Our brains are the control centre of everything we do; every thought, movement, and emotion begin with our brain. From everyday decision-making, to solving problems, to remembering and regulating our emotions; the brain plays an essential role in our daily lives. As we grow older, maintaining brain health becomes even more crucial, as the state of our brain can influence our quality of life.

Despite its importance, brain health is often overlooked. Conditions like Alzheimer’s disease, Parkinson’s disease, and traumatic brain injuries can have far-reaching effects on individuals and their families. The good news is that by understanding brain health, we can take proactive steps to preserve it. Early detection and preventive measures can not only reduce the risk of serious neurological disorders, but they also help maintain cognitive function as we age.

What affects brain health?

Our brain is extremely resilient, but it is also susceptible to various factors that can impact its function over time.

1. Age

As we age, our brain naturally undergoes changes. Neurons (nerve cells) may lose some of their connections, and therefore, certain areas of the brain may shrink. Some changes are a normal part of aging and are not typically cause for concern. On the other hand, conditions like dementias, which cause progressive cognitive decline, are not a normal part of aging but should be considered when noticing significant cognitive changes.

2. Genetics

Our genetic makeup plays a large role in brain health. If someone in your family has had a neurological disorder, you may be at an increased risk. Genes do not always determine your fate, however understanding your genetic risk can help you take proactive measures. Family history should always be shared with your healthcare provider so they can tailor preventive care accordingly.

3. Lifestyle factors

A healthy lifestyle is one of the most researched ways to protect your brain. A poor diet, lack of exercise, insufficient sleep, and high levels of stress can all take a toll on brain health. On the other hand, regular physical activity, a balanced diet, good sleep hygiene, and stress management can help keep your brain functioning properly. These factors contribute to reduced inflammation, better circulation, and more efficient neural connections.

4. Injuries and trauma

Traumatic brain injuries caused by accidents or repeated head trauma (such as in athletes or those exposed to physical violence) can have lasting effects on brain health. Even a mild concussion can lead to cognitive changes if not properly treated.

What can we do to protect our brains?

The good news is that a lot of what impacts brain health can be within our control. By adopting healthier habits and making conscious lifestyle choices, we can protect our brains and reduce the risk of developing brain-related conditions.

1. Exercise

Physical activity is one of the best ways to keep your brain healthy. Regular exercise increases blood flow to the brain, supports neuroplasticity (i.e. the brain’s ability to reorganise and form new connections), and enhances cognitive function. It has been shown to reduce the risk of cognitive decline and can even improve mood and memory. Aim for at least 150 minutes of moderate aerobic activity (such as walking, cycling, swimming, dancing) per week.

2. Diet

Your brain needs the right fuel to function optimally. Eating a nutrient-dense diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can provide essential vitamins and minerals to support brain health. Omega-3 fatty acids, found in fatty fish like salmon and walnuts, are particularly beneficial for cognitive function. Foods rich in antioxidants, such as berries and leafy greens, can help protect the brain from oxidative stress, which is linked to cognitive decline.

3. Mental Stimulation

One of the first things I tell my clients undergoing cognitive rehabilitation: think of your brain as if it were a muscle. If I wanted to build muscle, I’d need to go to the gym and place that muscle under some level of stress, so it can build itself. The same happens with our brain, we need to

place it under mild stress to build it. It is important that that stress is just right; not too easy, and not too difficult. Just as physical exercise strengthens the body, mental exercise keeps the brain sharp. Engaging in activities that challenge your mind; like reading, doing puzzles, learning new skills, socialising; can improve memory, problem-solving skills, and cognitive agility. Activities that engage multiple senses and encourage brain activity, like learning a new language or instrument, are especially beneficial.

4. Sleep

Sleep plays a crucial role in brain health, particularly in memory consolidation and cognitive function. During sleep, the brain works to repair itself, process information, and clear out toxins that accumulate throughout the day. Aim for 7 to 9 hours of quality sleep each night, by sticking to a consistent sleep schedule, and creating a restful sleep environment.

5. Stress Management

Chronic stress can damage neurons, impair memory, and contribute to anxiety and depression. Many clients I see are concerned about changes they would have noticed, most commonly forgetfulness. Most of these clients would not necessarily have a degenerative process happening, but rather, would be experiencing the repercussions of prolonged stress that would have accumulated along the years. Practices like mindfulness meditation, yoga, and deep breathing exercises have been shown to reduce stress and promote relaxation. If necessary, psychotherapy is available and beneficial in addressing past and present issues, addressing underlying thought patterns, providing coping strategies and emotional regulation.

Early detection - catching issues before they become problems

Identifying potential issues with brain health early can make a huge difference in preserving cognitive function and improving outcomes. Early detection allows for timely interventions that can slow or even prevent the progression of certain conditions.

1. Cognitive decline

Many experience mild memory lapses as they age, but there’s a difference between normal age-related forgetfulness, and early signs of cognitive decline. Some red flags to watch out for include:

• Difficulty recalling recent events or conversations

• Struggling to complete tasks that were once easy

• Disorientation, getting lost in familiar places

• Significant changes in personality or behaviour

Many times, these issues may be denied by the individual experiencing them. If a loved one is experiencing these symptoms, it’s important to speak with a healthcare provider as soon as possible.

2. Mental health

Conditions like depression, anxiety, and chronic stress can have a significant impact on brain function. Symptoms such as persistent sadness, trouble concentrating, and feeling overwhelmed are often signs that mental health is affecting cognitive performance. Early intervention with a mental health professional can help prevent more serious cognitive issues down the line.

3. Neuroimaging

Advances in brain imaging, such as MRIs and CT scans, can identify brain changes that are indicative of conditions like Alzheimer’s disease, stroke, or traumatic brain injury. If you are concerned about potentially experiencing a neurological issue, speak to your doctor and they would be able to guide you accordingly.

4. Regular check-ups

Regular visits to a healthcare provider are crucial for early detection. By discussing any concerns about memory, mood, or cognitive function with your doctor, you can receive the necessary evaluations, tests, and guidance to address any issues early on.

Taking action – what to do if you’re concerned about your brain health

If you notice signs of cognitive decline or if you simply want to be proactive about your brain health, the best thing you can do is to take action:

1. Consult a professional

If you’re concerned about your brain health or notice any early symptoms of cognitive decline, it’s essential to consult a healthcare provider.

2. Screenings and assessments

Cognitive screenings are a non-invasive way to assess cognitive functioning, such as memory, attention, thinking, problem-solving abilities, visuospatial functions and language. These

assessments can detect early changes in brain function that might not be noticeable in brain imaging. Early intervention can help slow the progression of many neurological conditions.

3. Reach out

If you’re concerned about your brain health or need advice on screenings, assessments, or prevention, don’t hesitate to reach out. As a neuropsychologist, I’m here to help guide you through the process and provide the information you need to protect your brain health.
