[Notice] Memory Detective is not a medical device. This test uses AI technology developed and trained in the field of engineering to assess and indicate the potential risk of dementia for the test subject. However, it does not provide any medical diagnosis or judgment. If you believe you need a dementia-related test due to memory decline or other concerns, we recommend visiting a professional institution and consulting with a qualified specialist or expert, regardless of the results of this test. -------------------------------------------------- With advancements in medical science, even dementia, once considered an incurable disease, is showing signs of treatment possibilities. Recently, a drug effective for early-stage dementia was developed and approved by the U.S. FDA, bringing hope to dementia patients and their families. The challenge, however, lies in the fact that the current treatments are effective only for early-stage dementia. * This highlights the critical importance of early diagnosis for dementia. Memory Detective is an app that analyzes users’ voices using AI algorithms. By simply reading a sentence displayed on the app, the AI helps assess the potential risk of dementia. With Memory Detective, you can easily and regularly check your brain health and detect potential dementia early! -------------------------------------------------- About Memory Detective Memory Detective is an AI-based cognitive screening service developed using clinically collected and diagnosed voice data from major university hospitals in Korea. Based on validation using this clinical dataset: ① 85% accuracy in detecting dementia ② 83% accuracy in detecting mild cognitive impairment (MCI)
