Tics most often occur in children, but may last into adulthood. Tics occur 3 to 4 times as often in boys as girls. Tics may affect as many as one quarter of all children at some time. Short-lived tics transient tic disorder are common in childhood. A chronic motor tic disorder also exists.
The Management of Tics
Facial tics: MedlinePlus Medical Encyclopedia
Facial tics are uncontrollable spasms in the face, such as rapid eye blinking or nose scrunching. They may also be called mimic spasms. Although facial tics are usually involuntary, they may be suppressed temporarily. A number of different disorders can cause facial tics. They occur most often in children, but they can affect adults as well.
How to Treat Tic Disorders
A tic is a stereotyped repetitive involuntary movement or sound, frequently preceded by premonitory sensations or urges. Most tic disorders are genetic or idiopathic in nature, possibly due to a developmental failure of inhibitory function within frontal-subcortical circuits modulating volitional movements. Currently available oral medications can reduce the severity of tics, but rarely eliminate them. Botulinum toxin injections can be effective if there are a few particularly disabling motor tics.
Back to Tics. Tics don't always need to be treated if they're mild, but treatments are available if they're severe or are interfering with everyday life. Many tics will eventually go away or improve significantly after a few years. If your child is finding school difficult, talk to their teacher about ways of dealing with this. For example, it may help if they're allowed to leave the classroom if their tics are particularly bad.
