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).

The aggregation of TDP-43, a crucial RNA-binding protein, is a consequence of post-translational modifications (PTMs) that disrupt its normal function. PTMs such as phosphorylation and ubiquitination contribute to the aberrant accumulation of TDP-43 aggregates, leading to neurodegenerative disorders like amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD).

Background: Benfotiamine, a prodrug of thiamine, raises blood levels by 50-100 times to achieve pharmacologic effects. It provides a novel therapeutic direction addressing a well-characterized brain tissue thiamine deficiency and related changes in glucose metabolism in AD. BenfoTeam is a seamless phase 2A-2B "proof of concept" (POC), double-blind, placebo-controlled RCT investigating tolerability, safety, and efficacy of benfotiamine, as a first-in-class small molecule treatment for early AD.

Background: Mobile health applications have the potential to enhance dementia care and promote well-being among older adults living independently. This systematic review aims to synthesise and evaluate the existing evidence on the effectiveness of mobile applications developed to improve or maintain cognitive function among older adults diagnosed with mild cognitive impairment (MCI) and dementia.
Method: A systematic search was conducted across major electronic databases, including PubMed, The Cochrane Library, Embase, and PsycInfo, to identify relevant studies published from 2012 to 2023.

Background: Although cognitive decline is a trait related to aging, some individuals are resilient to the aging process, defined as SuperAgers. Studying the neural underpinnings of SuperAgers may improve the understanding of AD pathology. In this study, our aim was to analyze amyloid and neurodegeneration imaging biomarkers in SuperAgers.
