In schizophrenia, what is the characteristic of the prodromal phase?

In schizophrenia, the prodromal phase is characterized by a decrease in social functioning. This phase represents the period before the onset of the full-blown psychotic symptoms and is often marked by a gradual decline in the individual's ability to engage in social activities and maintain relationships. Individuals may exhibit changes in behavior, such as withdrawing from friends and family, neglecting responsibilities, and displaying an overall decline in their usual social interactions. Although psychotic symptoms may not yet be present, the subtle changes in functioning can be significant indicators of the impending development of schizophrenia.

The other choices do not accurately reflect the nature of the prodromal phase. The presence of psychotic symptoms typically occurs later, during the active phase of the illness. Complete remission of symptoms would not be a characteristic of the prodromal phase, as it is more about the emergence of early signs rather than recovery. Exaggerated affect is generally not typical during this phase, as individuals may experience blunted or flat emotional expression rather than heightened responses.
