Can Early Recognition of Neuropsychological Emergencies Change Outcomes?

Abstract

A sudden change in how a person thinks, feels, or behaves is usually read as psychological, yet the same presentations can signal stroke, seizures, autoimmune encephalitis, delirium, and life threatening medication reactions, conditions in which outcome depends on how quickly the true cause is recognized and treated. This narrative review examines neuropsychological emergencies as a problem of recognition and immediate response and asks what the first critical minutes of an acute brain disturbance demand of non specialists, students, family members, and frontline staff, who are often the first to notice them. Synthesizing foundational neuropsychology, clinical guidelines, and literature on delirium, cerebrovascular disease, seizures, autoimmune encephalitis, catatonia, and medication induced emergencies, the review identifies a converging structure: acute disturbances of brain function surface as changes in behaviour because cognition, emotion, and behaviour are the observable output of disrupted neural networks. Recognition therefore depends not on symptom memorization but on a small set of discriminating questions concerning change from baseline, speed of onset, surrounding context, and red flags. The evidence also warrants caution, as early imaging and routine tests can be normal in serious disease, while emergencies presenting primarily through psychiatric symptoms may be particularly vulnerable to delayed recognition. The review concludes with design principles for teaching recognition and safe first response to lay and student audiences, considers the broader role of education and awareness, and identifies priorities for future research.
