People with TBI may not remember the injury itself. In this case, the brain has not stored the injury as a memory or series of memories. People may remain confused and unable to store memories for some time after the injury. The loss of memory from the moment of TBI onward is called post-traumatic amnesia. It can last from a few minutes to several weeks or months, depending on the severity of brain injury. The best way to learn about the injury is to ask family members, friends, or medical personnel who may have objective information.
After a moderate to severe TBI, you may have more trouble remembering things from day to day. One or two medicines may be worth trying ask your doctor. Using compensatory strategies is the best way to tackle memory problems and still get things done. This approach uses memory devices that we all use to make up for limited memory storage in the brain e. Traumatic brain injury in the rat: characterization of a lateral fluid-percussion model.

The short answer is that old memories are stored differently in the brain from new memories. Information from before the brain injury may be forgotten.
For most people with brain injuries this gap in memory from before the injury will range from a few minutes to a few months. This type of memory loss from before the injury is known as retrograde amnesia.
Memories laid down well before the period of retrograde amnesia are likely to be retained well. Problems with memory for information learned after the injury are known as anterograde amnesia, and for most people these problems are likely to be a bigger nuisance and handicap than the memory loss that predates the injury.
Memory problems can destroy a person's sense of identity and continuity. The inability to remember events and emotions can leave people without a sense of the passage of time or of their own narrative and progression as a person. This is on top of the everyday practical difficulties with planning and organisation. There are no easy answers for memory difficulties and it is unrealistic to expect lost function to be regained. However, there are simple, practical steps that can make a huge difference.
Our factsheet Coping with memory problems - practical strategies PDF provides comprehensive strategies in an easily accessible form. Memory is not technically one single skill; there are lots of different types of memories stored across the brain and different ways of categorising them. Often, people refer to memories in two broad categories: short term and long term. The basic stages of getting information from short-term to long-term memory are initially taking information in, storing it and retrieving it when needed i.
Different parts of the brain are involved in these stages, for instance the hippocampus is a part of the brain involved in storing long-term memories. Long-term memories have had time to undergo each stage and be stored properly through a process known as consolidation.
Day-to-day memories, on the other hand, are new information that have not had a chance to undergo this process of consolidation. A brain injury can affect any of the stages involved in this process, therefore disrupting memory storage and leading to poor recollection of the information.
Personal memories, known as anecdotal memories, can and do often return after brain injury. Sometimes this can take place over the course of the initial recovery period, while other memories may take weeks, months or even years to gradually return.
Some memories can be encouraged to return by looking at photographs, personal objects or listening to music relating to the memory. Sadly, there may be memories that do not return directly to you, or memories that return but are not as clear as they used to be.
It is perfectly normal to grieve for this loss. So does remembering what you did on the weekend. Spatial memories. These involve remembering pathways and routes. Examples include memorizing your way home from work or being able to visualize where everything in your room is from memory.
Your hippocampus also converts short-term memories into long-term memories. Secondary Effects of Hippocampus Damage The hippocampus plays a vital role in encoding memory. Anterograde Amnesia.
