Adhd How Anyone Can Improve Their Focus

High-Level Overview

In this long solo episode, Andrew Huberman explores attention deficit hyperactivity disorder (ADHD) and, more broadly, how anyone can sharpen their ability to focus, filter out distraction and remember information. He opens with a caution against self-diagnosis, noting that a real ADHD diagnosis should come from a psychiatrist, physician or well-trained clinical psychologist, and then describes the condition's surprising features: people with ADHD can hyperfocus on what they love, struggle with time perception and working memory, and are no less intelligent than anyone else. From there he moves into the neuroscience, explaining how dopamine acts as a conductor that keeps the brain's resting and task networks out of sync.

The tone is explanatory and even-handed, mixing detailed neuroanatomy with personal stories, including an overdose of chocolate espresso beans given to a friend's kids, a four-and-a-half-hour lecture on half a dose of armodafinil, and the tricks he learned for steadying his hands during brain surgery. The conversation flows from symptoms to circuits and chemistry, through prescription stimulants and diet, to behavioral tools, supplements, transcranial magnetic stimulation and, finally, the role smartphones play in eroding everyone's attention.

The Discussion Explores:

• What ADHD is and isn't: genetics, prevalence, hyperfocus, time blindness, the pile system and working memory
• How dopamine coordinates the default mode network and task networks, and the low-dopamine hypothesis
• Why stimulants like Ritalin and Adderall calm and focus people with ADHD, and why early treatment may matter
• Diet: the oligoantigenic elimination diet, sugar, and the difference between mediating and modulating attention
• Attentional blinks, open monitoring, panoramic vision and a single 17-minute session that improves focus
• Blinking, dopamine and time perception, plus visual focus training and fidgeting tools
• Supplements and newer compounds: omega-3s, phosphatidylserine, alpha-GPC, L-tyrosine, modafinil and Noopept
• Transcranial magnetic stimulation and why smartphone use may be inducing ADHD-like problems

Deep Dive into Main Ideas

What ADHD Looks Like

ADHD, formerly called ADD, appears in the medical literature as early as 1904 and was renamed in the mid to late 1980s once clinicians recognized that hyperactive kids also had attention problems. It has a strong genetic component: Huberman cites up to a 75% chance of ADHD if an identical twin has it, about 50 to 60% for a fraternal twin, and 10 to 25% if a parent has it. Current estimates put it at roughly 10 to 12% of children, about half of whom improve with proper treatment. He is emphatic that ADHD has nothing to do with intelligence, whether IQ or emotional, musical or spatial intelligence. There is also growing concern about adult ADHD, either missed in childhood or possibly induced by the constant attentional pulls of smartphones, email and social media.

For the episode, he treats attention, focus and concentration as the same thing: attention is perception, choosing which of many incoming senses to notice. Impulse control is separate, since it means blocking perceptions out. People with ADHD are distractible, impulsive, easily annoyed and sometimes highly emotional, yet they can achieve laser hyperfocus on things they love, such as video games or drawing. Their difficulty is engaging attention for things they don't want to do. They often run late and procrastinate, but can manage time well under a real deadline. Many use a pile system for organizing belongings that makes sense only to them and doesn't work well. And while long-term memory is often good, working memory, keeping a phone number in mind long enough to type it in, is often impaired, a feature shared with frontotemporal dementia and age-related cognitive decline.

Dopamine as Conductor of the Brain's Networks

The feelings we describe as enjoyment and curiosity have a clear neurochemical signature: dopamine. Dopamine narrows visual and auditory focus into a tunnel, directs attention outward (exteroception), and drives motivation and wanting. Huberman then describes two sets of brain circuits. The default mode network, active when we are idle and letting the mind wander, includes the dorsolateral prefrontal cortex, the posterior cingulate cortex and the lateral parietal lobe, which normally fire in sync like drums, guitar and bass in a band. The task networks, centered on the medial prefrontal cortex, make us goal-directed and suppress impulses like the urge to stand up or scratch your nose.

In a typical brain, these two systems are anti-correlated, working in seesaw fashion. In ADHD, and in anyone who has slept poorly, the default mode network is less synchronized internally, and, surprisingly, the default mode and task networks are more correlated with each other, like band members all playing melody with nobody keeping the beat. Imaging studies show that as people improve with treatment or age out of ADHD, the networks become anti-correlated again. Dopamine acts as the conductor that tells each network when to play. A 2015 paper in Biological Psychiatry, first author Spencer, formalized the low-dopamine hypothesis: when dopamine is too low, neurons fire when they shouldn't, like instruments playing through the pauses.

Self-Medication and How Stimulant Medications Work

This framework reframes the long-observed tendency of people with ADHD to seek out stimulants: six cups of coffee, cigarettes, cocaine or amphetamine in adults, and sugary foods in kids. Rather than simply reflecting poor impulse control, this may be self-medication, since all of these raise dopamine. In people with ADHD, they tend to calm and focus rather than rev up, the opposite of what happens in children without ADHD, as Huberman learned when he gave a friend's kids dark chocolate espresso beans and watched them go bonkers.

The main prescription drugs, Ritalin (methylphenidate), Adderall (amphetamine and dextroamphetamine), and modafinil and armodafinil, all raise dopamine and norepinephrine, with a small effect on serotonin. Huberman stresses that Ritalin and Adderall are structurally and chemically very similar to street amphetamine and cocaine, which many parents may not realize, yet at appropriate doses and under a board-certified physician's care, many people with ADHD get excellent relief. He notes that up to 25% of college students and perhaps 35% of people aged 17 to 30 use Adderall without a diagnosis, now more than use cannabis in that age group. Choosing between drugs involves pharmacokinetics: long-release forms may leave you too alert at some times of day and not alert enough at others.

Why Treat Early: A Pediatric Neurologist's View

Huberman consulted a longtime colleague, a pediatric neurologist with an MD and PhD who treats ADHD and epilepsy in patients aged 3 to 21 and whose own young son is showing signs of ADHD. Asked about giving young kids amphetamine, she said it seems crazy on its face, but with the lowest possible dose, adjusted as the child grows, she has seen more kids benefit than not. When he asked why not wait until puberty, when hormones naturally strengthen the brain's executive and impulse-control circuits, her answer was neuroplasticity: it is exceedingly high from about age 3 to 12 or 13 and tapers after about 25. Stimulants let children's task networks come online so they can learn what focus feels like while the brain is most moldable.

Huberman adds a trick from his own college years: when he couldn't focus on a subject, he would tell himself it was the most interesting thing in the world, and often ended up genuinely loving it. Kids with ADHD can't simply do that, which is where medication can help. He is careful to add, "I'm not a doctor. I don't prescribe anything. I'm a professor. So I profess things."

Diet: Elimination Diets, Sugar, and Mediation vs Modulation

Huberman reviews the 2011 Lancet study by Pelsser and colleagues, in which 100 children followed an oligoantigenic diet that removed foods they had mild antibody reactions to, in a randomized crossover design. Improvements in focus, impulsivity and even the ability to sit still were dramatic, with every effect at p less than 0.001. The study set the world on fire, followed by healthy skepticism about its design, though many later studies and meta-analyses suggest diet can meaningfully reduce symptoms, sometimes enough to avoid or taper medication. He also points to a 2020 Frontiers in Psychiatry paper on the same diet. His neurologist colleague's view was clear: "elimination of simple sugars has a dramatic and positive effect", something she has seen in many dozens if not hundreds of patients. All four neurologists and psychiatrists he consulted agreed kids with ADHD should avoid high-sugar foods, though elimination diets remain controversial because avoiding foods like nuts may itself create allergies.

He then introduces a key distinction. Some things mediate attention directly, like the dopamine circuits that drugs such as Ritalin and Adderall target. Others modulate it indirectly, like sleep: stay up for two nights and your focus collapses, but sleep isn't the mechanism of focus. Diet and omega-3s, he argues, are modulators. They can help, especially when ADHD is mild, caught early or combined with medication, but they won't be the switch that flips everything. Keeping this distinction in mind helps cut through the flood of ADHD diet and supplement claims online.

Attentional Blinks and a 17-Minute Fix

Drawing on the book Altered Traits by Daniel Goleman and Richard Davidson, Huberman explains attentional blinks. When you find Waldo in a Where's Waldo picture, your brain briefly celebrates, and in that moment you miss a second Waldo right next to him. In the lab, people watching a stream of characters for an R and a Z tend to spot the R and miss the Z, even though they can see either one alone. People with ADHD, children and adults, have many more attentional blinks. This suggests their problem may be over-focusing on some things and thereby missing others, rather than an inability to focus.

The remedy is what the book calls open monitoring. One route is panoramic vision: consciously dilating your gaze to take in the ceiling, floor and walls while still looking ahead, which engages a separate visual stream that is also better at processing events in time and lets people catch multiple targets. The other is striking: published studies found that a single session of about 17 minutes sitting quietly with eyes closed, focusing on breathing and bodily sensations and bringing the mind back when it drifts, significantly reduced attentional blinks in a near-permanent way without further training. Attentional blinks also increase with age, and researchers are exploring whether this practice can offset age-related cognitive decline. Huberman doesn't expect anyone to take up regular meditation, but thinks most people can manage one 17-minute session.

Blinking, Time Perception and Training Focus

Actual eye blinks matter too. A Current Biology paper by Terhune, titled "time dilates after spontaneous blinking", found that blinks reset our perception of time, like the clapperboard between takes in a film. Blink rate is controlled by dopamine: higher dopamine means fewer blinks, finer slicing of time and overestimating how long things took, while lower dopamine means underestimating intervals. That helps explain why people with ADHD, with low dopamine, lose track of time and run late. Stimulants, including caffeine, reduce blinking, and a study found that long-term cannabis users blink much less, which Huberman interprets as cannabis increasing focus while impairing memory of what was focused on.

This points to a trainable tool. A study titled "Improvement of Attention in Elementary School Students through Fixation Focus Training Activity" had children first do physical movement to burn off the urge to move, then focus on a close target like their hand for 30 to 60 seconds, then on targets progressively further across the room, for just a few minutes a day. It greatly improved their focus on other material, in part through controlling their blinks. Schools now also let kids with ADHD use fidget tools like a rubber band on the desk. Huberman explains why with a surgery story: the harder you try to hold your hands still, the more they shake, but subtly tapping a foot or bouncing a knee gives the premotor circuits an outlet so the hands steady. The same explains why pacing or gesturing helps nervous public speakers. He also cites a study showing people with ADHD have normal interoceptive awareness, measured by counting their own heartbeats; the fidgety child is not oblivious to how they feel but is working hard to regulate attention.

Medications Revisited and Supplement Options

Huberman points to a long review by Esposito and colleagues in Frontiers in Bioscience that places Ritalin, Adderall and caffeine alongside methamphetamine and cocaine, underlining how blurry the line is between drugs of treatment and drugs of abuse. Apart from caffeine, these carry risks of addiction, sexual side effects from vasoconstriction, increased heart rate and cardiovascular strain, and diminishing returns with repeated use. He sees promise in drug schedules and in pairing medication with behavioral training, such as movement followed by visual focusing, while the brain is chemically more plastic, then possibly tapering off. Modafinil and armodafinil are weaker dopamine reuptake inhibitors that also act on the orexin (hypocretin) system, the one disrupted in narcolepsy, as discovered by his Stanford colleagues Emmanuel Mignot and Seiji Nishino. His own experience with half a prescribed dose of armodafinil for jet lag ended with a friend telling him he had been talking for four and a half hours; he concluded the right dose for him was zero.

On supplements, he says omega-3s modulate attention modestly; for attention, the key threshold appears to be more than 300 mg of DHA per day, which people taking 1,000 to 2,000 mg of EPA for mood almost certainly get. Phosphatidylserine at 200 mg per day for two months reduced ADHD symptoms in children in two double-blind studies of 147 and 36 kids, with effects enhanced by omega-3s. Ginkgo biloba has minor effects and gives him splitting headaches. Alpha-GPC, a form of choline that boosts acetylcholine from the brainstem's pedunculopontine nucleus and the forebrain's nucleus basalis, is typically used at 300 to 600 mg to aid focus, with up to 1,200 mg studied for age-related decline. L-tyrosine, a dopamine precursor, can help but is hard to dose, from 100 to 1,200 mg, and he urges caution for anyone with mood disorders, bipolar disorder or schizophrenia. He mentions PEA, points listeners to Examine.com for details, and describes the racetams, including Noopept at 10 mg twice daily, which acts on the acetylcholine system and has shown promise for focus problems after concussion or vascular injury. Throughout, he stresses checking with a doctor.

Transcranial Magnetic Stimulation

TMS uses a coil placed over the skull to send magnetic pulses that can increase or decrease activity in specific brain regions without surgery. Its precision is, in Huberman's words, not a cannon but not a needle. He describes having a coil placed over his own motor cortex in a lab: while it was on, he could not tap a pencil, and as soon as it was off, he could. A colleague is now using TMS to stimulate the prefrontal task circuits in children and adults with ADHD, combined with a focused learning task, and clinical trials are comparing this drug-free approach with medication. He is optimistic that combinations of drugs, technology and behavioral training will keep improving.

Smartphones and the Erosion of Attention

Finally, Huberman argues that smartphones may be inducing a kind of ADHD. The phone captures our whole attentional window while rapidly switching contexts inside it. A 2014 population-based study of about 7,100 adolescents found that to avoid attention problems, teens needed to keep smartphone use under 60 minutes a day. Extrapolating, he suggests about two hours a day as an upper limit for adults. He cites Cal Newport, author of Deep Work and A World Without Email, paraphrasing his view that "the brain does not do well with constant context switching." Since success in school, relationships, sport and creative work is proportional to the focus we bring, limiting phone use may be one of the best ways to protect it.

Conclusion

Huberman reframes ADHD not as an inability to focus but as a dopamine-regulated timing problem: the brain's idle and task networks fail to take turns, attention over-locks onto some things and blinks past others, and time slips away. That framing explains why stimulants, which look chemically like street drugs, can calm and focus people with ADHD, why early treatment during peak plasticity may help, and why cutting simple sugars and possibly allergenic foods can reduce symptoms. It also opens the door to tools anyone can use: one 17-minute session of quiet interoceptive attention, panoramic vision to widen awareness, brief visual focus training after some movement, subtle fidgeting to steady the body, supplements like omega-3s, phosphatidylserine and alpha-GPC used thoughtfully with a doctor, and firm limits on smartphone use. Combined, he suggests, these behavioral, nutritional, pharmacological and technological approaches can help both people with ADHD and everyone else bring more focus to what matters.
