- The signs and symptoms of a silent stroke are subtle but can cause cumulative damage over time.
- Silent strokes affect less functional areas of the brain that do not support speech or movement.
- Silent strokes increase your risk for stroke in the future.
- What’s good for your heart is also good for reducing the risk for silent strokes.
Approximately 15 million people suffer a stroke each year, and it is the second leading cause of disability in the world. When a person suffers a stroke, part of the brain is deprived of its blood and oxygen supply which often leads to permanent disabilities including paralysis, difficulty understanding language, memory and thought deficiencies, or chronic pain.
Understanding strokesMany people confuse heart attacks and strokes. A stroke is not a condition of the heart; it is an event in the brain that occurs when a blood vessel feeding the brain gets clogged or bursts. When this happens, blood flow to the brain is temporarily cut off. During a stroke, brain cells begin to die resulting in permanent damage. A silent stroke occurs when blood flow is interrupted and destroys cells that do not control vital functions of the brain.
How to recognize a silent strokeWhile traditional strokes can be obvious and sometimes devastating, silent strokes are far more subtle and difficult to recognize. The impact of a silent stroke is smaller and typically affects less functional areas of the brain. Because silent strokes do not affect speech or movement, many people do not realize they’ve suffered one. The cumulative effects of silent strokes may lead to significant memory issues or dementia and increase the likelihood of more serious strokes in the future.
Again, silent strokes do not have easy-to-recognize symptoms. In fact, if you’ve suffered a silent stroke you might never know it unless you undergo a brain scan to confirm whether brain damage has occurred.The symptoms or signs that a silent stroke is occurring are often disregarded as insignificant or attributed to normal aging:
- Impairment of a person’s balance, leading to more falls
- Temporary lack of coordinated muscle movement
- Loss of bladder control causing urine leakage
- Changes in mood and personality
- Loss of cognitive abilities
How to lower the risk factors of a silent strokeCertain lifestyle changes can reduce the risk of stroke by 80 percent or more. The biggest risk factors for silent stroke are uncontrolled diabetes, heart disease, high blood pressure and high cholesterol. Let’s take a look at the most common ways to reduce risk for a silent stroke, improve overall health and protect memory:
Control your blood pressure by maintaining a healthy weight, eating a low-sodium diet, getting regular check-ups and taking medications as directed.
Lower your cholesterol by choosing healthier foods that are high in omega-3 fatty acids, soluble fibers and proteins.
30 minutes of moderate-to-intense exercise five times a week can reduce your risk of silent stroke by approximately 40 percent.
Eat a Mediterranean diet to reduce your risk of heart attack and stroke.
Quit smoking. Smoking more than doubles your risk of a stroke.
The good news is silent strokes can be prevented if we keep our risk factors under control. There is no time like the present to reinvest in your health. So be sure to keep your blood pressure and cholesterol levels in a normal range, eat a heart-healthy diet, get regular exercise, stay socially connected and involved, and get annual physical exams to reduce your risk of silent strokes and other vascular conditions.
