10 Key Concepts
Attention
Attention is how we perceive the sensory world, focusing on some sensory inputs while filtering out others. People with ADHD often struggle to sustain this focused perception.
Impulse Control
Impulse control involves limiting our perception and putting 'blinders on' to sensory events in our environment. Individuals with ADHD often exhibit poor impulse control, leading to distractibility and impulsivity.
Working Memory
Working memory is the ability to keep specific information online and actively recycle it in the brain for immediate or short-term use, typically for a few seconds to a minute or two. This aspect of memory is frequently disrupted in people with ADHD.
Dopamine
Dopamine is a neuromodulator released in the brain that creates a heightened state of focus, narrowing our visual and auditory attention to external stimuli (exteroception). It acts like a conductor, coordinating brain networks for attention.
Default Mode Network
This network of brain areas is active when a person is at rest, not engaged in a specific task, or simply idling. In typical brains, it operates in an anti-correlated fashion with task networks.
Task Networks
These are brain networks that become active when a person is goal-oriented and engaged in a specific task, often working to suppress impulses. In typical brains, they are anti-correlated with the default mode network.
Low Dopamine Hypothesis of ADHD
This hypothesis suggests that insufficient dopamine levels in specific brain circuits lead to excessive and unnecessary firing of neurons, disrupting the coordination between default mode and task networks, thereby impairing focus and attention.
Attentional Blinks
Attentional blinks are temporary lapses in attention that occur after identifying a visual target, causing a brief inability to perceive other information immediately nearby. People with ADHD may experience more frequent attentional blinks.
Open Monitoring
Open monitoring is a state of attention achieved through panoramic vision, where one consciously dilates their gaze to perceive the entire visual field. This state allows for attending to and recognizing multiple targets simultaneously, reducing attentional blinks.
Acetylcholine
Acetylcholine is a neurotransmitter released from specific brainstem and basal forebrain nuclei that activates particular brain locations. It plays a crucial role in generating muscular contractions and bringing about a tremendous degree of focus and enhanced cognition.
11 Questions Answered
Attention is how we perceive the sensory world, focusing on certain inputs while filtering out others. People with ADHD struggle to hold this focused attention.
Impulse control is about limiting perception and putting blinders on to sensory events, which people with ADHD often struggle with, leading to high impulsivity.
People with ADHD can exhibit an incredible ability to focus intensely on things they genuinely enjoy or are intrigued by, even though they struggle to engage attention for mundane tasks.
People with ADHD often run late and procrastinate, underestimating how long tasks will take, though they can perceive time well if deadlines or consequences are severe.
Working memory is the ability to keep specific information online for short-term use (e.g., 10 seconds to a minute or two), which is often disrupted in individuals with ADHD, despite having good long-term memory.
Dopamine narrows visual and auditory focus, creating a 'cone' or 'tunnel' of attention, allowing individuals to direct their perception to specific environmental stimuli.
In people without ADHD, these networks are typically 'anti-correlated,' meaning when one is active, the other is less active, allowing for focused task engagement or rest.
According to the low dopamine hypothesis, they may be attempting to self-medicate, as these substances temporarily increase dopamine levels, which can improve focus and calmness.
Due to high neuroplasticity in childhood, early treatment with stimulants can help train frontal, task-related circuits to function appropriately, allowing children to learn how to focus in various contexts.
These drugs carry a high propensity for addiction and abuse, can cause sexual side effects due to vasoconstriction, and may lead to cardiovascular problems by increasing heart rate and constricting blood vessels.
The rapid turnover of context and infinite bits of information within a smartphone can induce a form of 'ADHD,' eroding natural attentional capacities and making it harder for the brain to maintain focus in the physical world.
14 Actionable Insights
1. Seek Professional ADHD Diagnosis
Obtain a clear and real diagnosis of ADHD from a psychiatrist, physician, or well-trained clinical psychologist, as self-diagnosis or diagnosing others can be misleading.
2. Limit Smartphone Use
Limit smartphone use to 60 minutes or less per day for adolescents and two hours or less per day for adults to maintain and improve focus capacity, as excessive use is thought to erode attentional abilities.
3. Consider Early ADHD Treatment
If a child is diagnosed with ADHD, consider early treatment with physician-prescribed medication to leverage high neuroplasticity in childhood (ages 3-12/13) and help frontal circuits develop appropriate functioning for focus.
4. Combine ADHD Meds with Behavior
If using prescription ADHD medications (e.g., Adderall, Ritalin), combine these treatments with behavioral exercises that actively engage the neural circuits for focus, with the potential goal of tapering off drugs once circuits are trained.
5. Practice Open Monitoring (Dilate Gaze)
Consciously practice dilating your gaze into panoramic vision (open monitoring) for 17 minutes in a single session, as this has been shown to significantly reduce attentional blinks and improve focus in a near-permanent way.
6. Fixation-Focused Training & Blinking
Engage in fixation-focused training by concentrating visual attention on a close object for a short period (e.g., 30-60 seconds), consciously controlling blinks, to enhance overall focus and improve time perception.
7. Physical Movement Before Focus
Before engaging in focus-demanding tasks, especially for children, perform a series of physical movements to release excess energy and enhance the ability to sit still and focus.
8. Consume Omega-3 DHA
Consume at least 300 milligrams of DHA daily from omega-3 fatty acids, as this threshold level has been shown to positively modulate systems for attention and focus.
9. Phosphatidylserine for Children’s ADHD
For children with ADHD, consider taking 200 milligrams of phosphatidylserine daily for two months, as it has been shown to reduce symptoms, with enhanced effects when combined with omega-3 fatty acids.
10. Alpha-GPC for Focus/Cognition
To enhance focus and cognition, consider supplementing with Alpha-GPC (typically 300-600mg, or up to 1200mg daily with doctor consultation), as it increases acetylcholine transmission.
11. L-Tyrosine with Extreme Caution
If considering L-tyrosine to increase dopamine for focus, approach with extreme caution due to tricky dosage (100-1200mg range) and potential side effects like euphoria or jitters, especially with underlying psychiatric or mood disorders.
12. Practice Non-Sleep Deep Rest (NSDR)
Incorporate Non-Sleep Deep Rest (NSDR) practices to offset negative effects of slight sleep deprivation and improve the ability to fall back asleep if waking during the night.
13. Use Red Light Therapy
Use medical-grade red light therapy devices (e.g., Juve) 3-4 times per week to improve muscle recovery, skin health, wound healing, reduce acne, pain, and inflammation, and enhance mitochondrial and visual function.
14. Supplement Omega-3 & D3+K2
Supplement with Omega-3 fish oil and Vitamin D3+K2 to support mood, brain health, heart health, and healthy hormone status.
4 Key Quotes
So dopamine and low levels of dopamine apparently are what's wrong in people with ADHD.

2 Protocols
Attentional Blink Reduction Training
Andrew Huberman- Consciously dilate your gaze into panoramic vision.
- Consciously contract your field of view.
- Practice this once for 17 minutes to significantly reduce attentional blinks.
Elementary School Visual Fixation-Focused Training
Andrew Huberman (describing a study)- Perform a series of physical movements to eliminate or move out some of the desire to move, thereby enhancing the ability to sit still.
- Focus visual attention on a relatively close object (e.g., one's hand) for about a minute.
- Repeat this for a few minutes each day, gradually looking at objects further out.
