Background: Abnormal glucose metabolism in AD brains correlates with cognitive deficits. The glucose changes are consistent with brain thiamine (vitamin B1) deficiency. In animals, thiamine deficiency causes multiple AD-like changes including memory loss, neuron loss, brain inflammation, enhanced phosphorylation of tau, exaggerated plaque formation and elevated advanced glycation end products (AGE).

Background: Recruitment of demographically diverse participants into Alzheimer's disease (AD) clinical trials, encompassing both screening and randomization, remains a consistent and persistent challenge contributing to underrepresentation of certain groups. Despite the exciting prospects of identifying therapeutic interventions for biomarker-eligible, cognitively unimpaired individuals, these studies grapple with the inherent complexities of AD trials coupled with intricate and time-consuming screening processes. Addressing this the issue of underrepresentation necessitates concerted and intentional efforts that prioritize inclusivity and equitable access to enroll adults meeting study criteria, reflecting the demographic and social diversity of North America.

Given the multifactorial nature of AD, therapeutic strategies need to focus on disease-specific biochemical pathways. Given the significance of metabolic pathways in cognitive impairment, it is essential to investigate alternative disease modifiers capable of targeting multiple metabolic pathways, such as phytochemicals.
