Attention-Deficit/Hyperactivity Disorder (ADHD)

warning

Some traits associated with ADHD may sometimes be observed in everyone.

What matters is their intensity, frequency, duration, persistence over time, and impact on daily life.

An isolated instance of behavior or behavior observed only occasionally is therefore never sufficient to conclude that ADHD is present.

Only a trained professional can carry out a full diagnostic assessment.

Similarly, certain situations—such as a period of significant stress, fatigue, anxiety, burnout, social exhaustion, or sensory overload, can temporarily exacerbate behaviors or difficulties that resemble certain characteristics of autism, without necessarily indicating ADHD.

important

ADHD is a neurodevelopmental difference, not a lack of will.

People with ADHD have different neurological functioning that affects attention, executive functions, energy management, impulsivity, and emotional regulation.

Definition

The Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that mainly affects the brain’s executive functions.

It typically manifests through difficulties in:

  • regulating attention;
  • organizing and planning;
  • managing time;
  • controlling impulsivity;
  • regulating activity levels;
  • managing certain emotions.

ADHD begins in childhood and often persists into adulthood.

There are three main presentations:

  • predominantly inattentive;
  • predominantly hyperactive-impulsive;
  • combined.

Every person with ADHD has a unique profile, with symptoms, needs, and strengths that are specific to them.

Main characteristics

Attention and concentration

People with ADHD may have difficulty maintaining attention on tasks that are not stimulating or are repetitive.

This can show up as:

  • significant distractibility;
  • frequent forgetfulness;
  • difficulty following long tasks;
  • attention strongly dependent on interest.

note

Conversely, they may also experience periods of hyperfocus, characterized by intense concentration on a particularly stimulating activity.

Executive functions

ADHD can affect organization, prioritization, planning, time estimation, task initiation, and tracking ongoing actions.

ADHD can affect:

  • organization;
  • prioritization;
  • planning;
  • time estimation;
  • getting started on tasks;
  • following through on ongoing tasks.

important

These difficulties do not reflect a lack of competence or motivation.

Impulsivity

Some people with ADHD may:

  • answer before a question is finished;
  • interrupt a conversation involuntarily;
  • make quick decisions;
  • act before fully analyzing a situation.

important

Impulsivity varies greatly from person to person.

Hyperactivity

important

Hyperactivity is not always present.

When present, it may manifest as:

  • need for movement;
  • difficulty remaining still for long;
  • physical agitation;
  • permanent mental agitation;
  • continuous flow of ideas.

note

In adults, hyperactivity often manifests itself more mentally than physically.

Emotional regulation

Emotional regulation may be more complex.

Some people with ADHD may show:

  • more intense emotional reactions;
  • greater frustration;
  • strong sensitivity to criticism;
  • difficulty stepping back in certain situations.

important

These reactions are generally linked to neurobiological mechanisms and not to a lack of emotional maturity.

ADHD: examples and adaptations

Characteristic Example ❌ Don’t ✅ Do Optimal adaptation
Maintaining attention 2-hour meeting without interaction Interpret distraction as lack of interest Check engagement through regular interaction Shorter meetings with breaks
Distractibility Working in an open space Require constant concentration despite interruptions Reduce unnecessary demands Noise-cancelling headphones, protected time
Organizational difficulty Project with several deadlines “Get organized better” Help structure priorities Checklists, visual tools
Time management Underestimating time needed Consider it lack of seriousness Help break tasks down Clear intermediate milestones
Procrastination Uninspiring administrative task Equating this with laziness Understanding the difficulty of getting started Breaking the task into smaller parts
Impulsivity Cutting someone off during a meeting See it as deliberate impoliteness Reframe without judgment Structured speaking turns
Motor hyperactivity Need to get up regularly Require the person to remain seated Allow for discreet movement Sit-stand desk, active breaks
Mental hyperactivity Multiple simultaneous ideas Ask the person to slow down without a structure Channel their thoughts Whiteboard or idea-capture tool
Emotional sensitivity Providing critical feedback on work Being very blunt Offering factual and balanced feedback Structured feedback
Hyperfocus Intense concentration on a task Interrupt continuously Respect periods of concentration Work windows without interruption

Frequently observed strengths

note

Every person with ADHD is different. However, certain strengths are frequently observed.

Strength Concrete example
Creativity Finding original solutions to complex problems
Divergent thinking Quickly generating many alternative ideas
Reactivity Acting effectively in emergency situations
Adaptability Adjusting rapidly to changes in context
Curiosity Exploring new tools or methods spontaneously
Energy and enthusiasm Mobilizing a team around a motivating project
Hyperfocus Producing very high-quality work on a topic of passion
Entrepreneurial spirit Identifying opportunities for improvement quickly
Initiative Acting quickly when action seems necessary
Resilience Continuing despite difficulties or failures
Big-picture perspective Quickly connecting diverse pieces of information
Ability to improvise Finding solutions using available resources

Common misconceptions

important

Our perception of ADHD is often influenced by the media, social media, or certain oversimplified portrayals.

“People with ADHD lack willpower”

❌ False. ADHD is not a problem of motivation or willpower. The difficulties stem primarily from differences in how the mechanisms that regulate attention and executive functions work.


“People with ADHD are lazy”

❌ False. People with ADHD often put in a lot of effort to complete tasks that others find easier. The difficulty mainly lies in getting started and organizing their actions.


“If someone can play a video game for 6 hours, they can’t have ADHD”

❌ False. ADHD is not an attention deficit, but a difficulty regulating one’s attention. A person with ADHD may have trouble focusing on a task that isn’t very stimulating, while still being able to enter a state of hyperfocus on an exciting activity (in search of dopamine).


“ADHD affects only children”

❌ False. ADHD begins in childhood but often persists into adulthood. Its symptoms often change over time.


“All people with ADHD are hyperactive”

❌ False. Some people primarily experience attention difficulties without any visible hyperactivity. Hyperactivity is only one possible component of the disorder.


“A person with ADHD is necessarily disorganized”

❌ False. Many people with ADHD develop highly sophisticated organizational systems to compensate for their executive function difficulties.


“When a person with ADHD forgets something, it’s because they’re not interested in it.”

❌ False. Forgetfulness is often linked to difficulties with working memory and attention management, not to a lack of interest or engagement. A person with ADHD may forget a task that they actually consider important.


“People with ADHD never finish what they start”

❌ False. When a topic is stimulating or meaningful, people with ADHD can demonstrate tremendous perseverance and remarkable commitment.


“ADHD is immediately obvious”

❌ False. Many people with ADHD develop coping strategies that make their difficulties less visible to others. However, this adaptation can require a lot of energy and lead to significant cognitive fatigue.


“There is a medication that cures ADHD.”

❌ False. Medications can help reduce certain symptoms, but they do not cure ADHD. They are one tool among many for better managing daily life.

Key points

important

  • ADHD is a neurodevelopmental disorder that begins in childhood and often lasts throughout life.
  • It mainly affects attention, executive functions, impulsivity, and sometimes hyperactivity.
  • Difficulties are not due to lack of will or effort.
  • Difficult situations often arise from poorly adapted environments.
  • Simple accommodations can significantly improve everyday functioning.
  • People with ADHD can bring valuable strengths such as creativity, innovation, adaptability, energy, hyperfocus, and quick problem-solving.
