Tackling modifiable risk factors for dementia, such as diabetes and physical inactivity, can reduce the risk of dementia. Especially individuals with a parental family history (PFH) of dementia may benefit from this, since they have more often modifiable risk factors for dementia. Nevertheless, changing health behaviour is difficult. Therefore, we investigated the knowledge, beliefs and attitudes towards dementia (risk reduction) among the general population and among individuals with a PFH of dementia. We found that the knowledge about dementia (risk reduction) is insufficient. Additionally, older individuals perceived dementia as a more severe disease, but perceived less benefits of performing health-enhancing behaviour for their brain health. Young and highly educated individuals perceived less barriers, but had more confidence in their ability to perform the desired behaviour. Perceived benefits and cues-to-action were associated with the intention to change physical activity and alcohol consumption, and perceived barriers were associated with the intention to change diet. Smokers who perceived more barriers to change their smoking behaviour were less likely to have the intention to change this behaviour. Further, we found that individuals with a PFH of dementia feel the need of exchanging experiences of having a parent with dementia, which seemed a prerequisite to thinking about their own health. The Demin study (www.demin.nl) focuses on tackling risk factors for dementia among individuals (40-60) with a PFH of dementia by an online lifestyle programme. In order for dementia risk reduction programmes to be effective, knowledge, beliefs and attitudes towards dementia (risk reduction) should be improved.
