(tourette syndrome) A neurologic disorder caused by defective metabolism of the neurotransmitters in the brain. It is characterized by repeated involuntary movements (motor tics) and uncontrollable vocal sounds (vocal tics). The symptoms are usually manifested before the age of eighteen.

(tourette syndrome) A neurological disorder presenting in childhood that is characterized by both motor and phonic tics that occur daily or nearly daily for at least a year and are not attributed to an identifiable cause.

(tourette syndrome) A neuropsychological disorder related to alterations in DOPAMINE metabolism and neurotransmission involving frontal-subcortical neuronal circuits. Both multiple motor and one or more vocal tics need to be present with TICS occurring many times a day, nearly daily, over a period of more than one year. The onset is before age 18 and the disturbance is not due to direct physiological effects of a substance or another medical condition. The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning. (From DSM-IV, 1994; Neurol Clin 1997 May;15(2):357-79)

(tourette syndrome) If you have Tourette syndrome, you make unusual movements or sounds, called tics. You have little or no control over them. Common tics are throat-clearing and blinking. You may repeat words, spin, or, rarely, blurt out swear words. Tourette syndrome is a disorder of the nervous system. It often occurs with other problems, such as: Attention deficit hyperactivity disorder (ADHD); Obsessive-compulsive disorder (OCD); Anxiety; Depression. The cause of Tourette syndrome is unknown. It is more common in boys than girls. The tics usually start in childhood and may be worst in the early teens. Many people eventually outgrow them. No treatment is needed unless the tics interfere with everyday life. Excitement or worry can make tics worse. Calm, focused activities may make them better. Medicines and talk therapy may also help.

(tourette's syndrome) Neuropsychological disorder related to alterations in dopamine metabolism and neurotransmission involving frontal-subcortical neuronal circuits; both multiple motor and one or more vocal tics need to be present with tics occurring many times a day, nearly daily, over a period of more than one year; disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning.

Tourette (too-RET) syndrome is a disorder that involves repetitive movements or unwanted sounds (tics) that can't be easily controlled. For instance, you might repeatedly blink your eyes, shrug your shoulders or blurt out unusual sounds or offensive words.

Tourette syndrome is a complex neurological disorder that is characterized by repetitive, sudden, uncontrolled (involuntary) movements and sounds (vocalizations) called tics. Tourette syndrome is named for Georges Gilles de la Tourette, who first described this disorder in 1885. A variety of genetic and environmental factors likely play...

Tourette syndrome (TS) is a childhood-onset neurodevelopmental disorder characterized by motor and vocal tics and often accompanied by psychiatric problems, such as obsessive-compulsive disorder (OCD) and attention-deficit hyperactivity disorder (ADHD), among others. Tic symptoms typically begin in childhood, peak prior to puberty, and...

Tourette syndrome, rare inherited neurological disorder characterized by recurrent motor and phonic tics (involuntary muscle spasms and vocalizations). It is three times more prevalent in males than in females. Although the cause of Tourette syndrome is unknown, evidence suggests that there may be...
