prodromal's Usage Examples:

"Researchers have investigated the possibility of treating schizophrenia during the prodromal stage or even before symptoms start (such as when the likelihood of hereditary transmission is high).

Before the disease becomes full-blown, schizophrenics may go through a period called the prodromal stage, lasting about a year, when they experience behavioral changes that precede and are less dramatic than those of the acute stage.

The prodromal stage is followed by the acute phase of the disease, which usually requires medical intervention.
