Area of Science:

  • Neurology
  • Emergency Medicine
  • Clinical Diagnostics

Background:

  • Bedside clinical assessment for suspected stroke lacks extensive study.
  • Efficient patient evaluation is vital in emergency departments.
  • Distinguishing stroke from mimics requires refined diagnostic skills.

Purpose of the Study:

  • To determine the frequency and characteristics of stroke mimics.
  • To identify key bedside clinical features differentiating stroke from mimics.

Main Methods:

  • Consecutive suspected stroke presentations were recruited.
  • Standard bedside clinical assessments were performed.
  • Expert panel review, including imaging, determined final diagnoses; analyses identified predictive features.

Main Results:

  • Of 350 presentations, 69% were stroke (241) and 31% were mimics (109).
  • Mimics included 44 'possible stroke or TIA' events.
  • Eight features independently predicted stroke: exact onset time, focal symptoms, vascular findings, neurological signs, lateralization, and clinical subclassification.

Conclusions:

  • Bedside clinical assessment for suspected stroke can be significantly streamlined.
  • Findings have implications for training less experienced clinicians in stroke assessment.
