Excessive drinking, exposure to air pollution and head injuries all increase dementia risk, experts say in a report revealing that up to 40% of dementia cases worldwide could be delayed or prevented by addressing 12 such lifestyle factors. Around 50 million people around the world live with dementia, including about 850,000 people in the UK. By 2040, it has been estimated there will be more than 1.2 million people living with dementia in England and Wales. There is currently no cure. However, while some risk factors for dementia cannot be changed, for example particular genes or ethnicity, many are down to lifestyle. \u201cDementia is potentially preventable \u2013 you can do things to reduce your risk of dementia, whatever stage of life you are at,\u201d said Gill Livingston, professor of psychiatry of older people at University College London and a co-author of the report. She added such lifestyle changes could reduce the chances of developing dementia in both those with and without a high genetic risk for such conditions.<\/p>\n

The report from the Lancet Commission on dementia prevention, intervention and care builds on previous work revealing that about a third of dementia cases could be prevented by addressing nine lifestyle factors, including midlife hearing loss, depression, less childhood education and smoking. The research weighs up the latest evidence, largely from high-income countries, supporting the addition of a further three risk factors to the list. It suggests that 1% of dementia cases worldwide are attributable to excessive mid-life alcohol intake, 3% to mid-life head injuries and 2% a result of exposure to air pollution in older age \u2013 although they caution that the latter could be an underestimate.<\/p>\n

While some actions can be taken on a personal level to tackle such issues, many require government-led change, Livingston said. The report includes a list of nine recommendations, including improving air quality, and urges policymakers to \u201cbe ambitious about prevention\u201d.<\/p>\n

While Livingston said the 40% figure was optimistic as the 12 risk factors are unlikely to be completely addressed, small steps could make a difference. Research has suggested that the incidence of dementia in Europe and North America has fallen by around 15% per decade for the past 30 years \u2013 likely because of lifestyle changes such as a reduction in smoking \u2013 even though the numbers of people with dementia are rising as people live longer. The impact of lifestyle interventions, the team add, is likely to be greatest among the most deprived individuals and in low- and middle-income countries.<\/p>\n

It is not clear whether all the risk factors are purely a cause rather than an effect of dementia. The report notes: \u201cDepression might be a risk for dementia, but in later life dementia might cause depression.\u201d Fiona Carragher, director of research and influencing at Alzheimer\u2019s Society, which part-funded the work, called for a boost to dementia research, warning that medical research charities are facing a 40% average fall in research funding because of the Covid-19 pandemic.<\/p>\n
