Repressed Memories of Child Sex Abuse

Why childhood sex abuse may cause repressed memories in adulthood, and why victims may take years to come forward.

The human brain is a complex organ. It has nearly full control over the functioning of both the body and the mind. However, a traumatic event can deeply change the way a victim’s brain processes and interprets information. Any profoundly horrifying or life-threatening occurrence – a natural disaster, a battle, or a physical or sexual assault – can scar the mind and alter the operation and structure of the victim’s brain.

Research proves that victims of sexual abuse, particularly childhood molestation, may develop PTSD, guilt, anxiety, depression, and phobias. These can, in turn, lead to relationship and work problems, irrational fears of people, places, or things, or even thoughts of self-harm or suicide. Physical diseases like diabetes and heart disease are also a possible side effect of PTSD. Therefore, as a defense mechanism against these effects, the brain tends to create repressed memories of the occurrence. Therefore, the victim can't consciously remember, preventing any negative effects for as long as the brain can block the memories.

If the sexual abuse victim is a young child at the time, studies have shown that the resultant stress can alter the physical structure of the brain. Researchers note that children physically abused at a young age tend to have smaller amygdala and hippocampi. The amygdala controls a person’s emotions and decision-making; a smaller amygdala means less resistance to emotions like anger or aggression. The hippocampus also controls emotions as well as memory formation. A child with a smaller hippocampus may have learning problems in school, lack control over their emotions, or have memory impairments.

Repressed Memories

Many sex abuse victims claim to have repressed memories of their traumatic experiences, with only bits and pieces filtering through years later – if at all. Psychologists call this “dissociative amnesia”. Repression is a well-documented defense mechanism. Survivors of sexual abuse sometimes use it as a anti-stress mechanism. The experience is so traumatic that the victim cannot bear to remember it without experiencing a similar stress response. Therefore, the brain forcibly makes all memories of the experience repressed memories, preventing the victim from consciously remembering the event, leading the victim to forget it partially or completely.

Danielle Bostick's Story

In November 2014, the Washington Post published a moving essay by Danielle Bostick, whose swim coach, Christopher Huott, sexually abused her from the ages of 7 to 12. Soon after, she had repressed memories of the event, feeling – as a majority of sex assault victims do – that it was safer to downplay, minimize, and ultimately forget the damage she had suffered. It was only the vaguest stirrings of her memory – a “gut feeling,” as Bostick described it – which led her to report the crime to police in March 2014. Huott is now serving a ten year prison sentence.

In another, and even more remarkable story, a 46-year-old Florida woman had repressed memories of being sexually abused as a child when, purely by chance, she moved in next door to her old abuser. When Donald Truluck was in his twenties, he began to rape a six-year-old girl left in his care by her mother and aunt. The abuse continued for six years, sometimes aided by drugs Truluck would administer to the girl. The woman’s brain repressed the horrible memories, but the psychological damage lingered. After she and her husband moved onto Truluck’s property some years ago, she began to have uncomfortable flashbacks. She saw a therapist after developing suicidal feelings. That’s when the memories came flooding back. Authorities arrested Truluck in September 2015.

What you can do about repressed memories

There remains much research to be done. Without a doubt, the battle between skeptics and believers of dissociative amnesia will continue to play out. What is clear, however, is that sexual abuse is highly traumatizing, and each individual reacts differently to it. It is also true that a majority of sexual abuse goes unreported; perhaps due to the way it makes the human mind dissociate itself, and repress its own memories.

If you or a loved one has been sexually abused, even if you have only the vaguest memory of the incident, there are two things you should immediately do; report the incident to police with as specific details possible; and see a counselor or therapist to make your peace with what took place. Sex abuse can be damaging to both yourself and society as a whole. Reporting it to the authorities and seeking mental healthcare will minimize the damage in both arenas.
