Summary
Tics are brief, sudden, non-rhythmic, repetitive movements. Tics can be motor or vocal. Further, both motor and vocal tics can be either simple or complex. Simple tics typically involve only one group of muscles and are brief and meaningless, whereas complex tics may last longer and appear more purposeful. Tic disorders usually begin in childhood and are classified according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) into four groups: (1) provisional tic disorder, (2) chronic motor or vocal tic disorder, (3) Tourette disorder (or Gilles de la Tourette syndrome), (4) tic disorder not otherwise specified. As tics can resemble almost any other movement disorder, phenotypic analysis alone is insufficient and patients must be questioned whether the execution is preceded by a premonitory sensation (urge to do, urge to move) and whether a temporary control of the movement can be achieved. Also, relief following execution of the tic is frequently reported. There are no biomarkers available for tics and diagnosis therefore remains strictly clinical.
