Medicine:Tardive

Tardive refers to something that is late in appearing. For example, the characteristic symptom of a disease, such as a lesion, may occur a long period after exposure. A tardive symptom could be contrasted with an acute symptom, which appears soon after injury or exposure to disease, although it may also mean a symptom that is gone quickly. On the other hand, chronic conditions are not late-appearing, they are long-lasting.

In the medical field, tardive is most commonly associated with tardive neurological disorders, such as tardive dyskinesia, tardive dystonia, tardive psychosis and tardive akathisia. These disorders arise from the long-term usage of anti-psychotic medication. In addition, there is Eisenmenger's syndrome, also called tardive cyanosis. However, it is unrelated to the other disorders.
