As the name implies, this is diagnosed when the person has only half of the Tourette symptomology, either a motor or a vocal tic. In addition, there can be only one motor tic, rather than multiple as in the case of Tourette's. Motor tics often involve involuntary movements of the head, including grimacing, head banging, and blinking. Neck and shoulder twisting are also common, as are more complex tics like deep knee bending, touching objects, or twirling while walking. The other alternative is vocal tics,
and, as in the case of motor tics, one is enough for a diagnosis if the
other criteria are met. Sniffing, snorting, and throat clearing can be
added as possibilities to the vocal tics mentioned above. Information on
Tourette's and related disorders is available at a fine web
site. Last updated 12/19/03 |
