Brief Summary:
As populations age, Alzheimer's disease (AD) is increasing while disease-modifying drugs remain elusive, making early diagnosis and intervention essential. Building on advances in neuromodulation and virtual reality (VR), we target amnestic mild cognitive impairment (aMCI)-the prodromal stage of AD-as a key window for prevention. Preliminary evidence shows disrupted theta-delta phase-amplitude coupling in prefrontal and temporal cortices in aMCI, whereas olfactory enrichment can enhance hippocampal synaptic function, improve cognition, and potentially lower AD risk. We will conduct a large-scale clinical cohort study to test the neural mechanisms and clinical efficacy of multi-site, cross-frequency transcranial alternating current stimulation (tACS) combined with multisensory (visual-olfactory-auditory) VR. A comprehensive database spanning demographic, neuropsychological, biochemical, neuroimaging, and neuromodulation parameters will guide optimal protocols and provide objective evidence for non-pharmacological interventions, informing development of a microcurrent brain stimulator and a portable VR device.
Detailed Description:
With the accelerating pace of population aging, the prevalence of Alzheimer's disease (AD) continues to rise, yet effective disease-modifying pharmacotherapies remain unavailable. Early diagnosis and intervention are critical to slowing cognitive decline and reducing disease burden. In recent years, rapid advances in neuromodulation and virtual reality (VR) have opened new avenues for mechanistic studies and functional brain rehabilitation in AD and other neurodegenerative disorders. Amnestic mild cognitive impairment (aMCI) is widely regarded as the prodromal stage of AD and represents a key window for prevention and treatment. Developing innovative non-pharmacological therapies for individuals at this early stage has therefore become an urgent clinical priority. Preliminary studies indicate that people with aMCI exhibit a significant loss of phase-amplitude coupling (PAC) between theta and delta rhythms in the prefrontal cortex and temporal lobe, whereas olfactory-enriched environmental stimulation can enhance hippocampal synaptic function, improve cognition, and lower AD risk. Accordingly, we propose a large-scale clinical cohort study to investigate the neural-circuit mechanisms and clinical efficacy of multi-site, cross-frequency transcranial alternating current stimulation (tACS) and multisensory VR integrating visual, olfactory, and auditory inputs for the treatment of aMCI. We will establish a comprehensive database encompassing demographic, neuropsychological, biochemical, neuroimaging, and neuromodulation parameters. Ultimately, this work will provide optimal theoretical parameters and objective evidence to guide the development of non-pharmacological interventions for AD-specifically, a microcurrent brain stimulator and a portable VR device.
