ADHD Is Not What You Think It Is

Attention Deficit Hyperactivity Disorder is one of the most misunderstood conditions in the world. The name itself is misleading - ADHD isn't really about a deficit of attention. It's about the brain's inability to regulate attention consistently.

💡A Better Name

Many researchers argue ADHD should be called "Executive Function Developmental Delay" or "Variable Attention Stimulus Trait." The current name emphasises behaviour rather than neurology, leading to decades of misunderstanding.

People with ADHD can hyperfocus for hours on something that interests them while struggling to spend five minutes on something that doesn't. The problem isn't attention - it's the brain's dopamine-driven reward system that determines where attention goes.

The Three Types of ADHD

ADHD presents in three distinct ways, and understanding which type you or someone you know has can change everything about how you approach management.

💭

Inattentive Type

The quiet daydreamer. Struggles with focus, organisation, and follow-through. Often missed because there's no disruptive behaviour. Previously called ADD.

Hyperactive-Impulsive Type

The stereotypical presentation. Restlessness, fidgeting, talking excessively, and acting without thinking. More commonly diagnosed in childhood.

🔄

Combined Type

The most common presentation. A mix of both inattentive and hyperactive-impulsive symptoms. Symptoms may shift over time and with age.

🌱Hyperactivity Changes with Age

In adults, physical hyperactivity often transforms into internal restlessness - racing thoughts, difficulty relaxing, feeling driven by a motor that won't switch off. You might not bounce off walls, but your mind never stops.

Core ADHD Symptoms in Adults

Adult ADHD symptoms look different from the textbook descriptions written for children. Here's what it actually feels like:

Attention and Focus

Inattention Symptoms

0/8 complete
  • Zoning out during conversations even when you care about the topic
  • Starting multiple projects but finishing none of them
  • Losing things constantly - keys, phone, wallet, important documents
  • Difficulty following instructions with multiple steps
  • Making careless mistakes in work despite knowing the material
  • Avoiding tasks that require sustained mental effort
  • Forgetting appointments, deadlines, and commitments
  • Getting distracted by background noise, movement, or your own thoughts

Hyperactivity and Impulsivity

Hyperactive-Impulsive Symptoms

0/8 complete
  • Fidgeting, tapping, or inability to sit still in meetings
  • Talking excessively or interrupting others mid-sentence
  • Feeling restless or 'on edge' even during leisure time
  • Making impulsive purchases, decisions, or comments
  • Difficulty waiting your turn in queues or conversations
  • Taking on too many commitments because you can't say no in the moment
  • Needing to stay busy or feeling uncomfortable with silence
  • Emotional outbursts that feel disproportionate to the situation

The Hidden Symptoms Nobody Talks About

Beyond the clinical criteria, ADHD brings a host of symptoms that rarely make it into diagnostic manuals but profoundly affect daily life.

💔

Rejection Sensitive Dysphoria

Intense emotional pain from perceived rejection or criticism. A brief comment can send you spiralling for hours. Not just 'being sensitive' - it's neurological.

Time Blindness

Genuine difficulty perceiving time passing. Five minutes and five hours can feel the same. Makes punctuality, planning, and deadlines extraordinarily difficult.

😤

Emotional Dysregulation

Emotions hit harder and faster. Frustration boils over quickly. Joy feels ecstatic. Disappointment feels devastating. The emotional volume is always turned up.

😴

ADHD Fatigue

The exhaustion of maintaining 'normal' functioning. Your brain works overtime to compensate, leaving you depleted by the end of the day. Not laziness - burnout.

⚠️The Masking Tax

Many adults with ADHD have spent years developing coping mechanisms to appear neurotypical. This masking is exhausting and often leads to burnout, anxiety, and depression - conditions that may be treated while the underlying ADHD goes unrecognised.

How ADHD Symptoms Affect Daily Life

Missed deadlines, difficulty prioritising, procrastination on important tasks, brilliant ideas without follow-through, underperformance despite high intelligence. Many adults with ADHD have a trail of unfinished projects and unreached potential.

ADHD Across the Lifespan

How Symptoms Shift with Age

Physical Hyperactivity85%
Internal Restlessness30%
Inattention70%
Emotional Dysregulation55%

Childhood values shown. In adulthood, physical hyperactivity typically decreases while internal restlessness, inattention, and emotional challenges persist or intensify.

Getting Assessed: What to Expect

The Assessment Journey

1
Self-Recognition

You notice patterns that don't match neurotypical expectations. Maybe a social media post resonates, a friend gets diagnosed, or a professional suggests it. This moment of recognition is valid.

2
GP or Primary Care Visit

Your doctor can do an initial screening and refer you to a specialist. Bring examples of how symptoms affect your daily life - specifics matter more than generalities.

3
Specialist Assessment

A psychiatrist or psychologist will conduct a thorough evaluation including childhood history, current symptoms, and ruling out other conditions. This may take one or several sessions.

4
Diagnosis and Plan

If diagnosed, you'll discuss management options: medication, therapy, coaching, lifestyle changes, and tools. Many people find a combination works best.

🌱Preparing for Assessment

Keep a symptom diary for a few weeks before your appointment. Note specific examples of how ADHD symptoms affect your work, relationships, and daily functioning. Concrete examples are far more useful than general statements.

Managing ADHD Symptoms: What Actually Works

💊

Medication

Stimulant and non-stimulant medications can significantly improve focus, impulse control, and emotional regulation. Not a cure, but often transformative when combined with other strategies.

🏃

Exercise

Regular physical activity increases dopamine and norepinephrine - the same neurotransmitters ADHD medication targets. Even a 20-minute walk can improve focus for hours.

📱

External Tools

Apps, timers, visual schedules, and reminders create the external structure that ADHD brains struggle to generate internally. The right tools change everything.

🤝

Coaching and Support

ADHD coaches help develop personalised strategies. Support groups provide understanding and accountability. You don't have to figure this out alone.

You're Not Broken - Your Brain Just Works Differently

ADHD symptoms are real, measurable, and neurological. They're not character flaws, laziness, or a lack of trying. Understanding your symptoms is the first step toward building a life that works with your brain, not against it.

Knowledge Is Power

The moment you understand why you struggle with certain things, you can stop blaming yourself and start building systems that actually work. ADHD is a challenge, but with the right understanding and tools, it's entirely manageable.
