Neuroengineering frontiers: bioengineering and technological interventions for brain disorders

Abstract Introduction Brain disorders, including Parkinson’s disease, epilepsy, traumatic brain injury, and psychiatric illnesses, continue to pose substantial clinical and societal burdens. Traditional treatment approaches are often limited by poor targeting efficiency and the complexity of neural networks. Neuroengineering combines principles of engineering, materials science, and neuroscience to develop innovative tools capable of monitoring and modulating brain activity. Advances in neural interfaces, neurostimulation technologies, and bioengineered therapeutic systems are enabling more precise and minimally invasive treatment strategies, offering new possibilities for restoring neurological function and improving patient outcomes. Short summary Brain disorders represent one of the greatest challenges in modern medicine, demanding innovative approaches that integrate neuroscience, engineering, and technology. Neuroengineering has emerged as a transformative discipline that bridges these domains, offering new strategies for diagnosis, monitoring, and therapeutic intervention. This review discusses recent advances in neuroengineering technologies, including neural interfaces, neurostimulation systems, nanotechnology-based therapeutics, and tissue engineering approaches supported by artificial intelligence for precision brain disorder management. Conclusion Neuroengineering represents a rapidly evolving field with the potential to transform brain healthcare through innovative diagnostic and therapeutic technologies. Continued interdisciplinary collaboration and technological refinement are essential to overcome translational challenges and achieve widespread clinical implementation.
