Abstract

Background: Stroke is defined as an acute neurologic injury that is the result of a disruption in cerebral perfusion due to the blockage or rupture of an artery. Ischemic infarcts represent up to 87% of all strokes, and most commonly present with sudden onset, focal neurologic deficits that are consistent with a vascular etiology. Approximately 30% of patients presenting to the Emergency Department with stroke-like symptoms are unfortunately stroke mimics.

Stroke mimics such as syncope, sepsis, seizure, and migraines can present with stroke-like symptoms and are often indistinguishable from true strokes. The study conducted will serve to provide medical residents and medical students with a clearer understanding of such stroke mimics in the hospital setting.

Methods: The data collected through a retrospective chart review of 100 consecutive patients who were admitted to Valley Baptist Medical Center Harlingen with a provisional diagnosis of stroke. The information will be de-identified to protect the privacy of the patients. All eligible candidates, age 18 years and over, were considered regardless of race or gender.

Results: Our chart review included 85 patients presenting with stroke-like symptoms. Of these, 27 patients (31.8%) were found to be CVA mimics, while 58 patients (68.2%) were ischemic strokes or TIA.

Stroke mimics with the highest frequency in our study were migraines (5 cases, 18.5%), syncope/presyncope (2 cases, 7.4%), sepsis (2 cases, 7.4%), anxiety (2 cases, 7.4%) and conversion disorder (2 cases, 7.4%).

Conclusion: Stroke mimics can present with stroke-like symptoms and are often indistinguishable from true strokes. Failure to recognize an acute stroke can delay time-sensitive treatments such as tPA and mechanical thrombectomy and is associated with negative outcomes. In our study, over 30% of suspected strokes turned out to be stroke mimics. With such a high prevalence, it is important for healthcare teams to acknowledge the most common stroke mimic presentations at their own institutions. Clinicians are therefore tasked with forming a balance between rapidly diagnosing acute stroke, while also maintaining a high index of suspicion for possible stroke mimics. Further research efforts are needed to define criteria that can be utilized in the acute setting for rapid diagnosis of stroke mimics.
