritated, consider addressing the situation with empathy and a medical perspective.ALSO READ: Neurologist explains difference between normal forgetfulness and dementia memory loss: ‘If it gets worse over time…’Don't ignore snoring! (Picture credit: Pexels)To bring in a more serious perspective, did you know snoring is linked to brain health and possible dementia risk? Giving much-needed clarity on this alarming association, Dr Pramod Krishnan, HOD and consultant, neurology, epileptology and Sleep Medicine at Manipal Hospital, Old Airport Road in Bengaluru, weighed in with expert insights on why you should not be casual about someone snoring in your household, let alone dismiss it as an annoyance. In reality, snoring is a symptom of a sleep disorder which is serious enough to adversely affect brain health and cause life-threatening conditions.Why should you never ignore snoring?Headache is common. (Freepik)The neurologist advocated for empathy as he recounted the wide evidence linking this ‘habit’ to actually being a symptom of a sleep disorder, “Growing scientific evidence suggests that it is no laughing matter and may indicate a serious underlying sleep disorder called obstructive sleep apnea (OSA).”He elaborated that OSA, aside from loud habitual snoring, has other signs and symptoms which may sometimes overlap with other ailments. Some of them include:Non-refreshing sleepExcess daytime sleepinessMorning headacheGrogginess in daytime, leading to poor functioningWhat's worse is that when these symptoms don't show up. “Simple snoring without these accompanying symptoms is less concerning,” Dr Krishnan overtly expressed his concerns over why snoring is the worst symptom of all for sleep-related disorders.How can snoring cause stroke or dementia?Next, he gave a clinical description of what happens to your body as you suffer from this sleep disorder: “In people with OSA, there is fragmentation of sleep due to repeated drops in blood oxygen saturation caused by upper airway obstruction, and the breath seems to repeatedly stop and start throughout the sleeping period.”Since your sleep is disrupted time and again throughout the night, your sleep quality plummets, because of which you are at risk of neurodegenerative diseases. “The poor-quality sleep night after night elevates the risk of a myriad medical problems, including those affecting brain health like stroke and dementia,” the neurologist added.Like a domino effect, since the body is so interconnected, other areas can get affected, where a simple symptom like snoring, which is viewed more as an irritation than a health symptom, may actually be a risk factor for dementia and life-threatening conditions like stroke.Which cognitive functions get damaged?Memory loss occurs because of OSA.

And memory loss is one of the telltale signs of neurodegenerative diseases like dementia. But why are memory areas, the hippocampus/amygdala, getting affected?Dr Krishnan answered, “Repeated oxygen drops can trigger inflammation, oxidative stress, and injury to neurons. Especially in areas involved in memory and other cognitive functions. Cognitive testing has consistently linked OSA to suboptimal cognitive performance in many affected individuals across several domains, including attention, executive function, processing speed, and memory."What are the treatments for OSA?It is crucial to address the sleep disorder immediately, especially if you observe someone's recurrent snoring. The neurologist named some therapies, such as continuous positive airway pressure (CPAP) therapy (treatment of choice) which is the treatment of choice, along with weight loss.Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.
