What activity is thought to decrease the risk of developing dementia?

1. Participating in physical exercise

2. Keeping mentally active throughout one's life

3. Engaging in social gatherings

4. Consuming a balanced diet

The correct answer is: Keeping mentally active throughout one's life

Keeping mentally active throughout one's life is considered a protective factor against the development of dementia. Engaging in mentally stimulating activities—such as reading, playing games, learning new skills, or even practicing problem-solving techniques—helps to build cognitive reserve. This cognitive reserve can make the brain more resilient to damage and potentially delay the onset of dementia symptoms. Lifelong learning and mental engagement stimulate the brain, creating new neural connections and strengthening existing ones, which can help maintain cognitive functions as one ages. While physical exercise, social gatherings, and a balanced diet also contribute positively to overall brain health and can reduce risk factors associated with dementia, the direct emphasis on mental activity highlights its crucial role in fostering cognitive resilience. It's the continuous challenge and stimulation provided by intellectually engaging tasks that specifically targets cognitive decline and is essential for maintaining mental acuity into older age.
