The Final Three Letters in B.R.I.G.H.T M.I.N.D.S

“The N is neurohormone deficiency — testosterone’s really important for brain health too. You don’t want too much because then your libido will go up and your empathy will go down, but low testosterone goes with depression, anxiety, and low energy. Thyroid, DHA, testosterone, estrogen, progesterone, and so on [are all] hormone tests [you should get]. D is diabesity, which is a combination of [being] overweight and high blood sugar. Either one is a mental health/brain health risk factor, and 50% of the population is either diabetic (14%) or pre-diabetic (36%.) That’s a disaster.” – Dr. Daniel Amen

Obesity and diabetes are bad for us because they atrophy our brain, making it smaller and killing the new stem cells being made in the hippocampus — that’s 700 cells a day simply being born and dying right away as opposed to connecting and multiplying functionality neurons in the brain to help your mood and memory. 

“What’s interesting [is] I’m 66, my youngest is 17 getting ready to go off to college, and we produce the same number of stem cells every day. Hers are more likely to stay than an older person’s because the blood flow to most 66-year-olds is not healthy. That’s why aging is progressive. [Unfortunately —] this will horrify you — 50% of people will have dementia if fortunate enough to live to 85 or beyond. [That’s] a one in two chance of losing my mind — that’s why I’m serious about this.” – Dr. Daniel Amen 

Finally, we come to the 11th area to focus on in BRIGHT MINDS — the S.

“Sleep [is] absolutely essential. Autophagy is what happens when you sleep [and] your brain cleans itself. It’s a system called the glymphatic system. When you’re asleep, [it’s] literally cleaning the synapses in your brain. If you’re not sleeping six and a half, seven, eight hours a night — trash is building up in your brain and making you more likely to be depressed, have brain fog, [or even be] overweight. Sleep integrates what we learn during the day and it compares it to our experience from the past and then decides what to keep and what to let go of. If you’re not sleeping well, or you’re drinking to put yourself to sleep, it damages REM sleep, which is the most restorative sleep.” – Dr. Daniel Amen

It’s great to learn all the tools with BRIGHT MINDS as a guide on how to evaluate how we’re treating our brains. This is important because our brain uses 30% of the calories we consume and 20% of the blood flow, and 20% of the oxygen we breathe goes to our brain too. 

We’ve spoken about how alcohol damages the brain in the previous post, now Dr. Amen addresses the effects of marijuana. 

Research on Marijuana and the Brain

With so many people talking about the positive impact marijuana has had on them, I’d like to understand what Dr. Amen’s research says — even at the risk of upsetting some of you! 

“I knew it was trouble right after I started looking at scans. It makes your brain look older than you are. If you smoke once a week, the problem is it’s fat-soluble, which means it stays in your body for 30 days, and so one decision can impact your brain for 30 days. I published a study with my colleagues from USC on a thousand pot smokers. We compared them to a group that never smoked. Every area of their brain [had] lower blood flow.” – Dr. Daniel Amen

It’s not just this study; Dr. Amen also conducted the world’s largest imaging study on 62,454 scans looking just at how the brain ages. The purpose was to look at the trajectory of aging from young kids to twenty-somethings up to 60-year-olds. 

“We looked at what accelerated aging in our database and schizophrenia was actually the worst. Their brains were 10 years older than the next worst, [which] was marijuana. It shocked us because we looked at alcohol, smoking, depression, and ADHD [and yet] it was marijuana. I’m very concerned. I’m a fan of legalizing marijuana because please don’t put people who smoke pot in jail, but let’s not say it’s healthy for us because it’s not. Kids who smoke, teenagers who smoke or do use edibles have a higher incidence of anxiety, depression, and suicide.” – Dr. Daniel Amen

There are medical examples where marijuana helps people, and this is why Dr. Amen doesn’t condemn the use of it for medical purposes or in small doses. Again, as Dr. Amen has discussed using BRIGHT MINDS — the question should always be “Are my thoughts, activities, food, behaviors loving, or hurting my brain?”

One way to find out is to get a scan of your brain. Another way is to think about how good your memory is.

Improve Your Memory

Before we finish today, I want to talk about memory, especially now that we have everything and all information at our fingertips available without needing to remember anything anymore. We used to remember phone numbers, but now everything is programmed at one click of a button. How important is memory training for us as humans in a world of memory lack, and what are a few things we could do to increase the ability to remember?

“If you use it, you get to keep it. If you don’t use it, you’ll lose it. It’s really important. Now, we’re probably not going to be remembering phone numbers because we have our auxiliary brains, but our auxiliary brain is causing Alzheimer’s to be diagnosed three or four years later when it’s actually harder to get help. I would diagnose people when I first started in practice 30 years ago because their family would call me up and they say, ‘He’s getting lost in a place he’s lived in 30 years,’ but now you just have to go, ‘Hey, Siri, take me home,’ These auxiliary memories are actually causing people to be diagnosed later. We should always be working on brains. New learning is just absolutely essential, so Spanish is great, learning a musical instrument, and you should be doing things that are new and different.” – Dr. Daniel Amen

The best form of defense is prevention — and our brain health is no different. What new thing can you start to learn that will help your brain health? One place to start is getting the details on how to implement what Dr. Amen is spoken about with us.

Dr. Amen’s new book Your Brain Is Always Listening: Tame the Hidden Dragons That Control Your Happiness, Habits, and Hangups has so many incredible exercises on how to deal with any type of struggle or stress that you might have in your life right now, whether it be an addiction, negative thoughts, dealing with past traumas, or the reasoning behind them. The book’s exercises on how to overcome them are extremely powerful yet simple strategies you can start implementing in your life.

It’s become customary to ask my guest each week what their definition of greatness is:

“It’s pushing to do what you know you can do, despite what other people say.” – Dr. Daniel Amen

I want to leave you with this quote from RuPaul who said, “True wealth is having a healthy mind, body, and spirit. True wealth is having the knowledge to maneuver and navigate the mental obstacles that inhibit your ability to soar.”

Now is your time to soar in this life. I hope this episode and this interview with Dr. Daniel Amen gave you some tools to support you in your growth so that you can soar and move forward.

To Greatness,
