Far-Infrared Therapy for the Effect of Alzheimer Disease Dementia

Brief Summary

Alzheimer's disease (AD), the most common cause of dementia, is a progressive neurodegenerative disorder characterized by cognitive decline, including impaired learning ability, memory loss, and behavioral disturbances. According to surveys conducted by the Ministry of Health and Welfare in Taiwan, the prevalence of dementia among individuals aged 65 years and older was estimated at 7.86% in 2018, affecting more than 280,000 individuals, and is projected to approach 900,000 by 2065, resulting in substantial medical, social, and economic burdens. Current pharmacological treatments provide only limited symptomatic benefits and may be associated with adverse effects. Therefore, safe and effective non-pharmacological interventions that may support cognitive function and reduce caregiver burden are urgently needed. Experimental studies suggest that far-infrared (FIR) irradiation may enhance mitochondrial oxidative phosphorylation, increase ATP production, and promote microglial amyloid-β clearance, which may help delay the progression of Alzheimer's disease. This trial aims to investigate the safety and effects of far-infrared (FIR) therapy on cognitive function in patients with Alzheimer's disease. The findings may support the clinical application of FIR therapy as a non-pharmacological intervention to improve cognitive function and quality of life, reduce medication burden and treatment-related side effects, lessen caregiver burden, delay institutionalization, and reduce the social and economic burden associated with Alzheimer's disease.
