1) Cerebral haemorrhage – it occurs when an artery in the brain ruptures and blood leaks into the brain resulting in parts of the brain lack of blood. Blood irritates brain tissue, causing swelling and pressure, which cause further damage and loss of function.
2) Intracranial haemorrhage (ICH) – when there is bleeding into the brain tissue itself
3) Subarachnoid haemorrhage (SAH) – when blood leaks into the brain surface.
People of all ages can suffer a stroke but 75 percent happen in people over 65. Ischaemic strokes are the most common strokes in older people while younger people are more likely to suffer a haemorrhagic stroke. Most subarachnoid haemorrhages occur in people under 65.
Other common risk factors include:
- being overweight
- excessive alcohol intake
- family history
- heart disease
- heart rhythm disorders e.g. atrial fibrillation
- high blood cholesterol
- high blood pressure
- use of oral contraceptives
Common indicating symptoms of stroke include:
- sudden blurred or loss of vision in one or both eyes
- sudden difficulty in speaking or understanding other people’s talking
- sudden dizziness, loss of balance or difficulty controlling movements
- sudden weakness and/or numbness of face, arm and/or leg especially on one side of the body
We can greatly minimize the opportunity of having a stroke by controlling risk factors as abovementioned. Strokes are usually the result of a combination of factors which have been existing or developing for a long period of time. If a person has two or more known stroke risk factors the opportunity of having a stroke can dramatically increase.

Treating a Hemorrhagic Stroke
A hemorrhagic stroke occurs if an artery in the brain leaks blood or ruptures. The first steps in treating a hemorrhagic stroke are to find the cause of bleeding in the brain and then control it. Unlike ischemic strokes, hemorrhagic strokes aren’t treated with antiplatelet medicines and blood thinners because these medicines can make bleeding worse.
