Repeated clearing of the throat, sniffing, excessive blinking, and shrugging the shoulders are examples of tics.
Tics are associated with certain diseases, particularly Tourette's disorder. The cause is often unknown. Tics can also be brought on by medicines. Tics may become worse during periods of stress.
