Translation
Which of the following increases the risk of dementia (認知症)? Choose the most appropriate one.
- Physical activity
- Eating unsaturated fatty acids
- A drop in chewing function (咀嚼機能) because of losing teeth
- Using a hearing aid because of hearing loss (難聴)
- Volunteer activity
Show answer and explanation
Answer: 3
Why 3 is correct
When teeth are lost and chewing function (咀嚼機能) drops, there is less stimulation to the brain, and nutrition can become unbalanced. This raises the risk of dementia (認知症). Treating teeth or using dentures so a person can chew again helps prevent this.
Why 1 is wrong
Physical activity, like walking or moving the body, is a factor that lowers the risk of dementia (認知症). It does not increase it.
Why 2 is wrong
Eating unsaturated fatty acids, which are found a lot in fish, is thought to lower the risk, not raise it.
Why 4 is wrong
It is hearing loss (難聴) itself that raises the risk. Using a hearing aid to hear better lowers the risk, because it helps a person keep having conversations with others.
Why 5 is wrong
Social activity, like volunteer work, gives more chances to talk with people, so it lowers the risk of dementia (認知症).
Key point
When chewing ability drops, the risk of dementia (認知症) goes up.

- Chewing food with the teeth.
