Abstract

Aim of this study was to evaluate the relationships between tics, sleep disorders and behavioral disturbances. Fourty-nine consecutive children and adolescents with tics have been studied by the following procedure: a) the Yale Global Tic Severity Scale (YGTSS) was administered in order to establish the severity of tics; b) the Child Behavior Checklist (CBCL) was used to evaluate behavioural disturbances; c) the Sleep Disturbance Scale for Children (SDSC) was filled out in order to assess the presence of sleep disorders.

Sleep-wake transition disorders (SWTD) were the most frequent sleep disturbances found in our sample, followed by disorders of initiating and maintaining sleep (DIMS). These latter sleep disturbances were highly correlated with the severity of tics. Internalization pr...Continue Reading
