Editing Tic (section)

===Simple or complex===
'''Simple motor tics''' are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging.<ref name=SingerBehavior>{{cite journal | author = Singer HS | date = Mar 2005 | title = Tourette's syndrome: from behaviour to biology | journal = Lancet Neurol | volume = 4 | issue = 3| pages = 149–59 | doi = 10.1016/S1474-4422(05)01012-4 | pmid = 15721825 | s2cid = 20181150 }}</ref> Motor tics can be of an endless variety and may include such movements as hand clapping, neck stretching, mouth movements, head, arm or leg jerks, and facial grimacing.

A '''simple phonic tic''' can be almost any sound or noise, with common phonic tics being throat clearing, sniffing, or grunting.<ref name=SingerBehavior/>

'''Complex motor tics''' are typically more purposeful-appearing and of a longer nature. They may involve a cluster of movements and appear coordinated.<ref name=SingerBehavior/> Examples of complex motor tics are pulling at clothes, touching people, touching objects, [[echopraxia]] (repeating or imitating another person's actions) and [[copropraxia]] (involuntarily performing obscene or forbidden gestures).

'''Complex phonic tics''' include [[echolalia]] (repeating words just spoken by someone else), [[palilalia]] (repeating one's own previously spoken words), lexilalia (repeating words after reading them), and [[coprolalia]] (the spontaneous utterance of socially objectionable or taboo words or phrases). Coprolalia is a highly publicized symptom of [[Tourette syndrome]]; however, only about 10% of TS patients exhibit coprolalia.<ref name=SingerBehavior/>

Martino, et al. have argued that tics may be considered physiological, or developmentally typical.<ref>Martino D, Espay AJ, Fasano A, Morgante F. Unvoluntary motor behaviors.
