ClinConnect Summary

This clinical trial is focused on improving how doctors assess the risk of stroke in patients who come to the emergency department with dizziness or vertigo, which are feelings of spinning or losing balance. The researchers are testing a special computer program that uses machine learning to help identify who might be at higher risk for having a stroke based on their symptoms. The goal is to make it easier for healthcare providers to make better decisions for their patients.

To be eligible for this trial, participants must be at least 20 years old and have experienced dizziness or vertigo that lasts for at least one hour but no more than seven days. They should still be feeling these symptoms when they arrive at the emergency department. However, individuals who have had multiple similar episodes in the past, signs of a stroke, or other serious health issues will not be able to participate. If you join the study, you can expect to undergo assessments and tests that will help researchers understand how effective this tool is in predicting stroke risk. This trial is currently not yet recruiting participants, but it aims to enhance patient care for those experiencing dizziness or vertigo in the future.
