ADHD or Trauma? How to Tell When the Symptoms Look Alike

When staying on guard looks like being distracted

After something frightening, the mind can stay switched on long after the danger has passed. Part of your attention keeps scanning the room, the door, the tone of someone's voice. What is left over for the spreadsheet, the homework or the conversation in front of you can feel thin.

From the outside, and sometimes from the inside, that can look like the scattered attention of ADHD. The two have very different roots, though, and telling them apart shapes what kind of support helps most.

Where trauma and ADHD symptoms overlap

The Substance Abuse and Mental Health Services Administration (SAMHSA) describes trauma as an event or set of circumstances that a person experiences as physically or emotionally harmful or life threatening, with lasting effects on their functioning and well-being. SAMHSA notes that many people go on without lasting negative effects, while others have traumatic stress reactions.

The National Institute of Mental Health (NIMH) groups some PTSD symptoms under arousal and reactivity. They include being easily startled, feeling tense or on edge, having difficulty concentrating, having trouble falling or staying asleep, feeling irritable or having angry outbursts, and engaging in risky or reckless behavior. NIMH adds that these symptoms are often constant.

Put that next to the NIMH description of ADHD in adults: difficulty paying attention, restlessness, and acting without thinking. Concentration, restlessness, irritability and impulsive choices can appear in both. The National Center for PTSD, part of the U.S. Department of Veterans Affairs, describes the PTSD version as being jittery or always alert and on the lookout for danger.

How it can look in children and teens

The National Center for PTSD explains that children who are keyed up after trauma may spend time looking for possible threats and become easily startled. They may seem restless or fidgety, or have trouble paying attention and staying organized, which it says can be confused with symptoms of ADHD. Nightmares and sleep problems are also common.

Teens with PTSD begin to look more like adults, but the National Center for PTSD notes they are more likely than younger children or adults to show impulsive, risky or aggressive behavior. NIMH also notes that older children and teens may develop disruptive, disrespectful or destructive behaviors after trauma.

The Centers for Disease Control and Prevention (CDC) adds that symptoms that look like ADHD can sometimes be temporary, and that difficulties with behavior or emotions might be a reaction to stress and change. For a parent, the shape of the story over time is often more telling than any single hard week.

Why the timeline matters so much

ADHD is a developmental condition. NIMH explains that symptoms must begin in childhood, before age 12, and that for adults a diagnosis relies heavily on past reports of behavior, sometimes from family members or school records.

Trauma reactions follow an event. NIMH says PTSD symptoms usually begin within three months of the traumatic event, although they sometimes emerge later, and the National Center for PTSD notes they may not appear until months or years later and may come and go. When trauma happened early in childhood, the two timelines can blur, which is one more reason to take the history slowly.

It can be more than one thing

Sorting out symptoms is not always about picking a single answer. The CDC notes that for some children, symptoms that look like ADHD are better explained by another diagnosis, but many children with ADHD also have another condition. NIMH states that people with PTSD often have co-occurring conditions as well, such as depression or anxiety disorders.

NIMH also notes that PTSD symptoms must be unrelated to medication, substance use or other illness to meet the criteria. In other words, professionals check several possible explanations before settling on one or more. Only a mental health provider can diagnose PTSD, according to the National Center for PTSD.

If you or your child is in crisis or thinking about self-harm, call or text 988, or call 911. Locascio Wellness does not provide emergency services.
