The Changing Mind A Neuroscientist’s Guide to Ageing Well by Daniel Levitin Quotes

1. A reliable way to treat hemispatial neglect is through the use of prismatic glasses that gradually shift the patient’s attention toward the side that is neglected.

2. The Greek physicians Herophilus and Erasistratus discovered the nervous system in 322 BC, placing the seat of thought in the brain. It might be fair to say that they were the first neuroscientists. Previously, Aristotle and others thought the brain’s function was simply to cool the blood, due to it’s many folds and creases.

3. Before traveling east, start advancing your body clock as many days before your trip as the number of time zones you’ll be crossing. Get into sunlight early in the day, or use a sunlight lamp. Once you’re on the plane eastbound, wear eyeshades to cover your eyes two hours or so before sunset in your destination city, to acclimate yourself to the new “dark” time.

4. Curiosity, Openness, Associations (as in sociability), Conscientiousness, and Healthy practices are the five lifestyle choices that have

5. Spend time with people who encourage you to grow, to explore new things, and who take joy in your successes.

6. This is how memory works in the brain—as soon as you retrieve a memory, it becomes editable, just like a text document; it enters a vulnerable state and can get rewritten without your intent, consent, or knowledge. Often, a memory is rewritten by new information that gets colored in during one recollection, and then that new information gets grafted onto and stored with the old, all seamlessly, without your conscious awareness. This process can happen over and over again until the original memory in your brain has been replaced with subsequent interpretations, impressions, and recollections.

7. Fending off Alzheimer’s, he says, involves five key components: a diet rich in vegetables and good fats, oxygenating the blood through moderate exercise, brain training exercises, good sleep hygiene, and a regimen of supplements individually tailored to each person’s own needs, based on blood and genetic testing.

The Changing Mind A Neuroscientist’s Guide to Ageing Well by Daniel Levitin Book Summary

PART ONE: The Continually Developing Brain

This section lays the groundwork for a new approach to aging, emphasizing strengths and compensatory mechanisms rather than losses. It examines how personality, memory, perception, intelligence, emotions, pain, and social interactions function and change as we age.

• Individual Differences and Personality: The sources discuss the Big Five personality model: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Conscientiousness, characterized by being planful, reliable, and industrious, is highlighted as a key predictor of healthy aging and longevity. While genetics plays a role, personalities are also malleable, and positive changes can occur at any age.
• Memory and Your Sense of “You”: The sources address the myth of inevitable memory decline, exploring the different types of memory and how they are affected by aging. Active engagement with information, rather than passive learning, is crucial for memory retention. The sources also explain how memory is stored and retrieved, emphasizing the importance of repetition and association.
• Interlude: A Brief Biography of the Brain: This section traces the development of the brain from gestation through adulthood, highlighting key milestones like neural pruning and the role of experience in shaping neural connections. The sources discuss the concept of neuroplasticity–the brain’s ability to adapt and rewire itself–and how it can be harnessed to compensate for age-related changes.
• Perception: The sources explore how our senses provide information about the world and how perception changes with age. They discuss perceptual completion, the brain’s ability to fill in missing information based on context and prior knowledge. The sources also note that while sensory integration can decline, older adults may become more adept at using multiple senses together.
• Intelligence: The sources challenge the notion that intelligence inevitably declines with age. While processing speed may slow down, other aspects of intelligence, such as practical intelligence and wisdom, may improve. The concept of cognitive reserve is introduced–the idea that individuals with greater intellectual engagement and education may be better able to withstand age-related cognitive decline.
• From Emotions to Motivation: This section examines the science of emotions and motivation, discussing how they change as we age and how we can manage age-related changes in mood and drive. The sources discuss the role of hormones and neurotransmitters in regulating emotions, and how levels of these chemicals can fluctuate with age. Allostasis, the body’s ability to maintain stability in the face of change, is discussed, along with the importance of reducing uncertainty to minimize stress.
• Social Factors: The sources emphasize the crucial role of social connections for well-being throughout life, particularly in later years. Social isolation and loneliness are linked to various health problems, including dementia. The sources suggest that as we age, we may naturally prioritize meaningful relationships. They also stress the importance of maintaining a sense of purpose and agency in later life.

PART TWO: The Choices We Make

This section focuses on specific lifestyle choices that can enhance aging, emphasizing that many aspects of aging are within our control.

• Though specific chapter titles for this section are not provided, the sources indicate this section focuses on actionable changes individuals can make to improve their well-being.
• The importance of circadian rhythms is emphasized, highlighting how these internal clocks regulate various bodily functions, including sleep-wake cycles, hormone release, and cellular repair. Disruptions of circadian rhythms are linked to health problems, including cognitive decline.
• Diet, exercise, and sleep are discussed as key areas where individuals can make choices to support healthy aging.
• The sources advocate for continued movement and exploration to keep the brain active and engaged, suggesting that synaptic plasticity, the brain’s ability to form new connections, can be enhanced through physical activity.

PART THREE: The New Longevity

This section explores the scientific and social implications of increasing lifespans, emphasizing the potential for extended health and vitality.

• Again, specific chapter titles are not provided, but based on the book’s overall focus, this section likely addresses the opportunities and challenges presented by increasing lifespans.
• The sources discuss factors that influence longevity, such as telomere length (the protective caps on the ends of chromosomes) and cellular senescence (the process by which cells stop dividing). They highlight the potential benefits of lifestyle choices like exercise and a healthy diet on telomere length while noting that research in these areas is still ongoing.
• Cognitive enhancement is explored, both through pharmaceutical interventions and lifestyle changes. The sources also note the ethical considerations surrounding these advancements.
• The importance of planning ahead for old age is stressed, including choosing healthcare providers and having conversations about end-of-life care.
• The sources suggest that society needs to shift its perspective on aging, recognizing the value and contributions of older adults. They advocate for fostering intergenerational connections and creating a culture that embraces the wisdom and experience of older individuals.
