畫鐘測驗 (CLOCK DRAWING TEST, aka CDT)
CDT is a simple method to detect whether you may be suffering from memory loss. Ask your loved one to draw a clock, point the hands to "10 after 11," and voila -- you are done! It is one of the ways to screen for dementia. Even if you have depression on top dementia, this simple test can still be useful (http://www.ncbi.nlm.nih.gov/pubmed/15533989)
畫鐘測驗是一個簡單的方法來檢測您是否患有記憶力減退。請你畫一個時鐘，指向 11:10. 畫鐘測驗也適用於同時患有抑鬱和腦退化患者.
If your clocks look like the above, please seek help immediately.
