When we think about staying healthy as we age, most of us focus on our heart, weight, blood pressure, or fitness levels. But there is another vital organ that deserves just as much attention—our brain.

Brain health is becoming an increasingly important topic for Australians, particularly those aged 30 to 65. While occasional forgetfulness is a normal part of life, maintaining good brain health throughout midlife and beyond can help support memory, concentration, decision-making, emotional wellbeing, and independence as we age.

The encouraging news is that many of the factors that support brain health are the same habits that protect our heart and overall wellbeing. In fact, prevention starts long before symptoms appear.

The Heart–Brain Connection

Many Australians don’t realise that heart health and brain health are closely linked.

Our brains rely on a healthy network of blood vessels to deliver oxygen and nutrients. Conditions that affect the heart and blood vessels can also affect the brain.

Risk factors such as:

• High blood pressure
• High cholesterol
• Diabetes
• Smoking
• Obesity
• Physical inactivity
• Excess alcohol consumption

can increase the risk of cardiovascular disease, stroke, and cognitive decline later in life.

This means that looking after your cardiovascular health today may help protect your brain tomorrow.

Why Prevention Matters

One of the biggest challenges with many chronic health conditions is that they often develop silently over many years.

High blood pressure, elevated cholesterol, diabetes, and early vascular disease frequently have no obvious symptoms. By the time symptoms appear, significant damage may already have occurred.

The good news is that many of these risk factors can be identified and managed early through regular preventative health checks.

Research continues to show that maintaining good cardiovascular health, staying physically active, eating a balanced diet, getting adequate sleep, and managing stress can all contribute to better long-term brain health.

The earlier preventative action begins, the greater the potential benefits.

Your GP Plays a Key Role

One of the most important steps Australians can take for their long-term health is to build a strong relationship with their GP.

Regular GP visits provide an opportunity to identify health concerns early and create a personalised prevention plan based on your individual risk factors.

Your GP can assess:

• Blood pressure
• Cholesterol levels
• Blood glucose levels
• Weight and waist circumference
• Sleep quality
• Mental health and stress
• Family history of disease
• Lifestyle factors that may impact health

These assessments help identify potential issues before they become serious health problems.

For many Australians over the age of 45—or over 30 for Aboriginal and Torres Strait Islander peoples—a Heart Health Check is an excellent way to understand cardiovascular risk and discuss strategies for prevention.

Importantly, regular GP visits are also an opportunity to discuss vaccinations, cancer screening, healthy ageing, and other preventative healthcare measures that support both heart and brain health.

Don’t Ignore Changes in Memory or Concentration

Life can be busy, and many of us occasionally forget names, appointments, or where we left our keys.

However, ongoing changes in memory, concentration, or thinking shouldn’t be ignored.

Speak with your GP if you notice:

• Persistent forgetfulness
• Difficulty concentrating
• Trouble finding words
• Increased confusion
• Changes in mood or behaviour
• Difficulty performing familiar tasks

These symptoms do not necessarily indicate a serious condition. Factors such as stress, poor sleep, anxiety, depression, medication side effects, vitamin deficiencies, hormonal changes, and other medical conditions can all affect cognitive function.

A GP assessment can help determine the cause and identify appropriate support if needed.

Sleep: The Overlooked Brain Health Essential

Sleep is one of the most important—and often overlooked—pillars of good health.

During sleep, the brain performs essential maintenance processes that help support memory, learning, concentration, and emotional wellbeing.

Poor sleep has been linked to:

• Increased blood pressure
• Reduced concentration
• Memory difficulties
• Mood changes
• Increased cardiovascular risk

If you regularly experience poor sleep, excessive daytime fatigue, loud snoring, or symptoms of sleep apnoea, it is worth discussing these concerns with your GP.

Improving sleep quality can have significant benefits for both brain and heart health.

Exercise Benefits Your Body and Brain

Regular physical activity remains one of the most effective ways to support healthy ageing.

Exercise can:

• Improve blood flow to the brain
• Lower blood pressure
• Improve cholesterol levels
• Help maintain a healthy weight
• Reduce stress
• Improve sleep quality
• Support mental wellbeing

The good news is that you don’t need to spend hours in the gym.

Walking, swimming, cycling, gardening, dancing, strength training, and other enjoyable activities can all contribute to better health outcomes.

Aim to move regularly throughout the week and choose activities you enjoy and can maintain long-term.

Stay Socially and Mentally Active

Brain health isn’t only about physical health.

Maintaining social connections and keeping your mind engaged may help support cognitive function and emotional wellbeing.

Activities that challenge the brain include:

• Reading
• Learning a new skill
• Puzzles and games
• Volunteering
• Joining community groups
• Spending time with family and friends

Staying socially connected is particularly important as we age and can contribute to better overall health and wellbeing.

Vaccinations Are Part of Preventative Healthcare

When people think about prevention, they often focus on diet and exercise. However, vaccinations are another important part of maintaining good health as we age.

One vaccine that is often overlooked is the shingles vaccine.

Shingles is caused by the reactivation of the chickenpox virus and can result in a painful rash, long-lasting nerve pain known as post-herpetic neuralgia, and other complications that may significantly affect quality of life.

In Australia, the shingles vaccine is recommended for adults aged 50 years and over.

Under the National Immunisation Program, the vaccine is available free for eligible Australians aged 65 years and over.

Importantly, Aboriginal and Torres Strait Islander peoples are eligible for a free shingles vaccination from 50 years of age through the National Immunisation Program. This recommendation recognises the higher burden of disease and supports better preventative healthcare outcomes for First Nations communities.

If you are aged 50 years or older, speak with your GP about whether the shingles vaccine is appropriate for you.

Your GP can also review your broader vaccination schedule and discuss other recommended vaccinations based on your age, health conditions, occupation, and lifestyle.

Small Steps Today Can Make a Big Difference Tomorrow

There is no single action that guarantees lifelong brain health. However, there is growing evidence that many risk factors associated with cardiovascular disease, stroke, and cognitive decline can be reduced through healthy lifestyle choices and regular preventative healthcare.

Looking after your brain starts with looking after your overall health.

Regular GP visits, preventative health checks, staying physically active, managing blood pressure and cholesterol, prioritising sleep, maintaining social connections, and keeping vaccinations up to date are all practical steps that can support healthy ageing.

Your brain works hard for you every day. Taking simple preventative steps now may help protect your health, independence, and quality of life for years to come.
