Tourette syndrome or Tourette's syndrome (abbreviated as TS or Tourette's) is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic.
Chronic tic disorder was either single or multiple motor or phonic tics, but not both, which were present for more than a year. Tourette syndrome was diagnosed when both motor and phonic tics were present for more than a year. Tic disorder NOS was diagnosed when tics were present, but did not meet the criteria for any specific tic disorder.

Stereotypic movement disorder is often misdiagnosed as tics or Tourette syndrome (TS). [6] [7] Unlike the tics of TS, which tend to appear around age six or seven, repetitive movements typically start before age three, [1] [8] are more bilateral than tics, and consist of intense patterns of movement for longer runs than tics. Tics are less ...
Motor tics are movement-based tics affecting discrete muscle groups. [4]Phonic tics are involuntary sounds produced by moving air through the nose, mouth, or throat. They may be alternately referred to as verbal tics or vocal tics, but most diagnosticians prefer the term phonic tics to reflect the notion that the vocal cords are not involved in all tics that produce sound.
Knowledge, education and understanding are uppermost in management plans for tic disorders, [6] and psychoeducation is the first step. [14] [15] A child's parents are typically the first to notice their tics; [16] they may feel worried, imagine that they are somehow responsible, or feel burdened by misinformation about Tourette's.
