Document Summary
Encephomalacia- a very slow reduction in the brain blood supply which causes an accumulation of small amounts of damage; causes the softening of brain tissue; tends to occur more in the elderly. Blood clots can be dissolved easily and thus are better to have than a plaque of cholesterol. Cerebral haemorrhage means a blood supply inside the brain that bursts; bleeding inside the brain; typically happens in the elderly because blood pressure tends to increases as we mature; sometimes also called a stroke. Subdural hematoma is bleeding between the skull and the outside of the brain, and not into the brain itself; caused by the bursting of blood vessels in the subarachnoid space. If blood vessel bursts inside the brain, it destroys that part of the brain (cerebral haemorrhage) Cerebral haemorrhage is much more dangerous than a subdural hematoma which can be subdued by alleviating pressure.
