A convulsive tic associated with a lack of motor coordination, incoherent grunts, and involuntary swearing and coprolalia.
Tourette syndrome (TS) is a neurological disorder that is characterized by motor and vocal tics. The tics are repetitive, rapid, involuntary movements that vary in the age of onset, severity, and complexity but must be present before age 18. The tics often wax and wane over time (American Psychiatric Association [APA], 2000).
Frequent, spontaneous, involuntary body-movement tics (eye blinking, throat clearing, arm thrusting) and vocal tics (grunts, barks), or comments that are socially inappropriate, vulgar, or obscene.
An inherited, neurological disorder characterized by involuntary movements (motor tics) and vocalizations (phonic or vocal tics). Other disorders related to Tourette syndrome (TS) include obsessive-compulsive disorder (OCD), attention deficit/hyperactivity disorder (ADHD), and chronic tic disorder.
A neurological disorder marked by repetitive motor and verbal tics. Affected persons may blink, jerk, grunt, clear their throats, swing their arms, grasp or clasp others, have obsessive-compulsive behaviors, or use verbal expletives uncontrollably. In some instances, people with this condition can control the urge to use these mannerisms while in public, but they may express them vigorously when alone. The condition often appears in multiple family members. It may be caused by a disorder of dopamine uptake in the basal ganglia. Dopamine-blocking drugs such as haloperidol can be used to treat this disorder.
A neurological disorder distinguished by the presence of involuntary and repetitive movements (motor tics) or vocalizations (vocal tics), often referred to as Tourette syndrome.
