A group of scientists from the U.S., Spain, and the Netherlands has discovered that giving people propofol can cause muddied memory to evoke of specific incidents. The study was published in Science Advances. The study described experiments they carried with volunteers experiencing colonoscopy and what they discovered. Memories can be a curse and a blessing; everyone has rejoiced a moment or two of daydream about pleasant experiences in their history. But most of the people have also felt the ache that accompanies easing traumatic incidents. Fascinatingly, the previous study has shown that when people recall an event, just accessing the memory makes it unlock to revision, and in most of the cases, we do not even understand it. In last few years, medical researchers have concentrated a lot of awareness on the option of taking benefit of such memory revising to eradicate bad memories when they cause psychological disorders like PTSD (post-traumatic stress disorder).
In this new attempt, the scientists’ continued the research by analyzing the option of using a sedative to reduce or remove the clarity of memory. The scientists enlisted the help of 50 volunteers who were earlier planned for a routine colonoscopy that will involve sedation by drug propofol. Around 2 Weeks before the procedure, each participant was told one of two stories that were concurred by an exemplified slide show. After the procedure, the researchers reported that they saw no as such difference in story remembrance by those volunteers who were analyzed straight away after their process, but they did see a decline of 12% in scores by those who were analyzed 24 Hours later. They propose this shows that giving propofol soon after revisiting a memory can hold back bad memories.
On a similar note, recently it was found that exposure to trauma affects the capability to squash bad memories. People encountered to trauma are less capable of suppressing unnecessary emotional memories owing to behavioral and neural disruptions in their brain that might contribute to the development of PTSD. Reportedly, PTSD is differentiated by strong reliving of the trauma that is intrusive, repetitive, and incapacitating. The intrusive nature of such hallmark symptoms indicates that the failure to hold back unwanted memories might be a strong provider to the behavioral manifestation of PTSD.
