The team said one of the most striking observations they had made about sufferers was the variation between what sparks their symptoms.
"All the patients are very different and some environments might trigger symptoms for some patients whilst other environments might trigger symptoms for others," Dr Powell said.
"So by using virtual reality (VR) we can have vast flexibility over the different types of environments that we can show to patients and we can find out what their individual triggers might be and then tailor specific rehabilitation therapies."
