Study Notes

Tics and Tourette Syndrome

  • Transient tics occur in 5-20% of children, while Tourette syndrome (TS) affects about 1% of children, characterized by persistent motor and vocal tics.
  • 65% of individuals with TS will have no tics or only mild tics by adulthood.
  • Tics are more common in boys than girls, with a ratio of 2-3:1.

Detection and Treatment of Comorbidity

  • Co-morbid conditions such as OCD, ADHD, depression, anxiety, and behavioral problems are more prevalent in individuals with TS.
  • These comorbid conditions often cause the major impairment and should be treated first before assessing the level of disability caused by tics.

Education and Behavioral Treatments

  • Education is crucial for individuals with tics, their families, and those they interact with, especially in schools.
  • Behavioral interventions, such as Habit Reversal, Comprehensive Behavioral Interventions, and Exposure and Response Prevention, are effective in reducing tics.
  • These treatments have similar effect sizes to antipsychotic medication.

Pharmacological Treatments

  • Adrenergic α2 agonists, such as Clonidine, have been shown to reduce tic severity and frequency in open studies.
  • Clonidine has a therapeutic dose of 3-5µg/kg, and the dose should be built up gradually to avoid side effects.
  • Guanfacine has also been shown to be effective in treating tics and may be beneficial for individuals with comorbid ADHD.
  • Antipsychotics, such as Pimozide, Haloperidol, and Risperidone, may be effective in alleviating tics, but adverse effects may outweigh beneficial effects.
  • Aripiprazole is a well-tolerated and effective treatment for children with TS, with a significant decrease in serum prolactin concentration and increased body weight.

Treating Tourette's Syndrome

  • First line treatment for Tourette's Syndrome is educational and behavioral treatment
  • If educational and behavioral treatment is not fully effective, proceed to second line treatment

Second Line Treatment

  • Second line treatment involves administering clonidine or guanfacine
  • If clonidine or guanfacine is not fully effective or poorly tolerated, proceed to third line treatment

Third Line Treatment

  • Third line treatment involves antipsychotic treatment with aripiprazole or risperidone
  • If antipsychotic treatment is not effective, proceed to fourth line treatment

Fourth Line Treatment

  • Fourth line treatment involves considering older or experimental treatments
  • It is extremely rare to reach the fourth line treatment in practice, as most cases can be effectively treated with prior options
