The degree of effect TD has on various areas of a person's internal and external life may influence the urgency with which symptoms should be addressed. TD has been associated with increased psychopathology in the underlying psychiatric disorder, as well as decreased quality of life, increased hospitalizations, speech and eating difficulties, cognitive dysfunction, decreased employment, social withdrawal, stigmatization, and amplified emotional distress. Although causality has not been established, for some patients, TD may be a marker of more severe illness.
Assessing the severity, frequency and location of the involuntary movements is insufficient to determine the actual effect of TD because the effect of the movements is multidimensional (eg, distress, dysfunction, social withdrawal, and stigmatization).
Lack of awareness of TD decreases the possibility that patients will voluntarily mention abnormal movements at clinical visits.
