Transient tic disorders are characterized by single or many motor tics. Tics are brief, rapid, repetitive movements often resembling nervous mannerisms.
Tics are typically simple twitches of muscle. There is a huge range in severity. Most mild, transient tic disorders are never brought to the attention of a healthcare provider.
Transient tic disorders are more common in children. Tics are made worse by stress and usually go away during sleep.
