Passage 18 - What is Tic?
A tic
is a repeated, impulsive action, reflexive in nature, which the actor feels powerless
to control or avoid. Only when the individual performs the tic, is tension and anxiety
released within the individual with a tic disorder. Tics can be triggered by an emotional
state or
sensation, or can happen for no obvious reason. General types of tics include
verbal tics, facial tics, and other muscular tics. Physical and psychological therapy and
medication can cause tics to go away, often permanently. Muscular
tics look something
like twitches or quick grimaces, and often affect the eyes and hands. Muscular tics can
affect multiple muscles at once. Some forms of stuttering are
caused by muscular tics in
the throat, tongue, or vocal cords when speaking or preparing to speak.
