Abstract
Dementia has become a major public health concern globally. With no cure available and strong evidence for modifiable risk factors, it is imperative that the public are knowledgeable about dementia and to reduce their risk. The aim of this study was to measure the knowledge of dementia and its risk factors in the Australian public, as well as the number and type of information sources used. An online survey promoted through various social media platforms was completed by 596 Australian adults aged 18-78 years (59% aged 18-44 years; 78% female). Eighty-eight percent of respondents were able to recognise dementia from a vignette, more so from a moderate than from a mild symptom vignette. Only 19% of respondents had a good understanding of dementia, that is describing impairment in both cognition and function. Ninety-five percent of respondents recognised that genetics and old age contributed to a person getting dementia. However, respondents had poor knowledge of empirically supported modifiable risk factors, with most viewed as likely contributors to dementia at chance levels (50%) or below. Respondents reported using informal information sources more often than formal information sources to learn about dementia. The public appear to be able to recognise the symptoms of dementia but lack understanding of how dementia impacts both a person's cognitive functioning and ability to perform everyday tasks. Furthermore, the public remain largely unaware of empirically supported modifiable risk factors that contribute to the development of dementia. It is imperative that the public are educated on how to access and evaluate dementia-related information sources in order to increase their knowledge and understanding of dementia.
