Abstract
A case of post-traumatic stress disorder and minor head injury following a road traffic accident is reported. Significant, persisting, and disabling cognitive deficits were reported by the patient and confirmed on neuropsychological testing. A magnetic resonance imaging scan showed no evidence of cerebral damage. A cognitive behavioural treatment approach to the problem is described. The relative contribution of emotional and organic factors to the cognitive and behavioural sequelae of head injury is discussed.
