A very important study from the EMTICS project describes early symptoms predicting development of tics in a high-risk population \citep{34170010}.
David Mataix-Cols's lab reports a national registry study of cervical spine injuries in TS \citep{34424277}. Rick of vascular and nonvascular C-spine injuries were 38% to 57% higher, without a significant difference by sex. This epidemiological study confirms previous case reports and suggests that, although most TS patients do not injure their spine, since these injuries can be serious and persistent, doctors should carefully monitor patients with severe disease or nuchal symptoms, and have a low threshold for intervention.
Another Swedish registry study of over 10 million people found a 6.7-fold increased prevalence of insomnia in the 5,877 who had a recorded diagnosis of TS/CTD, after adjusting for demographics and somatic illness \citep{34693569}. Excluding people with ADHD, ASD or a sibling with TS/CTD reduced the odds ratio somewhat, suggesting that part of the risk is attributable to familial factors or these two comorbid diagnoses. Medication for ADHD also increased the likelihood of insomnia. These results suggest that assessment for sleep quality is important in managing TS.
