Brain bruising. Sectioned gross specimen of a brain showing an area of bruising (black caused by a head injury. A blow to the head can rupture blood vessels in the brain,leading to leakage (haemorrhage). If the blood loss is small there may be no symptoms. A clot can put pressure on adjacent parts of the brain,causing a variety of symptoms depending on the region affected. Typical symptoms can include headaches,seizures and speech difficulties. Larger losses can deprive parts of the brain of blood,and therefore oxygen,which leads to a stroke | |
