Five key takeaways from ‘The Age-Proof Brain’

1Quality sleep is crucial for long-term brain health

“…it is not only the number of hours of sleep you get but also how effective those hours are.”

Sleep plays a crucial role in maintaining both physical and mental health, and the quality of sleep matters as much as the quantity. In the chapter ‘Sleep: It’s Not Just the Number of Hours,’ Dr. Milstein emphasises that poor sleep is not just about feeling tired but is linked to various diseases and conditions, including diabetes, heart disease, depression, anxiety, cancer, obesity, Alzheimer’s, and dementia. Sleep difficulties can disrupt our circadian rhythm, which regulates mood, metabolism, energy, and hormone release.

The book explains the sleep cycle, highlighting three stages: light sleep, deep sleep, and REM sleep. It underscores the importance of effective deep sleep, the phase in which the brain detoxifies and the body repairs itself. Insufficient deep sleep can accelerate ageing and contribute to memory and immune system problems. REM sleep, the dreaming phase, is crucial for memory consolidation, as it reinforces new connections and prunes old ones. Small adjustments, like exposure to natural light in the morning, can help return the brain to its natural rhythms and can have a significant impact on sleep quality and overall health.

2To optimise brain function, the right balance of stress is essential

Stress is a complex phenomenon with both positive and negative effects on the brain and body. While excessive stress can have detrimental impacts, some stress can be beneficial. Beneficial stress, manageable and momentary, can motivate and focus the brain, as well as play a role in cleaning up the brain’s waste and toxins. Stress can also help in growing new brain cells in the hippocampus. However, chronic and prolonged stress can lead to health issues such as chronic inflammation, memory problems, mood changes, depression, anxiety, and even dementia due to the release of cortisol. Achieving the right balance of stress for optimal brain and immune system function is essential.

Managing stress and fostering happiness are key to achieving this balance. Meditation and other mindfulness exercises, such as mindful eating, mindful walks, or engaging in a mindful hobby, can train the brain to focus on the present, reduce stress, and improve overall well-being.

3Regular exercise improves brain function and reduces the risk of cognitive disease

Regular exercise has profound benefits for the brain, akin to a miracle drug. Exercise improves heart health, lowers blood pressure, and enhances metabolism, hormone regulation, and neurochemical balance. Additionally, it increases grey matter in the brain, vital for memory. Exercise fosters improved communication between brain cells, leading to better mood, happiness, and cognitive performance. Studies show that exercise can slow memory decline and reduce dementia risk, with even small changes, like taking the stairs instead of escalators, having positive effects. While too much exercise can be counterproductive, around 120 minutes of moderate exercise per week is recommended for optimal brain health. Intense workouts boost neurotransmitters, making them beneficial for mental health, and even walking for just 30 minutes a day can significantly lower dementia risk.

4Social interactions keep the brain healthy and prevent the negative effects of loneliness

Regular social interaction, such as participating in dinner parties or social events, plays a vital role in preserving memory and overall mental and physical health for individuals over fifty-five. Loneliness, which can be as detrimental as smoking or worse than obesity, is linked to an increased risk of heart disease, Alzheimer’s disease, depression, anxiety, high blood pressure, stroke, and premature death. Loneliness also affects decision-making, attention, and cognitive abilities, and accelerates brain ageing. Meaningful relationships can counteract the negative effects of loneliness.

5Your brain is what you feed it with

Diet plays a crucial role in brain health, and a Mediterranean-style diet is often recommended for its benefits. It includes fruits, vegetables, nuts, whole grains, fish, and healthy fats like olive oil, reducing the risk of conditions like Alzheimer’s. Combining elements of the Mediterranean and DASH diets further lowers Alzheimer’s risk. The author cites various studies that prove that specific foods like pears, olive oil, and kale have been linked to decreased risk of cognitive disease. Seafood consumption supports memory, while combining processed meats with starchy carbs may raise dementia risk. Overall, the book encourages readers to adopt a balanced approach to their diet, with a focus on healthy fats, proteins, and fibre-rich foods.

Strengths and weaknesses, according to readers’ reviews


  • Provides an excellent, evidence-based summary of the current science regarding healthy ageing of the brain.

  • Offers lots of tips about minor lifestyle changes that can be made to increase brain health.

  • Well-written, often humorous, and quite accessible to the general reader.


  • The book is more suited for individuals who are less informed about health topics or specifically concerned about dementia, potentially limiting its appeal to those already well-versed in health-related information.

Best quotes from ‘The Age-Proof Brain’

“There is more to sleep than just rest. For one thing, lack of sleep also throws off our circadian rhythm, our internal body clock that orchestrates aspects of health such as mood, metabolism, energy, and hormone release.”
“Those who had four drinks a day had a brain that appeared about ten years older than their chronological age.”
“Negative and positive mood states can influence the immune system, and vice versa. For instance, increased levels of certain types of pro-inflammatory cytokines can increase the risk of mood disorders and depression. On the other side of the coin, positive mood states are typically associated with a balanced immune system – but as the rugby study shows, even so-called negative moods can be good for health at times.”

Final takeaway

‘The Age-Proof Brain’ by Dr. Marc Milstein offers an invaluable guide to understanding and preserving optimal brain health, especially as we age. Dr. Milstein, with his extensive background in biological chemistry and research, provides a wealth of evidence-based insights in an accessible and reader-friendly manner. While it may not appeal to those already well-versed in health topics, it serves as an enlightening read for people new to the topic and interested in maintaining a healthy brain as they age. Whether you are concerned about dementia or simply looking to improve your overall brain health, this book is a valuable addition to your reading list.
