Transient tic disorder, which commonly affects children, possibly results from a combination of factors, such as hereditary factors, brain abnormalities and neurotransmitters, which are chemicals responsible for delivering nerve signals to the cells, according to Healthline. To treat tics, doctors may prescribe medications that change neurotransmitter levels.
Tics are unusual, involuntary movements or sounds that occur suddenly, explains Healthline. People with tics typically blink repeatedly, clench their fists, shrug their shoulders or raise their eyebrows uncontrollably without a rhythm. Tics may also involve incessantly grunting, moaning, clicking the tongue or clearing the throat.
Many children experience tics that resolve without treatment in less than a year, notes Healthline. People who experience simultaneous physical and vocal tics suffer from a tic disorder called Tourette syndrome. Studies reveal that rare cases of Tourette syndrome result from a genetic mutation.
Doctors typically recommend therapy and medication to treat tics that affect an individual's performance in school or at work. In cognitive behavioral therapy sessions, patients learn to control their thoughts, emotions and actions. Stress management is also crucial, because stress can aggravate tics. People around a child with tics should not mention his tics to avoid making him self-conscious about his uncontrollable symptoms, advises Healthline.
