Experts say lifestyle changes can reduce dementia risk and keep your brain young.

Only one in three individuals is aware that specific lifestyle adjustments can significantly reduce the risk of developing dementia, even as public concern regarding the condition continues to rise. Despite widespread anxiety about cognitive decline, experts emphasize that proactive measures remain within reach for the majority of the population.

For those seeking personalized guidance, the Alzheimer's Society offers confidential support through its Dementia Support Line, available by calling 0333 150 3456. Additionally, the organization provides a symptoms checker designed to assist individuals in identifying early warning signs of dementia.

Beyond immediate symptom monitoring, the focus is shifting toward long-term brain health. By engaging in targeted cognitive exercises, individuals can effectively train their brains to function at the level of someone 18 years younger. This approach not only helps determine one's real brain age but also serves as a potent strategy to combat the onset of dementia.

A recent survey reveals a troubling disconnect in the British public's understanding of dementia: while the disease is the nation's leading cause of death, killing 76,000 people annually, only one in three adults recognizes that their risk can be significantly reduced. The data, gathered by OnePoll on behalf of The Daily Mail and the Alzheimer's Society, indicates that 59 per cent of adults experience stress regarding a potential diagnosis, and 43 per cent frequently search for symptoms. This anxiety is often triggered by minor memory lapses, such as forgetting keys or names, which affects one in five people.

The heightened concern over brain health may be linked to the pandemic, with 56 per cent of respondents stating that the crisis made them more health-conscious. Furthermore, personal experience plays a role, as half of the 2,000 adults surveyed know someone living with dementia or caring for one. Despite these realities, public knowledge remains surprisingly low; only 11 per cent correctly identified dementia as the UK's biggest killer, while 41 per cent mistakenly believed it was cancer.

The partnership between The Daily Mail and the Alzheimer's Society aims to bridge this knowledge gap through their Defeating Dementia campaign. The initiative seeks to improve early diagnosis, accelerate research, and enhance care standards. Michelle Dyson, chief executive of the Alzheimer's Society, emphasized that the findings highlight an urgent need for better public education. "The findings underscore the need for greater public education about dementia and the practical steps people can take to reduce their risk," she stated.

Projections suggest that dementia cases will surpass one million by 2030, with one in three people born today expected to develop the condition in their lifetime. However, research indicates that nearly half of these cases could be prevented or delayed by addressing 14 specific risk factors. Currently, only 32 per cent of the public believes this is achievable. While many are aware of common risks like traumatic brain injury, excessive alcohol use, social isolation, smoking, inactivity, and depression, fewer people recognize other critical factors.

These less commonly known risks include poor educational attainment in early life, uncorrected vision or hearing loss, air pollution, high cholesterol, diabetes, obesity, and high blood pressure. Conversely, misconceptions persist regarding causes such as lack of sleep, chemical exposure, vitamin deficiencies, dehydration, aluminium, and poor dental hygiene. Dyson noted that research shows everyday choices genuinely matter. "Regular exercise, avoiding smoking, tackling hearing loss and managing long term conditions such as high blood pressure and diabetes all play a meaningful role," she added, concluding that a holistic approach to overall health remains the most effective strategy for supporting brain health as we age.

Beyond health, the survey exposed significant concerns regarding financial preparedness. Fifty per cent of respondents expressed a desire to know in advance if they were destined to develop dementia, primarily to spend more time with loved ones, plan care and finances, improve their health, document memories, or travel. However, a stark gap exists between public expectation and reality regarding costs. Most people estimate annual care costs at around £20,000, yet severe cases average £81,000 per year, and even mild cases average £29,000.

Consequently, 49 per cent of those surveyed admitted they have no financial plan for future care expenses. A quarter intend to rely on income, savings, and pensions, while 11 per cent would need to sell their home. Very few have insurance coverage, with only 7 per cent relying on an insurance payout and 10 per cent holding a critical illness policy. Peter Hamilton, head of market engagement at Zurich UK, which commissioned the poll, warned against the fatalistic view that dementia is inevitable. "Too many people still believe dementia is an inevitable part of aging, which it isn't," Hamilton said. "By improving understanding and encouraging earlier action both in terms of looking after health and finances, people can feel more in control of their future.
