Tourette’s Syndrome and Comorbid Neurological Condition

Tourette syndrome (TS) often presents with other comorbid conditions in clinical settings. The most common comorbidities are obsessive-compulsive disorder or obsessive-compulsive behaviors, attention deficit hyperactivity disorder, learning disabilities, autism, mood and anxiety disorders, and personality disorders. Comorbid disorders and coexistent psychopathologies are often associated with impaired functioning, more severe course, and poorer long-term outcome. The overall presentation of TS with and without comorbidities can be significantly different and comorbid neuropsychiatric conditions may also change with age. Thus, frequent reassessment of symptoms and re-ordering of treatment priorities are needed when following the child over the developmental timeline.
