Older Age and Obstructive Sleep Apnea (OSA): Mechanism

Older age is recognized as a risk factor for obstructive sleep apnea.[1]

But why? Suspected physiologic changes with older age that increase the risk of apnea: increased collapsibility of the upper airway, reduction in genioglossus muscular tone, and reduced upper airway dilator muscle activity/responsiveness.[2,3,4]
