What Can Cause People to Forget Their Childhood?

No one remembers everything they’ve done throughout their entire life. Even those who have the extremely rare condition called hyperthymesia (or highly superior autobiographical memory) can’t recall every moment of every day they’ve been alive. 

It’s common to forget the names of childhood friends, elementary school teachers, or certain events that took place long ago. But some people have memory gaps that cover several years, or that block their entire childhood.

What could cause someone to experience this type of widespread memory loss?

There are a range of possibilities, including:

• Traumatic brain injury (TBI)
• Alzheimer’s disease
• Parkinson’s disease
• Korsakoff’s syndrome
• Stroke
• Underdevelopment or dysfunction within certain brain areas
• Brain tumor
• Chronic substance abuse

Another potential reason why a person might not be able to remember their childhood is that they have a history of untreated trauma.

Understanding ACEs

Mental health experts use the term adverse childhood experience (ACE) to describe trauma-inducing events that occur prior to a person’s 18th birthday. Examples of ACEs include:

• Physical abuse
• Sexual assault
• Verbal or emotional abuse
• Extreme neglect
• Death of a close friend or family member
• Violence in the home
• Growing up in an unsafe area
• Food insecurity
• Discrimination
• Life-threatening illnesses

Experiences like these can be harmful to anyone at any age. But since a person’s brain is still developing during childhood and adolescence, the damage to young people can be particularly devastating.

A May 2025 study in the journal BMC Public Health found that the long-term effects of ACEs include increased risk of myriad physical, mental, and behavioral problems, such as:

• Anxiety
• Attention-deficit hyperactivity disorder (ADHD)
• Depression
• Cardiovascular and respiratory problems
• Cognitive impairments
• Emotion dysregulation
• Substance use and addiction
• Binge drinking
• Self-harm
• Reduced educational achievement
• Diminished career progression
• Lower income

How Does Trauma Affect Memory?

The long-term impact of adverse childhood experiences can also include memory problems. When asking, “Is not remembering your childhood a sign of trauma,” it’s important to keep this in mind. The many potential causes of trauma-related memory impairments include developmental delays, dissociation, and repression.

Developmental delays

As noted earlier in today’s post, trauma can prevent a young person’s brain from developing properly. The effects of this delayed or disrupted development can include problems with behavior, emotion regulation, and memory.

As described in a March 2019 article in the journal Clinical Psychology, childhood trauma has the potential to cause both structural and functional alterations in three brain areas: the hippocampus, the prefrontal cortex, and the amygdala. These alterations are believed to result from excessive stimulation of the hypothalamic-pituitary-adrenal (HPA) axis, which releases certain hormones in response to stress.

According to the authors of the Clinical Psychology article, the effects of these brain region alterations can include deficits in executive functioning, which includes working memory and cognitive flexibility.

Dissociation 

When a person is in the midst of a particularly traumatic event, their brain may attempt to shield them from the horror of what is happening to them by dissociating. This experience can include:

• Depersonalization, which is the sense of being separated from your mind and body
• Derealization, which is a feeling of unreality, as though you are in a dream or watching your life play out on a movie screen

In addition to shielding a person from immediate pain, dissociation can also prevent them from storing and recalling memories of the traumatic experience. Clinicians refer to this as dissociative amnesia. 

Depending on the type, intensity, and duration of the trauma that a person endures during childhood, they may later have difficulty remembering significant parts of their younger years.

Repression

The concept of repressed memories, which arose out of Sigmund Freud’s work on psychoanalysis in the 1800s, remains a controversial topic among experts today. 

Some believe that the brain can protect a person from ongoing psychological torment by blocking, or repressing, memories of particularly troubling events. Others have questioned this belief, citing a lack of verifiable evidence that memory repression can occur.

Complicating the matter further, some sources use dissociative amnesia and memory repression interchangeably. Richard J. McNally, PhD, addressed the confusion around this topic in a September 2007 article in the journal Mayo Clinic Proceedings.

Signs Your Memory Loss Is Related to Trauma

Is not remembering your childhood a sign of trauma? As we’ve established, it could be—but how can you know for sure?

The best way to identify the root cause or causes of your memory problems is to discuss your concerns with a qualified mental health expert.

If you’re not yet ready to take that step, the following signs could help you decide that it’s time to talk to a professional:

• You have a vague sense that something terrible happened to you at some point in your past, but you can’t summon any details to support this feeling.
• You struggle with feelings of excessive guilt or shame, but you can’t say exactly what these feelings are related to.
• You feel as though you are constantly in danger or under threat, even when there’s no credible suggestion that you are in peril.
• You sometimes have unexpected emotional reactions, which may include panic or dissociation, with little warning or no obvious trigger.
• You’ve had problems forming and maintaining healthy relationships, in part because you find it difficult to be vulnerable or to trust others.
• You have low self-esteem and lack confidence in yourself.
• You’ve been experiencing headaches, muscle tension, stomach aches, and other physical health problems that don’t seem to have an identifiable medical cause.
