- Atherosclerosis—a build-up of fatty substances along the inner lining of the artery that gradually decrease the area the blood can flow through
- A blood clot that has traveled from other parts of the body such as the neck or heart
- Inflammation of the blood vessels
- Sex: Men are more likely to have strokes than women, but women are more likely to die of strokes than men
- Age: Older than 55 years of age
- Family history of stroke
- High blood pressure
- High blood homocysteine level
- High cholesterol levels—specifically high-LDL bad cholesterol
- Diabetes mellitus or impaired glucose tolerance
- Atrial fibrillation
- Blood disorders such as sickle cell disease and polycythemia
- Disease of heart valves, such as mitral stenosis
- Prior stroke or cardiovascular disease, such as heart attack
- Peripheral artery disease
- Transient ischemic attack (TIA) —a warning stroke with stroke-like symptoms that go away shortly after they appear
- Conditions that increase your risk of blood clots such as:
- Certain autoimmune diseases
- Weakness or numbness of face, arm, or leg, especially on one side of the body
- Trouble speaking or understanding
- Trouble seeing in one or both eyes
- Lightheadedness, trouble walking, loss of balance, or coordination
- Severe headache with no known cause
- Reduce the chance of later strokes
- Improve function affected by the stroke
- Overcome disabilities
- Oxygen therapy
- Precautions to prevent choking
- Decrease blood pressure
- Correct irregular heart rhythms
- Extracranial/intracranial bypass—blood vessel from the scalp is used to reroute blood supply around the blocked artery
- Embolectomy—a catheter is threaded through blood vessels to the clot. It can remove the clot or deliver clot-dissolving medication directly to the area
- 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 improve mood and decrease depression
