Sleep apnea is a disorder where breathing repeatedly stops and starts during sleep, often without the sleeper being aware of the interruptions [1, 2].
This condition is critical because untreated sleep apnea can cause permanent damage to the body. It increases the risk of cardiovascular disease and cognitive decline, creating a cycle of poor health that affects millions of people [1, 2].
Dr. Randeep Guleria, Chairman of the Institute of Internal Medicine & Respiratory and Sleep Medicine and Director of Medanta Medical School, said the disorder impacts the Indian population during an NDTV Lifeline podcast [1, 3]. He said that millions of people sleep every night but never truly rest due to the condition [1].
The disorder is not limited to respiratory issues. Joanna Fong‑Isariyawongse, MD, said, "Obstructive sleep apnea is not just about snoring or feeling tired — it is very much a brain condition" [2]. This neurological connection explains why patients often experience mental performance issues and cognitive health deterioration [2].
Recent research has also identified unexpected physical changes associated with the disorder. Researchers in Israel found that people with obstructive sleep apnea tend to have a higher muscle mass index compared with those who do not have the condition [4]. The study authors said this reflects changes in muscle structure [4].
Medical professionals emphasize that while the condition is silent, it is treatable. Interventions such as Continuous Positive Airway Pressure (CPAP) therapy can improve outcomes for patients by ensuring a consistent airway during sleep [1].
“"Obstructive sleep apnea is not just about snoring or feeling tired — it is very much a brain condition."”
The classification of sleep apnea as a brain condition rather than a simple snoring habit shifts the clinical focus toward long-term cognitive and cardiovascular preservation. As research identifies systemic markers like increased muscle mass index, diagnostics may move beyond sleep studies toward broader physiological screenings to identify at-risk populations earlier.
