Which of the following is a risk factor for brain attack?

• A. Regular exercise
• B. Low-fat diet
• C. Older age
• D. Being a non-smoker

Answer: (C)

Age is a major non-modifiable risk factor for brain attack. As people grow older, blood vessels stiffen and accumulate atherosclerotic changes, and conditions like hypertension and atrial fibrillation become more common. These vascular changes raise the likelihood of an ischemic event from a clot or a hemorrhagic event from a weakened vessel, increasing stroke risk with advancing age.

The other options are protective factors that reduce risk: regular exercise improves cardiovascular health, a low-fat diet helps prevent atherosclerosis, and not smoking lowers vascular risk.
