When patients present with dementia symptoms, doctors don’t always know whether it’s Alzheimer’s, another form of dementia, or something else entirely.

當病人出現認知障礙症狀時，醫生大多未能斷定這是阿玆海默症，另一種認知障礙症，還是其他問題。然而，不同的症狀需要配合不同的治療，因此準確判斷症狀對日後的治療非常重要。目前，利用一種相當先進的正電子掃描(PET Scan)技術，能檢測到腦部形成阿玆海默症的斑塊，讓醫生可以做出更佳的診斷。不過這是否物有所值？
