Trouble obsessionnel compulsif (TOC)
اضطراب الوسواس القهري
A mental health condition involving unwanted, intrusive thoughts (obsessions) that drive repetitive behaviors or mental acts (compulsions) performed to reduce distress. It's distinct from everyday preferences for order or cleanliness — the thoughts and behaviors are distressing, time-consuming, and interfere with daily life. Effective treatments include a specific type of cognitive behavioral therapy and, often alongside it, medication.

Réponse rapide
Obsessive-compulsive disorder (OCD) is a condition in which a person has unwanted, distressing thoughts, images or urges (obsessions) and feels driven to perform repetitive behaviours or mental acts (compulsions) to reduce the distress.
Common themes include fear of contamination, doubts and checking, a need for symmetry or order, and unwanted intrusive thoughts. The rituals take up time and interfere with life, and the person often knows they are excessive.
OCD is treatable. Exposure and response prevention (a form of cognitive behavioural therapy) and medicines, chosen with a mental-health professional, help most people. Seek help if thoughts or rituals take over your day.
Symptômes
Obsessions
Unwanted, intrusive thoughts, images or urges that cause distress — for example fear of germs or of harming someone.
Compulsions
Repetitive behaviours or mental acts — such as washing, checking, counting or repeating — done to ease distress.
Fear of contamination and excessive cleaning or handwashing
Repeated checking
For example locks, appliances or safety.
A need for order, symmetry or exactness
Intrusive taboo, aggressive or unwanted thoughts
These are a symptom and do not mean a person will act on them.
Spending more than an hour a day on rituals
Avoidance of triggers

Comment le diagnostic est-il posé ?
A doctor or mental-health professional diagnoses OCD from a detailed conversation about obsessions, compulsions and their impact.
Clinical interview
Nature of thoughts and rituals, time spent and the effect on life.
Structured assessment
Tools such as the Y-BOCS measure severity.
Assessing other conditions
Depression, anxiety, tic disorders and other issues often coexist.
Physical check
To exclude medical or medicine-related contributions, when relevant.
Traitement
Treatment depends on severity and personal circumstances, and is decided with a mental-health professional.
Exposure and response prevention (ERP)
A form of CBT in which you gradually face triggers without performing the ritual; it is the leading psychological treatment.
Medicines
Certain antidepressants, usually at higher doses and for longer than for depression, under specialist supervision.
Combined treatment
Therapy and medicines together for moderate to severe OCD.
Support and education
Family involvement and support groups help.
Specialist treatments
For severe, treatment-resistant OCD.
Reassurance-seeking and rituals give short-term relief but keep OCD going; therapy addresses this cycle.
