Transcranial Doppler ultrasound may prove to be another technology that facilitates assessment and further understanding of postconcussion symptoms.
Rimed and Sports-Related Concussions
The recent systematic review by Gardner et al., investigates the use of transcranial Doppler ultrasound in the assessment and monitoring of cerebral blood flow following concussion in sports. Although, only three studies on a small number of athletes were included in the analysis, the results draw attention to the potential role of autonomic changes in the development and maintenance of post-traumatic symptoms.
