Akathisia after mild traumatic head injury.

The authors describe the case of a 13-year-old boy who exhibited progressive disabling motor restlessness, torticollis, urinary symptoms, and confusion following a fall from a bicycle. The differential diagnosis of this striking symptom complex in this clinical context can be problematic. In this case, the symptoms ultimately appeared most consistent with severe akathisia resulting from a single administration of haloperidol used at an outside hospital to sedate the patient prior to a head CT scan. The literature on akathisia in pediatric patients, and especially in patients following acute head injury, is reviewed, with suggestions for an approach to these symptoms in this clinical setting.
