About this trial
This study investigates the effects of a symbotic supplement (Inulin + Lactobacillus acidophilus) on cognitive impairment in older adults with type 2 diabetes mellitus (T2DM). Diabetes is a chronic disease characterized by insulin deficiency or resistance, leading to hyperglycemia and long-term complications, including cognitive decline. Cognitive impairment in T2DM patients is linked to oxidative stress, neuroinflammation, and disrupted insulin signaling in the brain.
The gut-brain axis plays a crucial role in cognition, with gut microbiota influencing neuroinflammatory processes. Dysbiosis, common in T2DM, exacerbates cognitive decline. Probiotics like Lactobacillus acidophilus and prebiotics like inulin can restore gut microbiota balance, reduce inflammation, and promote brain-derived neurotrophic factor (BDNF) production, improving cognitive function.
This randomized, crossover clinical trial will enroll 24 patients aged 50-65 with T2DM and mild cognitive impairment. Participants will be divided into control and experimental groups, with an 8-week intervention phase followed by a crossover. The experimental group will receive 8g of inulin and L. acidophilus daily, while the control group will receive a placebo. Cognitive assessments (MMSE, MoCA), PET-CT imaging, gut microbiota sequencing, and butyrate measurements will evaluate the intervention's effects.
The study aims to determine whether symbiotic supplementation can improve cognitive function and metabolic brain activity in T2DM patients. If successful, it may offer an accessible, non-pharmacological approach to mitigating diabetes-related cognitive decline. The research is funded by the Universidad Anáhuac Health Sciences Research Center and international diabetes research organizations.

Trial outcomes
Primary outcomes
Cognitive Impairment
Change in Score in the Folstein Mini Mental Examination, with a higher score (improvement in cognitive impairment) Scoring: 24-30 Uncertain Cognitive Impairment 18-23 Mild to Moderate Cognitive Impairment 0-17 Severe Cognitive Impairment 0 being the lowest and 30 the highest score obtained
Cognitive Impairment
Higher score in Montreal Cognitive Assessment (MoCA), with a total possible score of 30 points, considering a score of 26 or above normal. With the following ranges: Normal range: 26 and above Mild cognitive impairment (MCI): 18-25 Moderate cognitive impairment: 10-17 Severe cognitive impairment: Below 10
Cognitive Impairment
PET-CT with F18-FDG: To be performed at the conclusion of both stages using F18-FDG as a marker to analyze brain metabolic changes
Secondary outcomes
Stool microbiome
Stool Microbiota Sequencing: Assessment of gut microbiota composition at the end of both stages
Stool butyrate
Butyrate Measurement: Determination of butyrate levels in fecal samples to correlate with cognitive and metabolic outcomes.
