How many different types of strokes are there?

# data[].attributes.body
There are 2 main types of strokes: Ischemic stroke and Hemorrhagic stroke

# data[].attributes.body
These types of strokes occur when there is a loss of blood supply to an area of the brain. This type of stroke is the most common, and can cause serious damage to the brain

# data[].attributes.body
These types of strokes occur when a blood vessel ruptures within the brain. This causes bleeding into specialized areas of the brain. Hemorrhagic strokes are associated with worse outcomes, and recognizing early signs is essential

# data[].attributes.body
Anyone can have a stroke, but risk does increase with age. About 34% of all people hospitalized for stroke are younger than 65

# data[].attributes.body
A CT scan (Computed tomography) that uses x-rays to take picture of your brain is performed right after a suspected stroke. These scams can tell

1) If there is bleeding in the brain (hemorrhagic)

OR

2) If the brain has suffered any damage

# data[].attributes.body
In addition to CT scans, MRI machines (Magnetic resonance imaging) can use magnets and radio waves to create a picture of your brain. This does not identify bleeding, but it can show places that the brain has been damaged

Doctors use scans to examine the brain for stroke diagnosis

Other imaging tests include DSA scan (digital subtraction angiography) and PET scans (positron emission tomography) to look for narrowed blood vessels. Doctors may look for tangled blood vessels called arteriovenous malformation (AVM) in the brain

Hypertension is the most common cause of hemorrhagic stroke

High blood pressure

Cigarette smoking or secondhand smoke exposure

High cholesterol

Lifestyle risk factors that may lead to stroke

# data[].attributes.body
Being overweight or obese

Physical inactivity

Heavy or binge drinking

Use of illegal drugs (cocaine and methamphetamine)

# data[].attributes.body
Many strokes can be prevented through healthy lifestyle changes. If you are older than age 55, working with your health care team to control health conditions that raise your risk for stroke can be essential to your health

# data[].attributes.body
Strokes require immediate attention and treatment to prevent further damage. There are different ways to treat the two types of strokes.

Ischemic

Medicine: Tissue Plasminogen Activator - breaks up blood clots to allow blood back to the brain

Procedures: Angioplasty- opens a blood vessel ; Stent is placed to clear pathways ; Mesh is used capture the clot

Hemorrhagic

Medicine: Blood pressure medication - to lower strain on vessels ; Vitamin K - to stop bleeding

Procedures: Aneurysm Clipping - prevents the spread in the brain ; Draining extra brain fluid ; Drilling hole in the skull to alieve pressure

Aftercare: Rehabilitation programs, breathing support, feeding tube, occupational and/or physical therapy
