BBC News's video: Using virtual reality to diagnose Alzheimer s disease BBC News

Scientists are testing the possibility of using virtual reality (VR) to help diagnose Alzheimer's disease. Pen and paper tests date back to the 1940s and are still one of the markers that may be used for diagnosis today. With no single definitive way to confirm the disease, a combination of different tests and investigations are usually carried out by health professionals. Researchers, at University College London, are testing if VR can help confirm an early diagnosis of the disease before it reaches the severe stages of dementia.
