Brain Computer Interface in Neurology: The Future of Neurorestoration, the Possibilities and Perils. A Narrative Review

Neurological diseases often leave a devastating effect on the quality of life of patients, and their caregivers. Usually, when people are healthy, communication and movement are taken for granted. Unfortunately when disease or trauma happens a disconnection from these basic aspects of life leaves a person stranded with current options still limited in alleviating these devastating situations. That is where Brain-Computer Interfaces come into play, as a novel way of replacing, and treating neurological diseases and injuries. Using advanced computer technologies direct brain activity can be used to issue commands through a computer or a replacement limb, wheelchair, or exoskeleton. Not only replacement but also neuromodulation and neurorehabilitation by way of BCI provide new ways of treating diseases with functional connectivity issues. More and more research is proving its usability, with awe-inspiring prospects for the future treatment of neurological diseases. But as with any technological novelty thorough discussion, and general informing of both the patients and clinicians is needed so as to prevent future worries and disappointment.
