How to reduce the odds of silent stroke?

Since diabetes, high cholesterol levels and high blood pressure increase the chances of silent strokes, controlling these and alterations in lifestyle habits are most likely to reduce the risk for a silent stroke and improve overall health.

  • Exercise: Working out for at least 30 minutes five days a week may reduce the chances of having a silent stroke by 40 percent
  • Lower your cholesterol levels: Ensure that your overall cholesterol level is lower than 200 mg/dL and your LDL cholesterol under 100 mg/dL
  • Say no to smoking: Smoking is associated with an elevated risk of heart disease and stroke
  • Avoid diet drinks. Consuming artificially sweetened beverages can raise your risk for both dementia and stroke
  • Eat your color: Consume five or more servings of fruits and vegetables every day
