Sleep homeostatic mechanisms, specifically the increase in EEG slow-wave activity (SWA) following sleep deprivation, remain operative in older adults, although baseline and recovery SWA levels are lower than in young adults.
Older adults still build up sleep pressure (homeostasis) effectively, but the resulting deep sleep (SWA) is less intense than in youth. This contributes to fragmented sleep.
GoodQualifiesHIGH confidence
Sleep-homeostatic mechanisms, as assayed by the sleep-deprivation-induced increase of EEG slow-wave activity (SWA), are operative in older people, although during both baseline sleep and recovery sleep SWA in older people remains at lower levels.
Why this rating
Based on sleep-deprivation protocols and EEG analysis.

- Age-related early morning awakening and reduced sleep consolidation are driven by an internal phase advance of the circadian pacemaker and a reduction in the amplitude of the endogenous circadian component of core body temperature, rather than a shortening of the intrinsic circadian period.Good
- The amplitude of the endogenous circadian component of core body temperature is significantly reduced in older adults compared to young adults, contributing to reduced sleep consolidation.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
