Hemorrhagic strokes make up about 13 percent of stroke cases.
It’s caused by a weakened vessel that ruptures and bleeds into the surrounding brain.
The blood accumulates and compresses the surrounding brain tissue.
Types of Hemorrhagic stroke:
Intracerebral hemorrhage :
- The bleeding occurs inside of the brain. This is the most common type of hemorrhagic stroke.
Subarachnoid haemorrhage :
- The bleeding occurs between the brain and the membranes that cover it.
Both types of hemorrhagic stroke have the conventional stroke risk factors.
In addition, the risk factors for intracerebral hemorrhage include:
Hypertension – the most common cause.
Cerebral cavernous malfunctions – when blood vessels do not form correctly in the brain.
Arteriovenous malformations (AVMs) – a genetic condition where blood vessels form incorrectly, leading to an abnormally tangled web.
AVMs typically occur in the brain and spine. If they occur in the brain, the vessels can break, leading to bleeding into the brain. This disorder is rare.
Risk factors for subarachnoid hemorrhage are most often:
- bleeding disorders
- head injury and trauma
- blood-thinning medication
- a bulge in the wall of a blood vessel called a cerebral aneurysm
An aneurysm can increase in size, causing the artery wall to weaken. If an aneurysm bursts, uncontrolled bleeding may occur.
Symptoms of Haemorrhage Stroke
- sudden severe headache
- vision changes
- loss of balance or coordination
- becoming unable to move
- numbness in an arm or leg
- loss of speech or difficulty understanding speech
- confusion or loss of alertness
- nausea and vomiting
- loss of consciousness
Additional symptoms of either type of hemorrhagic stroke include:
- paralysis or numbness in any part of the body
- inability to look at bright light
- stiffness or pain in the neck area
- hand tremors
- frequent fluctuation in the heartbeat and breathing
- difficulty swallowing
In addition to other medical problems, a stroke can cause temporary or permanent disability. This depends on how long blood flow to the brain was interrupted and which part of the brain was affected.
Possible complications include:
Prevention of Hemorrhagic Stroke:
Hemorrhagic strokes can be prevented in some cases. According to the Centers for Disease Control and Prevention (CDC), 1 in 4 strokes each year are recurrent.
Understanding the risk factors and preventive measures are crucial. Those people at higher risk include smokers and those with one or more of the following:
- High blood pressure or
- High cholesterol
- Being overweight
- A family history of stroke
- Heart disease or disorder
Preventive measures include practicing a heart-healthy lifestyle, which includes:
- Avoiding tobacco products
- Staying within a healthy weight
- Making heart-healthy eating choices
- Managing stress properly
- People should always seek medical care as soon as any of the symptoms of a hemorrhagic stroke are suspected.
