Brain haemorrhages (also spelled as hemorrhages, depending on dialect) are also known as bleeds within the brain, and they can occur in several different areas within the brain tissue. Saccular haemorrhages are also known as berry haemorrhages and they are the most common type of aneurysm that happens within the brain. Cerebral amyloid angiopathy is the formation of proteins within the blood vessel walls located in the brain.
There are several types of brain haemorrhages: the different types can be seen on the picture below. Focal ischaemia can be induced by cerebral haemorrhage, embolism or brain injury, and results in rapid neuronal death in a core region within the immediate territory of the occluded artery. There are several underlying causes which can lead to a brain haemorrhage, and they include hypertension (high blood pressure) and other forms of brain injury.


These haemorrhages tend happen when the blood pressure is elevated for whatever reason, as the high blood pressure makes the blood vessels expand and retract more forcefully than at rest. Symptoms that may arise before the (saccular) aneurysm ruptures include sudden, excruciating headaches and loss of consciousness. These proteins can eventually lead to a bleed in the brain because of the vessels weakening. These tend to be triggered by high blood pressure (hypertension) which eventually leads to small leakages.
This is followed by a more delayed infarct (penumbral region), in which neurons might die many hours after the critical insult. These protein (amyloid) formations tend to be similar to those of Alzheimer’s disease, and can be found in a brain biopsy by using Congo Red stain. The regions in which brain haemorrhaging tends to occur (as a result of high blood pressure) include the cerebellum, pons, thalamus and basal ganglia. If left unchecked, like a balloon, the aneurysm will eventually burst and lead to haemorrhage (to a bleed). The odds of surviving a (first) brain aneurysm are fairly high (from 50-75%) after a period of unconsciousness, but unfortunately the chances of another aneurysm bursting are also quite high and the prognosis after subsequent haemorrhages is worse.


Haemorrhages within the dura in the meninges and with the brain tissue itself tend to exhibit a pattern associated with trauma, however within the subarachnoid mater, it tends to form aneurysms.
For those that survive the first haemorrhage, the brain then undergoes a healing phase through inflammation, which leads to scarring of the meninges. In the picture alongside, you can see the protein accumulated in white lines. The haemorrhaging associated with this disease tend to appear different to that of typical brain haemorrhaging. Eventually, over a period of weeks or months, the haematoma (solid swelling of blood within the tissues) resolves itself through the inflammatory process and there can occasionally be significant improvement.
