Neurocritical care is an interdisciplinary specialty integrating critical care medicine, neurology, and neurosurgery, focused on the comprehensive monitoring and management of patients with acute brain injury. This review summarizes major advances in neurocritical care reported in 2025. Recent progress in the management of ischemic stroke, hemorrhagic stroke, and traumatic brain injury (TBI) has further clarified the roles of endovascular therapy, transfusion strategies, and other targeted interventions in clinical practice. The introduction of MK 4.0 represents a paradigm shift in the understanding and management of intracranial pressure, while the B-ICONIC consensus has provided structured recommendations for the clinical application of noninvasive intracranial pressure monitoring. In addition, the development of a multidimensional assessment framework for TBI, the publication of a consensus statement on acute severe encephalopathy, and the proposal of a six-step roadmap for disorders of consciousness (DoC) have further refined current diagnostic and therapeutic pathways. Collectively, these advances reflect an ongoing transition toward greater standardization, precision, and individualized management in neurocritical care, with important implications for improving outcomes and guiding future research in acute brain injury.
