hyperarousal, which results in difficulty sleeping, angry outbursts and feeling constantly on guard or jumpy.<\/p>\n<p>\u201cA veteran might be mowing his lawn on a peaceful summer\u2019s day and suddenly the smell of gasoline from the lawn mower will trigger a flashback to a terrifying roadside bomb attack he experienced while serving in Afghanistan,\u201d USC Dornsife alumnus Marat Zanov said.<\/p>\n<p>Russian-born Zanov, who earned a Ph.D. in psychology in 2009, knows what he\u2019s talking about. A former U.S. Air Force captain, he served for six years, during which time he was deployed for six months in hostile territory in Afghanistan\u2019s Parwan province. There, he flew the U.S. flag over his forward operating base (FOB), later donating it to the Department of Psychology at USC Dornsife, where it now hangs on a wall in the main office.<\/p>\n<p>As a military clinical psychologist, Zanov treated many cases of PTSD, as well as a broad range of traditional clinical problems.<\/p>\n<p>The day after leaving the Air Force, Zanov joined friend and fellow psychology alumna Dawn McDaniel at Virtually Better, Inc., a Decatur, Georgia-based research and development start-up, which uses virtual reality technology to treat numerous anxiety disorders including PTSD. There, Zanov is using his insights as a military clinical psychologist, coupled with his personal experience of deployment in Afghanistan, to fine tune the virtual reality environments the company offers to providers treating patients with PTSD and other anxiety disorders.<\/p>\n<p>\u201cSince developing the first virtual reality exposure therapy for the treatment of fear of heights and finding it to be highly effective, we have been using virtual reality technology for a number of different exposure conditions,\u201d said McDaniel, who earned her Ph.D. in psychology from USC Dornsife in 2010.<\/p>\n<figure style=\"width: 350px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/sites\/7\/migration-uploads\/Virtual2-1814.jpg\" alt=\"A photo of a man wearing a VR headshot, holding a controller.

Although McDaniel followed a different path, studying public health and training as a child psychologist, like Zanov she also spent several years in uniformed service, attaining the rank of lieutenant commander during her three years stationed at the Centers for Disease Control in Atlanta, Georgia.<\/p>\n<p>McDaniel now heads up research and development at Virtually Better, while Zanov is in charge of training clinicians to use their products.<\/p>\n<p>\u201cThe big question we had starting out was would being in a virtual reality environment provide the same kind of psychological and physiological reactions as being in the real environment,\u201d McDaniel said. \u201cWe found that we can successfully replicate many real-world scenarios or many people\u2019s memories through virtual reality simulations.\u201d<\/p>\n<p>Repeated exposure to these realistic simulations has been shown to reduce symptoms of PTSD and other anxiety disorders, ranging from fear of flying to arachnophobia.<\/p>\n<p>\u201cWe create a virtual environment where we can expose the patient to previously feared situations and get them comfortable in those environments so they can eventually overcome their impairment,\u201d Zanov said.<\/p>\n<p>The sophisticated software Zanov and McDaniel are using to treat PTSD was developed by a team led by Albert \u201cSkip\u201d Rizzo, director of medical virtual reality at USC Institute for Creative Technologies.<\/p>\n<p>Called \u201cBrave Mind,\u201d it provides a virtual recreation of Afghanistan and Iraq environments.<\/p>\n<p>\u201cWe are a distributor of the Brave Mind program,\u201d Zanov said. \u2018We put together the hardware that supports the USC-developed software. We use this technology to help providers enhance their practice, helping them get their patients closer to overcoming PTSD.\u201d<\/p>\n<p>The program allows clinicians to tailor the virtual reality environment to the patient who can experience being a passenger, a driver, a commander, or a gunner in either a Humvee or an MRAP, both widely-used military vehicles in Afghanistan and Iraq. Alternatively, patients experience being part of a foot patrol in a village or market. The patient can then be exposed to simulated situations, such as an ambush, a roadside mine, or a rocket-propelled grenade attack. They may witness comrades being wounded or killed, civilian casualties or an \u201caerovac\u201d \u2013 a Black Hawk helicopter picking up casualties.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright\" src=\"\/wp-content\/uploads\/sites\/7\/migration-uploads\/Virtual3-1814.jpg\" alt=\"A photo of a woman showing an image on a laptop to another person.\" width=\"350\" height=\"225\" \/><\/p>\n<p>Dawn McDaniel has developed inexpensive Web-based treatments for children suffering from mild anxiety. One is a pirate-themed adventure young patients can use at home with their families.<\/p>\n<p>\u201cWe can tailor those scenarios very closely to patients\u2019 experiences, virtually placing them into traumatic situations they carry in their memories from the theater of war,\u201d Zanov said.<\/p>\n<p>\u201cOver a couple of sessions we fine tune the environment to their specific experience and then repeatedly expose them to it in subsequent sessions.\u201d<\/p>\n<p>By engaging multiple senses, the experience is designed to be as realistic as possible. Patients hold a simulated weapon while wearing a head-mounted display incorporating futuristic goggles with two screens and headphones.<\/p>\n<p>\u201cThe experience is pretty immersive,\u201d Zanov said. \u201cThe patient can see almost in 3D and there is a tracker in the head-mounted displays that shows variations in the environment if they turn their head and look around or look up or down, while the soundtrack they hear through the headphones corresponds to the sounds of the Humvee, ambient street noises and explosions they witness via the displays.\u201d<\/p>\n<p>Standing on a vibrating platform that shakes each time there is an explosion, a shootout or an engine rumbles, provides an additional tactile experience.<\/p>\n<p>To make the experience even more realistic, a scent machine adds an olfactory layer of body odor, garbage, sewage, gunpowder, market spices or diesel fuel. Again, the scents are individually tailored to fit closely with the patient\u2019s experience.<\/p>\n<p>McDaniel and Zanov are now developing mobile apps, software and training applications for use in clinical practice.<\/p>\n<p>McDaniel has also been instrumental in developing affordable online treatments, including a Web-based treatment for mild anxiety in children.<\/p>\n<p>\u201cIf children are experiencing mild anxiety, their family can download a pirate-themed adventure that does all the same things at home we would do clinically in the office for a fraction of the price,\u201d McDaniel said.<\/p>\n<p>\u201cWe ask kids to develop lists of things they\u2019re scared of and categorize them,\u201d she said. \u201cWe then develop small steps toward their main goals. So if they\u2019re scared of spiders they may first go into a room with a spider, then approach the spider, until by the end of the treatment they are putting the spider in a cup and taking it outside.\u201d<\/p>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Marat Zanov and Dawn McDaniel each earned Ph.D.s in psychology at USC Dornsife.
