Abstract:

Intracerebral hemorrhage (ICH) is a stroke subtype caused by spontaneous rupture of small vessels and bleeding into the brain parenchyma,resulting in cell death and sensorimotor deficits. Despite the greater prevalence of the ischemic form of stroke (87%), ICH has the highest mortality rate of all stroke subtypes. The striatum is the most affected structure in hemorrhagic stroke (35–70%), followed by cerebral cortex (15–30%), brain stem and cerebellum (5–10%); patients suffering striatal and/or cortical ICH bear persistent sensorimotor disabilities. Although chronic sensorimotor impairment is established,a considerable amount of patients experience some degree of spontaneous recovery during the first six months after stroke (Qureshi et al., 2009), and the neurobiological basis of this process is not understood.
