What are the main causes of a hemorrhagic stroke?
Hemorrhagic stroke most often occurs when a blood vessel in the brain leaks or ruptures, which is known as a hemorrhagic conversion of an ischemic stroke or a bleeding brain tumor. Other causes include severe brain infection, head trauma, certain bleeding disorders, or an aneurysm.
Which of the following are causes of haemorrhagic stroke select all that apply?
Haemorrhagic stroke can be caused by a number of disorders that affect the blood vessels.
- High blood pressure. The main cause of haemorrhagic stroke is high blood pressure (hypertension).
- Vascular malformations.
- Cerebral amyloid angiopathy (CAA)
- Blood-thinning medication.
- Illegal drugs.
What is the life expectancy after a subarachnoid hemorrhage?
Approximately 25% of patients die within 24 hours, with or without medical attention. Hospitalized patients have an average mortality rate of 40% in the first month. About half of affected individuals die in the first 6 months. Rebleeding, a major complication, carries a mortality rate of 51-80%.
How does intracerebral hemorrhage occur?
An intracerebral hemorrhage (ICH) is usually caused by rupture of tiny arteries within the brain tissue (left). As blood collects, a hematoma or blood clot forms causing increased pressure on the brain. An ICH can occur close to the surface or in deep areas of the brain.
What are five 5 signs symptoms that someone may be having a stroke?

What are the two types of haemorrhage?
The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are intracerebral (within the brain) hemorrhage or subarachnoid hemorrhage. A hemorrhagic stroke occurs when a weakened blood vessel ruptures.
What are the long term effects of a subarachnoid hemorrhage?

Does a brain hemorrhage shorten your life?
Conclusions— Patients with perimesencephalic hemorrhage have a normal life expectancy and are not at risk for rebleeding. No restrictions should be imposed on these patients by physicians or health or life insurance companies.
What happens when somebody has an intracerebral hemorrhage?
An intracerebral brain hemorrhage (ICH) is bleeding in the brain caused by the rupture of a damaged blood vessel in the head. As the amount of blood increases, the build-up of pressure can lead to brain damage, unconsciousness or even death. ICH affects people of all ages.
What part of the brain is damaged by a hemorrhage?
Intracerebral hemorrhage: This bleeding occurs in the lobes, pons and cerebellum of the brain (bleeding anywhere within the brain tissue itself including the brainstem).
What is a silent stroke?
A silent stroke refers to a stroke that doesn’t cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
