Traumatic brain injury
Traumatic brain injury refers to the lasting consequences of an impact to the head, during an accident, a fall or a sudden event. Once the injury is healed, the person may seem completely recovered, while their way of thinking, of memorising or of sustaining effort has sometimes changed deeply.
Depending on the area affected, the effects vary a great deal from one person to another: difficulties with concentration, fatigue that falls without warning, irritability, slowness in finding a word or in moving from one task to another. These effects are not visible at first glance, which often makes them harder to recognise than the injury itself.
A traumatic brain injury often splits a life in two: there is the person before the impact, and the one after, who sometimes relearns how to organise their ideas, recover their words or pace their effort over a day. This turning point stays invisible to those around, but it shapes the whole daily life of the person concerned.
The most exhausting part is not always the difficulty itself, it is having to explain it again and again: to the new colleague surprised by a sudden tiredness, to the teacher who does not understand the slowness, to the relative who believes the episode is closed. Being able to pass on once and for all what really helps avoids having to justify yourself at each new encounter.
Beyond the visible injury
The initial impact heals, but its effects on how the brain works can remain. They mainly affect discreet functions, the ones that go unnoticed as long as they work: holding attention, filtering out noise, retaining an instruction, moving from one activity to another.
- A cognitive fatigue that arrives quickly and takes time to fade.
- Lapses about recent things, while older memories stay intact.
- A heightened sensitivity to noise, light or commotion.
- Emotions that are harder to regulate, especially at the end of the day.
What helps day to day
The aim is not to go back to how things were, but to adjust the environment to preserve the energy available. A few simple pointers change a great deal.
- Moving one task forward at a time, in a calm place, rather than several in parallel.
- Planning real breaks before fatigue spills over.
- Writing down important information so as not to rely solely on immediate memory.
Possible accommodations
The adjustments aim to reduce the mental load and preserve energy, without forcing the person to explain everything again each time.
- At school: a PAP (a school support plan for students with specific needs, in France) or a PPS (an individualised schooling plan, in France) can provide for extra time, written instructions and a quiet seat; support from an AESH (a teaching assistant for students with disabilities, in France) is possible depending on needs.
- At work: RQTH (official recognition of disability status, in France), obtained via the MDPH (the local disability office), grants access to adjustments such as adapted hours, regular breaks or a workstation away from noise.
- In daily life: reminders, lists and a tidy environment limit the effort of memory and the fatigue that follows.

Traumatic brain injury explained to a Child
0–12 years oldWhen the head takes a big hit (from a fall, an accident or a knock during sport), it can cause harm on the inside, even if you can't see anything on the outside.
Afterward, the person may feel very tired quickly, have trouble remembering things, or feel like crying more easily. It's as if their brain needed more time to do things.
Grown-ups and children who've had a knock to the head can also have headaches, dizziness, or find that balance is harder.
The most important thing to know: the person looks normal, but works a little differently. It's invisible, but it's real. They need patience and help while they recover.
Traumatic brain injury explained to a Family caregiver
0–99 years oldA traumatic brain injury is when a knock to the head (accident, fall, sport...) leaves lasting marks. Depending on where the blow landed, it can affect memory, concentration, mood, energy or balance, sometimes for a long time.
What can show up:
- Tiredness that arrives very fast, even after a simple activity
- Forgetfulness or trouble concentrating
- More intense or changeable emotions
- Sometimes headaches, dizziness or balance problems
The important thing to know: these after-effects are often invisible. The person may look "normal" on the surface, but experience real difficulties day to day. It's tiring for them, and also for you who support them. Your efforts to adapt your support really make a difference.
Traumatic brain injury explained to a Preteen
7–12 years oldA traumatic brain injury means the consequences of a big knock to the head (accident, fall, sport). Depending on the area affected, it can change memory, attention, mood or the way of moving for a long time, sometimes forever.
In real life, you might notice:
- forgetfulness, trouble concentrating,
- tiredness that hits fast, even for simple things,
- stronger emotions than before the accident.
You can help in really simple ways:
- by gently repeating what they forget, without sighing,
- by letting them rest when they say they're tired, even if "it looked minor."
From the outside, they may look like before. On the inside, the way things work isn't quite the same anymore.
Traumatic brain injury explained to a Brother or sister
12–99 years oldWhat is a traumatic brain injury? A blow to the head (an accident, a fall, sport...) that leaves lasting traces. Depending on where the brain was affected, it can change all sorts of things: memory, concentration, mood, energy...
What you might notice with your brother/sister:
- He/she falls asleep or gets worn out super fast, even with small everyday things
- Frequent forgetfulness or trouble staying focused for long
- Mood swings that come on faster than usual
- Sometimes headaches, dizziness, or balance problems
The important thing: the after-effects aren't necessarily visible. He/she looks normal, but the brain needs more time for some things. It's not laziness, it's just that things work differently now.
Traumatic brain injury explained to a Close friend
12–99 years oldWhen someone hits their head, in an accident, a fall, or during sport, it can leave lasting traces. Depending on where the blow happened, memory, concentration, balance, or even mood can be affected, sometimes for a long time.
What often surprises people is that the effects aren't always visible: the person seems to be doing fine, but they get tired very fast, forget things more easily, or their emotions are closer to the surface than before.
- Tiredness that hits all at once, even after a very simple activity
- Difficulty concentrating or holding on to information
- A more changeable or more sensitive mood
- Sometimes headaches, dizziness, or a less steady balance
The most important thing is not to confuse "better again" with "fully recovered." They need patience, especially around tiredness and the limits of concentration, and your presence without pressure is already huge for them.
Traumatic brain injury explained to a Teenager
13–17 years oldA traumatic brain injury is when you take a knock to the head (accident, fall, intense sport...) that leaves lasting marks on the way the brain works. And it's important to know: the damage can be invisible, so someone can look normal while they're really struggling on the inside.
The consequences vary depending on the area affected, but you may notice:
- Tiredness that arrives fast and hard, even after something simple, the person wears out
- Forgetfulness or trouble concentrating, which is frustrating when you're trying to keep up in class
- Amplified emotions, feelings rise faster
- Sometimes headaches, dizziness or balance problems
The really important thing: these after-effects can last a long time. That's why, if a friend tells you they had a brain injury, don't act like it's "already healed." It's invisible but very real, and it changes how the person manages their daily life.
Traumatic brain injury explained to a Young adult
18–25 years oldA traumatic brain injury is when a knock to the head (accident, fall, sport) leaves lasting marks. Depending on the area affected, it can impact your memory, your concentration, your energy, your balance or your emotions.
The effects can vary a lot:
- Tiredness that arrives fast and hard, even after something simple
- Forgetfulness or trouble staying focused
- More intense emotions
- Sometimes headaches, dizziness or balance problems
The important thing to know: the after-effects are often invisible. From the outside, the person looks normal, but the way they work on the inside has changed. That's why listening and adapting are essential so everyone can keep taking part in everyday life.
Traumatic brain injury explained to a Parent
18–99 years oldA traumatic brain injury is the lasting effects of a blow to the head, following a fall, an accident or a knock during an activity. Depending on where the brain was affected, it can lastingly change the way your child remembers, concentrates, manages their emotions or gets tired.
Signs to watch for:
- Tiredness that arrives very fast, even after a simple activity
- Difficulty remembering or staying focused
- Stronger emotions or mood changes
- Sometimes headaches, dizziness or loss of balance
The important thing to know: the consequences are often invisible. Your child may look "normal" on the surface, but work differently day to day. They need to be understood, to have accommodations (rest, less stimulation) and regular medical follow-up to support them as best as possible.
Traumatic brain injury explained to a Teacher
18–99 years oldA traumatic brain injury means the lasting after-effects of a knock to the head. Depending on the area affected, you may notice difficulties with memory, attention, behavior or mood, which aren't always visible from the outside.
In the classroom, after a brain injury, you may notice:
- tiredness that arrives very fast, even on simple activities,
- forgetfulness and concentration that falters,
- sometimes headaches, dizziness, slowness,
- raw emotions that don't look like the child from before.
To make the classroom more inclusive:
- adjust the return after an accident: reduced hours, breaks, a lighter workload,
- note progress on what's coming back, rather than the gap with "before."
The return to school is often premature for the family and for the child. Caring vigilance in the following weeks changes everything.
Traumatic brain injury explained to a Coworker
18–99 years oldA traumatic brain injury means the lasting after-effects of a knock to the head. At work, your colleague returning after a brain injury may look "like before" while a lot of things have become complicated on the inside.
You may notice:
- tiredness that hits suddenly at the end of the day, even without an overload,
- forgetfulness, distractions, slowness on tasks that used to be simple,
- a more changeable mood, sometimes irritable,
- great shame at no longer being at the level they were before.
To make working together easier:
- accept a gradual return, with short days or regular breaks, without making it an issue,
- write down reminders to ease working memory.
Recovery after a brain injury is counted in months or years. Calm and kindness are worth as much as a protocol.
Traumatic brain injury explained to a Recruiter or HR
18–99 years oldA traumatic brain injury is a brain injury following a knock to the head (accident, fall, sport). Depending on the area affected, the consequences can last and impact memory, concentration, energy, balance or emotional management.
What may be observed:
- Intense, fast-arriving tiredness, even after light effort
- Difficulty concentrating or forgetfulness
- Greater emotional sensitivity

An important point: the after-effects are often invisible. The person may seem completely functional, while their ability to work or concentrate is really affected. Simple adjustments (regular breaks, a quiet environment, written lists, adjusted deadlines) allow the person to perform according to their real skills.
Traumatic brain injury explained to a Spouse or partner
18–99 years oldA traumatic brain injury is when a blow to the head (an accident, a fall, sport) leaves lasting traces. Depending on what was damaged, it can affect memory, concentration, balance, mood, or energy levels.
Day to day, you may notice:
- Tiredness that hits all at once, even after an ordinary activity
- Memory gaps or trouble staying focused
- More intense emotions, reactions on a hair trigger
- Sometimes headaches, dizziness, or balance problems
The trap: everything looks normal from the outside, but your partner no longer works exactly as before. It's invisible, but it's very real for them.

Traumatic brain injury explained to a Activity leader or youth supervisor
18–99 years oldWhat is a traumatic brain injury? It's an injury to the head (following a blow, a fall, or an accident) that can have lasting effects on everyday functioning. The person often looks normal, but some abilities are affected depending on the area of the brain involved.
What you'll be able to observe:
- Tiredness that comes on fast, even after a short or easy activity
- Difficulty concentrating or more frequent forgetfulness
- More intense emotions: stronger or quicker emotional reactions
- Sometimes headaches, dizziness, or balance problems
How to adapt the activity: offer regular breaks without penalizing participation, accept forgetfulness without reproach, leave emotional room (don't force the game if the person is overwhelmed), reduce sources of noise or intense stimulation if needed. Communicate simply and repeat instructions without frustration.
Traumatic brain injury explained to a Adult
26–59 years oldA traumatic brain injury results from a knock to the head (accident, fall, sport) whose effects can last a long time. Depending on the area affected, it impacts different functions: memory, concentration, balance, managing emotions or energy levels.
The most common consequences:
- Tiredness that arrives quickly, even after an ordinary activity
- Difficulty concentrating or forgetfulness
- More intense emotional reactivity
- Sometimes headaches, dizziness or balance problems
The tricky part: these after-effects often stay invisible. The person seems to work normally at first glance, but their inner organization has changed. That's why those around them, at work or personally, need to adapt their support, even when it isn't obvious at first sight.
Traumatic brain injury explained to a Manager or line manager

- Difficulty concentrating or forgetfulness
- More intense emotions
- Sometimes headaches, dizziness or balance problems
An important point: the after-effects are often invisible. The person seems to work normally, but their energy, their ability to remember or their stamina have changed. Simple adjustments (regular breaks, a quiet environment, a temporarily lighter workload) make staying in the role much easier.
Traumatic brain injury explained to a Senior
60–99 years oldA traumatic brain injury appears after a blow to the head, whether from a fall, an accident or a knock. Depending on the area affected, it can leave lasting marks that impact memory, attention, balance or mood.
What can show up:
- Tiredness that arrives fast and intensely, even after an ordinary activity
- Difficulty remembering or staying focused
- Emotions closer to the surface
- Sometimes migraines, dizziness or balance problems
One of the particularities of a traumatic brain injury is that the after-effects often stay invisible. The person may seem unchanged to others, while they really feel changes in how they work day to day. It's important to recognize this: these difficulties are very real, and independence can be preserved by adapting to one's own pace.
