Quelle est la différence entre TDA et TDAH ?

What is the difference between ADD and ADHD?

People often confuse ADD and ADHD, two attention disorders that are similar but not identical.
The difference lies mainly in the presence — or absence — of hyperactivity.
Understanding this nuance helps to better identify the needs of each person and to adapt support, whether at school, at work or at home.


ADD: an attention disorder without hyperactivity

ADD (attention deficit disorder) is characterised by difficulties maintaining concentration on a task, organising ideas or managing time.
A person with ADD is not hyperactive, but rather distractible, dreamy or slow in certain situations.

They may:

  • forget instructions,
  • lose their belongings,
  • struggle to finish what they start,
  • be overwhelmed by their thoughts.

In children, ADD often shows up as an apparent “nonchalance”.
In reality, the brain struggles to filter information: everything attracts attention, which makes concentration hard to sustain.


ADHD: ADD with hyperactivity and impulsivity

ADHD (attention deficit hyperactivity disorder) includes the symptoms of ADD, but adds a motor and emotional dimension.
A person with ADHD has difficulty staying still, talks a lot, frequently interrupts or acts without thinking.

Three main profiles exist:

  1. Inattentive: close to ADD, without notable restlessness.
  2. Hyperactive-impulsive: fidgets, speaks quickly, acts before thinking.
  3. Combined: combines both dimensions.

This hyperactivity is not a lack of willpower, but neurological hyperstimulation: the brain constantly seeks to capture new sources of interest.


Why the distinction matters

Understanding whether a person has ADD or ADHD makes a big difference to support.
ADD mainly requires tools to structure thinking, manage time and organise priorities.
ADHD, on the other hand, also requires work on regulating energy and impulsivity.

A full assessment carried out by a professional (paediatric neurologist, psychologist, or psychiatrist) makes it possible to evaluate the symptoms and adapt follow-up.
Some adults discover their ADD or ADHD late, after years of fatigue or misunderstanding.


How to live better with ADD or ADHD

Whatever the form of the disorder, the most important thing is to learn to channel attention rather than force it.
Digital tools such as Dys’tap.io can help structure tasks and maintain motivation through playful activities.

On AidToi.fr, practical advice helps you get organised day to day:

  • using a visual agenda,
  • breaking tasks down into small steps,
  • creating a calm environment,
  • valuing break times to recharge attention.

ADHD can also become a creative strength, as it often comes with great curiosity, quick thinking and a strong capacity for adaptation.


In summary

👉 ADD refers to an attention disorder without hyperactivity.
👉 ADHD adds a motor and impulsive dimension.
Both require understanding, support and suitable tools.
With a caring approach, each person can learn to use their way of functioning as a resource rather than a constraint.
