Aim: To determine the knowledge of dementia among students and to identify their suggestions on to acquire dementia-related knowledge.

Methods: An online cross-sectional study was conducted in order to determine the knowledge of dementia among students of non-medical high schools in Slovenia. The gender comparison of the knowledge and proposals for a way of educating were obtained.

Results: A total of 1128 students (770 girls and 348 boys) aged 14 -19 participated in this study. The results indicated that of 20 claims of dementia, participants were on average able to answer 71.5% correctly (M = 14.30; SD = 2.56), girls better than boy (p<0.05), students with relative with dementia better than others (p<0.05). Proposals for ways of future dementia education did not differ between the sexes (p>0.05). Both, girls and boys in the same percentage indicated future priority learning methods namely: use of the Internet, learning in school lessons and from books and textbooks, learning from medical staff.
