Paranoia 'reduced with virtual reality' - BBC News
Virtual reality has been used to help treat severe paranoia.
Patients who suffered persecutory delusions were encouraged to step into a computer-generated Underground train carriage and a lift.
The simulations allowed the study's 30 patients to learn social situations they feared were actually safe.
The research at Oxford University, published in the British Journal of Psychiatry, was funded by the Medical Research Council.
Members of one group of patients were told to use their normal defensive behaviour, such as avoiding eye contact.
The rest of the patients were encouraged to lower their defences and try to learn they were safe by approaching computer characters (avatars) and standing toe-to-toe or staring at them.
