| 5.3 | Acute headache attributed to whiplash injury [S13.4] | G44.841 |
Diagnostic criteria:
- Headache, no typical characteristics known, fulfilling criteria C and D
- History of whiplash (sudden and significant acceleration/deceleration movement of the neck) associated at the time with neck pain
- Headache develops within 7 days after whiplash injury
- One or other of the following:
- headache resolves within 3 months after whiplash injury
- headache persists but 3 months have not yet passed since whiplash injury
Comments:
The term whiplash commonly refers to a sudden acceleration and/or deceleration of the neck (in the majority of cases due to a road accident). The clinical manifestations include symptoms and signs that relate to the neck, as well as somatic extracervical, neurosensory, behavioural, cognitive and affective disorders whose appearance and modes of expression and evolution can vary widely over time. Headache is very common in this post-whiplash syndrome. The Quebec Task Force on Whiplash-Associated Disorders has proposed a classification in five categories that may be useful in prospective studies.
There are important differences in the incidence of post-whiplash syndrome in different countries, perhaps related to expectations for compensation.
