The Diary of a CEOThe ADHD Doctor: “I’ve Scanned 250,000 Brains” You (Steven Bartlett) Have ADHD!!! Dr Daniel Amen
CHAPTERS
- 3:20 – 7:10
Opening, Stakes, and Mission to End Mental Illness
Steven asks Amen why listeners should stay, prompting Amen to frame brain health as the foundation of better love, money, and longevity. He outlines his ambition to 'end mental illness' by rebranding it as brain illness and focusing on brain health rather than just diagnoses and drugs.
- •Brain is involved in everything: thinking, feeling, acting, relating, earning.
- •Amen rejects the term 'mental illness' as shaming and inaccurate; prefers 'brain disorder.'
- •Standard care ignores diet, exercise, sleep, toxins, and brain injury while prescribing medications.
- •Amen claims a revolution in brain health could halve the incidence of mental health disorders.
- 7:10 – 18:20
Scanning Steven’s Brain: Method, Findings, and ADHD Revelation
Amen explains the assessment protocol Steven underwent: attention testing, questionnaires, and SPECT brain imaging. Comparing a healthy scan with Steven’s, he identifies signs of toxicity, head trauma, underactive frontal and temporal lobes, and a pattern consistent with over‑focused ADHD and emotional trauma.
- •Conners Continuous Performance Test used to measure attention and impulse control; Steven scores 'fine' but history suggests ADHD.
- •Healthy SPECT scans show full, even, symmetrical blood flow and hot cerebellum; Steven’s is 'bumpy' with low areas.
- •Indicators of toxins lead to questions about alcohol, drugs, mold, heavy metals; Steven recalls moldy, hoarder‑like childhood home.
- •Reduced left prefrontal and temporal activity linked to ADHD symptoms and irritability/short fuse.
- •Soccer‑related heading and collisions likely caused mild traumatic brain injury; such impacts often go unnoticed but have lifelong effects.
- •Amen classifies Steven as having 'over‑focused ADD': hyperfocus on interests, poor focus when bored, emotional trauma 'diamond' pattern.
- 18:20 – 25:00
ADHD, Family Patterns, Creativity, and Career Fit
The discussion turns to how ADHD showed up in Steven’s childhood, education, and family, and how it shapes his entrepreneurial style. Amen highlights both the vulnerabilities and advantages of ADHD, emphasizing the importance of life design, support teams, and potentially targeted treatment.
- •Steven’s school history: 'useless student,' constant exclusions, unable to engage in uninteresting classes, serial quitting (school, university).
- •He describes himself as extremely good at not doing things he isn’t interested in and thriving in creative, marketing‑driven entrepreneurship.
- •Amen notes ADHD is highly genetic; Steven suspects his mother (irritability, messiness, poor handwriting) more than his organized father.
- •Over‑active frontal lobes correlate with rule‑bound, organized personalities; slightly underactive ones with creativity and less rule adherence.
- •Many CEOs and founders have ADHD traits and excel when they hire organized people to complement them.
- •Scans give powerful 'awareness' that the brain is real, modifiable, and not a fixed, invisible background.
- 25:00 – 34:00
You’re Not Stuck: How Daily Choices Rewire the Brain
Amen drives home that the brain can be improved or harmed every day by our behaviors. He begins detailing specific habits that damage or heal the brain, starting a practical tour of lifestyle levers.
- •Every day your actions either make your brain better or worse.
- •Seven‑year‑olds can correctly sort most behaviors as good/bad for the brain—knowledge isn’t the main problem, behavior is.
- •Fruit juice is misleadingly 'healthy'; stripping fiber turns sugar into a rapid, toxic hit.
- •Brain health should be approached like performance optimization, not just fixing pathology.
- 34:00 – 43:20
Sugar, Obesity, Blood Flow, and Caffeine
Focusing on blood flow and metabolism, Amen explains how sugar, obesity, caffeine, and even erectile dysfunction signal and drive poor brain health. He gives specific dietary and supplement strategies to improve circulation.
- •Sugar is pro‑inflammatory, promotes diabetes and obesity, damages blood vessels, and reduces brain blood flow.
- •Amen’s studies on 35,000 people: as weight increases, brain size and function decline.
- •Obesity is strongly linked to depression and dementia via inflammation and vascular damage.
- •Caffeine acutely constricts blood flow to the brain; high doses plus sleep disruption may accelerate brain aging.
- •Ideal: limit caffeine (~100 mg/day), avoid nicotine, use exercise and blood‑flow‑supporting foods (beets, oregano, rosemary, cinnamon).
- •Ginkgo biloba is cited as a potent blood‑flow booster; Amen calls ginkgo‑user brains 'the prettiest' on SPECT.
- •Erectile dysfunction at 40 or 70 is a whole‑body blood flow problem, not just a 'local' issue.
- 43:20 – 55:00
Toxins, Everyday Products, and the BRIGHT MINDS Framework (Part 1)
Amen introduces the BRIGHT MINDS framework and dives into toxins and inflammation, connecting everyday exposures—from shaving foam to mold—to long‑term brain harm. He emphasizes practical tools for identifying and reducing toxic load.
- •Toxins include alcohol, marijuana, heavy metals, mold, anesthesia, and common personal‑care products.
- •Think Dirty app lets you scan items (toothpaste, mouthwash, deodorant, cosmetics) and see a 0–10 toxicity score.
- •Amen replaced decades‑long use of a '9/10' shaving foam (Barbasol) with a '2/10' product (Kiss My Face).
- •Endocrine‑disrupting chemicals in personal care may contribute to modern epidemics of low testosterone in men.
- •Inflammation drivers: low omega‑3 levels (93% of the population deficient), gum disease, poor diet.
- •Gum disease increases risk of depression and dementia; Amen becomes a 'flossing fool' after seeing the data.
- 55:00 – 1:05:00
Medication, ADHD Treatment Strategy, and the 'Glasses' Metaphor
Steven confesses strong reluctance to take any medication, prompting Amen to explain how to think about ADHD meds, side effects, and alternatives. He shares cases showing how stimulants can normalize underactive brains when appropriately used.
- •Amen never makes a diagnosis from a scan alone; he integrates scans with history, tests, and symptoms.
- •He differentiates side effects of medication from 'side effects of not taking medication'—the life costs of untreated ADHD.
- •Stimulants can activate sleepy prefrontal and cerebellar areas in ADHD brains, like glasses helping unfocused eyes.
- •Case of 'Sandy': IQ 144, near‑suicide, ADD, underachieving; on stimulant plus understanding, her life transforms (better marriage, parenting, completion of college).
- •ADHD and ADD are essentially the same diagnostic construct; the label changed in 1987, but half of sufferers are not hyperactive and get missed.
- •Amen is not anti‑medication but insists it should not be the first and only intervention; natural strategies (exercise, diet, structure, support) come first.
- 1:05:00 – 1:14:40
Killing ANTs and How Thoughts Change Brain Activity
Amen presents his 'kill the ANTs' framework to tame automatic negative thoughts, illustrating how thinking patterns instantly alter brain chemistry and blood flow. He outlines a simple, repeatable cognitive process to shift entrenched negativity.
- •Every thought triggers physical changes: negative thoughts constrict vessels, cool hands, tense muscles; positive thoughts warm hands and calm physiology.
- •People with ADHD are often drawn to negative thoughts because they’re stimulating.
- •The ANTs exercise: when sad/mad/anxious, write the thought down and ask: Is it true? Is it absolutely true? How do I feel/act with it? Without it? Then create and examine the opposite thought.
- •This process, inspired by Byron Katie, helps detach from untrue or unhelpful beliefs.
- •Experiment with Noelle Nelson: appreciating vs. hating herself produced radically different scans—in negativity, key regions (temporal, frontal, cerebellum) shut down.
- •Amen advocates 'accurate thinking with a positive spin' rather than naive optimism; some anxiety is useful (goal ~15/100, not zero).
- 1:14:40 – 1:26:40
Stress, Trauma, Brain Reserve, and EMDR
Building on ANTs, Amen explains how chronic stress and trauma program the brain, and why people respond so differently to similar events. He introduces the idea of 'brain reserve' and EMDR as a powerful treatment for trauma‑induced overactivity.
- •Chronic stress elevates cortisol, which shrinks hippocampal volume and impairs learning/memory.
- •Steven’s chaotic, hostile childhood likely trained his emotional brain to constantly scan for threat, contributing to school struggles.
- •Trauma appears as a 'diamond pattern' in the emotional circuitry on SPECT.
- •EMDR (eye‑movement desensitization and reprocessing) helps re‑process traumatic memories; highly effective for single‑incident traumas, longer but helpful for chronic trauma.
- •Amen stresses 'brain reserve': the pre‑existing strength of your brain (in utero conditions, early nutrition, childhood environment) determines whether a trauma yields growth or PTSD.
- •Raising brain reserve (diet, sleep, ant‑killing, exercise, connection) increases resilience to future shocks.
- 1:26:40 – 1:35:40
Brain‑Based Life Design: One‑Page Miracle and Media Diet
The conversation shifts to intentional life planning and the media we consume. Amen describes his 'one‑page miracle' exercise and argues that negativity‑driven news and content physically carve distorted highways in the brain.
- •One‑page miracle: on one page, define what you want in relationships, work, money, and physical/emotional/spiritual health.
- •Use it as a filter: is this behavior getting me what I want? Amen uses it to avoid saying hurtful things in his marriage.
- •The brain is lazy and habitual; you decide whether to build positive, accurate, or negative, distorted neural highways.
- •News is optimized for engagement, not truth; negativity sells and increases anxiety and pessimism.
- •Amen’s 'evil ruler' thought experiment: if he wanted to create mental illness, he’d encourage constant news consumption and fear.
- •Research he cites: starting the day with news makes people 27% less happy in the afternoon.
- •True crime binges before bed may not be ideal for sleep and emotional tone; contrast with his own nightly 'what went well' review.
- 1:35:40 – 1:42:40
Immunity, Vitamin D, COVID, and Infections
Amen covers the 'I' in BRIGHT MINDS—immunity and infections—highlighting vitamin D, COVID, and inflammation as major, underappreciated drivers of brain dysfunction. Steven connects this to a relative’s mental health decline after moving from Africa to the UK.
- •Vitamin D is critical for brain and immune health; darker‑skinned individuals in low‑sun countries are at high risk of deficiency and related mental health problems.
- •Steven suspects a very dark‑skinned relative’s apparent bipolar symptoms may be partly linked to long‑term vitamin D deficiency after migrating from Nigeria to the UK.
- •Reframing mental illness as brain health leads clinicians to test and correct deficiencies (like vitamin D, B12) rather than default to antipsychotics/mood stabilizers.
- •COVID is neuroinflammatory; post‑COVID scans often show a 'hot' emotional brain and low cortical activity, raising risks of anxiety, depression, irritability, suicidality, and dementia.
- •Case: Kendall Jenner’s post‑COVID scan revealed a hyperactive emotional brain that matched her new anxiety symptoms.
- 1:42:40 – 1:49:20
Approaching Depression: Why Before What, Brain vs. 'Broken'
Asked how to help someone too depressed to get out of bed, Amen insists on root‑cause evaluation instead of reflexive labeling and medicating. He attacks the 'broken brain' narrative and shifts to elite performance framing.
- •Depression is a symptom (like chest pain), not a root diagnosis; you must ask why: thyroid? anemia? infections? deficiencies? brain injury? toxins?
- •Treating depression with drugs alone while ignoring brain health is comparable to throwing pills at chest pain without cardiac workup.
- •Amen dislikes the 'broken' framing; prefers 'not optimized' and focuses on helping people become '10% more awesome.'
- •He notes 25% of Americans are on psychiatric drugs; good for pharma, bad for society if underlying drivers remain unaddressed.
- •Positioning treatment as elite performance optimization, especially for high‑functioning individuals, is more motivating and less stigmatizing.
- 1:49:20 – 1:57:00
Neurohormones, Diabesity, and the Central Role of Sleep
Amen completes BRIGHT MINDS by touching on hormones, diabesity, and sleep. He emphasizes sleep’s cleansing function, the dangers of sleep apnea, and several practical breathing and measurement tools.
- •Neurohormones: suboptimal thyroid, testosterone, estrogen, and others directly affect brain function and mood; testing and balancing them is essential.
- •Diabesity (diabetes + obesity) is the most common of the 11 risk factors; it lowers blood flow, increases inflammation, stores toxins, and accelerates aging.
- •Sleep supports the brain’s glymphatic system, which clears toxic proteins (e.g., beta‑amyloid) during deep sleep.
- •Sleep apnea (loud snoring, repeated breathing pauses, daytime fatigue) triples Alzheimer’s risk; its SPECT pattern resembles early Alzheimer’s.
- •Many with apnea refuse treatment due to discomfort with CPAP masks, but untreated oxygen deprivation is 'the worst thing' for the brain.
- •Amen recommends breath work (8‑second inhale, brief hold, 4‑second exhale, brief hold) repeated several times to break panic and raise heart‑rate variability.
- 1:57:00 – 2:08:00
Heart‑Rate Variability, Alcohol, and Why 'Social Drinking' Still Matters
Discussing HRV and alcohol, Steven recounts how wearables convinced him to quit drinking. Amen reinforces this with brain and cancer data, arguing that even modest alcohol intake measurably harms the brain and decision‑making.
- •Heart‑rate variability (HRV) measures beat‑to‑beat variation; higher HRV is linked to better resilience and lower anxiety, depression, and early death.
- •Factors that raise HRV: meditation, breath work, exercise, good sleep; factors that lower it: alcohol, illness, stress, ANTs.
- •Steven’s WHOOP data showed HRV crashing from ~150 to ~40 after even 1–3 glasses of wine, similar to being sick or severely stressed.
- •Amen cites data that any alcohol raises risk for seven cancers and shows SPECT evidence of lower brain activity in drinkers vs. abstainers.
- •Alcohol damages white‑matter 'highways' in the brain and impairs decision‑making; many of Amen’s patients’ crises are alcohol‑related.
- •He notes social pressure around alcohol and challenges it by asking pushers why they need you to drink.
- •Restaurants strategically offer bread and alcohol first because both drop frontal lobe function and encourage overspending.
- 2:08:00 – 2:18:00
Sex, Libido, Gender Brain Differences, and Relationships
Amen explores sex as a brain function, emphasizing blood flow, hormones, trauma, and individual brain types. He then presents large gender differences in brain perfusion and how they shape behavior, leadership, and risk profiles.
- •Libido and erectile function are largely blood‑flow and brain issues; fixing BRIGHT MINDS factors often improves sex life.
- •Assess hormones, address sexual trauma, and remember 'the biggest sex organ is the brain'—no forethought, no foreplay.
- •He gives a structured routine for partners with overactive cingulate (automatic 'no'): pasta (serotonin), walk (exercise), dark chocolate (PEA), baby powder (unconscious baby association), back rub, and timing within menstrual cycle.
- •Women and men have markedly different brain patterns: women show higher frontal and limbic activity; men lower frontal, less emotional activation.
- •Women’s stronger frontal lobes support impulse control, communication, and leadership; men are 14x more likely to go to jail.
- •Women have double the depression rates, likely from busier emotional centers; they also more often seek help, while men die by suicide more often due to violent methods and less disclosure.
- 2:18:00 – 2:27:00
Saunas, Cold Plunges, Exercise, Weight, and the Obesity Epidemic
Amen advocates saunas, exercise, and, selectively, cold plunges as brain‑support tools while describing the devastating neurological impact of obesity. He criticizes food marketing and portion sizes as a societal 'war' on brains.
- •Frequent sauna use (per Nordic studies) is linked to lower Alzheimer’s risk and aids detoxification (Amen used it in his mercury detox).
- •Exercise boosts blood flow, BDNF, serotonin, dopamine; walking speed in old age is a strong predictor of longevity.
- •Cold plunges can increase dopamine and help pain/inflammation and depression, but may be risky for those with heart disease.
- •As weight rises, brain size and function decrease; obesity reduces blood flow, increases inflammation, stores toxins, and harms self‑image and hormones.
- •Marketing (e.g., fast‑food ads pairing hyper‑palatable foods with attractive models) manipulates people into choices that damage brain and metabolic health.
- •Amen insists calories do matter, alongside quality; oversized portions and low‑fat, high‑sugar products helped trigger the obesity epidemic.
- 2:27:00 – 2:35:00
Screens, Social Media, Pleasure Centers, and Teenage Mental Health
Turning to screen time, Amen explains how constant digital stimulation wears out the brain’s reward centers and rewires expectations of pleasure. He connects heavy social media use to surging anxiety, depression, and suicide in young people, especially girls.
- •Phone buzzes, notifications, and endless scrolling deliver repeated dopamine hits to the nucleus accumbens (pleasure centers).
- •Overuse 'thrills these centers to death,' desensitizing them and making normal life feel flat.
- •3.5+ hours/day of screen time is associated with increased anxiety, depression, addiction, obesity, and ADHD symptoms; many teens far exceed this.
- •Fame itself (attention overexposure) can wear out reward systems; Amen has seen severe depression in high‑profile celebrities like Justin Bieber and Miley Cyrus.
- •Social media fuels harmful comparison, particularly in teenage girls, contributing to self‑hatred and rising suicide rates.
- 2:35:00
Happiness, Aging, and Implementing Brain‑Healthy Habits
In the final segment, Steven asks about happiness across the lifespan and reflects on how to operationalize Amen’s advice. Amen shares his evolving view of happiness as duty and the importance of scheduling a few key daily brain habits.
- •Some research suggests a U‑shaped happiness curve: lower in midlife, higher in youth and old age; Amen notes this may relate to reduced striving later in life but coexists with higher depression and dementia rates.
- •He views both negative thinking and happiness as habits that can be trained, e.g., nightly 'what went well' and noticing micro‑moments of joy.
- •Happiness is a 'moral obligation' because your mood states materially affect the brains and lives of people around you.
- •Self‑work on mood and brain health is framed as the most loving thing you can do for others.
- •Steven commits to turning a few chosen tools (breath work, evening gratitude, sleep focus, less caffeine, continued alcohol abstinence) into calendarized routines.
- •They close by highlighting the generational impact of brain health: improving one person’s brain tilts entire family lines, and thus society, in a better direction.
