Read our Stroke research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study, called COPITCH, is looking at patients who have had an intracerebral hemorrhage—a type of stroke caused by bleeding inside the brain. Researchers want to understand what happens when swelling develops around the area of bleeding, and how this swelling affects a patient's recovery and long-term outlook. The study will collect information from brain scans and patient medical records to answer these important questions.
Currently, there are no proven treatments specifically for the swelling that occurs around brain bleeds, even though this swelling may be a key factor in how well patients recover. This research aims to understand the causes and effects of this swelling so that better treatments can be developed in the future.

As a participant, you will be enrolled when you arrive at the stroke unit after your brain hemorrhage. Researchers will collect information from your brain MRI scans and review your medical records to track the swelling around your bleeding and how it changes over time. You may be asked to complete follow-up assessments as part of standard stroke care. The study is primarily observational, meaning doctors will monitor your condition and record data rather than give you a new experimental treatment.
