There has been little in the way of progress for treatments that reverse dementia. Until now. A 2025 study reports that ketone esters are a groundbreaking treatment for Alzheimers. I have posted an abstract of the review study below for your inspection.

About Ketone Esters
The brain is fueled by two sources: glucose and ketones. Glucose is produced in the body when eating carbohydrates. Ketones are produced by the liver when fasting and when eating foods that have a high fat content.
Of the two sources of fuel for the body, ketones are preferred over glucose when it comes to problems with memory. Think of ketones as clean fuel and glucose as “sticky” fuel. Do you want your brain to be energized by clean fuel or sticky fuel? I prefer clean myself. Of course, we need both but when it comes to a high functioning memory, ketones are a preferred source of fuel over glucose.
Ketone Esters: a New Option for Treatment of Alzheimers
Researchers have known since the turn of the century that ketones are a beneficial therapy for brain disorders. The challenge has been that until the last several years, the cost of manufacturing a gram of ketones was $1,000. No one could afford this!
Researchers finally discovered a way to make ketones in the lab. They have now been available commercially for about a decade.
The first group to begin taking the ketone esters enthusiastically has been professional athletes who experience a 10-15% increase in performance from taking the ketone esters. They have now been found to be beneficial as a treatment for Alzheimers as documented in the study below.
MedRxiv. 2025 Sep 18:2025.09.17.25335999. The Effect of Exogenous Ketone Bodies on Cognition in Patients with Mild Cognitive Impairment, Alzheimer’s Disease and in Healthy Adults: A Systematic Review and Meta-Analysis
Abstract
Importance: Impaired cognitive function is a hallmark of neuropsychiatric disease, posing a significant challenge to patients, clinicians and healthcare systems. Emerging research on ketone bodies suggests they may function as an alternative fuel for the brain, potentially enhancing cognitive function through both metabolic and signaling pathways. An alternative to inducing ketosis by lowering dietary carbohydrate intake is consumption of exogenous ketones (EK).
Objective: It is unknown whether the existing literature collectively supports a beneficial effect of EK on cognitive function; this systematic review and metanalysis aims to aggregate available data and address this gap.
Data sources: PubMed, Web of Science, and EMBASE databases were searched in October 2023 for key words and free words referring to ketone bodies, cognition, and health-related conditions.
Study selection: Multiple reviewers selected 29 studies for inclusion in the analysis from the initial 1678 search results, which included randomized control studies of healthy participants and patients with neuropsychiatric conditions, using exogenous ketones as an intervention alongside a placebo, that included outcomes assessing cognitive function.
Data extraction and synthesis: A PRISMA model was used for abstracting data, and the PEDRo scale was used to assess study quality. Data was extracted and verified by independent investigators.
Main outcome: Cognitive function measures.
Results: 29 studies (1,347 participants) were included, with 18 studies (875 participants) in the meta-analysis. Results indicate that EK administration has a modest but statistically significant positive effect on cognitive performance (SMD = 0.26, 95% CI: 0.11 – 0.40, p = 0.0007). Sub-group analyses showed no significant differences between study duration (acute vs. intermediate; p = 0.50), ketone form (mono-esters vs. medium-chain triglycerides; p = 0.06), population type (healthy vs. Alzheimer’s disease; p = 0.21), or the presence of acute cognitive stressors (p = 0. 25).
Conclusions: The findings suggest that EK could be a promising adjunctive strategy in dementia management, offering potential benefits even in patients who maintain sufficient carbohydrate intake. EK may provide psychiatrists with an innovative, non-invasive approach to supporting cognitive resilience in patients with neuropsychiatric disorders.
