The most advanced artificial intelligence tries to simulate but cannot replicate the glorious magnificence of the human brain. Each and every one of us holds within our skulls the most complex structure in the known universe but most of us rarely give it a second thought. We brush our teeth every day but what do we do for our brains. In her talks Sabina Brennan reveals the inner workings of the human brain, the most under-used resource on the planet. Using everyday language she translates complex neuroscience into practical information to keep the brain healthy and harness brain power to navigate challenge, build resilience, maintain mental health and optimise performance.

Our brains are constantly changing and it is our behaviours, our thinking, our experiences and the life choices that we make that shape it. What we do and what we don’t do not only influence how well your brain functions in the here and now but how resilient it will be in the face of challenges including ageing, injury, trauma and disease.

When we invest in brain health we can revitalise and reshape our brains, improving our mental agility and emotional wellbeing, generally making us happier, healthier and more productive. Sabina Brennan’s talks benefit anyone who has a brain, because we use our brain for everything that we do her content is always relevant. Some sample topics are listed here but the scope of topics is as wide as you can imagine.

Brain Health – The Best Investment for Retirement

In addition to caring for soon-to-retire employees, catering for their needs has been shown to have a positive impact on company morale. While retirement can be joyful it can also lead to a lack of mental stimulation and increased social isolation, factors that impact negatively on health and increase risk for dementia. In this talk, aimed at soon-to-retire individuals, Sabina Brennan focuses on boosting brain health to promote healthy aging and reduce dementia risk.

Ageing Well

People are not just living longer they are working longer and in the future many will be working past what we currently deem retirement age. It is vital therefore to ensure that all employees, irrespective of their current chronological age, understand the principles of ageing well. Ageism can be directed at both young and old. Embracing age inclusion makes the workplace better for everyone.

Ageism, which is often overlooked as a form of prejudice, can impact negatively on the health, wellbeing and performance of those affected. In western society where ageing is often perceived as a period of decline it’s easy to lose sight of the fact that older workers bring experience, wisdom and improved business outcomes to the workplace.

In this thought-provoking talk Sabina Brennan questions our notions of ageing while also offering scientific insights into the impact that our attitude to ageing can have on our health, wellbeing, cognitive performance as well as offering tips on how to age well.

Brain Fog in Peri-Menopause and Menopause

Menopausal women are the fastest growing demographic in the workforce. Brain fog is often cited as one of the most frightening and debilitating symptoms of menopause.

In this talk Sabina Brennan talks about the symptoms and causes of brain fog in peri-menopausal and menopausal women to allay their fears about developing dementia. In addition she offers general strategies to manage symptoms and long term tips to beat brain fog.

Stress, Anxiety and the Brain

Stress is one of the leading causes of absenteeism in the workplace. Poorly managed chronic stress impacts negatively on the physical, mental and brain health of employees affecting their behaviour, their relationships, their performance, and their ability to think rationally.

In this talk Sabina Brennan takes a deep dive into the psychological and physiological stress response explaining what happens inside our brains when we become chronically stressed and how this can set the stage for anxiety and depression. Brennan then follows with detailed scientifically supported measures to better manage stress.

Sleep and the Brain: Why Your Brain Needs Sleep, and How to Sleep Well

The W.H.O. has declared a sleep loss epidemic with one in three adults getting less than the amount of sleep required for optimum health. Insufficient or poor quality sleep negatively impacts on physical, mental and brain health.

Poor sleep reduces accuracy, slows physical and cognitive reaction times, contributes to productivity losses and depending on the specific job could put colleagues or clients at risk.

In this talk Sabina Brennan explains how insufficient or poor quality sleep can impair our memory, our ability to learn and to concentrate as well as our ability to find solutions to problems or be creative. Brennan then follows with detailed scientifically supported measures to improve sleep.

Brain Fog
Brain fog is a general term used to describe a collection of symptoms that can have debilitating impact on the quality of life, ability to carry out jobs, and relationships of the individuals affected.

Brain fog has hit the headlines recently in the context of Long COVID. Brain fog is not a new phenomenon, people have been experiencing its often debilitating symptoms since way before the pandemic. It was the plight of these individuals who were suffering in silence, being gaslit or catastrophising that they had dementia, that spurred Sabina Brennan to write the Irish Times No 1 best-selling book ‘Beating Brain Fog’.

This masterclass, based on the book, gives in depth insight into the phenomenon, explaining what it is and detailing the symptoms, causes and contributing factors. In addition, Sabina Brennan will offer symptom-specific strategies to cope with symptoms in the short term, as well as longer-term life-changing routines that can be employed to eliminate brain fog completely.

Brain Health
We all brush our teeth every day but most of us never spare a thought for our brains. Dental health is clearly important because we need our teeth to eat, to speak and to smile, but we need our brains for everything. There isn’t one thing you can do without your brain, so brain health matters.

In this lively, entertaining and practical, masterclass based on her Irish Times No 1 best-selling book ‘100 Days to a Younger Brain’, Sabina Brennan introduces brain basics and key neuroscientific concepts that underpin brain health. In addition, she gives actionable advice on how to keep your brain healthy and offers insights and explanations into how and why they work and what can happen if we don’t pay heed to the health of our brains.
