Post-Traumatic Stress Disorder (PTSD)
Post-traumatic stress disorder (PTSD) appears after an event that exceeded a person's ability to cope: an accident, an assault, a disaster, violence. Long after the real danger has gone, the body and mind keep reacting as if it could come back at any moment.
This reaction is nothing like a lack of willpower or a fragile character. It is a memory that was etched too strongly and that replays without warning, triggered by a detail of the present. The person concerned often knows their situation very well; what they lack is for those around to understand what is happening when a reaction surges up.
The smell of hot brakes, a car door slamming, a figure coming up too fast from behind: sometimes a tiny detail is enough for the body to react before the mind has had time to understand. The heart races, the breath cuts off, the legs tense to flee. For a person living with PTSD, this signal never lies about its intensity, even when the present situation is perfectly safe.
From the outside, the gap is baffling: everything was fine a minute ago. That is precisely what makes daily life exhausting, because you constantly have to explain why an ordinary noise, a date on the calendar, or a crowd can tip everything over. Sharing once what soothes and what triggers, without having to recount the event at every new encounter, already makes daily life much lighter.
What is really at stake
PTSD is not just about nightmares or intrusive memories. It is a whole alert system that stays set to survival mode long after the danger.
- flashbacks (images, sounds, sensations) that impose themselves uninvited
- avoidance of anything that recalls the event, sometimes at the cost of significant withdrawal
- hypervigilance: startle responses, fragile sleep, attention constantly turned toward exits and possible threats
- a feeling of detachment, the impression of being beside oneself or outside the present moment
What soothes in practice
The first need is not to be protected from everything, but to be able to anticipate and keep control.
- give warning before a sudden gesture, contact, or change of plan
- leave a way out, both physical and in the conversation
- respect signs of withdrawal without insisting or dramatising
- know in advance what soothes the person when a reaction builds
Possible accommodations
The accommodations aim above all to reduce the unexpected and preserve a sense of control.
- At school: give warning of evacuation drills and loud noises, allow a seat near the exit, set out these points in a PAP (a personalised support plan, in France) or a PPS (an individualised schooling plan, in France) depending on the situation.
- At work: adjust the hours and the environment (quiet office, back to the wall), allow for recovery time; the RQTH (recognition of disabled worker status, in France) through the MDPH (the local disability rights office, in France) can open up these adjustments.
- In daily life: announce changes in advance, avoid approaching by surprise, and agree on a simple signal to say "I need a break."

Post-Traumatic Stress Disorder (PTSD) explained to a Child
0–12 years oldSometimes, when something very frightening happens to a person, their body stays on alert for a very long time afterward, like a smoke alarm stuck in the "ON" position. The danger is gone, but the body does not know it yet.
Here is what can happen:
- Frightening images come back all of a sudden, without anyone deciding it
- The slightest noise makes them jump, and sleep is hard
- The person avoids the places or people that take them back to the frightening moment
- They feel their emotions more strongly than before
The good news: with time and help, the body's alarm gradually comes back down. Trusted adults can really help someone feel safe again.

- Hypervigilance: startling at the slightest noise, disrupted sleep

- avoidance of the places or people linked to the shock.
You can help in simple ways:
