tic [tik] (Fr.) an involuntary, compulsive, rapid, repetitive, stereotyped movement or vocalization, experienced as irresistible although it can be suppressed for some length of time;
occurrence is increased by stress and reduced during sleep or engrossing activities. Tics may be of psychogenic or neurogenic origin and are subclassified as either simple,
such as eye blinking, shoulder shrugging, coughing, grunting, snorting, or barking (LOL!); or complex, such as facial gestures, grooming motions, coprolalia (obscene language),
echolalia (repeating the most recently heard word or sound), or echokinesis (imitation of another's movements).
She's had a stroke not a little bump on the head. Her coprolalia has been going on for years!!
Sounds like an excellent long distance neuro exam of the damaged one.
