Adverse Childhood Experiences and PTSD – What’s the Connection?

Adverse childhood experiences (ACEs) are potentially traumatic events that can occur in the lives of children. They typically involve abuse, neglect, abandonment, and other forms of physical or emotional maltreatment. Adverse Childhood Experiences can have a profound effect on a child’s physical and mental health for years to come, causing long-term emotional trauma, which can lead to post-traumatic stress disorder (PTSD).

What is PTSD?

Post-traumatic stress disorder (PTSD) is a mental health disorder that can develop after someone has been through a traumatic experience.

Common symptoms of PTSD include feeling emotionally numb, having nightmares or flashbacks of the trauma, feeling jumpy or easily startled, and avoiding activities associated with the event.

People struggling with PTSD can also feel depressed and hopeless, and have difficulty sleeping or concentrating.

The most common Adverse Childhood Experiences


Poverty can have a profound effect on children. It can lead to food insecurity and hunger, inadequate housing or homelessness, limited access to health care and educational opportunities, and a lack of clothing or basic necessities.

These factors can then contribute to mental health issues like anxiety and depression, lower self-esteem, and behavioural problems. In some cases it may even cause physical health issues due to a lack of proper nutrition or medical treatment.

Emotional Abuse

Emotional abuse is a form of psychological maltreatment that involves belittling, shaming, name-calling, and other forms of verbal aggression. It can cause long-term damage to a child’s self-esteem and can lead to feelings of anxiety, depression, and worthlessness.

Physical Abuse

Physical abuse is any kind of intentional physical violence used against a child. It includes slapping, hitting, kicking, burning, or any other type of physical injury inflicted on the child by an adult or older child who is in a position of power or authority over them.

Sexual Abuse

Sexual abuse refers to any kind of sexual contact between an adult and a minor which does not involve consent from the minor. This includes fondling, rape, and exposing minors to sexual activities such as pornography or prostitution.


Neglect is the failure to provide basic needs for a child like food (undernourishment), shelter (homelessness), clothing (inadequate clothing) education (lack of education) medical care (lack of proper health care), and emotional support (apathy toward their well-being).


Abandonment is similar to neglect but more severe in nature as it involves leaving a child alone without any supervision or means of support for an extended period of time without any explanation or indication of when they may be returned home safely.

Witnessing violence

Witnessing violence is another form of adverse childhood experience. This can involve seeing a family member or parent get physically or verbally abused, or hearing about violent acts from the media or friends.

The effects of witnessing such violence can be psychological in nature, as it can create feelings of insecurity and fear, lead to anxiety and depression, decrease self-esteem and academic performance, and cause behavioural issues like aggression.

In some cases it may also lead to physical health problems due to the stress it causes.

Having a parent with mental illness

Having a parent with mental illness can be very difficult for children and young adults. It often brings about strong feelings of shame, guilt, and isolation, as well as confusion about their own emotions and behaviors.

This can make it difficult for the individual to form trusting relationships due to a fear of judgement or rejection from others.

Mental illnesses such as depression, anxiety and bipolar disorder may also cause mood swings that can be hard for the child to keep up with. All of this can have a significant impact on self-esteem and lead to mental health issues in the future.

Having a parent who abuses substances

Having a parent who abuses substances can have a significant impact on a child’s life. Not only may there be financial instability, but emotional and physical neglect can also be an issue for these children.

Furthermore, it puts them at increased risk of developing substance abuse problems themselves due to environmental factors and/or genetics.

In addition, the lack of stability in their home life can lead to feelings of fear and insecurity, which may manifest as social anxiety or difficulty forming trusting relationships with others.

The Impact of Adverse Childhood Experiences

Adverse childhood experiences can have a profound effect on an individual’s development and mental health.

Adverse childhood experiences can lead to changes in the structure of the brain, namely in areas associated with decision-making and cognitive processing. Such changes can compromise an individual’s ability to think critically, process complex information, and make sound decisions. These impairments can have a detrimental effect on an individual’s long-term mental health and overall development.

They may also lead to an increased risk of depression and anxiety, as well as impairing an individual’s ability to cope with stress. This can cause individuals to seek solace in unhealthy behaviors such as smoking or binge drinking, which may exacerbate the problem.

Furthermore, these experiences may weaken an individual’s ability to regulate their emotions, leading them towards substance misuse as a coping mechanism.

Adverse Childhood Experiences and PTSD

Adverse childhood experiences lead to an increased risk of developing Post-Traumatic Stress Disorder (PTSD).

Studies show that individuals who experienced trauma in their childhood are more likely to develop PTSD when exposed to a traumatic event later in life. This is because the trauma experienced in childhood can inhibit the development of resilience and coping mechanisms, leaving the individual more vulnerable to psychological distress.

Furthermore, ACEs can alter the structure and functioning of the brain, impacting the functioning of the Prefrontal Cortex, which plays a role in controlling emotions and regulating responses to stress.

Additionally, studies have found that individuals with a history of childhood trauma have lower levels of important neurotransmitters like serotonin, dopamine and norepinephrine, which can further impair an individual’s ability to respond appropriately during times of distress and recovery from traumatic events.

What can you do if you think you have developed PTSD after experiencing Adverse Childhood Experiences?

Talk to a mental health professional: Having an open and honest conversation with a qualified therapist or counsellor can be highly beneficial for someone dealing with PTSD as a result of adverse childhood experiencfes. A mental health professional can provide support, resources, guidance and strategies to help the individual cope more effectively.

Practice self-care: Taking time for oneself and incorporating activities that promote wellbeing is critically important for healing from trauma. This includes engaging in regular physical activity, getting adequate rest, eating nutritious meals and connecting with others in meaningful ways.

Utilize relaxation techniques: Breathing exercises, progressive muscle relaxation and calming music can help an individual to relax and feel more grounded during times of distress or intense emotions.

Seek out support groups: Many people find great comfort in connecting with others who are facing similar circumstances, as it allows them to share experiences, gain understanding and cultivate genuine friendship.

Experiment with different forms of expression: Whether through journaling, art or music therapy—exploring different means of expressing emotions can be incredibly therapeutic on the journey of recovery from adverse childhood experiences, PTSD and their subsequent effects on mental health.

Final Thoughts about Adverse Childhood Experiences and PTSD

Research has shown that individuals who have experienced adverse childhood experiences are more likely to develop PTSD when exposed to a traumatic event later in life.

This is because ACEs can affect an individual’s brain structure and cognitive functioning, reducing the activity of the Prefrontal Cortex, as well as resulting in lowered levels of important neurotransmitters like serotonin, dopamine and norepinephrine.

This can make it more difficult for these individuals to regulate emotions, respond appropriately in times of distress, and recover from traumatic events.

If you or someone you know has experienced adverse childhood experiences and developed PTSD, it is important to seek help. Lean on your support network , whether that is family, friends, or a mental health professional. Talk about your experiences and allow yourself to grieve. This is an important part of the healing process.

And finally, be patient with yourself. Healing takes time and it is not always linear. There will be good days and bad days. Step by step, you will make progress, and you will finally come to terms with what you have been through and find peace.
