Awareness & Understanding
When TBI, Trauma, and PTSD Overlap
Similar symptoms, different conditions — and sometimes both.
Brain injuries and trauma responses can share symptoms. That overlap can make things confusing, but it doesn't mean the conditions are the same.

Why they can look alike
An accident or assault can injure the brain and be emotionally traumatic at the same time. Both a TBI and PTSD can affect memory, sleep, mood and concentration.
| Symptom | TBI | PTSD |
|---|---|---|
| Memory difficulties | Possible | Possible |
| Sleep disruption | Possible | Possible |
| Irritability | Possible | Possible |
| Headaches | Common after concussion | Can occur |
| Intrusive trauma memories | Not a defining feature | Characteristic |
| Dizziness | Can occur | Can occur |
Important: symptoms alone cannot establish which condition someone has. TBI and PTSD can also occur together.
Symptoms alone can't tell them apart
Only a qualified professional can assess what is going on. If you've had a head injury and a frightening experience, tell your provider about both — the right care depends on the whole picture.
Recognize
- Symptoms that started after an event that was both physical and frightening
- Being told “it's just stress” or “it's just the injury” without the whole picture being considered
These are things people commonly describe — not a checklist for diagnosis.
Find support
- Share the full story with your doctor — the injury and the emotional experience.
- Ask whether a neurologist, trauma-informed therapist, or both could help.
