We’re all carrying around some cringe-inducing memories that we’d rather forget. But for those suffering Post-Traumatic Stress Disorder (PTSD), recalling certain memories can provoke fearful, emotional experiences. By the same token, some memories can remind those battling drug addiction of the rewarding effects of the drug and trigger a relapse. Researchers at Canada’s Western University have found a way to effectively block these types of memories that could lead to better treatments for both conditions.
Though often associated with exposure to war, Post-Traumatic Stress Disorder
(PTSD), is a severe anxiety disorder which can arise following exposure to any
event which has caused psychological trauma. Those who suffer from PTSD are often subjected to re-living the source of their despair through nightmares and flashbacks, and current treatment results in only occasional success. However, researchers at Stanford University appear to have alleviated PTSD in mice while the rodents slept, by using a new technique which may prove applicable for humans in the future.
An old saying tells us not to dwell on an unpleasant event. A new clinical study suggests the saying has both psychological and neurological support for its validity. Along with his advisors, Thomas Ågren – a doctoral candidate in psychology at Uppsala University in Sweden – has shown that it is possible to erase newly formed emotional memories from the human brain.
