Stroke symptoms require immediate medical attention. The CDC stroke warning-sign guidance says to call 911 right away for sudden weakness or numbness, confusion or trouble speaking, vision difficulty, balance or walking problems, or a sudden severe headache. This page addresses later record review; it is not a tool for deciding whether to seek emergency care.

A stroke review should follow the actual clock, information, decisions, and available options—not an outdated universal treatment window.

Build one synchronized stroke timeline

  • Last known well, first symptom or change, witness observations, 911 call, dispatch, EMS assessment, prearrival notice, arrival, triage, and first clinician evaluation
  • Reported symptoms, prior function, medications, anticoagulant information, vital signs, glucose, neurologic findings, stroke-scale entries, changes, and competing explanations
  • Orders, specimen and result times, brain and vascular imaging, image availability, radiology interpretation, stroke-alert activation, consultations, and transfer communications
  • Treatment considered, stated eligibility or exclusion reasons, consent or refusal, medication or procedure start, transfer departure and arrival, and later changes in diagnosis

Use current clinical guidance without turning it into a verdict

The National Institute of Neurological Disorders and Stroke explains the role of symptom timing, neurologic assessment, brain imaging, and vascular imaging in stroke assessment and treatment. The American Heart Association and American Stroke Association published a 2026 acute ischemic stroke guideline addressing current systems of care, thrombolysis, imaging, transfers, and endovascular treatment.

Guidelines evolve and contain patient-specific eligibility, contraindication, imaging, severity, timing, and system-of-care considerations. The applicable professional standard must be evaluated for the time and circumstances of the event. A missed target time, the absence of one treatment, or a poor outcome is not automatically malpractice.

Separate recognition, decision-making, and system delay

  • Recognition: what symptoms and changes were reported or observed, by whom, and when
  • Assessment: which history, examination, scale, test, image, and differential information was available at each decision point
  • Escalation: when stroke personnel, neurology, radiology, another facility, or an interventional team was contacted and what was communicated
  • Execution: what orders, treatment, monitoring, transport, or transfer actually occurred and what explains each interval

Prove causation separately from delay

A legal review needs more than a longer-than-expected interval. It should identify the stroke type and location, baseline and later deficits, evolving imaging, treatment that was realistically available, patient-specific risks or exclusions, alternative causes of injury, and a qualified opinion about what a timely different response probably would have changed.

G.S. 90-21.12 provides North Carolina's standard-of-care framework. Rule of Evidence 702 governs qualified expert testimony, and Rule 9(j) generally requires qualified prefiling review of the available care and records.

Use the general diagnosis guide for the broader process

The related North Carolina missed-diagnosis guide explains the broader sequence of history, examination, differential assessment, testing, follow-up, standard of care, causation, and qualified review.
