Mild cognitive impairment: when nutrition helps brain energy rescue-a report from the EuGMS 2020 Congress

Area of Science:

• Neurology
• Nutritional Science
• Metabolic Research

Background:

• Mild cognitive impairment (MCI) affects individuals over 60, often goes undiagnosed, and lacks approved pharmacological treatments.
• Nutritional interventions, specifically ketogenic diets and supplements, are being explored for MCI management.
• Ketogenic interventions provide ketones as an alternative energy source for brain cells.

Purpose of the Study:

• To explore the effects of ketones on brain metabolic activity in patients with MCI.
• To investigate the mechanisms of ketogenic medium-chain triglycerides (kMCTs) in inducing ketosis for MCI.
• To review the efficacy of ketogenic supplements/diets on brain metabolism and cognitive function.

Main Methods:

• Review of existing literature on ketogenic interventions for MCI.
• Analysis of brain metabolism and ketone utilization as an energy source.
• Reference to the 6-month randomized controlled BENEFIC trial involving kMCT supplementation.

Main Results:

• Ketones serve as an efficient fuel source for the brain.
• Oral ketogenic supplements, like kMCTs, can induce ketosis.
• The BENEFIC trial demonstrated improved cognitive performance in MCI individuals consuming a kMCT drink compared to placebo.

Conclusions:

• Ketogenic supplements show promise as a nutritional intervention for MCI.
• The BENEFIC trial highlights the benefits of brain-specific ketogenic supplements on cognitive performance.
• Further long-term studies are needed to fully establish the efficacy of ketogenic interventions for MCI.
