The Effect of Acupuncture Treatment on Cognitive Functions and Brain Networks for Long COVID

Starting soon · Not applicable · Has a placebo group

Conditions studied: Long Covid

In brief

Background of study: Long COVID(LC) is a prevalent sequalae of SARS-CoV-2 infection and can affect multiple organ systems. Cognitive dysfunction is one of the most common symptoms in LC with 22% prevalence. It can persist for years and significantly reduce patients' quality of life. Brain network is the neural basis underlying human cognitive processes. Diffusion tensor imaging (DTI) and functional magnetic resonance imaging(fMRI) research has revealed that alterations of network characteristics were associated with cognitive impairments across attention, memory, executive function and language in LC. Currently, there is no accepted therapy for cognitive impairment in LC. Acupuncture, as a Traditional Chinese Medicine therapy, has potential to improve cognitive deficits for LC. However, research focusing on the impact of acupuncture on cognitive functions in LC is rare. Additionally, no one has evaluated the mechanism of acupuncture improving cognitive functions in LC. Objective of the study: This study aims to assess the effect of acupuncture treatment on cognitive function and explore the central mechanism of acupuncture therapy in improving cognitive function for LC using cognitive assessments, DTI and resting-state fMRI. Study design: A prospective, three-armed, randomized controlled trial with DTI and rs-fMRI. Adults with LC will be randomly assigned to acupuncture, sham acupuncture, or waitlist control group in a 1:1:1 ratio, receiving 8-week intervention or waiting. Cognitive function and topological attributes of brain networks will be examined at baseline and 8th week. Study population: Patients fulfilling World Health Organization (WHO) criteria for LC will be included in this study.
