Neurological

Neurological assessment answers three linked questions: where is the dysfunction, how quickly did it develop, and which causes require action before diagnostic certainty? A focal cortical problem may alter language or one side of the body; a brainstem or cerebellar problem may disturb eye movements, speech, swallowing, coordination, or gait; diffuse cerebral dysfunction more often changes attention or consciousness. Tempo then changes urgency. Abrupt focal loss suggests a vascular event until excluded, while a slowly progressive pattern supports a different outpatient differential. The first priority is physiologic stability, not a disease label. Assess airway, breathing, circulation, responsiveness, point-of-care glucose, and seizure activity while establishing the exact onset or last-known-well time. Acute ischemia can leave threatened tissue around an infarct, and hemorrhage can expand; both processes make delay harmful. Hypoglycemia and seizure can resemble stroke, but identifying a possible mimic must not postpone emergency stroke assessment when a new disabling deficit is present. In the community, sudden face weakness, arm weakness, speech difficulty, new unilateral numbness, new visual loss, or sudden severe imbalance requires an immediate call to EMS/9-1-1, even if...
