Current Perspective of Brain-Computer Interface Technology on Mild Cognitive Impairment

Abstract

This work find that the current literature review of brain-computer interface (BCI) in the treatment for the people suffering from mild cognitive impairment (MCI) is a relatively unexploited field compared to other application of BCI techniques. Through our literature retrieval strategy, starting from the theoretical basis of BCI in the treatment of MCI and the pathological basis of MCI, this paper explains the advantages and importance of introducing brain-computer interface into the treatment of MCI. Then, starting from the mode of obtaining brain-related information from BCI, the paper describes the detection methods and possible treatment methods of BCI in the field of treating MCI by applying multiple BCI-related methods such as BCI-based EEG method, BCI-based fMRI method, and BCI-based fNIRS method. This paper also discusses how these BCI-based methods can be combined and interact with each other to provide a better detection and treatment for MCI diagnosis and rehabilitation. Finally, the above several forms of BCI are used to describe the possible future development direction and the existing difficulties of these methods, and why these difficulties may prevent researchers from applying these methods to the actual clinical practices.
