Investigation of combined treatment of acupuncture and neurofeedback for improving cognitive function in mild neurocognitive disorder

Abstract

Background: Mild neurocognitive disorder (MND) is an intermediate state that can progress to dementia, and the cognitive reserve of MND is an important task in preventing dementia. Acupuncture and neurofeedback (NF) training have been used to improve cognitive function and treat MND or dementia, but their effectiveness remains controversial. In this trial, we will evaluate the efficacy and safety of combined NF-acupuncture treatment in comparison with single acupuncture treatment. Methods and design: This study is a randomized, assessor-blind, pilot trial. It is designed in accordance with the Standards for Reporting Interventions in Controlled Trials of Acupuncture. A total of 44 MND participants who meet the inclusion and exclusion criteria will be enrolled, and each will be randomly assigned to 1 of 2 groups of 22 subjects. Each subject will visit 24 times over 12 weeks and receive either acupuncture or NF-acupuncture combined treatment. At visit 25 (week 13), a follow-up evaluation will be performed, and then the investigator will analyze the results. The primary outcome is defined by the Korean version of the Montreal Cognitive Assessment score from screening to visit 25. The secondary outcome includes the following: change in Alzheimer Disease Assessment Scale–Cognitive, the Korean version of the Beck Depression Inventory, Body Awareness Questionnaire, delayed matching to sample task scores, and functional near-infrared spectroscopy values, from visit 1 to visit 25; heart rate variability values from visit 1 to visit 5, visit 9, visit 13, visit 21, visit 25; breath per minute values from visit 1 to visit 1 to 25. Discussion: We will evaluate the effectiveness and safety of combined NF-acupuncture therapy, and expect that it will serve as the basis for the use of NF together with acupuncture in the clinical setting.

Applications of functional near-infrared spectroscopy in non-drug therapy of traditional Chinese medicine: a review

“…The underlying basis of cognition depends on the proper functioning of brain regions closely linked to the neural network in each brain region. Therefore, fNIRS reveals the therapeutic mechanism of TCM in treating patients with cognitive impairment by detecting changes in the HbO 2 concentration in the cerebral cortex of patients with cognitive impairment ( Eun-Sun et al, 2018 ; Ghafoor et al, 2019 ; Chen J. et al, 2020 ; Jeong et al, 2021 ; Khan et al, 2022 ). Six fNIRS studies were conducted in patients with cognitive impairment, specifically mild cognitive impairment (MCI) and post-stroke cognitive impairment.…”
