Some conditions are less amenable to this treatment, however. For example, people suffering from disorders that make it difficult to tell reality from fantasy might not be good candidates.
The virtual setting presents challenges even for treating ideal patients. Dillon and Bryan admit that treating an avatar can be difficult because you can't read body language or hear someone's tone of voice. But they say that, overall, patients' increased openness improves progress. "In virtual therapy I'm comfortable. I can let things out that I can't normally say in real-life therapy," says Ginnie Murphy, one of Bryan's patients. "I probably would have relapsed if I hadn't had this to keep me stable."
