ABSTRACT
Background: For a favorable outcome, patients admitted to critical care units require continuous monitoring and swift decision-making ability regarding management. One of the biggest challenges in neurocritical care units is the identification and management of autonomic dysfunction and in the worst-case scenario, autonomic storms. Objective: Most of the literature available focuses mainly on autonomic storms following traumatic brain injury. However, due to the myriad neurological presentations in a critical care setting, it is particularly important for physicians and intensivists to suspect and manage autonomic dysfunction in various neurological scenarios. Methods: Understanding the mechanism of paroxysmal sympathetic hyperactivity (PSH) is essential for early recognition and treatment. PSH-AM is an assessment measurement scale to diagnose and assess the severity of PSH in traumatic brain injury. However, this is not yet standardized across all neurological settings. Conclusion: We present a comprehensive report on understanding the mechanism of autonomic storms across various neurological disorders and outline the management.
