‘B’ was categorized in the Class V because he showed functional
deficits related to both content and intrusiveness of hallucinations.
Deficits related to content were in the form of poor self-esteem,
such as frequent self-depreciating remarks, poor posture, lack of
social interaction, and poor motivation. Observation and self-report
confirmed that the intrusive nature of hallucinations did interfere
with his functional performance. The patient showed inappropriate
behavior while apparently responding to internal stimuli, such as
gesticulating and muttering to self, not related to the outside
environment; inappropriate affect & poor attention to tasks.
