Reasons why you don't remember your childhood trauma or have lots of memory gaps

Protective mechanism: The brain has a strategy of dissociating stress, trauma and hurtful memories in order to protect itself from extreme anxiety. Sometimes due to this protective mechanism, we fail to remember our childhood trauma or face a lot of memory gaps when we try to remember the difficult times of our lives.

Neurobiological impact: Traumatic experiences can sometimes alter the functioning of the brain, leading to memory gaps. The high level of stress hormones – Cortisol – can interfere with the working of the brain and the way it encodes experiences.

Developmental: Childhood trauma happens to us at an age when the brain is still at a developing stage. Hence, sometimes the brain is not able to store the experiences as intricately as it can store adulthood events.

Survival mode: During traumatic events, we often enter into the survival mode where we narrow our focus down to the immediate threat at hand. Hence, the brain fails to focus on how to encode the experiences into long-term memory.

Defense mechanism: When we are overburdened with overwhelming thoughts, the brain uses defense mechanisms such as repression or suppression to deal with the emotions.
