There are some new technologies that can be helpful in the treatment of OCD, as well as some older technologies that are useful to this day.
One burgeoning area being investigated is virtual reality (VR). VR can be helpful in assisting individuals who are initially fearful of trying to do an exposure.
For example, if you have a fear of harming your child, then it could be possible for the therapist to first make a VR scenario of a child in a room, and you can walk into the room and play with the child. As time in the VR goes on, various things can be added to the room, such as a knife and a gun and a grenade, and so on.
As these things are added, the person can test whether you would actually go and use one of these weapons and harm the child. Because people with OCD would likely be the last people to actually purposely harm someone about whom they have obsessions, you will learn that even with the means to harm your child, you will not do it.
Then you can move on to actual exposures with your child (of course, it is not recommended to have military weapons around children because they might get a hold of them). Your exposures can involve sitting near your child or having your child in the kitchen with you while you are using a knife to slice food, and so on. This is a great way to use some modern technology to assist in therapy.
An older piece of technology that is still useful is tape players, or now, digital recorders. Many therapists have people write out the scenarios of what they fear and then record that onto a recorder. Then the person is to listen to that scenario over and over again until their anxiety about the scenario decreases. The goal is to start to realize that the scenario, which people often tend to try to suppress or avoid, is so out of the realm of possibility that there is no need to avoid it. Plus, as they listen to it, their fear of it actually decreases instead of increases.
One other recent technology tool is called telehealth. Telehealth is a camera and microphone system that can be used to record therapy sessions in remote locations. Rural hospitals or clinics need only a telephone line and some video equipment, and they can see and communicate with doctors in other locations to do therapy or to get consultations on therapy cases.
As the technology improves, therapists will be able to reach more and more people in rural locations who may not have access to specialists in OCD.
