**Which option is best?**

* **Choose Option 1** if you want a short and sweet description.
* **Choose Option 2 or 3** if you want a slightly more detailed and informative tag description.
* **Choose Option 4** if your content frequently addresses the broader impact of the disease.
* **Choose Option 5** for the most comprehensive and informative approach, providing a clear overview of what the tag encompasses. It also includes the original Chinese for reference.

**Important Considerations:**

* **Keyword Usage:** While these descriptions use “老年癡呆” effectively, consider if you want to include related keywords (like “阿茲海默症” (Alzheimer’s) or “失智症” (dementia)) depending on the specific content you’re tagging.
* **Tone:** Adjust the tone to match your website’s general style.
* **SEO:** Keep in mind that the description helps with SEO by giving search engines context.
* **Clarity:** Make sure the description is clear and understandable to readers.

I recommend copying and pasting the description you choose into the “Description” field of the tag in your WordPress admin panel. Remember to save the changes!
