Aim of the study: The aim of this research was to examine the knowledge level of undergraduate and graduate students of Nursing at the Faculty of Dental Medicine and Healthcare about Alzheimer's disease. Study design: cross-sectional survey Participants and methods: The research was carried out on a sample of 270 respondents from the first, second and third year of undergraduate nursing studies in Osijek, Nova Gradiška and Pregrada, and the first and second year of graduate nursing studies in Osijek, Slavonski Brod and Sveta Nedelja. The data were collected using an anonymous validated questionnaire called the Alzheimer's Disease Knowledge Scale (AKDS). Results: Female respondents show a higher level of knowledge about diagnosing Alzheimer's disease than male respondents. Graduate students show a higher level of knowledge than undergraduate students, the exception being second year undergraduate students who show a higher level of knowledge than the first and third year undergraduate students. The students in Sveta Nedelja and Nova Gradiška show a higher level of knowledge than the students in Osijek. Also, the students who have or know someone with Alzheimer's disease show a higher level of knowledge. The level of students' knowledge increases with a higher self-assessment of their own knowledge about the disease and reverse. Conclusion: The knowledge of Nursing students at the Faculty of Dental Medicine and Healthcare about Alzheimer's disease is mediocre and most students believe that the faculty did not adequately prepare them to work with the people suffering from it. Greater education of students is needed through various workshops, educations and clinical practices, with the fact that they are the people who will provide healthcare to the sick, but also educate caregivers and the population.
