Quelle est la cause de cette hémorragie cérébrale ?

In high-income countries, 10 to 15% of strokes are intracerebral hemorrhages (ICH). While ICH incidence has been stable in the last 30 years, the profile of patients have dramatically changed: deep ICH in young people are less frequent but lobar ICH among elderly people is more frequent. The most prevalent underlying vessel diseases are deep perforating vasculopathies and sporadic Aβ cerebral amyloid angiopathy. Despite progress in the understanding of ICH pathophysiology, mortality remains high and functional outcome remains poor. Patients with ICH should - like patients with ischemic strokes - be treated as soon as possible in a stroke unit. The etiological work-up should rapidly disclose the cause of the bleeding, in order to treat - when needed - the possible rare vascular malformation and to tailor secondary preventive strategies to reduce the risk of future recurrent ICH.
