How Trauma Impacts Memory?

How trauma impact memory? It can be difficult to process and understand. This blog will explore how trauma affects memory and what we can do to heal.

It’s well known that severe trauma can lead to post-traumatic stress disorder (PTSD), a condition that is characterized by flashbacks, nightmares, anxiety, and avoidance of anything that might trigger memories of the event. But what is less well known is that trauma can also impact our ability to form new memories and can lead to memory problems long after the traumatic event has occurred.

Trauma affects both the body and the mind, and it can have short- and long-term effects on our thinking, feeling, and behavior. The impact of trauma on memory is one of the long-term effects.

There are several ways in which trauma can impact memory. First, trauma can cause changes in the way we store memories. Normally, our brains store memories in a linear fashion—we remember events in the order in which they occurred. But when we experience trauma, our brains sometimes store memories differently. For example, people with PTSD often have trouble with “sequential memory,” or remembering the order of events. They may also have trouble with “contextual memory,” or remembering information about where they were or what they were doing when a particular event occurred.

Second, trauma can cause changes in our “implicit” or “procedural” memories—the memories that help us do things without thinking about them, like riding a bike or tieing our shoes. These types of memories are stored in a different part of the brain than our explicit or declarative memories (like remembering what we had for breakfast), and they are usually not affected by trauma. However, some research suggests that people with PTSD may have trouble forming new implicit memories, and that this may contribute to their symptoms (for example, feeling “on edge” all the time).

Third, trauma can lead to problems with “source memory”—our ability to remember where we learned certain information or where we experienced certain events. This type of memory relies on a part of the brain called the hippocampus, which is especially sensitive to stress hormones like cortisol (which are released when we experience trauma). Research shows that people with PTSD often have trouble with source memory—for example, they may remember an event but not where or when it happened. This type of memory problem can be especially frustrating for people with PTSD because it can make it difficult for them to separate their current reality from their past experiences

What is Trauma?

Trauma is an emotional response to a terrible event like an accident, rape or natural disaster. Immediately after the event, you may feel frightened, confused, and helpless. Even if you aren’t physically harmed, it’s not unusual to feel shaken up or numb. These reactions are normal.

In the days or weeks that follow, you may have intense emotions, feel disconnected from other people and have trouble concentrating or sleeping. These are common signs of post-traumatic stress disorder (PTSD). Most people who go through a traumatic experience have some of these symptoms for a while. But most will get better over time with support from friends and family plus self-care. A small number of people will develop long-term PTSD.

What is Memory?

Memory is our ability to encode, store, and recall information. It’s what allows us to remember past experiences and learn from them.

There are three different types of memory:

1. Sensory memory: This is when information from our senses (sight, smell, sound, taste, and touch) is stored in our brain for a very short period of time (usually just a few seconds).

2. Short-term memory: This is when information is stored in our brain for a little longer (up to about 30 seconds). We can increase the amount of information we can hold in our short-term memory by repeating it to ourselves or using mnemonic devices (associating it with something else that we know).

3. Long-term memory: This is when information is stored in our brain indefinitely. We can access this information at any time.

How Does Trauma Impact Memory?

Memory plays a critical role in our ability to function on a day-to-day basis. It allows us to remember important information, such as our address, phone number, and the names of our loved ones. It also helps us remember past experiences, both good and bad.

Traumatic events can have a significant impact on our memory. Often, people who have experienced a traumatic event will have difficulty remembering the details of what happened. This is known as memory fragmentation. In some cases, people may not be able to remember the event at all, which is known as dissociative amnesia.

There are several theories about how and why memory fragmentation occurs after a traumatic event. One theory suggests that the brain is overwhelmed by the experience and cannot process all of the information. This can lead to gaps in memory or a failure to store certain memories properly. Another theory suggests that the brain may actively suppress memories of the event in order to protect oneself from further trauma.

Whatever the cause,memory fragmentation can make it difficult for people to cope with their trauma in a healthy way. It can also make it difficult for people to participate in trauma-focused treatments, such as therapy or eye movement desensitization and reprocessing (EMDR).


There is no one definitive answer to this question. The impact of trauma on memory can vary greatly from person to person. Some people may experience very little impact, while others may struggle with memory problems for years afterwards. The type and severity of the trauma, as well as a person’s individual coping mechanisms, can all play a role in how trauma affects memory.
