While executive function difficulties are most commonly associated with attention-deficit hyperactivity disorder (ADHD), traumatic stress can also cause them. In addition to nightmares and flashbacks, people who have experienced trauma may also find it difficult to concentrate, remember things, and get organized.

These cognitive effects of trauma might be mistaken for ADHD, and some people may have both ADHD and post-traumatic stress disorder (PTSD). It’s important to understand how these conditions differ, and how trauma and executive function are linked.

This article will explore:

What executive function is.
How trauma can impact the brain, including its executive functions.
Different links between trauma, PTSD, and ADHD.
Treatment options for trauma and impaired executive function.

What Is Executive Function?

Executive function is the set of cognitive skills that enable us to pay attention, carry out tasks, complete our goals, and stay organized. Our executive function skills can be categorized into the following types:^[1]

Attention: Being able to focus your mind on a particular thing.
Working memory: Being able to hold, manipulate, and use information over a short period of time.
Sustained attention: Maintaining your attention on one thing for a prolonged period.
Inhibition: Being able to ignore or repress irrelevant information to focus on the task at hand.
Flexibility: The ability to switch between tasks or lines of thought.
Planning: Being able to develop and carry out strategies for future goals.

When these skills are impaired, it can cause issues in many areas of everyday life and make the following more difficult:

Planning ahead
Managing time and tasks
Regulating emotions
Staying focused

This can lead to being labeled as messy, disorganized, or unreliable when you are trying your best.

Trauma and Executive Function: How Does Trauma Impact the Brain?

Research shows trauma impacts the brain in several ways, particularly if the trauma occurs in childhood when the brain is still developing.^[2] Some of the main impacts include:^[1]^[2]

Physical changes to brain structure, and therefore, cognition.
Difficulties in switching attention from one thing to another.
Memory disturbances such as gaps in memory of everyday events and personal history.
A disproportionate focus on trauma-related memories and thoughts.
Frontal lobe impairments, causing problems with planning, problem-solving, impulse control, and repressing distractions.
A lack of enthusiasm, motivation, and care for things.
Difficulties with learning, storing, and recalling information that is written or spoken.

What Are the Links Between Trauma, PTSD and ADHD?

Executive dysfunction is characteristic of ADHD, a neurodevelopmental disorder impacting about 2% of adults.^[3] Traumatic stress and ADHD impact the same areas of the brain.

Some people are misdiagnosed with one of these conditions, and others with both. There’s also some evidence that trauma can develop into ADHD if it occurs in early childhood.^[3]

We’ll now explore these links to demonstrate how the two conditions are connected and how they’re different:

PTSD vs ADHD

It’s easy to confuse ADHD and PTSD because some of their symptoms overlap, including:3

Problems with concentration.
Seeming faraway and not listening.
Being easily distracted.
Disorganization.
Restlessness and difficulty sleeping.

However, there are some symptoms of PTSD which do not appear with ADHD on its own. These PTSD symptoms include:^[2]

Intrusive thoughts.
Flashbacks.
Nightmares.
Sleep disturbances.
Changes in memory and concentration.
Hyperarousal (being easily startled and alert to potential dangers).

In contrast, ADHD symptoms can be categorized into three groups:

Inattention.
Hyperactivity.
Impulsivity.

These symptoms can make it really difficult for people with ADHD to remember information, focus their attention, and complete daily tasks. They might feel restless and seem to act without thinking first.^[3]

Identifying co-existing PTSD and other mental health conditions is crucial for planning effective ADHD treatment. Only treating one condition can leave the other one to get worse, which often makes treatment ineffective. A full medical assessment can identify which conditions are behind which symptoms so a holistic approach can be taken to recovery.

Can Trauma Cause ADHD?

Up to 17% of children who have experienced trauma meet the criteria for ADHD, and adults who have ADHD are seven times more likely to have PTSD.^[3]

Experts think a combination of factors may cause ADHD, including genetics and brain structure. However, emerging research suggests that childhood trauma can also contribute to ADHD.^[3]

This is because long-term childhood abuse, neglect, or trauma can create a perpetual state of stress. Supportive, healthy relationships with parents and caregivers can act as a buffer for children who experience something traumatic. This can help reduce the physiological stress response in the brain.^[3]

When these relationships aren’t there, stress can become toxic and impact child brain development. This is called “toxic stress,” and it’s when the body’s stress management system stays switched on for a prolonged period of time.^[3]

This can impact several parts of the brain, resulting in executive dysfunction, symptoms of ADHD, and mood disorders. In particular, toxic stress overactivates the parts of the brain responsible for fear, anxiety, and impulsivity, and prevents those involved with reasoning, behavioral control, and planning from developing properly.^[3]

It’s important to note that not everyone who experiences trauma will have impaired executive function. Although between 50-60% of people will experience serious trauma over the course of their lives, only 5-10% will develop post-traumatic stress disorder (PTSD).^[1]

Experts suggest this is because some people are predisposed to developing PTSD if they already struggle with attention, memory, and executive function before the trauma occurs.^[1]

Treating Executive Dysfunction and PTSD

As we’ll explore, any trauma treatment should be personalized to your preferences and goals. Whether you choose therapy, medication, or a combination of the two, there are several ways to address executive dysfunction caused by trauma.

Counseling and Psychotherapy for Trauma and Executive Function

Whichever counseling or therapy you receive, the approach and the therapist should be informed by person-centered principles. This is especially important for people who have experienced trauma. Treatment that ignores your control or your preferences can risk retraumatizing you.

Treatment outcomes also tend to be better when you are included in the decisions about your care.^[4]

Therapy options for treating trauma and executive dysfunction include:^[4]

Trauma-focused therapy is a highly recommended treatment option for people who have experienced trauma, as clinicians undergo specific training. They know how to explore things with you slowly and may guide you through nervous system regulation strategies, if needed.
Eye-Movement Desensitization and Reprocessing (EMDR) is an alternative type of trauma-informed therapy that combines talking therapy with certain bilateral stimulation techniques. These include holding a traumatic memory in your mind while moving your eyes from side to side or continuously tapping the left and right sides of your body one after another. These actions are thought to reduce the emotional strength of difficult past events and PTSD symptoms.
Cognitive behavioral therapy for PTSD (CBT for PTSD) is another evidence-based therapy for treating people who have experienced trauma. This is highly guided work, which may suit people who don’t want to delve deeply into past experiences. Instead, CBT for PTSD provides actionable support for emotional regulation and for challenging thoughts and behavior that make concentration after trauma worse.

Not all therapies will treat your executive dysfunction directly. As it may be one of many symptoms caused by trauma, some therapies will take a broader approach to address all your symptoms.

Nervous system regulation might include things like paced breathing, grounding exercises that use your five senses, or gentle movement to help your body come out of fight-or-flight. A therapist can help you find which of these work for you.

Medication Options for Trauma and Executive Function

Many people with brain fog, attention problems, and “trauma brain” symptoms from post-traumatic stress look into medication. This can be a helpful treatment option if symptoms are severe, but not everyone needs medication. Speaking to your primary care doctor can help you figure out whether you should try psychotherapy first, or start taking medication right away.

If you are prescribed medication for trauma and executive function, it’s likely to be one of the following three, which are all associated with good clinical outcomes:^[4]

Fluoxetine: An SSRI medication often used for major depression, obsessive-compulsive disorder, and PTSD. Due to its long half-life, fluoxetine rarely causes severe withdrawal symptoms.
Venlafaxine: An SNRI medication commonly used to treat anxiety disorders, including PTSD. As it has a shorter half-life, its withdrawal symptoms can be more noticeable.
Paroxetine: An SSRI medication typically used for anxiety, depression, and PTSD, associated with stronger withdrawal symptoms than other options.
