Hemorrhagic Stroke

Hemorrhagic Stroke

      Hemorrhagic stroke is a stroke caused by non-traumatic intracranial hemorrhage. In a hemorrhagic stroke, blood vessel rupture thereby inhibiting normal blood flow and blood seeping into an area in the brain and damage. Nearly 70% of cases of hemorrhagic stroke in patients with hypertension. Hemorrhagic strokes include bleeding in the brain (intracerebral hemorrhage) and bleeding between the inner and outer layers of tissue that protects the brain (subarachnoid hemorrhage). Other disorders which include bleeding within the skull, including epidural and subdural hematoma, which is usually caused by a head injury.

Clinical Symptoms of Ischemic Stroke

        Clinical symptoms of ischemic stroke can occur at different locations depending on the neuroanatomical and vascularization were attacked, among others:

1. Anterior cerebral artery
         Anterior cerebral artery is an artery that provides blood supply to an area of the cerebral cortex parasagital, which includes motor and sensory cortex area for the contralateral limb, is also the center of inhibitoris bladder (micturition center). 

Ischemic Stroke

Ischemic Stroke

       Stroke Ischemic stroke is also called obstruction, or myocardial stroke, because of the events leading to decreased blood flow or even stop at a particular area of the brain, such as the occurrence of embolism or thrombosis. The decrease in blood flow causes the neurons stop functioning. Blood flow is less than 18 ml/100 mg / min will result in neurons that are irreversible ischemia. Most of the patients or 83% had this type of stroke.
