Neurocognitive Functioning in Tourette Syndrome

Individuals living with Tourette syndrome (TS) may benefit from cognitive assessment, as it may elucidate specific difficulties for which someone could receive accommodation and highlight relative strengths to build upon. Eventually, cognitive assessment could help predicting symptom trajectory or treatment outcome. However, the literature on cognition in TS is often equivocal, which may be at least partly attributed to small samples, inconsistent consideration of co-occurring conditions, psychotropic medication, and developmental influence. Here, we aimed to provide a comprehensive overview of the literature on cognition in TS, to disentangle conflicting findings and make suggestions of how the findings can be applied to promote better outcomes.
