Welcoming in a new year is an opportunity to reflect on what areas of our life we wish to change. As we welcome in 2026 could this be the year you decide to prioritise your brain health and what changes you can make to reduce or delay your risk of developing dementia in future.
In this blog we want to help you think about what changes you might want to make to boost your brain health. Each month, we’ll be exploring an evidence-based risk factor for dementia and sharing practical ways you can protect your brain. This month, we’re focusing on one of the 14 modifiable risk factors: physical activity.
Exercise or physical activity is one of those 14 modifiable risk factors. In 2019 the UK Chief Medical Officers’ (CMOs) physical activity guidelines stated a clear message about physical activity:
“If physical activity were a drug, we would refer to it as a miracle cure, due to the great many illnesses it can prevent and help treat.”
Research shows that regular physical activity may reduce your risk of dementia by up to 20% compared to people who don’t take regular exercise. Current guidelines recommend 150 minutes of moderate exercise a week (such as brisk walking or cycling) or 75 minutes of vigorous intensity exercise per week (such as running).
Yet many of us aren’t moving enough. Around 1 in 3 men and 42% of women fall short of these guidelines. Our population is around 20% less active than in the 1960s. If current trends continue, it will be 35% less active by 2030. By aiming for an ‘active lifestyle’ such as actively travelling, through walking/ cycling rather than driving we can hopefully reduce this trend as well as implementing other changes.
People can be put off exercising feeling that they don’t fit a certain stereotype, or that they are not completing enough exercise to be of benefit. However, evidence shows that the people who will achieve the greatest benefit to their brain health are those who go from being inactive to doing some amount of exercise. Sustaining physical activity throughout midlife also seems to have the best effect on reducing dementia risk.
Exercise at any age appears to be helpful for cognition, possibly through changes in blood flow and function from reduced blood pressure, improving brain plasticity or reducing neuroinflammation. Research has shown that people who engage in moderate to vigorous exercise on more days have relatively larger brain volumes than those who do less or no exercise.
Some people may ask what does physical activity mean and to reassure, it doesn’t mean you have to pay for a gym membership or take up running a half marathon to get the benefits. Public Health England break it down into three areas
- Cardiovascular activity
- Strengthening exercise
- Reducing sedentary time
There is little evidence so far of any type of exercise being better than another, meaning that whatever you enjoy, or have fancied trying, whether it is yoga, or walking more, both are likely to be of benefit.
If you’re looking for support to get started, there are plenty of helpful resources available. The NHS Get Active pages offer beginner friendly guidance, and community initiatives like parkrun provide a free, friendly way to get moving. If you’re local to Bath, you might also explore BathFitFam, a welcoming group supporting people of all abilities to take up running.
Small steps can make a big difference. So as you look ahead to the year to come, could 2026 be the year you start moving for your mind?

How vision loss may contribute to dementia
When was the last time you attended for an eye test? Was it due to having symptoms you were concerned about, or for a routine check-up? Would your attendance for eye checks alter if you knew that untreated vision loss is now thought to be a potentially modifiable risk factor for dementia? This month we explore untreated vision loss as a potentially modifiable risk factor for dementia.
Why early diagnosis of dementia matters more than ever
Many people delay seeking help when memory problems begin. They may think it is stress, ageing, or “just one of those things.” Families often notice changes too, but hesitate to raise concerns. Yet when it comes to dementia, early diagnosis can make a life-changing difference. It can provide answers, access to treatment, support for families, and the opportunity to plan for the future with confidence. During Dementia Action Week and beyond, one message remains clear – don’t ignore the signs.
What is dementia: understanding the signs, types and support available
Dementia is a condition many people are familiar with by name, yet its reality is often misunderstood. Too often, it is seen simply as part of growing older, when in fact it is a complex and progressive condition that affects memory, thinking, communication, and the ability to manage everyday life.
In the UK, nearly 1 million people are living with dementia, and that number is expected to rise significantly in the coming years. Understanding dementia is the first step toward creating better awareness, earlier diagnosis, and stronger support for those affected.
