When we think about staying healthy, we often focus on our heart, our weight, or our blood pressure. But how often do we think about the health of our brain? Our brain is one of the most vital organs in the body. It allows us to think, remember, make decisions, and live independently.

The brain shapes how we communicate, solve problems, and navigate our daily lives. Yet brain health is something many of us rarely think about until something goes wrong.

One condition that brings brain health into sharp focus is dementia.

Dementia is not a single disease. It describes a group of symptoms caused by diseases that affect the brain. These symptoms often include changes in memory, thinking, and the ability to manage everyday activities.

People may notice difficulty remembering recent events, following conversations, finding the right words, or managing familiar tasks such as cooking, driving, or paying bills.

Over time, these changes can have a profound impact on individuals and the families who support them.

It is also important to remember that occasional forgetfulness is a normal part of ageing. Misplacing your keys, forgetting a name, or walking into a room and momentarily forgetting why you went there happens to everyone. Dementia involves changes that are more persistent and begin to interfere with everyday life.

Dementia itself is caused by different diseases of the brain. The most common of these is Alzheimer’s disease, which is why the two terms are often used interchangeably. While dementia becomes more common as people age, it is not an inevitable part of ageing.

Researchers now understand that Alzheimer’s disease can begin developing in the brain decades before symptoms appear. The memory problems people notice later in life are often the result of changes that started many years earlier.

This helps explain why brain health matters throughout life. The encouraging news is that it is never too early — and never too late — to start looking after your brain. The choices we make at different stages of life can influence how our brain ages, and positive changes later in life can still make a meaningful difference.

Many of the habits that protect our heart also support brain health. Staying physically active, getting good sleep, managing blood pressure, maintaining social connections, and keeping our minds engaged all help strengthen the brain as we age.

Keeping our brain active does not mean doing the same crossword every day. The brain benefits most when we learn something new or challenge ourselves in different ways — whether that means learning a language, picking up a musical instrument, taking a different route home, or simply staying curious and engaged with the world around us.

While there is currently no cure for dementia, there is evidence that steps we take to support our brain health can make a difference. Research suggests that up to 45 per cent of dementia cases worldwide could be delayed or prevented through healthier lifestyles and better management of our health.

These same factors can also support people who are already living with dementia, helping to maintain function and quality of life for as long as possible.

With thousands of families in Bermuda facing the challenges of dementia, understanding how to look after our brain health has never been more important.
