| IHS | Diagnosis | ICD-10 |

| 5.1.2 | Acute post-traumatic headache attributed to mild head injury [S09.9] | G44.880 |
Diagnostic criteria:
- Headache, no typical characteristics known, fulfilling criteria C and D
- Head trauma with all the following:
- either no loss of consciousness, or loss of consciousness of <30 minutes' duration
- Glasgow Coma Scale (GCS) ≥13
- symptoms and/or signs diagnostic of concussion
- Headache develops within 7 days after head trauma
- One or other of the following:
- headache resolves within 3 months after head trauma
- headache persists but 3 months have not yet passed since head trauma
Comment:
Mild head injury may give rise to a symptom complex of cognitive, behavioural and consciousness abnormalities and a GCS of ≥13. It can occur with or without abnormalities in the neurological examination, neuroimaging (CT scan, MRI), EEG, evoked potentials, CSF examination, vestibular function tests and neuropsychological testing. There is no evidence that an abnormality in any of these changes the prognosis or contributes to treatment. These studies should not be considered routine for patients with ongoing post-traumatic headache. They may be considered on a case-by-case basis, or for research purposes.
