Summary:The classic form of tic disorder is Tourette syndrome (TS), a childhoodonset, genetic, neurobehavioral disorder characterized by multiple involuntary motor and phonic tics. It is frequently associated with comorbidities, including obsessivecompulsive disorder (OCD) and attentiondeficit (hyperactivity) disorder (ADHD). In addition, TS patients often complain of sleep disturbances and sleeprelated behavioral problems, which have been documented with polysomnographic (PSG) recordings. These include alterations of arousal, decreased percentage (up to 30%) of slowwave sleep (SWS), increased or unaltered duration of SWS, paroxysmal events in stage 4 sleep described as “sudden and intense arousal, apparent disorientation, confusion or combativeness or both, increase in tic activity, and occasional automatismlike activities”, decreased percentage of rapid eye movement (REM) sleep, increased awakenings, and persistence of tics during all stages of sleep.
