Tic disorders
Syndromes in which the predominant manifestation is some form of tic. A tic is
an involuntary, rapid, recurrent, nonrhythmic motor movement (usually involving
circumscribed muscle groups) or vocal production that is of sudden onset and that
serves no apparent purpose. Tics tend to be experienced as irresistible but usually
they can be suppressed for varying periods of time, are exacerbated by stress, and
disappear during sleep. Common simple motor tics include only eye-blinking,
neck-jerking, shoulder- shrugging, and facial grimacing. Common simple vocal
tics include throat-clearing, barking, sniffing, and hissing. Common complex tics
include hitting oneself, jumping, and hopping. Common complex vocal tics
include the repetition of particular words, and sometimes the use of socially
unacceptable (often obscene) words (coprolalia), and the repetition of one's own
sounds or words (palilalia).
F95.0 Transient tic disorder
Meets the general criteria for a tic disorder but the tics do not persist longer than
12 months. The tics usually take the form of eye-blinking, facial grimacing, or
head-jerking.
F95.1 Chronic motor or vocal tic disorder
Meets the general criteria for a tic disorder, in which there are motor or vocal tics
(but not both), that may be either single or multiple (but usually multiple), and
last for more than a year.
F95.2 Combined vocal and multiple motor tic disorder [de la Tourette]
A form of tic disorder in which there are, or have been, multiple motor tics and
one or more vocal tics, although these need not have occurred concurrently. The
disorder usually worsens during adolescence and tends to persist into adult life.
The vocal tics are often multiple with explosive repetitive vocalizations, throatclearing,
and grunting, and there may be the use of obscene words or phrases.
Sometimes there is associated gestural echopraxia which may also be of an
obscene nature (copropraxia).
