Neuropsychiatric disorders are a huge cause of global disability. Despite decades of research little progress has been made on effective treatments for many of these disorders. Brain-computer interfacing (BCI) is a method that allows for a close integration between computer interfaces and functional brain activation. It is currently under investigation to work as a neuroprosthetic to restore vision, hearing and muscle movement. Further development of BCI technologies have the potential to alter the approach taken with regard to the treatment of neuropsychiatric disorders, and may greatly improve the quality of life for many individuals suffering from currently untreatable disorders, such as Alzheimer’s disease, Parkinson’s disease or treatment resistant depression. This article will address what criteria are of importance for effective implementation of BCI in the treatment of different neuropsychiatric disorders, and will provide an overview of the different types of brain computer interfaces that are under development. It will conclude with an overview of limitations and future directions of BCI technologies.
