Bad memories can underlie several problems, from post-traumatic stress disorder (PTSD) to phobias. Some evidence suggests it may be possible to block something such as an unwanted memory, but more research about how to forget a memory is necessary.
When an unwanted memory intrudes on the mind, it is a natural human reaction to want to block it out. More than 100 years ago, Sigmund Freud suggested that humans have a defense mechanism that they can use to help manage and block traumatic experiences and unwanted memories.
While more research is still necessary, scientists have started understanding how this may work. Neuroimaging studies have demonstrated which brain systems play a part in deliberate forgetting, and studies have shown that it is possible for people to deliberately block memories from their consciousness.
This article will discuss how people can try to forget unwanted memories.
