Largely, yes. Twin studies put ADHD's average heritability at about 74%, among the highest in psychiatry. Genes are not the whole story, though. A child's genetic tendencies can shape how caregivers respond, and early environment and chronic stress can further shape how attention and executive function are regulated over time.

Can too much screen time cause ADHD?

Current evidence does not show that it does. Fast, high-reward digital environments can condition attention patterns that resemble ADHD, and the two can coexist. Developmental history, not current symptoms alone, helps tell them apart.

Can ADHD be mistaken for anxiety?

Yes, particularly in women and girls. ADHD traits can be overshadowed by more prominent anxiety or depression, and the mood diagnosis may then be treated as the whole picture. Anxiety can also play a compensatory role. In one longitudinal study of youth with ADHD, higher anxiety predicted better inhibitory control over time, which may help hide underlying difficulties.

Why are women diagnosed with ADHD later than men?

In a Swedish registry study of more than 85,000 people with ADHD, women were diagnosed nearly four years later than men, despite extensive prior contact with mental health services. Women more often present with less outwardly disruptive symptoms. Symptoms may also shift across the menstrual cycle, so a single assessment can miss the full pattern.

Are there racial disparities in ADHD diagnosis?

Yes. In an analysis of US health records, white patients were about 26% more likely than Black patients to receive an ADHD diagnosis, and Black women were the least likely of any group to be diagnosed. Research on clinician bias suggests comparable behavior is more often read as a conduct problem in children of color, while white children are more likely to receive an anxiety or mood-related diagnosis.

A Holistic Look at ADHD | Part 1 of 3

Where it stands, where it's going, and who gets missed in between

By Shaun Menashe, LAc, MTOM, Dipl. O.M. | Golden Mean Acupuncture, Los Angeles

For education only, not medical advice. Golden Mean Acupuncture does not diagnose ADHD; see the full note at the end.

In my Los Angeles practice, which draws from a health-engaged patient population, about one in five patients note some form of neurodivergence on their chart, well above the current national adult ADHD diagnosis rate of roughly 6% (Staley et al., 2024). Some arrive with a longstanding diagnosis while others are neurodivergent-curious or self-diagnosed, spurred by the wave of ADHD content on TikTok and the algorithms surfacing self-help narratives and communal recognition.

As patients and clinicians have long noted, the ADHD diagnosis itself is often the tip of a larger physiological and emotional iceberg. Modern research increasingly connects ADHD to digestive capacity, sleep quality and duration, stress tolerance and emotional self-regulation, and chronic pain. Some of these patterns carry their own diagnoses, including dysautonomia and POTS, autoimmune disease, and PTSD. People with ADHD also show elevated rates of anxiety, depression, and substance use disorders (Faraone et al., 2021). Whether these symptoms and diagnoses are comorbid with ADHD, exacerbate it, or stem from the same underlying nervous system dysregulation has yet to be established.

Approaching these systems as interconnected, even provisionally, may help explain diagnostic gaps. This first installment of a three-part series takes on three questions: whether circumstance, environment, and population-level characteristics shape who gets diagnosed and who doesn't, whether attention difficulties can be learned rather than innate, and whether ADHD can adapt into disguise, to read as anxiety or another condition entirely. Part 2 turns to autonomic, hypermobility, immune, and gut pathologies that often travel alongside ADHD, and Part 3 covers holistic and integrated approaches to ADHD and those systemic patterns.

Key Takeaways

The Diagnosis Gap: ADHD is often diagnosed later, less frequently, or misread entirely in women and people of color. The gap likely reflects both limited screening tools built around a narrow picture of ADHD and implicit clinician bias.
Self-Report Meets Social Media: Because ADHD diagnosis relies on self-report rather than lab or imaging data, it is unusually sensitive to how patients frame their own experience. Research links heavier viewing of ADHD-related TikTok content to viewers' higher estimates of the condition's prevalence and burden.
The Genetic Link: ADHD is among the most heritable conditions in psychiatry. Genetic risk for ADHD is linked to household chaos and parenting.
Context Changes the Picture: ADHD symptoms fluctuate meaningfully across settings, times of day, and levels of stimulation. A demanding or genuinely interesting environment can hide difficulties that surface in repetitive, low-stimulation settings.
Screen Habits or ADHD: Attention patterns shaped by fast, high-reward digital environments can resemble ADHD on the surface. The two can also coexist, and separating them requires looking at developmental history, not just present-day symptoms.
Timing Matters: ADHD symptoms can worsen in the luteal and premenstrual phases of the menstrual cycle, so a single assessment may miss the full pattern and affect whether ADHD is recognized at all.

ADHD and the Diagnosis Gap

The DSM-5 recognizes three ADHD presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. This marks an important and deliberate change from the older "subtype" language, allowing for shifts in traits across a given lifespan. The inattentive presentation involves difficulty with sustained attention, organization, and follow-through, alongside little outward hyperactivity, which makes it considerably easier to overlook than the more visibly disruptive hyperactive-impulsive presentation. Presentations vary greatly based on environmental, socio-cultural, economic, and developmental factors. Traits can shift with context, age, and experience. In some individuals, traits become clear only in moments of stress or during certain tasks.

While ADHD trait variability justifies broad diagnostic criteria, clinical assessment lacks the objective laboratory or imaging data common to other medical specialties. Instead, evaluations often lean on brief rating scales, which can flag symptoms but cannot establish a diagnosis on their own (Faraone et al., 2021). Comprehensive cognitive testing yields similar blind spots. Diagnostic batteries integrating tests across multiple cognitive domains correctly identify only about two in three adults with confirmed ADHD, with approximately one in ten performing within normal ranges across every measure (Mostert et al., 2015).

Self-report questionnaires are inherently sensitive to framing effects and often capture a learned interpretation of distress. Recent research evaluating ADHD-related content on TikTok found that the majority of high-engagement videos presented non-specific symptoms shared broadly with anxiety, depressive disorders, or routine cognitive fatigue, while higher consumption was associated with higher estimates of ADHD prevalence and perceived burden (Karasavva et al., 2025). As a result, standardized rating scales may capture a patient's newly acquired narrative alongside their own unprompted experience.

Diagnostic Disparities by Sex and Race

Diagnostic vulnerability also compounds across biological sex. A Swedish registry study of more than 85,000 people with ADHD found women were diagnosed nearly four years later than men, despite having had extensive prior contact with the mental health system (Skoglund et al., 2024). Girls and women more often present with less outwardly disruptive symptoms, and key ADHD traits may be overshadowed by more prominent feelings of anxiety or depression. A mood disorder diagnosis can overlook the underlying ADHD architecture.

In biological women with ADHD, symptoms can also shift across the menstrual cycle, often worsening during the luteal and premenstrual phases (Wynchank et al., 2026). A single ADHD evaluation risks capturing a temporary high or low point, missing both an underlying baseline and an accurate diagnosis (Wynchank et al., 2025). Part 2 looks more closely at the hormonal patterns behind this.

Diagnostic disparities run along both sex and racial lines. In an analysis of US health records covering 849,281 ADHD patients, white patients were about 26% more likely than Black patients to receive an ADHD diagnosis, with Black women the least likely of any group to be diagnosed (Shalaby et al., 2024). The same study found conduct disorder (aggression, property destruction, theft, or serious rule violations) was diagnosed significantly more often in Black patients. Conduct disorder places dysregulation in a disruptive-behavior frame rather than a neurodevelopmental one, with stronger links to the juvenile justice system (Yampolskaya and Chuang, 2012), while an ADHD diagnosis establishes a clinical framework of medical accommodation and support. Implicit bias may lead clinicians to read comparable behavior as disruptive conduct in children of color, while white children showing the same symptoms are more likely to receive an anxiety or mood-related diagnosis (Fadus et al., 2020; Shalaby et al., 2024).

ADHD, Heritability, and Context

Developmental Context

ADHD is one of the most heritable conditions in psychiatry. In a Swedish sibling study spanning more than 4.4 million individuals, ADHD had the highest sibling-based heritability of eight major psychiatric disorders examined, ahead of schizophrenia, bipolar disorder, and autism spectrum disorder (Pettersson et al., 2019). A synthesis of 37 twin studies put the average heritability at 74%, with estimates for categorically diagnosed ADHD specifically running as high as 77 to 88% (Faraone and Larsson, 2019).

ADHD's high genetic contribution points to an underlying biology, yet whether that biology represents a single neurodevelopmental profile or several distinct pathways converging on the same diagnostic pattern remains an open question. Genes may set the baseline capacity for attention and executive function, possibly through more than one of those pathways. Early environment and chronic stress can further shape how those systems are regulated across the lifespan.

Large population studies have found associations between ADHD symptoms and factors such as family conflict, health conditions around pregnancy and birth, and breastfeeding duration. Families share genes, living environments, socioeconomic conditions, and health histories, among other confounding factors, making it difficult to isolate whether a given exposure itself affects ADHD presentation.

Sibling-comparison studies provide a critical control by evaluating siblings who share familial genetics and household backgrounds but differ in specific exposures. When researchers applied the design to proposed environmental risks, several longstanding associations weakened substantially. Maternal smoking during pregnancy, widely cited as a primary environmental contributor, did not hold up in a large Norwegian sibling-comparison study. The association appeared to reflect shared familial confounding rather than a direct intrauterine effect (Gustavson et al., 2017). The reported link with prenatal acetaminophen exposure weakened substantially under the same comparison (Gustavson et al., 2021), and the apparent behavioral benefits attributed to breastfeeding duration were similarly lessened (Colen and Ramey, 2014).

It may be that early biological exposures and adverse experiences shape human development significantly without specifically producing the ADHD pattern of dysregulation. A 2022 meta-analysis of 70 studies involving nearly four million participants found that exposure to adverse childhood experiences was associated with approximately 1.7 times the odds of ADHD (Zhang et al., 2022). Yet the same broad category of adversity is associated with a wide range of later psychological and physiological conditions, raising a deeper question: what determines which pattern of dysregulation?

A child's genetic tendencies can influence their caregiving environment. An impulsive, restless child may elicit greater parental frustration and less consistent structure, which may in turn reinforce those behaviors. Behavioral geneticists call the first half of this loop, genes shaping environmental responses, evocative gene-environment correlation. Using ADHD polygenic risk scores (a measure combining the small effects of thousands of genetic variants into a single estimate of genetic liability) in nearly 2,000 children from the E-Risk longitudinal twin study, researchers found that children's genetic liability for ADHD was associated with greater household chaos even after accounting for maternal genetic risk (Agnew-Blais et al., 2022). The authors also found that household chaos was independently associated with ADHD symptoms, while sensitivity analyses suggested that genetic and environmental influences were substantially intertwined.

In a study of 803 youth, higher ADHD polygenic risk was associated with more ADHD symptoms, which in turn were associated with lower parental involvement, poorer supervision and monitoring, and more inconsistent discipline (de la Paz et al., 2023).

The biological impact of a given stressor varies widely between individuals. Baseline physiology and developmental history interact continuously with environment, so comparable exposures can produce divergent clinical trajectories. Despite their limitations, these studies outline an interconnected framework in which genes and environment shape each other over time.

Regulated External Conditions, Regulated Internal States

ADHD symptoms fluctuate by time of day and setting (Barkley, 2015), often becoming minimal or absent when an individual is closely supervised, in a novel environment, receiving frequent rewards, or interacting one-on-one (American Psychiatric Association, 2013). This variability may reflect a core difficulty directing executive control toward activities that lack intrinsic reward (Barkley, 2015).

A study following 125 young adults originally diagnosed with ADHD as children found that many participants described their symptoms as context dependent, improving in environments that were stressful, novel, fast paced, or genuinely interesting, and worsening in settings that were low energy, repetitive, or understimulating (Lasky et al., 2016). Patients often learn to circumvent these limitations by gravitating toward positions and tasks where the same traits that impair performance elsewhere can become an advantage (Lasky et al., 2016).

Compensatory adaptation also operates internally. A longitudinal study in youth with ADHD found that higher anxiety symptoms predicted better inhibitory control over time, suggesting that internalized worry can function as a compensatory driver (Slomowitz et al., 2023). Over years of contextual trial and error, individuals build out additional strategies across organizational, physical, social, attentional, and psychopharmacological (self-medicating) domains (Canela et al., 2017). Together, these self-taught workarounds, internalized pressures, and favorable environments can be effective enough to mask underlying difficulties from both patient and clinician for years.

Learned Patterns Can Mimic ADHD

Not every attention problem is ADHD. The reward system that shapes attention operates in every brain, not just in ADHD: dopamine neurons respond to rewards and to the gap between what we expect and what actually happens. This reward-prediction signal is one way novelty, anticipation, and immediate feedback shape behavior (Schultz, 2024).

Modern digital environments make heavy use of these principles. Notifications, scrolling feeds, rapidly changing content, and unpredictable rewards continually introduce new opportunities for attention to shift. Over time, a person can become accustomed to an environment in which attention is repeatedly interrupted and rewarded with something new. Ordinary tasks that offer slower or less immediate feedback may then feel comparatively unrewarding, contributing to difficulty sustaining effort, task switching, or resisting distraction. An attention pattern reinforced by an environment like this can resemble ADHD on the surface.

Conditioned attention habits and lifelong ADHD can look nearly identical on a present-day symptom screener, and the two can coexist. Screen-conditioned distractibility can be misread as ADHD, while lifelong ADHD can be dismissed as a product of modern habits. Separating them requires examining developmental history, chronicity, and consistency across settings rather than relying on current symptom counts alone.

Diagnosis Beyond Cognitive Symptoms

A diagnosis built largely on self-report sees mostly what sits above the waterline. Below it, ADHD has been linked to measurable differences in autonomic function (Bellato et al., 2020), joint hypermobility (Csecs et al., 2022), and immune disorders (Faraone et al., 2021), findings that may offer evidence beyond cognitive symptoms alone. Part 2 explores these systems, along with emotional regulation, hormonal cycles, and the gut, and the debate over whether they cause, follow, or simply travel alongside ADHD.
