Natural Approaches to Stroke Prevention

What Is a Stroke?
The third leading cause of death in the United States, a stroke occurs when the blood supply to your brain is suddenly cut off (known as ischemic stroke) or when a blood vessel in your brain bursts (known as hemorrhagic stroke).

As a result of ischemic stroke, brain cells and tissue are deprived of oxygen and nutrients, which causes them to die within several minutes. In hemorrhagic stroke, bleeding causes the brain to swell and press against the skull.

Symptoms of Stroke
Symptoms of stroke include:

sudden numbness, weakness, or paralysis (especially on one side of the body)
trouble with walking (including loss of balance or coordination)
difficulty speaking or understanding speech
sudden blurred or double vision
severe headache accompanied by a stiff neck, vomiting, or facial pain
Who’s at Risk for Stroke?
Risk factors for stroke include:

high blood pressure
high cholesterol
diabetes
obesity
cardiovascular disease
family history of cardiovascular disease
being age 55 or older
cigarette smoking
Treatment for Stroke
In order for stroke to be successfully treated – and for doctors to minimize the potential for severe damage or disability – it’s critical to seek immediate medical attention upon experiencing stroke symptoms.

Treatment of ischemic stroke involves addressing the blood clot causing the problem, while treatment of hemorrhagic stroke involves stopping the bleeding.

How to Prevent Stroke
Following a healthy diet, exercising regularly, managing your stress (with relaxing practices such as yoga or meditation, for instance), keeping your blood pressure and cholesterol in check, and maintaining a healthy weight can help lower your risk of stroke.

These natural substances also show promise as a means of stroke prevention:

1) Tea

For a report published in 2009, researchers reviewed nine studies (including a total of nearly 195,000 people) and found that drinking three cups of black or green tea per day reduced stroke risk by 21 percent. Sipping six or more cups daily may decrease stroke risk by an additional 21 percent, according to the review’s findings.

2) Omega-3 Fatty Acids

In a 2003 study, scientists discovered that eating fish several times per week reduces risk of thrombotic stroke (a type of ischemic stroke that occurs when a blood clot forms in arteries in the neck or brain). An earlier study also found that high consumption of fish and omega-3 fatty acids may be linked to decreased risk of thrombotic stroke.

Abundant in oily fish like salmon and sardines, omega-3 fatty acids are also available insupplement form.

3) Garlic

Although garlic hasn’t been specifically studied for its effects on stroke risk, research suggests that the herb may help prevent blood clotting and buildup of fatty deposits in the arteries, as well as curb high blood pressure.
