Alzheimer's Disease (AD) is the most common cause of dementia, is a growing global health problem for individuals and society. Research indicates that YouTube and similar channels have an important place in people's health-related information exchange. For the research, " Alzheimer Hastalığı" for Turkish videos and "Alzheimer's Disease" for English videos were analysed on the YouTube page. A total of 120 videos were evaluated. The upload date and duration of the video, the number of views, the number of likes and dislikes, the number of uploaders and comments were recorded. The quality and content of the video was assessed using the Video Power Index (VPI), modified DISCERN scale, and Global Quality Scale (GQS). In the scales in which we compared the quality of the videos, it was found that the VPI (p<0.001), GQS (p<0.001) and modified DISCERN scale (p<0.001) scores were significantly higher in the videos published in English compared to the videos published in Turkish. When we compared the sources that published the videos among themselves, we found that there was a significant difference in the GQS (p=0.008) and Modified DISCERN (p=0.023) scores. We think that it would be more beneficial to prepare informative videos about Alzheimer's Disease, which are published in Turkish on the internet, by academic institutions as well as specialist physicians, in a way that meets the expectations of the society and includes the experiences of patients and their relatives.
