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. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements.
Tourette's syndrome is an inherited neurological disorder. Early onset may be during childhood, and it is characterized by physical and verbal tics. Tourette's often also includes symptoms of both OCD and ADHD indicating a link between the three disorders. The exact cause of Tourette's, other than genetic factors, is unknown.
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.

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.
Athymhormic syndrome is a rare psychopathological and neurological syndrome characterized by extreme passivity, apathy, blunted affect, and a profound generalized loss of self-motivation. The syndrome is believed to be due to damage to areas of the basal ganglia or frontal cortex , specifically the striatum and globus pallidus , responsible for ...
The prevalence of Tourette syndrome among individuals who are autistic is estimated to be 6.5%, higher than the 2% to 3% prevalence for the general population. Several hypotheses for this association have been advanced, including common genetic factors and dopamine , glutamate or serotonin abnormalities.
Coprolalia is an occasional characteristic of tic disorders, in particular Tourette syndrome, although it is not required for a diagnosis of Tourette's and only about 10% of Tourette's patients exhibit coprolalia. [2] It is not unique to tic disorders; it may also present itself as a neurological disorder. [3] [4]
When both motor and vocal tics are present and persist for more than one year, a diagnosis of Tourette syndrome (TS) is likely. TS is an inherited neurobehavioral disorder characterized by both motor and vocal tics. Many individuals with TS may also develop obsessions, compulsions, inattention and hyperactivity. TS usually begins in childhood. [7]
