Optimization of the Management of Non-Traumatic Intracerebral Hemorrhage (OPT-ICH)

Intracerebral non-traumatic intraparenchymal hemorrhages (ICH) account for 15 to 20% of strokes. One third of the patients dies within the month following ICH, and survivors often experience residual disability with a high risk of recurrent ICH, other serious vascular events, and neurological complications such as epilepsy and dementia. Encouraging but preliminary data suggest a favorable trend in terms of survival rates in recent years. This is partly due to improved management of patients with ICH, which must be early (the concept of "time is brain") and carried out by expert personnel (medical and paramedical) in specialized units. The main objectives of the study are: * To evaluate the management of patients with ICH in the acute phase within the University Hospital of Tours by analyzing the procedures adopted in the various relevant departments (neurovascular units, neurosurgery, medical or neurosurgical intensive care, geriatrics); * To evaluate whether the systematic implementation of a dedicated protocol (see \*) for the management of patients with ICH is associated with a reduction in mortality and disability in the short and long term.
