(Stroke, Right-side; Right Hemisphere Stroke; Stroke, Right Hemisphere)

- A clot that forms in another part of the body (eg, heart or neck) breaking off and blocking the flow in a blood vessel supplying the brain (embolus)
- A clot that forms in an artery that supplies blood to the brain (thrombus)
- A tear in an artery supplying blood to the brain (arterial dissection)
|Hemorrhagic vs. Ischemic Stroke|

Certain conditions, such as:
- High blood pressure
- High cholesterol
- High levels of the amino acid homocysteine (may result in the formation of blood clots)
- Atherosclerosis (narrowing of the arteries due to build-up of plaque)
- Atrial fibrillation (abnormal heart rhythm)
- Metabolic syndrome
- Type 2 diabetes
- Alcohol or drug abuse
- Medicines (eg, long-term use of birth control pills )
- Lifestyle factors (eg, smoking , physical inactivity, diet)
- History of having a stroke, heart attack , or other type of cardiovascular disease
- History of having a transient ischemic attack (TIA)—With a TIA, stroke-like symptoms often resolve within minutes (always in 24 hours). They may signal a very high risk of having a stroke in the future.
- Age: 60 or older
- Family members who have had a stroke
- Gender: males
- Race: Black, Asian, Hispanic
- Blood disorder that increases clotting
- Heart valve disease (eg, mitral stenosis )
- Weakness or numbness of face, arm, or leg, especially on the left side of the body
- Loss of balance, coordination problems
- Vision problems, especially on the left-side of vision in both eyes
- Difficulty swallowing
- Left-sided weakness and/or sensory problems
- Speaking and swallowing
- Vision (eg, inability for the brain to take in information from the left visual field)
- Perception and spatial relations
- Attention span, comprehension, problem solving, judgment
- Interactions with other people
- Activities of daily living (eg, going to the bathroom)
- Mental health (eg, depression , frustration, impulsivity)
- Exam of nervous system
- Computed tomography (CT) scan —a type of x-ray that uses a computer to make pictures of the brain
- CT angiogram—a type of CT scan which evaluates the blood vessels in the brain and/or neck
- Magnetic resonance imaging (MRI) scan —a test that uses magnetic waves to make pictures of the brain
- Magnetic resonance angiography (MRA) scan —a type of MRI scan which evaluates the blood vessels in the brain and/or neck
- Angiogram —a test that uses a catheter (tube) and x-ray machine to assess the heart and its blood supply
- Heart function tests (eg, electrocardiogram , echocardiogram )
- Doppler ultrasound —a test that uses sound waves to examine the blood vessels
- Blood tests
- Tests to check the level of oxygen in the blood
- Kidney function tests
- Tests to evaluate the ability to swallow
- Dissolve a clot causing an ischemic stroke
- Stop the bleeding during a hemorrhagic stroke
- Dissolve clots and prevent new ones from forming
- Thin blood
- Control blood pressure
- Reduce brain swelling
- Treat an irregular heart rate
- Work against any blood-thinning drugs that you may regularly take
- Reduce how your brain reacts to bleeding
- Control blood pressure
- Prevent seizures
- Reroute blood supply around a blocked artery
- Remove the clot or deliver clot-dissolving medicine (embolectomy)
- Remove fatty deposits from a carotid artery (major arteries in the neck that lead to the brain) ( carotid artery endarterectomy )
- Widen carotid artery and add a mesh tube to keep it open ( angioplasty and stenting )
- Remove a piece of the skull ( craniotomy ) to relieve pressure on the brain and remove blood clot
- Place a clip on or a tiny coil in the aneurysm to stop it from bleeding
- Physical therapy—to regain as much movement as possible
- Occupational therapy—to assist in everyday tasks and self-care
- Speech therapy—to improve swallowing and speech challenges
- Psychological therapy—to help adjust to life after the stroke
- Exercise regularly .
- Eat a healthy diet that includes fruit, vegetables, whole grains, and fish.
- Maintain a healthy weight.
- If you drink alcohol , drink only in moderation (1-2 drinks per day).
- If you smoke, quit .
