Tic - transient tic disorder

• Movements are recurrent and nonrhythmic
• Patients experience an overwhelming inner urge to make the movement
• Movements are most often brief and jerky and include the following:
  • Blinking
  • Raising eyebrows
  • Nostrils flaring
  • Grimacing
  • Opening the mouth
  • Sticking out the tongue
  • Shrugging shoulders
  • Jerking arms
  • Clenching the fists
  • Kicking
  • Curling of the toes

Vocalizations, such as grunts, sniffing, throat clearing, squealing, snorting, clicking, hissing, or moaning may also occur.

Physical causes of transient tic disorder should be considered before a diagnosis is made.

In order to be diagnosed with transient tic disorder, a person must have had tics almost every day for at least 4 weeks, but less than a year.
