Intracerebral Hemorrhage (ICH)

Severe brain injuries can leave people in states where they are unconscious or only partly aware, such as a coma. These conditions are common after injuries like head trauma or bleeding in the brain. One of the biggest challenges for doctors is knowing if - or when - a patient will wake up and regain awareness. This research study is being done to determine if patterns in brain activity during sleep (measured by EEG) can help doctors better predict how quickly someone will wake up and recover after a serious brain injury, as well as how well they might do in the long term. It also aims to develop new ways of using EEG to track how the brain's networks heal and reconnect over time.

This study will establish a prospective, multicenter national cohort of patients with spontaneous intracerebral hemorrhage (ICH). A standardized multimodal database integrating clinical, biological, and imaging data will be collected. The study aims to better characterize ICH patient phenotypes, identify diagnostic and prognostic biomarkers, and describe adherence to evidence-based acute management strategies, including the proportion of patients managed according to the care bundle validated in the INTERACT 3 study. The cohort is also intended to provide a structured platform for translational research and the preparation of future stratified interventional clinical trials in spontaneous ICH.

The objective of this observational study is to investigate the predictive value of various imaging signs in patients with intracerebral hemorrhage, thereby providing a reference for clinical diagnosis and treatment. The primary aim is to evaluate the association between specific imaging signs and both hematoma expansion and poor outcomes in these patients.
