Sensory phenomena related to tics, obsessive-compulsive symptoms, and global functioning in Tourette syndrome

Significant correlations were found between sensory phenomena scores and tic severity in 41 Japanese patients with Tourette syndrome.

• Sensory phenomena scores from the University of São Paulo Sensory Phenomena Scale (USP-SPS) and the Premonitory Urge for Tics Scale (PUTS) were positively correlated with overall tic severity measured by the Yale Global Tic Severity Scale (YGTSS).
• Both USP-SPS and PUTS scores showed positive correlations with obsessive-compulsive symptoms (OCS) assessed by the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS).
• The USP-SPS scores were specifically correlated with aggression and sexual/religious dimensions among the six OCS dimensions evaluated.
• PUTS total scores had a significant negative correlation with global functioning, as measured by the Global Assessment of Functioning (GAF) Scale.
