Réponse rapide
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition marked by persistent patterns of inattention, hyperactivity and/or impulsivity that interfere with functioning. It usually starts in childhood and often continues into adulthood.
Signs include difficulty sustaining attention, being easily distracted, forgetfulness, fidgeting or restlessness, talking excessively, and acting without thinking. Presentation differs between children, adolescents and adults.
ADHD is diagnosed through a comprehensive clinical assessment, not a single test. Management combines behavioural strategies, education and support, and — for many people — medicines prescribed and monitored by a specialist.

Comment le diagnostic est-il posé ?
ADHD is diagnosed by a specialist — such as a paediatrician, psychiatrist or psychologist — after a full assessment.
Detailed history
Symptoms in more than one setting (home, school, work), starting in childhood, and their impact.
Information from others
Reports from parents, teachers or partners, and behaviour rating scales.
Excluding other causes
Hearing or vision problems, sleep problems, anxiety, depression, learning difficulties or medical conditions.
Physical assessment
As needed, including growth, heart health and blood pressure before medicines.
Traitement
ADHD treatment is individualised and can include several approaches. Medicines, when used, are prescribed and monitored by a specialist.
Education and support
Understanding ADHD helps families, teachers and workplaces support the person.
Behavioural strategies and parent training
Consistent routines, clear expectations and rewards, especially in children.
Medicines
Stimulant and non-stimulant medicines can reduce symptoms; choice, dose and monitoring are decided by the specialist.
Psychological therapies
CBT and coaching can help adults and older adolescents with organisation and emotional regulation.
Accommodations
Adjustments at school or work — extra time, structured tasks, a quiet environment.
Medicines need regular review. Don't stop them abruptly or adjust doses without medical advice.
