Ketone-based approaches to improve sleep, anesthesia safety, and memory in older adults
Metabolic Interventions for Sleep, Anesthesia-related Neurocognitive Disorders and Alzheimer's Disease
Looks at whether giving the brain ketone fuel can improve sleep, lower anesthesia-related brain problems, and support memory in older adults and people with Alzheimer's.

What this research studies
This research will develop metabolic approaches—such as ketone supplements or dietary strategies—to boost the brain's energy use and reduce inflammation in aging brains. Researchers will measure sleep quality, markers of brain inflammation and energy use, and cognitive function to see whether ketone-based treatments help. The work links poor sleep, anesthesia-related cognitive problems, and Alzheimer's by targeting shared metabolic and inflammatory pathways. Some experiments are likely preclinical while others will involve older adults or patient-derived samples to connect lab findings to people.
Who could benefit from this research
Good fit: Ideal candidates would be older adults with poor sleep, people facing surgery who are at risk for anesthesia-related cognitive problems, or people with early-stage Alzheimer's disease.
Not a fit: Younger people without age-related sleep or cognitive issues, or those whose problems have non-metabolic causes, are unlikely to benefit from these interventions.
Why it matters
Potential benefit: If successful, these approaches could improve sleep, reduce delirium or cognitive problems after surgery, and slow or ease memory loss in Alzheimer's disease.
How similar studies have performed: Animal studies and small human trials of ketone supplements or ketogenic diets show promising effects on brain energy and inflammation, but large trials for sleep and anesthesia outcomes or Alzheimer's are limited.
