What are the causes of Brain Haemorrhage?
• Hemorrhagic stroke – Seen in 30-60% of hospital admissions due to stroke. High blood pressure (BP) increases the risk of bleed in the brain in stroke patients • Head Injury • Rupture of Aneurysm – An aneurysm is a defect in the wall of the artery. As age advances the pressure of the flow blood causes thinning of this wall with an out pouching of the vessel (aneurysm). When the aneurysm ruptures it leads to Brain Haemorrhage. • AVM (Aretrio Venous Malformation) – There is an abnormal connection between the arteries and veins. This is usually a defect from birth. Due to this abnormal connection, the pressure in the arteries is directly transmitted to the veins leading to bleed over a period of time. When the AVM occurs in the brain blood vessels, it leads Brain Hemorrhage. • Brain tumor bleed – Some brain tumors are very vascular and may at times spontaneously bleed.
