Reversing Alzheimer's

Introduction

Alzheimer's disease has long been considered an inevitable fate for those diagnosed with it. However, in her groundbreaking book "Reversing Alzheimer's," Heather Sandison offers a fresh perspective and renewed hope for those affected by this devastating condition. Drawing from clinical examples and cutting-edge research, Sandison presents a comprehensive approach to brain health that goes beyond traditional pharmaceutical treatments.

This book summary will explore the key ideas presented in "Reversing Alzheimer's," offering practical, actionable steps for anyone concerned about cognitive decline, caregivers, and healthcare providers. Whether you're directly affected by Alzheimer's or simply interested in maintaining optimal brain health, this summary will provide valuable insights into promoting cognitive vitality well into old age.

Understanding Alzheimer's: A New Perspective

For decades, the medical community has focused on reducing beta-amyloid plaques and tau protein tangles in the brain, believing them to be the root cause of Alzheimer's. However, Sandison reveals a surprising fact: nearly everyone, including healthy individuals, has these plaques and tangles to some degree. In fact, only 2 percent of people don't have any at all.

This revelation leads to a crucial understanding: Alzheimer's is a complex disease influenced by multiple factors, including:

1. Environmental toxins
2. Poor nutrition
3. Chronic stress
4. Structural issues like sleep apnea
5. Infections
6. Hormonal imbalances

The good news is that many of these factors are within our control. Research has identified 12 modifiable risk factors that account for about 40 percent of worldwide dementia cases. These include:

• Hearing loss
• Hypertension
• Smoking
• Social isolation

By addressing these factors, we can potentially prevent or delay the onset of Alzheimer's. Sandison emphasizes that a good diet, regular exercise, social connection, and general self-care can have profound effects on our brain health.

A Multifaceted Approach to Brain Health

Instead of relying on a single drug, Sandison advocates for a comprehensive protocol that addresses all aspects of brain health. This multifaceted approach includes:

1. Dietary changes
2. Stress reduction
3. Optimizing sleep
4. Regular exercise
5. Brain-stimulating activities
6. Creating a supportive daily routine
7. Maintaining a serene, non-toxic environment
8. Fostering social connections

While it may seem overwhelming to implement all these tools at once, Sandison reassures readers that any step taken toward better brain health is beneficial. The more tools incorporated, the greater the potential benefit due to their synergistic effects.

Building a Brain-Boosting Routine

One of the key strategies Sandison recommends is incorporating brain-healthy activities into daily routines. By creating consistent rhythms for these activities, they become automatic and effortless. This is especially crucial for caregivers and those already experiencing cognitive decline.

Evening and Morning Routines

Sandison suggests focusing on the "bookends" of your day – your evening and morning routines – to provide a supportive structure for brain health.

Evening routine examples:

• Engaging in relaxing activities after dinner (e.g., playing games, listening to music)
• Pre-bedtime ritual (e.g., warm bath, reading)
• Implementing good sleep hygiene practices (dimming lights, setting a consistent bedtime)

Morning routine examples:

• Upgrading your morning beverage (e.g., adding healthy fats to coffee)
• Meditating or spending time in nature
• Practicing oil pulling for better oral health (linked to brain health)

Organizing Your Days and Weeks

Beyond morning and evening routines, Sandison emphasizes the importance of organizing your days and weeks to include:

• Cognitive engagement
• Creativity
• Physical activity
• Connection with others

She notes that one activity can often serve multiple purposes. For example, a nature walk with a friend provides both exercise and social connection.

Practical Steps to Get Started

1. Keep a journal dedicated to your brain health journey
2. Set clear intentions for what you want to achieve in the next six months
3. Analyze your current schedule and look for opportunities to free up time for new brain-healthy habits
4. Create an ideal week schedule that incorporates brain-healthy activities
5. Seek support from family, friends, or professionals

Sandison emphasizes the importance of a compassionate approach, both towards yourself and your care partner if you're a caregiver. She reminds readers that progress, not perfection, is the goal.

The Power of Exercise for Brain Health

Sandison dedicates a significant portion of her book to discussing the crucial role of exercise in maintaining and improving cognitive function. She explains that physical activity does far more than just burn calories:

1. Increases blood flow to the brain, delivering vital oxygen and nutrients
2. Flushes away waste products from the brain
3. Increases the volume of the hippocampus, a key brain region for learning and memory
4. Triggers the release of molecules that act as "fertilizer" for the brain, promoting new neuron growth and connections

Beyond brain health, exercise offers numerous other benefits:

• Creates a positive hormonal feedback loop
• Helps build and maintain muscle mass
• Strengthens bones
• Improves mood
• Decreases pain
• Boosts energy
• Positively influences gene expression

Types of Exercise for Optimal Brain Health

Sandison recommends a well-rounded approach to exercise:

1. Aerobic exercise: The foundation of a brain-healthy exercise routine

   • Aim for 150 to 200 minutes per week
   • Examples: brisk walking, jogging, swimming

2. Strength training: Crucial for building muscle and bone density

   • At least two sessions per week

3. Dual-task training: Combines physical movement with a cognitive challenge

   • Example: briskly walking while counting backward from 100

Getting Started with Exercise

For those new to exercise, Sandison suggests:

1. Begin with daily walks
2. Gradually increase intensity and duration
3. Incorporate strength training and dual-task exercises as fitness improves

For caregivers, Sandison emphasizes making exercise fun and appealing to the person's interests:

• Nature walks to "visit" a favorite tree or statue
• Balloon volleyball for those with limited mobility
• Dance classes for the socially inclined

The key is to find ways to incorporate movement that feels enjoyable and purposeful, rather than like a chore.

The Brain-Boosting Power of Diet

Sandison identifies diet as another crucial factor in protecting and enhancing brain health. She particularly emphasizes the potential of the ketogenic diet in reversing signs of cognitive decline.

The Ketogenic Diet and Brain Health

The ketogenic diet is a high-fat, low-carb eating plan that switches the body's primary fuel source from glucose to ketones. Sandison explains that this shift can lead to remarkable improvements in cognitive function, citing examples of patients who regained lost abilities after adopting the diet.

Benefits of the ketogenic diet for brain health:

1. Improved memory function
2. Stabilized mood
3. Increased energy levels
4. Reduced inflammation
5. Better heart health

How the ketogenic diet works:

• Drastically reduces carbohydrate intake
• Replaces those calories with healthy fats (e.g., avocados, olive oil, nuts)
• Shifts the body's primary fuel source from glucose to ketones

Implementing the Ketogenic Diet

Sandison acknowledges that transitioning to a ketogenic diet can be challenging. Some people may experience temporary side effects like fatigue or cravings. She offers the following advice:

1. Stay hydrated
2. Ensure adequate mineral intake
3. Be patient as your body adapts to its new fuel source

Sandison emphasizes that the ketogenic diet isn't meant to be a permanent lifestyle change. The goal is to achieve metabolic flexibility, where the body can easily switch between burning glucose and ketones. For those seeking to reverse cognitive decline, she recommends:

1. A three to six-month period of strict adherence
2. Followed by cycling in and out of ketosis

Practical steps for implementing the diet:

1. Familiarize yourself with keto-friendly foods
2. Learn to read nutrition labels carefully
3. Consider investing in tools like ketone testing strips

For caregivers introducing the diet to a loved one with cognitive impairment, Sandison suggests:

• Emphasizing the delicious foods that can be enjoyed rather than focusing on restrictions
• Cooking together
• Finding creative ways to celebrate special occasions without traditional carb-heavy foods

While Sandison mentions other brain-healthy diets like the MIND diet, she highlights the ketogenic diet for its potential to not just reduce risk, but potentially reverse cognitive decline by providing the brain with its optimal fuel source.

Creating a Brain-Nourishing Environment

Sandison emphasizes the importance of our living environment in supporting brain health. She outlines two main priorities for creating a brain-nourishing space:

1. Reducing toxic exposure
2. Promoting relaxation and renewal

These principles can be applied throughout the home, from the bedroom to the kitchen, and even extend to outdoor spaces.

The Bedroom: Creating a Sleep Sanctuary

Sandison offers several suggestions for optimizing the bedroom for better sleep:

1. Use organic bedding to reduce chemical exposure
2. Maintain a cool temperature between 65 to 69 degrees Fahrenheit
3. Minimize light pollution
4. Consider using white noise to mask disruptive sounds

The Kitchen: Minimizing Toxic Exposure

As the place where we nourish our bodies, the kitchen is crucial for brain health. Sandison recommends:

1. Replace plastic containers with glass or stainless steel
2. Swap out non-stick cookware for safer alternatives like cast iron or ceramic
3. Organize the fridge and pantry to make healthy eating easier
4. Consider hiding knobs on the stove and sharp knives if safety is a concern for those with cognitive decline
