Overview
This study is to find out the significance of gut-microbiota in acute stroke patients, including their neurological, radiological outcomes as well as their stroke mechanisms.
Description
Patients who suffered from acute stroke and in hospitalization in Prince of Wales Hospital will be recruited in the study.
After the informed consent, their first bowel opening will be collected for storage. They will also receive assessment by the stroke team at 3 and 6 months to determine their outcomes (NIHSS and mRS). Clinically and radiologically parameters including their degree of disability, imaging findings will also be collected to determine whether there are any correlations with the stool microbiota composition against matched individuals.
