Name a non-modifiable risk factor for stroke.

Age is considered a non-modifiable risk factor for stroke because it cannot be changed or influenced by lifestyle adjustments or medical interventions. The risk of stroke increases significantly with age, and this correlation is well-established in medical research. As individuals get older, their blood vessels may experience changes such as increased stiffness and reduced elasticity, which can contribute to a higher likelihood of stroke.

In contrast, the other options presented are modifiable risk factors. High cholesterol levels can be managed through diet, exercise, and medication; obesity can be addressed through lifestyle changes such as weight loss and increased physical activity; and smoking cessation can be pursued to minimize health risks, including those associated with stroke. Understanding the distinction between modifiable and non-modifiable risk factors is crucial for effective stroke prevention strategies and individualized patient care.
