Before You Treat the ADHD, the Dyslexia, the Memory Loss – Rule Out Anxiety.

Worry Loop
9:14 AM

Teacher just asked a question. Did she look at me?

9:15 AM

What if she calls on me. What if I get it wrong.

9:16 AM

Heart racing. I can feel it in my throat.

9:17 AM

What did she even ask? I missed it. Now I’m behind.

9:18 AM

Everyone can probably tell I’m panicking. I need to leave.

Four minutes of classroom time. Zero minutes of learning. The working memory has been entirely consumed by threat monitoring. The teacher will mark this student as inattentive, distracted, or struggling with the material. The teacher will be wrong on all three counts.

THE BASICS

“Anxiety disorders rank as the second foremost contributor to disability – adjusted life years globally – second only to depression. Yet anxiety remains under – screened in academic, occupational, and clinical settings, particularly when its symptoms are mistaken for primary attentional, cognitive, or developmental conditions.”

The Threat Loop

The amygdala fires faster, the prefrontal cortex regulates more slowly. The brain commits cognitive resources to threat that is not there – leaving less available for learning, working, and remembering.

Genetic + Environmental

Heritability runs around 30–40%. The rest is environmental – trauma, chronic stress, sleep deprivation, and (increasingly) the cognitive demands of modern adolescence and work.

Across the Lifespan

Anxiety presents differently at 6, 16, 36, and 76. The same underlying mechanism produces school refusal in childhood, panic attacks in young adulthood, burnout at work, and reversible cognitive confusion in older adults.

Highly Treatable

CBT shows large effect sizes in both children and adults. Medication helps where appropriate. Mindfulness, exercise, and sleep hygiene add meaningful gains. The hardest step is the first: knowing that what is happening has a name.

The Five – Domain Profile

MyMemoryMentor’s anxiety screener does not produce a single score. It produces a five – domain profile – because anxiety is rarely uniform. A learner may be severe in one domain and minimal in another, and the pattern matters more than the total. This is the architecture the screener report uses.

PS

Physical Symptoms

The body’s somatic – autonomic response – heart racing, dizziness, sweating, nausea, breath catching.

  • Heart pounding without exertion
  • Dizziness or feeling faint
  • Tight chest, shallow breathing
  • Sweating, hot flushes, nausea
TA

Thought Anxiety

Persistent, intrusive worry – particularly about future events, performance, and worst – case outcomes.

  • Uncontrollable worry about the future
  • “What if” loops that won’t quiet
  • Catastrophic thinking patterns
  • Rumination on past mistakes
SA

Social Anxiety

Performance and social situations trigger disproportionate fear – speaking up, group work, presentations.

  • Fear of judgement or embarrassment
  • Avoidance of group activities
  • Severe distress before presentations
  • Difficulty making or maintaining friendships
PF

 Panic & Fear

Acute episodes of heightened anxiety with both psychological and physical manifestations, often triggered by change.

  • Sudden panic attacks
  • Fear out of proportion to event
  • Distress at unexpected change
  • Anticipatory dread before triggers
BA

Behavioral Anxiety

Anxiety expressed through observable behaviour – restlessness, irritability, inability to settle. The domain most often mistaken for ADHD.

  • Restlessness, can’t sit still
  • Irritability and frustration
  • Pacing, fidgeting, leg bouncing
  • Difficulty relaxing or winding down
The Differential Diagnosis That Matters

Anxiety is the great cognitive imitator. Because chronic worry consumes working memory, hijacks attention, and produces visible restlessness, it looks like ADHD. Because it impairs reading fluency and recall under timed conditions, it looks like an SLD. Because it produces social withdrawal and rigidity, it looks like autism. Because it generates confusion and forgetfulness in older adults, it looks like early dementia. The research on each crossover is settled yet primary screening rarely tests anxiety first.

Condition Anxiety Mimics

Shared Surface Symptoms

What Actually Distinguishes Them

ADHD

Inattention, restlessness, distractibility, irritability, executive function failures, difficulty completing tasks, forgetfulness, fidgeting, “can’t sit still”

ADHD-related inattention is constant and present even during enjoyable activities. Anxiety-driven inattention is situational, triggered by specific worries, and the person is typically aware of their distraction – tense, guilty, hypervigilant.

Specific Learning Disabilities

Slow reading fluency, poor comprehension under time pressure, working memory failures, written expression collapse, mathematical anxiety, test underperformance versus classroom understanding

SLD difficulties are present even in low-stress, untimed conditions. Anxiety-driven academic failure improves dramatically when test conditions change. The 2025 Annals of Dyslexia review confirms test anxiety mediates the relationship between trait anxiety and academic performance independently of any underlying SLD.

Autism Spectrum

Social withdrawal, school refusal, sensory sensitivity, rigidity around routine, meltdowns at change, difficulty with group work, preference for solitude

Autistic social difference is consistent across the lifespan and present from early development. Anxiety-driven social avoidance has a clear onset, fluctuates with stress level, and the person typically wants social connection but cannot access it due to fear, not preference.

Depression

Low energy, poor concentration, sleep disturbance, social withdrawal, irritability, hopelessness, loss of interest in activities, fatigue

Depression centres on sadness, hopelessness, and pervasive low mood. Anxiety centres on fear, dread, and threat. They co-occur frequently – Lancet 2024 places comorbidity around 50% – but the dominant emotional tone differs and matters for treatment selection.

Early Dementia / MCI

Forgetfulness, confusion in new environments, difficulty multitasking, word-finding problems, withdrawal from social activities, slowed processing, “cognitive fog”

Dementia produces progressive, day-to-day cognitive decline that does not fluctuate with mood. Anxiety-driven cognitive confusion fluctuates dramatically with stress level and is reversible. NHATS Round 12 data shows pain, low community cohesion, and depression triggered the anxiety in 51% of older adults flagged with cognitive impairment.

Workplace Burnout

Exhaustion, irritability, cognitive fatigue, depersonalisation, missed deadlines, decision avoidance, late-night ruminating about work, Sunday-evening dread

Burnout is environmentally driven and improves with rest and reduced workload. Anxiety persists even when external demands ease. 61% of workplace caregivers in the 2024 China cohort study reported moderate-to-severe anxiety distinct from their burnout scores.

The research is clear and converging. Marsh et al. (Florida State, 2025) demonstrated that domain-general anxiety directly impairs phonological short-term memory in children regardless of whether ADHD is present – cmeaning anxiety produces working memory deficits that look identical to ADHD-driven ones on standardised cognitive testing. Eysenck’s cognitive interference theory, validated in five decades of replication, shows that worry and intrusive thoughts compete for the same working memory resources required for reading, calculation, and learning. The implication is operational: screening for anxiety first, before assuming a primary cognitive or developmental condition, is the single most cost-effective diagnostic step a parent, educator, or clinician can take.

Prevalence

Anxiety is the most common mental health condition globally – and the most rapidly rising in young populations. Yet under 30% of those experiencing it receive anytreatment, and a substantial fraction are misdiagnosed before reaching the right one.

global prevalence of anxiety disorders in children aged 10–14

global prevalence in adolescents aged 15 – 19 – rising sharply post-2019

regional prevalence in Australia among adults – among the highest worldwide

co-occurrence with depression in adults -the most common comorbid pair

Across the Lifespan

Anxiety is not a single-stage condition. It changes face across childhood, adolescence, adulthood, and older age – producing the same underlying disruption through entirely different surface symptoms. Identification looks different at each stage. The screening signal does not.

Children – How Anxiety Hides in School

Childhood anxiety rarely arrives saying its own name. It comes as stomach aches on school mornings, tears before homework, refusal to attend birthday parties, separation distress that does not fade with age, and a child who “knows the material but freezes on the test.” Parents and teachers see behaviour. The anxiety underneath stays invisible.

Physical complaints on school mornings — stomach aches, headaches, nausea

Tearfulness or panic before tests, presentations, or new activities

Excessive worry about parents’ safety, separations, sleepovers

Avoidance of activities other children enjoy

“Knows it at home, freezes at school” — performance gap

Sleep difficulties, frequent nightmares, bed-wetting regression

Perfectionism, intolerance of mistakes, eraser-shredded homework

Reported Anxiety Markers in Children

Somatic complaints (stomach, head)74%
Test or performance fear68%
Sleep disturbance63%
Separation distress52%

Teens — When School Refusal Begins

Adolescent anxiety is the fastest-growing mental health crisis of the decade. The 2024 Frontiers in Psychiatry global burden review confirmed a 52% rise in incidence from 1990 to 2021, accelerating post-2019. By 15–19, prevalence reaches 5.5% globally – and bullying victimisation has emerged as a major modifiable risk factor.

School refusal – physical inability to enter the building

Persistent rumination, racing thoughts, “what if” loops

Social withdrawal from previously enjoyed friendships

Sudden grade decline without identifiable academic cause

Panic attacks – racing heart, breathing difficulty, dread

Compulsive phone or social media use as escape, not connection

Self-harm or disordered eating as regulation strategies

Adolescent boys may show through anger, withdrawal, substance use

Adolescent Anxiety Self-Reported Impact

School performance decline78%
Social withdrawal71%
Sleep deprivation83%
Co-occurring depression50%

Adults — The Cost in the Workplace

Adult anxiety reshapes careers without anyone noticing. It produces Sunday-evening dread, the inability to read long documents, the meeting where everything was understood but nothing could be said, the missed promotion routed around fear of leadership exposure. Adults with anxiety are often labelled cautious, perfectionist, or simply “not management material.” The cost compounds across decades.

Sunday-evening dread, Monday-morning panic

Avoidance of meetings, presentations, public visibility

Procrastination on tasks that produce anxiety, not on all tasks

Email inbox dread – opening messages becomes a daily battle

Career paths unconsciously routed around exposure to fear triggers

Insomnia, particularly mid-night waking with racing thoughts

Decision fatigue and analysis paralysis on routine choices

“High-functioning” anxiety hiding behind perfectionism and over-work

Adult Anxiety Workplace Impact

Sleep / racing thoughts at night8%
Workplace avoidance behaviour69%
Decision fatigue / paralysis76%
Burnout overlap (often misdiagnosed)64%

Older Adults — When Anxiety Looks Like Dementia

Older-adult anxiety is the most misdiagnosed presentation of all. NHATS Round 12 data shows that anxiety in older adults produces forgetfulness, confusion, and cognitive fog that fluctuate with stress level — meaning they reverse with treatment. Dementia does not reverse. Yet many older adults are referred straight to dementia evaluation, when an anxiety screen could have resolved the case.

Cognitive fog that fluctuates with stress, sleep, and medication

Confusion in new environments – supermarkets, social events

Persistent worry about medications, finances, family safety

Withdrawal from social activities once enjoyed

Sleep disturbance with mid-night ruminating

Physical complaints with no medical explanation

Suspected dementia that fluctuates — better days, worse days

Caregiver burnout creating compounding anxiety on top of grief

Older Adult Anxiety Patterns

Initially misdiagnosed as dementia / MCI54%
Co-occurring pain or chronic illness67%
Co-occurring depression61%
Social isolation contributing72%
The Mechanism

Working Memory Hijack

Eysenck’s cognitive interference theory, replicated for five decades, shows that worry and intrusive thoughts compete for the same phonological short-term memory resources required for reading, mental calculation, and learning. Marsh et al. (2025) confirmed this effect operates independently of ADHD – meaning anxiety alone produces working memory deficits that look identical to ADHD on cognitive testing.

The workspace, occupied by worry

Attentional Bias Toward Threat

The anxious brain preferentially scans for danger. Attention locks onto threat-relevant cues (a teacher’s frown, a vague email, an unexpected phone call) at the expense of task-relevant ones. From outside, this looks like distractibility. From inside, the attention is intensely focused – just on the wrong thing. ADHD’s distraction is content-neutral. Anxiety’s is content-specific.

 Focus on the wrong signal

Autonomic Load on Cognition

Sustained sympathetic nervous system activation – racing heart, shallow breathing, muscle tension – diverts physiological resources to threat preparation. The prefrontal cortex, the region governing complex reasoning and impulse control, receives less. Decisions slow, mistakes rise, and the appearance of cognitive impairment emerges. The cognition was never the problem.

The Comprehensive Assessment
01

Number Sense

Foundational understanding of quantities, order, and numerical relationships.

→ Typically intact in anxiety – strong here with timed weakness elsewhere is highly signalling

02

Math Facts & Fluency

Automatic retrieval of basic operations – the system anxiety hijacks first.

→ Where math anxiety produces its largest measurable effect

03

Visual Processing & Subitising

Visual-spatial and pattern skills for quantity perception.

→ Generally preserved in anxiety, differentiating it from dyscalculia

04

Working Memory

Capacity to hold and manipulate numbers during multi – step problems.

→ The exact system Eysenck’s interference theory identifies as anxiety’s primary cognitive cost

05

Math Reasoning

Application of concepts in untimed word problems and conceptual tasks.

→ Strong reasoning paired with collapsed fluency is the anxiety signature

06

Rapid Automatised Naming

Speed of visual-verbal association under timed pressure.

→ Anxiety-driven RAN deficits are reversible; SLD-driven deficits are not

The Diagnostic Power of a Cognitive Profile

The anxious brain produces a recognisable pattern on cognitive assessment: strong reasoning under low-pressure conditions, collapse under timed conditions; intact conceptual understanding paired with broken procedural fluency; visual processing intact, working memory consumed by worry. This profile is the inverse of an SLD profile, which shows consistent difficulty across conditions.

EMA captures exactly this distinction across number sense, math facts and fluency, visual processing and subitising, working memory, math reasoning, and rapid automatised naming. When EMA results show high conceptual scores paired with timed-condition collapse and RAN deficits, anxiety becomes the leading hypothesis – and a referred-out clinical confirmation becomes the right next step. The screener flags the signal. EMA confirms the pattern. The right intervention follows.

Support

The strongest evidence base in mental health. CBT for anxiety produces large effect sizes in both children and adults, with gains maintained at 12 – month follow-up. The first-line intervention for almost every anxiety presentation.

Avoidance reinforces anxiety; structured, gradual exposure to feared situations rewires the threat response. Particularly effective for social anxiety, specific phobias, and panic disorder.

Breath work, progressive muscle relaxation, mindful walking, brief meditation. These do not eliminate anxiety – they teach the nervous system to recover faster from spikes, which dramatically reduces functional impact.

SSRIs are first-line for moderate-to-severe presentations. Short-term benzodiazepines have a place in acute crisis but require careful prescribing. Always clinician-led; never replaces psychological intervention.

Predictable routines, advance notice of change, alternative presentation formats, quiet regulation spaces, exam accommodations. Recognised under IDEA, the Equality Act 2010, and ADA when functional impairment is documented.

Not cures, but powerful amplifiers. Consistent sleep, daily aerobic movement, reduced caffeine, and managed alcohol use all materially reduce baseline anxiety. Often the first interventions to try, alongside professional support.

FAQs

Anxiety is a chronic activation of the body’s threat-response system. Where momentary worry helps performance, sustained anxiety hijacks attention, working memory, sleep, and decision-making -producing functional impairment in school, work, relationships, and daily life. Recognised in DSM-5 and ICD-11 as a family of disorders (Generalised Anxiety Disorder, Panic Disorder, Social Anxiety Disorder, Specific Phobias, OCD, PTSD), anxiety is the most common mental health condition globally.

Source: DSM-5-TR; ICD-11, World Health Organization; WHO Mental Health 2024

Yes -extensively. Anxiety produces restlessness, distractibility, working memory failures, irritability, and difficulty completing tasks. All of these overlap directly with ADHD’s diagnostic criteria. The 2025 Florida State University study (Marsh et al.) confirmed that domain-general anxiety impairs phonological short-term memory regardless of ADHD status -meaning anxiety alone can produce ADHD-pattern cognitive deficits. The key distinguishing feature: ADHD inattention is constant and present in enjoyable activities; anxiety inattention is situational and accompanied by tension, hypervigilance, and awareness of the distraction.

Source: Marsh et al. 2025 (Frontiers in Psychiatry); ADHD Evidence Project 2025; Panorama Psychology 2024

Yes -significantly. Eysenck’s cognitive interference theory, replicated for five decades, shows that worry and intrusive thoughts compete for the same working memory resources required for reading, mental calculation, and complex reasoning. A bright student with chronic anxiety can pass IQ tests in low-pressure conditions while progressively losing ground on timed, evaluative tasks. The 2025 Annals of Dyslexia study confirmed that test anxiety mediates the relationship between trait anxiety and academic performance independent of any underlying SLD -meaning anxiety produces SLD-pattern academic failure without an actual learning disability.

Globally, anxiety disorders affect approximately 4.05% of the population -around 301 million people. In children aged 10–14, prevalence is 4.4% globally; in adolescents 15–19, it rises to 5.5%. Female prevalence is consistently higher than male across the lifespan (32.7% vs 24.4% in the US, 37.1% vs 29.9% in the UK). Australia reports 17% adult prevalence -among the highest worldwide. Post-pandemic, 28% of U.S. adults report anxiety symptoms.

Burnout is environmentally driven and resolves with reduced workload and rest. Anxiety persists even when external demands ease. The two frequently co-occur -a 2024 China cohort study found 61% of workplace caregivers reported moderate-to-severe anxiety distinct from their burnout scores. The clinical implication: treating burnout (rest, time off, workload reduction) without addressing underlying anxiety produces a temporary improvement followed by recurrence. Both need attention if both are present.

Source: Zhang and Ji, 2024 (China caregiver cohort); WHO occupational mental health guidance

Yes -and frequently does. NHATS Round 12 data showed that pain, depression, and chronic stress trigger anxiety in 51% of older adults flagged with possible cognitive impairment. Anxiety-driven confusion is reversible: it fluctuates with stress level, sleep quality, and medication management. Dementia-driven decline is progressive and does not fluctuate. The clinical implication: anxiety screening should precede dementia evaluation in older adults presenting with cognitive concerns, because treating the anxiety often resolves the apparent dementia. Missing this step can lead to years of incorrect intervention.

MMM’s anxiety screener produces a five-domain profile aligned with clinical practice: Physical Symptoms (somatic-autonomic response), Thought Anxiety (intrusive worry), Social Anxiety (performance and social fear), Panic & Fear (acute episodes and reactivity to change), and Behavioral Anxiety (restlessness, irritability, observable manifestations). The screener generates plain-language interpretations, severity indicators by domain, and a clinical overview that flags differential diagnostic considerations -including the anxiety-ADHD overlap that the sample report explicitly addresses.

Source: MyMemoryMentor anxiety screener clinical framework; DSM-5-TR alignment

Yes. Anxiety is recognised under U.S. IDEA, the ADA, the UK Equality Act 2010, and equivalent legislation in most jurisdictions, where it produces functional impairment. Recognised educational accommodations include extra time on tests, quiet test settings, alternative presentation formats, scheduled breaks, and access to support staff. Workplace accommodations cover flexible scheduling, written rather than verbal communication options, structured advance notice of change, and reasonable adjustments to high-anxiety task formats. A formal assessment typically supports access to these protections.
