Aetiology of intracerebral haemorrage

Spontaneous non traumatic intracerebral haemorrhage (ICH) is usually caused by many different interacting factors, such as the use of alcohol or fibrinolitic drugs, congenital aneurysm, brain tumors, and blood dyscrasia. Age and hypertension-related small vessel diseases, and cerebral amyloid angiopathy are the most common forms of vascular damage which can lead to ICH. Furthermore, a group of inherited cerebral small vessel diseases linked to ICH have been reported recently and the number of these forms is increasing. The presence of leukoaraiosis, lacunar infarcts and microbleeds has been suggested to indicate a higher risk for cerebral hemorrhage. In recent years, MRI and neuroimaging techniques contributed to the understanding and the diagnosis of this disease.
