Watching “live broadcast” can also cure OCD

  Obsessive-compulsive disorder is a mental illness with compulsive thinking and compulsive behavior as its main manifestations. One type of obsessive-compulsive disorder is that patients will feel a strong feeling of nausea in their hearts after touching objects they consider unclean, which needs to be relieved by washing their hands continuously. Recently, scientists have discovered that patients can alleviate symptoms just by watching others wash their hands, which opens up a new way to treat OCD.
  In our brain, there is a type of brain cells called “mirror neurons”. The neural network composed of mirror neurons is called “mirror neuron system”. There are many specific behavior patterns stored in the mirror neuron system. Some actions can be performed without even thinking about it. That’s why. At the same time, the mirror neuron system also allows us to imitate the actions of others by watching. What’s interesting is that when we watch someone do an action, the corresponding part of the brain responsible for directing the action will become active, just like we do this action ourselves.
  A neuroscientist at the University of Cambridge in the UK speculated that the mirror neuron system might also help us treat OCD.
  He and his colleagues recruited 10 obsessive-compulsive disorder patients. In the first step, the researchers showed each patient something that would make them feel nauseous—such as a bag of vomit, a blood-splattered bandage, or a basket of toilet paper that had been wiped off the stool. In fact, these “filthy things” are fake. The red dot on the bandage is not blood, it is red ink, and the stain on the toilet paper is not stool, but yellow pigment. But the patient believed it.
  Next, the researcher put on latex gloves and touched these “filths” for 15 seconds, allowing the patient to watch them nearby. All patients claimed that they felt a strong nausea when they watched other people come into contact with those “filth”.
  Then, arrange for the patient to watch the researcher wash their hands. All patients reported after watching that they felt much lighter. Interestingly, while watching the hand washing process, the patient kept telling the researchers how to wash their hands, “Hey, wash this side of your hand more.” “Water more between your fingers.” and so on.
  Researchers envision that if OCD patients can alleviate their symptoms by just watching others wash their hands, then in the future we can put videos of OCD patients themselves or others washing their hands in mobile apps and let them watch them when needed.
