Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This Effects of Non-Invasive Superficial Craniocervical Lymphatic Drainage (NSCLD) on Memory and Cognitive Function in Adults with Sleep deprivation: A Proof-of-Concept Study aims to investigate the effects of Non-Invasive Superficial Craniocervical Lymphatic Drainage (NSCLD) on memory and cognitive function in adults experiencing sleep deprivation(SD). Given the known impact of SD on cognitive performance, this study seeks to explore whether NSCLD, as a non-invasive intervention, can mitigate the cognitive impairments associated with SD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sleep deprivation (SD) is widespread in modern society, particularly among medical students, residents, and individuals in high-stress occupations. Numerous studies have demonstrated that acute sleep deprivation significantly impairs cognitive processes such as attention, working memory, and executive function. Even short-term cognitive impairment can have serious consequences, including impaired judgment, slowed reaction times, and increased error rates.

Currently, interventions targeting cognitive decline following sleep deprivation are limited. Common strategies primarily include medications (such as caffeine and modafinil) and restorative sleep. However, these methods have limitations in both clinical and real-life settings: on one hand, medications may lead to tolerance and side effects, and on the other hand, restorative sleep often cannot reverse cognitive impairment in the short term. Therefore, developing a safe, convenient, and rapidly effective non-pharmacological intervention is of great significance.

In recent years, the glymphatic system has garnered increasing attention. This system is believed to play a key role in clearing metabolic waste from the brain, regulating sleep structure, and maintaining neurocognitive function. Superficial craniocervical lymphatic drainage (SCLD) has been proposed as a potential mechanism to improve cognitive function by enhancing the flow of cerebrospinal fluid (CSF) and lymph, reducing neuroinflammation, and minimizing the accumulation of metabolic waste.

In June 2025, a study published in Nature provided the first in vivo evidence supporting this hypothesis. Researchers applied non-invasive mechanical stimulation to the superficial lymphatic system on the skin surface of the mouse neck, resulting in a doubling of CSF drainage efficiency to cervical lymph nodes and correction of impaired brain-lymphatic efflux function in aged mice. These findings provide direct mechanistic support for the potential application of non-invasive SCLD intervention in humans.

Therefore, this study aims to establish an acute sleep deprivation model in healthy adults and explore the immediate effects of NSCLD intervention on cognitive function, with the goal of providing preliminary clinical evidence for non-pharmacological intervention strategies related to the brain-lymphatic pathway.
