Distinguishing primary from functional tics

How often do movement disorder specialists agree when classifying tics? A recent study published in JNNP explores this question with a two-stage approach, seeking a diagnosis from experts first based on video evidence alone and then following the provision of additional clinical data. The study's last author, Dr. Christos Ganos (1), joins host Dr. Saima Chaudhry (2) to discuss the results.
