This article has been cited by other articles in PMC. This is a practical review of Tourette syndrome, including phenomenology, natural history, and state-of-the-art assessment and treatment.
Computerized literature searches were conducted under the keywords Tourette syndrome,tics, and children-adolescents. Studies have documented the natural history of Tourette syndrome and its frequent co-occurrence with attention problems, obsessive-compulsive disorder OCDand a range of other mood and anxiety disorders, which are often of primary concern to patients and their families.
Proper diagnosis and education are often very helpful for patients, parents, siblings, teachers, and peers. When necessary, available anti-tic treatments have proven efficacious. First-line options include the alpha adrenergic agents and the atypical neuroleptics, as well as behavioral interventions such as habit reversal.
The study of tics and Tourette symdrome has led to the development of several pathophysiological models and helped in the development of management options. However, fully explanatory models are still needed that would allow for accurate prognostication in the course of illness and the development of improved treatments.
Introduction For many, the experience of transient tics may only be a temporary problem of preadolescence, but for those with Tourette syndrome TSthe motor and vocal tics may be part of a crippling constellation of mental health problems that constitute a serious burden of illness.
Tics have been the subject of medical speculation for hundreds of years. Although major gaps remain in our knowledge of the etiology of tics and the most effective treatments, significant advances in our understanding of the neurophysiologic mechanisms at work have been made. Although no ideal treatment for tics has been established, our treatment armamentarium offers many options.
This review summarizes the clinical features, assessment, and treatments of tics. Phenomenology TS is a developmental neuropsychiatric disorder of childhood onset.
There is no diagnostic test for TS. Common tics include eye blinking, grimacing, jaw, neck, shoulder, or limb movements, sniffing, grunting, chirping, or throat clearing.
Tics typically follow a waxing and waning pattern of severity, intensity, and frequency. Other common characteristics of tics include a transient worsening of symptoms during periods of emotional upset; b reduction during periods of concentration that require fine motor skills; and c partial and variable voluntary suppression.
In the natural history of TS, motor tics often begin between the age of 3 and 8, several years before the appearance of vocal tics.
Tic severity usually peaks during the second decade of life with many patients showing a marked reduction in severity by young adulthood. Such urges are experienced as nearly irresistible and occasionally painful, and in some individuals with TS, they are a major source of mental impairment.
Tics often occur in discrete bouts over time scales of days to years, 14 but these patterns have yet to be usefully modeled to predict either outcome or treatment response. The bouts are characterized by brief periods of stable inter-tic intervals of short duration, typically 0.
Understanding the upstream processes that govern the timing of tic expression ultimately may clarify both neural events occurring in millisecond time scales as well as the natural history of tic disorders that occurs over the first two decades of life. The description of tics as simply intermittent trains of completely involuntary motor discharge is incomplete.
Interestingly, activities that require focused attention and fine motor control, such as reading aloud, playing a musical instrument, engaging in certain sports, and even performing surgery, are associated with transient improvements in tics.
Finally, although much diminished, tics can sometimes occur during sleep, distinguishing them from many other movement disorders. Indeed, polysomnographic studies indicate that sleep disturbance is also part of the TS picture, with decreased quality and increased arousal phenomena.
It is generally agreed that about 50 percent of patients with TS have substantial obsessive-compulsive OC symptoms. OC behaviors are also commonplace in children with TS. Attention-deficit hyperactivity disorder ADHD is frequently diagnosed in children with TS, with a prevalence as high as 70 percent.Glottal Gregg drowns, an analysis of the tourettes syndrome disorder in motor skills his cleanliness is very passionate.

Persistent (chronic) motor tic disorder is characterized by the presence of single . Tourette's Syndrome is a motor disorder characterized by the presence of motor or vocal tics. The diagnosis is confirmed by the presence of these tics and is marked by an impairment to social and/or occupational functioning.
Tourette syndrome (TS or simply Tourette's) is a common neuropsychiatric disorder with onset in childhood, characterized by multiple motor tics and at least one vocal (phonic) tic. These tics characteristically wax and wane, can be suppressed temporarily, and are typically preceded by an unwanted urge or sensation in the affected muscles.
