Understanding Stroke Risk Factors

What is a stroke primarily caused by?

• Excessive brain activity

• Loss of blood supply to the brain

• High sugar levels in the blood

• Increased oxygen levels in the brain

Which of the following is a non-modifiable risk factor for stroke?

• Smoking

• High cholesterol

• Age

• Hypertension

How does hypertension increase the risk of stroke?

• By reducing the heart rate

• By decreasing blood sugar levels

• By increasing the speed of blood cells, leading to vessel damage

• By causing blood vessels to become more flexible

What is hyaline arteriolosclerosis?

• A form of diabetes

• A type of heart disease

• A thickening of small blood vessel walls due to high blood pressure

• A condition where blood vessels become more elastic

Which combination of factors can work together to increase stroke risk?

• Low blood pressure, high oxygen levels, and exercise

• Diabetes, smoking, and high cholesterol

• High fiber diet, regular exercise, and low stress

• Adequate sleep, hydration, and balanced diet

What is atherosclerosis?

• A form of arthritis

• A type of cancer

• A build-up of cholesterol within blood vessel walls

• A condition where blood vessels become more flexible

What heart condition is most strongly linked to an increased risk of stroke?

• Heart murmur

• Atrial fibrillation

• Tachycardia

• Bradycardia

How does atrial fibrillation contribute to stroke risk?

• By increasing blood pressure

• By allowing blood to pool and clot in the atria

• By causing the heart to beat too slowly

• By reducing blood sugar levels

What is a transient ischemic attack (TIA)?

• A form of high blood pressure

• A type of heart attack

• A temporary blockage of blood flow to the brain

• A permanent blockage of blood flow to the brain

What happens if a TIA resolves within 24 hours?

• It is classified as a heart attack

• It is ignored as a health concern

• It is considered a full stroke

• It is termed a mini-stroke
