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.
Observed prevalence rates are higher among children than adults because tics tend to remit or subside with maturity and a diagnosis may no longer be warranted for many adults. [38] Up to 1% of the overall population experiences tic disorders, including chronic tics and transient (provisional or unspecified) tics in childhood. [54]
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.

Causes and origins of Tourette syndrome have not been fully elucidated.Tourette syndrome (abbreviated as Tourette's or TS) is an inherited neurodevelopmental disorder that begins in childhood or adolescence, characterized by the presence of multiple motor tics and at least one phonic tic, which characteristically wax and wane.
The fifth revision of the DSM was published in 2013: it defined tic disorders in the motor disorders chapter of the neurodevelopmental disorders, and removed the word stereotyped from the description of tics; replaced transient tic disorder with provisional tic disorder; differentiated motor and vocal chronic tic disorder; removed the use of ...
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. [14]
Typically, symptoms of coprolalia follow the development of phonic or motor tics by four to seven years. The severity of symptoms tends to peak during adolescence and subside during adulthood. [9] In Tourette syndrome, compulsive swearing can be uncontrollable and undesired by the person uttering the phrases.
