Caffeine-based intervention for memory and metabolic health in obesity-related cognitive decline

Overview

This research program investigates whether caffeine can improve memory and type-2 diabetes biomarkers in the context of high-fat-diet-induced obesity and cognitive decline. The work is grounded in the hypothesis that caffeine, as a bioactive dietary component, can enhance insulin protein signaling in the brain, thereby restoring memory function and other cognitive aspects affected by metabolic dysfunction. The research group brings demonstrated prior experience in nutrition, metabolism, and cognitive biomarker studies, providing a strong foundation for this investigation.

Technical specifications

Research approach:

• Phase 1 – Dose determination: Establish the appropriate caffeine dose for animal testing over a one-month period.
• Phase 2 – Animal experiments: Four experimental groups will be compared over nine months: (1) lean diet control, (2) lean diet plus caffeine, (3) high-fat diet, and (4) high-fat diet plus caffeine.
• Phase 3 – Outcome evaluation: Over a six-month assessment period, researchers will measure insulin resistance, perform cognitive and memory tests, and analyze Alzheimer-related biomarkers in the hippocampus.

Key scientific targets:

• Insulin signaling pathways in the brain
• Memory and cognitive performance metrics
• Hippocampal biomarkers associated with Alzheimer's disease
• Type-2 diabetes-related metabolic markers

Technology readiness level

This is an early-stage, preclinical research program. The hypothesis and methodology are informed by the group's published work in nutrition and cognitive function, but the specific caffeine intervention in a high-fat-diet obesity and cognitive-decline model has not yet been validated. The multi-phase validation plan (dose finding, animal experiments, biomarker evaluation) is designed to generate publishable proof-of-concept data. Industry partners are invited to co-apply for grant funding to support this research.
