Studies suggest nearly 60 percent of people with OSA experience some degree of cognitive impairment, including difficulties with attention, working memory, and episodic memory. Mood disorders such as depression and anxiety are also more common. Over time, untreated sleep apnea has been linked to declines in concentration, executive function, and long-term memory. So what's actually happening inside the brain while someone with undiagnosed sleep apnea sleeps?
Sleep apnea is one of the most common - and most overlooked - sleep disorders. Millions of people live with it for years without realizing their nightly rest is being repeatedly disrupted, quietly affecting their health in ways that extend far beyond sleep. Once you know what to look for, the signs may sound familiar: getting a full eight hours yet waking up exhausted, struggling with daytime fatigue, irritability, and difficulty concentrating.
