Episode: Is Your Memory Worse Than It Was 10 Years Ago?

Hosts: Dr. Daniel Amen & Tana Amen
Date: November 28, 2025

Main Theme

This episode centers around memory loss—how common it is, what worsening memory may signal, and actionable steps everyone can take to protect and improve their brain. Dr. Daniel Amen draws on decades of clinical experience and brain imaging research to empower listeners with knowledge about maintaining sharp memories and independence as they age.

Key Discussion Points & Insights

1. The Universality and Importance of Memory Lapses

Everyone experiences moments of forgetfulness, whether it’s losing your phone, forgetting names, or struggling for words.
Implication: If these lapses are increasing or significantly worse than a decade ago, it could predict future trouble with memory.

“People who complain about memory loss have an 80% chance it will get worse unless they do something about it.” — Dr. Daniel Amen [00:30]

2. The Personal and Social Value of Memory

Memory defines our sense of self, relationships, and independence:
- Holds treasured life moments.
- Essential for professional and personal success.
- Critical for maintaining autonomy in old age.
Lightheartedly, Dr. Amen warns against forgetting important dates:

“Just forget your anniversary one time and see what happens.” — Dr. Daniel Amen [01:10]
Guarding your memory is synonymous with guarding your independence.

“If you value your independence, pay attention.” — Dr. Daniel Amen [01:25]

3. The “11 Risk Factors” Framework for Memory Rescue

Dr. Amen introduces a core concept: memory rescue relies on identifying and addressing 11 primary risk factors that harm the brain.
- Nearly all of these factors are preventable or treatable with lifestyle changes.
“Memory rescue is based on one very simple idea...you have to prevent or treat the 11 major risk factors that destroy your brain.” — Dr. Daniel Amen [01:28]
Having this knowledge is critical and can change the trajectory of your brain health.

4. The Hippocampus — The Brain’s “Seahorse Twins”

Introduction to the hippocampus:
- This brain structure (Greek for “seahorse”) is vital for learning, memory, and mood.
- There are two hippocampi, nicknamed "Scarlet and Sam, the seahorse twins."
- The hippocampus is one of the first regions affected in Alzheimer’s.
Neurogenesis: The hippocampus generates up to 700 new cells daily.

“Your hippocampus makes up to 700 new cells every day, which I think of as baby seahorses.” — Dr. Daniel Amen [02:08]
Actions that help hippocampal cells ("baby seahorses") survive:
- Taking fish oil
- Listening to the right kind of music
Actions that hurt them:
- Consuming concentrated sugars like fruit juice
“There are specific things you can do to help them survive and thrive, such as taking fish oil or listening to the right type of music. And there are things you can do to hurt them, such as drinking fruit juice because it’s concentrated sugar.” — Dr. Daniel Amen [02:19]

5. Lessons from Decades of Brain Imaging

Dr. Amen shares findings from over 135,000 SPECT scans performed at Amen Clinics on patients from 111 countries.
- SPECT (Single Photon Emission Computed Tomography) measures blood flow and activity in the brain, showing how it functions.
A key, sobering insight: brain changes can begin long before symptoms appear.

“One of the most frightening lessons...is that these negative changes happen in the brain years before you notice any trouble. Scarlet and Sam literally start dying long before you can’t find your way home.” — Dr. Daniel Amen [02:45]

6. Hope and Empowerment: Your Brain Is Changeable

Despite genetic or historical tendencies, proactive changes can profoundly affect brain health.

“Your brain’s history is not your destiny. You can make your brain better, which is a message that is deeply personal to me.” — Dr. Daniel Amen [03:00]

Notable Quotes & Memorable Moments

Dr. Daniel Amen:
- “Every day, you are making your brain better or you are making it worse.” [00:02]
- “Memory is the treasure chest that holds our most precious moments.” [00:52]
- “Of course, not everyone can prevent memory loss, but there are so many things you can do to help your brain.” [01:37]

Every day. You are making your brain better or you are making it worse. Stay with us to learn how you can change your brain for the better every day. Ever misplace your phone? Forget someone's name? Or struggle to find the right words? Of course you have. It happens to all of us. But if you find it happening more and more, it may predict trouble. Especially if your memory is worse than it was 10 years ago. People who complain about memory loss have an 80% chance it will get worse unless they do something about it. Memory makes us who we are. It allows us to keep our loved ones close, even when they're far away. Memory is the treasure chest that holds our most precious moments. From your first kiss to the births of your babies and grandbabies. A healthy memory is imperative for success at work and in relationships. Just forget your anniversary one time and see what happens. Memory is also essential for staying independent. I love my four children, but honestly, I never want to have to end up living with them. I never want to be a burden, and I don't want them telling me what to eat, what to wear, or trying to take my driver's license away from me. If you value your independence, pay attention. Memory rescue is based on one very simple idea. To strengthen your memory or get it back. If you think it's headed for trouble. You have to prevent or treat the 11 major risk factors that destroy your brain. And the good news is that almost all of them are either preventable or treatable. Of course, not everyone can prevent memory loss, but there are so many things you can do to help your brain. I believe it's critical for you to have this information. In talking about memory, it's important to learn about a special part of your brain called the hippocampus, which is Greek for seahorse because it's shaped like one. In fact, you have two of them. I'll refer to them as Scarlet and Sam, the seahorse twins. They're involved with learning memory and your mood. And they are one of the first areas of the brain to that die in Alzheimer's disease. But did you know that your hippocampus makes up to 700 new cells every day, which I think of as baby seahorses. And there are specific things you can do to help them survive and thrive, such as taking fish oil or listening to the right type of music. And there are things you can do to hurt them, such as drinking fruit juice because it's concentrated sugar. The lessons come from the brain SPECT imaging work we do at Amen Clinics. SPECT measures blood flow and activity. It looks at how your brain works. Over the past three decades, we've performed more than 135,000 scans on patients from 111 countries. One of the most frightening lessons we've learned from Spectrum is that these negative changes happen in the brain years before you notice any trouble. Scarlett and Sam literally start dying long before you can't find your way home. But the exciting news is that you can do something about it. Your brain's history is not your destiny. You can make your brain better, which is a message that is deeply personal to me.
