September marks World Alzehimer's Month, offering a timely reminder to reflect on how Alzheimer’s and other types of dementia impact countless lives. It’s also a great moment to think about our own brain health. No matter your age, there are always ways to sharpen your mental wellbeing. Whether you're caring for someone with dementia or simply want to keep your mind in peak condition, Dementia Educator Carole Kerr shares some valuable advice to help you stay mentally active and feel your best.

Stay socially engaged

Connecting with others is one of the most powerful ways to support brain health. Research shows that maintaining social ties can lower the risk of dementia, while isolation may increase it. Whether it’s meeting up with friends, joining a club, or enjoying a coffee catch-up with family, these moments of connection help keep your brain engaged.

Take on something new

While puzzles like crosswords and Sudoku are great, the real brain boost comes from learning new things. Creating fresh neural pathways is key to mental resilience. This could mean starting a new job, mastering a skill, or diving into a hobby. Ever dreamed of speaking another language or playing an instrument? Trying something unfamiliar helps build a “cognitive reserve” – a kind of mental safety net that keeps your brain flexible and strong.

Get moving

Exercise benefits more than just your physical health – it’s fantastic for your brain too. And when you combine movement with social interaction, the effects are even better. Whether it’s a walk with friends, a group bike ride, or gardening together, staying active and connected supports long-term brain function.

Prioritise sleep

A restful night’s sleep does wonders for your brain. During sleep, your brain clears out toxins associated with Alzheimer’s – think of it as a nightly detox. Poor sleep can lead to a buildup of these toxins, affecting memory and thinking. So, make sleep a priority to give your brain the reset it needs.

Eat smart

What you eat has a big impact on brain health. Carole recommends the MIND diet – a blend of the Mediterranean and DASH diets. Focus on fresh produce, whole grains, and healthy fats like olive oil, while cutting back on red meat and processed snacks. Fish rich in omega-3s, like salmon, is especially good for your brain.

Breathe in the benefits

Fresh air matters more than you might think. Air pollution has been linked to a higher risk of dementia, so improving air quality – both indoors and outside – can help protect your brain. Whether it’s a walk in the park or opening windows at home, a breath of fresh air can make a real difference.

Lighten your mental load

Stress and worry are known to increase dementia risk, so finding ways to relax is essential. Enjoying a hobby, volunteering, or simply sharing a laugh with loved ones can lift your spirits and support brain health. Joy acts as a natural brain booster, helping you stay mentally agile.

Manage your physical health

Be proactive with your health by regularly getting your blood pressure and blood sugar levels checked out. Maintaining frequent visits to your doctor will allow any changes to be picked up early.

There’s no magic formula for perfect brain health, but staying connected, adopting healthy habits, and finding joy in everyday moments can go a long way. The best part? It’s never too late to begin. Whether it’s learning something new, enjoying a laugh, or taking a walk with a neighbour, you’re doing something wonderful for your brain – and your overall wellbeing.
