Snoring may be a sign of obstructive sleep apnea, which means you’re having trouble breathing as you sleep. Apnea is bad for your brain, as it causes sleep deprivation, which leads to memory loss. Sleep apnea can also change the structure of your brain, damage neurons, and impact your ability to think clearly and make decisions. The good news is that much of the damage is reversible as long as the apnea is treated. If you suspect you have sleep apnea, request an evaluation from your healthcare provider and get treatment.
