Neurological Deterioration and Escalation

Neurological deterioration is a change from a patient's established neurological baseline, not simply an abnormal number. The change may be diffuse, such as falling alertness; focal, such as new aphasia or unilateral weakness; or episodic, such as seizure activity. Each pattern changes the urgency, but a threatened airway always comes first. Use one practical model: establish the baseline, run ABCGS—airway, breathing, circulation, glucose, and seizure activity—repeat the neurological examination, and escalate on the trend or a red flag. Stabilization and diagnostic work-up occur in parallel; waiting to name the lesion can cost time.
