* **Audience:** Who are you writing for? General public, healthcare professionals, caregivers?
* **Content Focus:** What is the primary purpose of your blog or website? Education, support, research, or a combination?
* **Length:** WordPress tag descriptions usually have limited space. Choose the one that best fits the available space and your needs.
* **Keywords:** Even in the description, think about keywords people might search for (e.g., 阿茲海默症 – Alzheimer’s disease, 照顧 – caregiving, 症狀 – symptoms). While not a major factor, keywords will slightly improve results for on-site searches.

When adding the description in WordPress, you would typically go to **Posts > Tags**, find the tag “老年痴呆” (or add it if it doesn’t already exist) and then fill in the “Description” field.
