What generally characterizes catatonic behavior?

Catatonic behavior is primarily characterized by unresponsiveness and immobility. Individuals exhibiting catatonia may remain in a fixed position for extended periods, displaying a lack of movement or response to external stimuli. This state can include features such as stupor, in which the person appears to be in a daze or unresponsive, and state of rigidity, where the body becomes tense and stiff. Additionally, there might be periods of peculiar movements or postures, but the overarching characteristic remains the person's apparent lack of engagement with their surroundings.

In contrast to excessive movement or high energy levels, catatonic behavior is marked by a distinct absence of these traits. Similarly, frequent verbal communication is not a hallmark of catatonia; instead, individuals often exhibit a lack of speech or noticeable reduction in verbal interaction. Therefore, the defining trait of unresponsiveness and immobility accurately captures the essence of catatonic behavior.
