This is a research study looking at cerebral venous thrombosis (CVT)—a rare but serious condition where blood clots form in the veins of the brain. Researchers are collecting information from hospital records across Norway between 2014 and 2023 to understand who gets this condition, what symptoms they have, how doctors treat it, and how people do in the years afterward.
Cerebral venous thrombosis is uncommon, which means doctors don't have a lot of information about it compared to other conditions. By studying a large group of Norwegian patients over many years, researchers hope to better understand who is at risk, how the condition affects people's lives long-term, and whether current treatments are working well.

If you're in the main study, researchers will review your hospital medical records and link them with information from Norwegian health registries and databases—no visits or extra burden on you. If you're in the newer follow-up part, you may be asked to complete interviews and fill out questionnaires about your quality of life and how the condition has affected you, in addition to the medical record review.
