In this episode of the Huberman Lab podcast, Huberman explains the neuroscience behind ADHD, describing how disrupted neural circuits and dopamine levels affect focus and attention. He explores how ADHD manifests in daily life, from difficulties with routine tasks to the ability to intensely focus on topics of high interest, and discusses how the condition impacts time perception and task management.
The episode covers both pharmaceutical and non-pharmaceutical approaches to managing ADHD symptoms and improving focus. Huberman details how common ADHD medications work in the brain, and presents research-backed alternatives including specific supplement combinations and visual attention exercises. He also addresses the role of smartphone use in attention management and provides practical guidelines for screen time limits.

Andrew Huberman explains that ADHD involves disrupted neural circuits, particularly affecting the brain's default mode and task networks. In typical brains, these networks operate in a seesaw fashion - when one is active, the other is quiet. However, in ADHD brains, this coordination is disrupted, leading to attention and focus difficulties.
Huberman notes that [restricted term] plays a crucial role as a conductor, helping maintain proper network coordination. Low [restricted term] levels in ADHD can lead to uncontrolled neural firing, making it difficult to maintain focus on specific tasks.
People with ADHD often struggle with routine tasks while demonstrating remarkable ability to focus intensely on topics of high interest - a phenomenon known as 'hyperfocus.' Huberman suggests that rather than lacking focus entirely, individuals with ADHD experience frequent attentional "blinks" when engaging with less stimulating topics.
The condition also affects time perception, with individuals often underestimating how long tasks will take. This manifests as chronic tardiness and procrastination, particularly when immediate consequences aren't present.
Common ADHD medications like [restricted term], [restricted term], and [restricted term] work by increasing [restricted term] levels in the brain. Huberman explains that these medications help children with ADHD learn what focus feels like by activating their task-related networks appropriately. However, he emphasizes the need for caution due to these drugs' similarity to recreational substances and their potential for abuse, particularly in younger populations.
Research suggests several non-pharmaceutical approaches to managing ADHD symptoms. These include supplementation with DHA omega-3s (minimum 300mg daily) and phosphatidylserine (200mg daily), which show particular promise when used together.
Huberman describes a technique involving focused visual attention exercises that can enhance focus abilities, potentially with lasting effects. He also emphasizes the importance of limiting smartphone use, recommending no more than 60 minutes daily for adolescents and two hours for adults to preserve attention capabilities.
1-Page Summary
The complexities of ADHD involve disrupted neural circuits and neurochemical imbalances, particularly involving [restricted term] and acetylcholine, which regulate focus, attention, and time perception.
Andrew Huberman explains that in ADHD, the brain’s default mode network and task networks—which play key roles in attention and focus—do not function properly. In non-ADHD brains, these networks are synchronized in such a way that they are anti-correlated, working in seesaw fashion. When one is active, the other is quiet. However, in those with ADHD, this anti-correlation is absent, leading to impairments in attention and focus. People with ADHD typically have difficulty maintaining attention to their senses and holding short-term information in their minds.
The default mode network is active during idle times, and task networks are goal-oriented, active when directing our behavior. In individuals with ADHD, instead of being anti-correlated, these networks are improperly coordinated, disrupting the ability to focus. When conditions improve in individuals with ADHD—whether through treatment or naturally over time—the networks begin to exhibit typical anti-correlation once again.
[restricted term], a neuromodulator, is crucial for creating a heightened state of focus. It narrows auditory and visual attention, acting like a conductor to ensure the default mode network and task network remain anti-correlated. Disruptions in the [restricted term] system in people with ADHD mean these networks are not effectively managed, causing problems with attention.

The Neurobiology and Neurochemistry of ADHD
The challenges and nuances of Attention Deficit Hyperactivity Disorder (ADHD) are complex, with individuals often struggling to focus on routine tasks yet capable of high levels of concentration on subjects of high interest, alongside issues with impulsive behavior, emotional regulation, and time management.
For people with ADHD, engaging in mundane activities or tasks that do not captivate their interest is notably challenging. Their attention often fluctuates dependent on the level of personal interest in a task at hand.
Individuals with ADHD are known to experience 'hyperfocus,' a state of intense concentration on activities they find highly stimulating or rewarding. This contradicts the common misconception that they are simply unable to focus at all. Huberman brings forth the hypothesis that those with ADHD do not lack focus inherently but rather experience frequent attentional blinks when engaging with less intriguing topics, while being able to deeply immerse themselves in matters of high interest.
Individuals with ADHD often exhibit behaviors associated with poor attention span, distractibility, impulsivity, and a heightened level of emotionality. These traits include an impulsive nature, an e ...
Symptomology and Challenges of ADHD
Andrew Huberman discusses the prominent medications for ADHD treatment and the concerns surrounding their potential for abuse and adverse effects, particularly in children.
Huberman explains that common ADHD drugs like [restricted term], [restricted term], and [restricted term] are designed to elevate [restricted term] levels, aiding the brain networks responsible for task-directed behaviors. When children with ADHD take these stimulants, their forebrain task-related network becomes more active at appropriate times, which helps them learn what focus feels like and how to maintain a focused state.
Classic drugs like [restricted term] ([restricted term]), [restricted term], [restricted term], and [restricted term] treat ADHD by boosting levels of [restricted term] and [restricted term] in the brain. Huberman notes that [restricted term] and [restricted term], unlike [restricted term] and [restricted term], are weak [restricted term] reuptake inhibitors, which is their method for increasing [restricted term].
Anecdotal evidence shows that people with ADHD may self-medicate with recreational substances or lawful stimulants, such as cigarettes and coffee, that also stimulate [restricted term] production. However, Huberman stresses that there is a striking resemblance between pharmaceutical stimulants for ADHD and recreational drugs like cocaine and ...
Pharmaceutical Treatments For Adhd
Recent studies suggest that the consumption of omega-3 fatty acids, particularly DHA, can significantly improve attention and focus.
Research indicates a minimum of 300 milligrams daily of DHA is vital for the attentional effects of omega-3 fatty acids. Furthermore, when phosphatidylserine is taken for two months at a dose of 200 milligrams per day, it reduces symptoms of ADHD in children. These effects are further enhanced by the consumption of omega-3 fatty acids, suggesting a synergistic relationship between the two supplements.
Huberman describes a tool supported by research that can enhance one's ability to focus and decrease attentional blinks in just a single session, potentially improving focus abilities permanently. This technique involves focusing visual attention on a close object for about a minute each day, which requires effort. To reduce restlessness and enhance the ability to sit still, physical movements are performed before this visual focus training. Huberman elaborates that controlling blinks through exercise of the eyelids helps regulate information input into the nervous system and process it over time.
Smartphones, although captivating, present rapid context changes that can disrupt our ability to focus. Huberman notes that constant interact ...
