An observational study in Cerebrovascular Event, Acute Ischemic Stroke and Intracerebral Hemorrhage, sponsored by Fondazione Policlinico Universitario Agostino Gemelli IRCCS. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-05-22.
Sponsored by Fondazione Policlinico Universitario Agostino Gemelli IRCCS · Observational
The overall objective of the study is to prospectively validate the diagnostic accuracy of the Stroke Mimics Score (SMS). This score is calculated using information collected at the time of the patient's arrival in the Emergency Department (triage) and may assist clinicians in distinguishing between:
In addition, the study aims to compare its results with other existing tools and to evaluate its performance across different patient groups.
Specifically, the present research seeks to generate data on the reliability of the SMS tool in providing an accurate diagnosis.
2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.
This study's planned enrollment of 1,000 is above the median of 300 across 771 observational studies indexed under Ischemic Stroke.

The final discharge diagnosis will serve as the gold standard.

age, systolic blood pressure, presence/absence of seizure at onset, presence/absence of headache at onset, presence/absence of confusion at onset, presence/absence of syncope at onset, presence/absence of isolated sensory deficit, presence/absence of motor deficit, history of coronary artery disease, history of prior stroke or (TIA).
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The rate of accuracy of Stroke Mimics Score (SMS)
Diagnostic accuracy of the Stroke Mimics Score (SMS) in discriminating between: 1. cerebrovascular events (CVE), 2. stroke mimics (SM), assessed by: Area Under the Receiver Operating Characteristic Curve (AUROC). The AUROC will be calculated with a 95% confidence interval. An AUROC value significantly higher than 0.70 will be considered indicative of an acceptable discriminative ability of the score.
Time frame: through study completion, about 1 year
Analyses across clinical subgroups
To evaluate sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), score calibration, the performance of the grouped version (SMSg), comparison with FABS and TMS, and analyses across clinical subgroups.

Start is estimated for Jun 2026; primary completion for Dec 2026, 6 months later.
Of 394 non-industry observational studies under Ischemic Stroke, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 140. This study's planned 6 months is below that.
Counting every sponsor, half of 436 studies reached it within 53 months; a quarter within 24 and three quarters within 127.
