When is tourettes usually diagnosed

Tardive dyskinesia is a potentially irreversible neuroleptic-mediated movement disorder characterized by choreoathetoid movements that may be difficult to distinguish from tics. Haloperidol may be used in the dosage range of 0. When pimozide is used, baseline and follow-up electrocardiograms are recommended. Clonazepam has some use in the treatment of tics and Tourette's syndrome. Side effects include sedation, weight gain, impaired academic performance, social anxiety with school refusal in children and a worsening of attention in children with comorbid ADHD.

The dosage range for clonazepam is 0. Most patients with Tourette's syndrome require medication for up to one to two years. About 15 percent of patients require long-term medication for tic control.

When tics appear to be stable and adequately controlled for a period of four to six months, a slow and gradual reduction in medication, titrated to the point of emergence of functionally impairing tics, should follow.

With such a strategy, occasional drug holidays may be possible in some patients with the waning of tics. With the waxing of tics, incremental increases in medication may follow. Many patients with Tourette's syndrome have comorbid neuropsychiatric conditions, and treatment for these conditions may be necessary.

Treatment of comorbid ADHD has been controversial because of reports that stimulants hasten the onset or increase the severity of tics in some patients. In some cases, it may be necessary to treat both the ADHD and the Tourette's syndrome with a stimulant in combination with either clonidine or guanfacine, or with a neuroleptic agent.

A trial of clonidine or guanfacine alone may be sufficient to adequately treat both conditions. When possible, polypharmacy should be minimized, especially in children. Treatment of obsessive-compulsive disorder with selective serotonin reuptake inhibitors may be effective. With these medications, there is often a significant delay between initiation of treatment and optimal therapeutic response.

This response may take as long as four to six weeks. Behavior therapy is also effective in the treatment of obsessive-compulsive disorder. Figure 3 3 is a simplified scale that can be used to rate problematic behaviors, establish a baseline and determine response to intervention.

This approach is particularly helpful in children with multiple development problems. In children with chronic problems, a scale is especially helpful since it is often difficult to recall how much progress has been made. As a general rule, the parents and teachers should each complete three ratings of the child.

These data, when combined with the physician's assessment in the office, will provide a baseline of severity. The rating scale may then be used to evaluate changes in response to interventions or to monitor severity over time. Coprolalia in younger patients with Gilles de la Tourette syndrome.

The exact cause of Tourette syndrome isn't known, but some research points to changes in the brain and problems with how nerve cells communicate.

An upset in the balance of neurotransmitters chemicals in the brain that carry nerve signals from cell to cell might play a role. Many kids and teens with Tourette syndrome have other behavioral conditions like attention deficit hyperactivity disorder ADHD , obsessive-compulsive disorder OCD , l earning disabilities, or anxiety. To be diagnosed with Tourette syndrome, a child must have several different types of tics — specifically, multiple motor tics and at least one vocal tic — for at least a year.

They may happen every day or from time to time throughout the year. A child with Tourette symptoms may need to see a neurologist, a doctor who specializes in problems with the nervous system. The neurologist may ask the child's parents to keep track of the kinds of tics involved and how often they happen. There isn't a specific diagnostic test for Tourette syndrome — instead, the health care provider diagnoses it after taking a family history, medical history, looking at the symptoms, and doing a physical exam.

Sometimes, imaging tests like magnetic resonance imaging tests MRIs , computerized tomography CT scans, electroencephalograms EEGs , or blood tests can rule out other conditions that might cause symptoms similar to Tourette syndrome.

Just as Tourette syndrome is different for every person, treatment can be different, too. While there isn't a cure for Tourette syndrome, most tics don't get in the way of day-to-day life. If they do, doctors may suggest medicines to help control symptoms. Tourette syndrome is not a psychological condition, but doctors sometimes refer kids and teens to a psychologist or psychiatrist. Seeing a therapist won't stop their tics, but it can help to talk to someone about their problems, cope with stress better, and learn relaxation techniques.

Tics usually are most severe before the mid-teen years. Most people see great improvement in their late teens to early adulthood, though some will have their tics continue into adulthood. Many people don't understand what Tourette syndrome is or what causes it, so they might not know how to act around someone who has tics. If people stare or comment, kids and teens with Tourette syndrome can feel embarrassed and frustrated. Someone who has it might have to explain the condition to others or deal with teasing or gawking.
