A new wave of psychological research is pioneering Virtual Reality (VR) to treat medical conditions from social anxiety to Alzheimer's disease.
Riding a wave of interest in mental health tech, companies creating VR content for treatment are receiving a flood of attention and funding. And, while VR has been used successfully to treat post-traumatic stress disorder (PTSD) since the 1990s, these new programs address a much broader range of conditions. The library of Palo Alto-based Limbix, for instance, includes VR content designed to treat issues including alcohol addiction and teenage depression. Barcelona-based Psious offers treatments for eating disorders.
Today's VR content is primarily designed to aid exposure treatment, a treatment for anxiety disorders in which patients are exposed to the "threats" they're worried about in a safe, controlled environment, eventually learning that the "threats" are not actually very dangerous. For example, someone who fears heights might visit taller and taller buildings under the guidance of their doctor, while someone with PTSD might revisit painful memories.
VR allows doctors to create a safe and controlled environment inside a VR headset. It's a far safer, quicker and less expensive option. Using VR also gives doctors much more control over the intensity (强度) of their patients' experiences, which can lead to better treatment outcomes, said Stephane Bouchard, a professor at the University of Quebec. VR treatment patients can also do things they couldn't do in the real world. "In one of our studies, we asked patients who are afraid of heights to actually jump from a cliff," Bouchard said.
However, not all VR treatment content is created equal. "Some companies show videos of VR environments that are incomplete, untested and definitely haven't been tried out by psychologists," Bouchard said. Clearer rules and standards will make it easier for patients and doctors to identify products that work.
Starting a wildlife conservation center is a necessary important job, but it hardly brings money to its founder and so it is for Jane Thomas. She spent several years (build) the Motley Zoo, and devoted herself to wildlife (protect) in Redmond, Washington, but all money she made was spent straight back on the zoo. She was determined (continue) to do her work, even though there was little money to reward her.
But things changed this year. "As crazy as it sounded, because of my efforts, I received a secret donation: $ 9,000," Thomas said. She decided to use the money was donated by a stranger this year to rescue more animals. She advertised the animal rescue on the street and received much support from public.
Thomas said, "Ever since I advertised the animal rescue on the street, I (attract) many people. Now when I walk on the street, many (passer-by) wave and even shout to me 'I adopted (收养) my dog from you!' I feel (shock) that people treat me (nicely) than ever. "
