Eight months of one consistent, isolated feature

Grace, 58, has for the past eight months had persistent auditory hallucinations (hearing her late husband's voice offering reassurance) without ever developing delusions, thought disorder, negative symptoms, or a mood episode. A full medical work-up and substance history are unremarkable, and the pattern has remained essentially unchanged and clearly described across eight months of follow-up.
