Globally, a wide range of mental disorders continues to significantly impact people’s lives, with traditional treatment methods often falling short of providing effective and systematic solutions. Brain-computer interface (BCI) technology, one of the most rapidly advancing fields, offers promising applications across various sectors of human society, including production, healthcare, and media. By combining different BCI technologies, such as EEG monitoring and Deep Brain Stimulation, medical institutions can now offer patients a broader spectrum of effective or potential treatment options. This paper provides a comprehensive review of the current application status of various representative BCI technologies in mental health treatment. It also explores the prospect of constructing an integrated treatment system for mental disorders based on BCI technology, aiming to enhance this paper understanding of BCI applications in mental health care. The study examines how different BCI technologies can be utilized at various stages of disease progression, from early diagnosis to long-term management. Additionally, it discusses the potential of BCI in improving patient outcomes, quality of life, and social integration, while addressing ethical considerations and future research directions in this rapidly evolving field.
