Brain Disease-Modifying Effects of Radiofrequency as a Non-Contact Neuronal Stimulation Technology

Abstract

Brain Disease-Modifying Effects of Radiofrequency as a Non-Contact Neuronal Stimulation Technology Sun S, Bok J, Jang Y, Seo H. Brain Disease-Modifying Effects of Radiofrequency as a Non-Contact Neuronal Stimulation Technology. International Journal of Molecular Sciences. 2025; 26(5):2268. doi.org Abstract Non-invasive, non-contact, and painless methods of electrical stimulation to enhance neural function have been widely studied in recent years, particularly in the context of neurodegenerative diseases such as Alzheimer’s disease (AD) and related dementias, which cause cognitive decline and other neurological symptoms. Radiofrequency (RF), which is a rate of oscillation in the range of 3 kHz to 300 GHz (3 THz), has been suggested as one potential non-contact neuronal stimulation (NCNS) technique for improving brain function. A new type of electrical stimulation uses a radiofrequency electromagnetic field (RF- EMF). RF exposure has been shown to modulate neural stimulation and influence various brain activities in in vitro and in vivo models. Recent studies have explored the effects of RF-EMF on human physiology, particularly in areas such as brain activity, cognition, and sleep behavior. In this review, we summarize recent findings about the effects of non-contact stimulations in in vitro studies, in vivo animal models, and human clinical cases. Open access paper: mdpi.com
