What are the features of the subtype of schizophrenia associated with catatonia?

The features of the subtype of schizophrenia associated with catatonia include the presence of specific motor symptoms. Catatonia is characterized by a range of physical symptoms that can include motoric immobility (such as stupor or catalepsy), excessive motor activity (that is not initiated by external stimuli), peculiarities of voluntary movement, echolalia (mimicking speech), and echopraxia (mimicking movements). These symptoms can span from extreme agitation to unresponsiveness, reflecting a significant disruption in a person's ability to engage in voluntary movement.

In the context of schizophrenia, catatonia can occur as a prominent feature and involves these distinctive motor behaviors rather than merely an absence of symptoms or increase in social withdrawal. Other choices do not accurately depict the essential characteristics of catatonia as a subtype of schizophrenia. For instance, the presence of a single psychotic symptom would not capture the full spectrum of manic motor behavior that defines catatonia, while a lack of interest in social interactions could align with other types of schizophrenia but doesn’t specifically address the motor symptoms inherent in catatonia. Similarly, the assertion of no psychotic symptoms would contradict the understanding of this subtype, as schizophrenia fundamentally involves psychotic features, and catat
