Encoding Failure refers to the brain's occasional failure to create a memory link. Encoding refers to the brain's ability to store and recall events and information, either short or long-term. This faculty can fail for a number of reasons; trauma or substance use being the most common. When this happens, it can prevent the brain from creating and storing memories. Many of us can identify times in our lives where, due to an accident, traumatic event or substance use, we are unable to remember specific events or actions.
