Montreal schizophrenia patients face their demons through virtual reality

A pilot project at Montreal'sPhilippe-PinelInstitute has patients withschizophrenia confrontingvoices that torment them by way of a virtual reality experience.

The project, developed by psychiatrist and researcher Alexandre Dumais, allows patients to create computer-generated avatars that look and talk like the demons they face inside their heads.

Richard Breton, a 52-year-old father of two, has struggled withschizophrenia since his early 20s. He told CBC's French-language service that his episodes of psychosis and paranoia at times put his life at risk.

Tormented by voices and hallucinations despite medication and traditional therapy, Breton turned to Pinel'spilot project.

He was the first participant in the project, inspired by aU.K. study conducted in 2010.

Bretondescribed the appearance of his internal tormentor to a design technician, and with the help of a virtual reality headset, came face to face with that tormentorprojected before his eyes.

"The patient can'tavoid it," said Dumas. "It allows patients to manage their emotions while they're being persecutedand learn to confront [the avatar]."

Dumas stays closely connected to the patient during the interaction, reading off a list of phrases submitted by the patient the kinds of things the personhears the tormentor say.

"You're not a good father. Nobody loves you," the avatar tells Breton, in a satanic voice.

Learning to fight back

In the beginning,patients find the interaction very difficult. But over six sessions, the psychiatrist helps them to respond to the insults they're hearing andto develop defence mechanisms.

"I'm a good person," Breton has learned to respond. "Give me any trouble, and I'll make you go back inside."

For Breton, wrestling with a projection of his inner demon has worked.

"I'm able to fight it," said Breton. "The voices havediminished from 80 to 90 per cent."

He credits the project with helping him return to work and engage in more social activities.

"The voices were too invasive," he said of his life before this experiment. "I isolated myself because every time I went out, the devil caught up with me."

Encouraging results

Nineteen patients at Pinel have taken part in the pilot project since it was launched in September 2015. Fifteenhave reported seeing a significant improvement.

"The numbers speak for themselves," said Dumas. "It worked in Britain, it works here."

Some patients have found the lack of realism of the animated avatar distracting, which limited the effectiveness of the therapy.

For that reason, a second phase of the project is being launcheda collaboration between Montreal virtual reality company Ova and the Pinel Institute, tocreate more vivid iterations of the patients' descriptions of their inner demons.
