EMDR: Adapting Trauma Therapy for the Injured Brain

For many people living with persistent post-concussion symptoms, trauma quietly becomes part of the recovery story.

Sometimes it's the trauma of the accident itself. Sometimes it's the months — or years — of living with pain, dizziness, brain fog, anxiety, and a life that suddenly feels unfamiliar. And sometimes it's the experience of repeatedly being told: "Your MRI is normal." "There's nothing wrong." "You should be better by now."

That experience alone can become deeply distressing. In an eye-opening episode of Life After Impact, I spoke with Dr. Michelle Morrissey, one of the country's leading experts in Eye Movement Desensitization and Reprocessing (EMDR). What makes her work unique is that she has spent years adapting EMDR specifically for people with traumatic brain injuries — because she recognized that the standard approach wasn't always safe or effective for this population.

Trauma Doesn't End When the Accident Is Over

Many people assume trauma only refers to catastrophic events. In reality, trauma can accumulate.

For someone recovering from a concussion, the emotional burden often grows over time: loss of work, loss of independence, social isolation, financial stress, fear that recovery may never happen, and repeated medical appointments without answers.

Dr. Morrissey points out that many patients aren't only processing the original injury — they're also processing everything that happened afterward. In some cases, interactions with healthcare providers themselves become part of the traumatic experience when patients feel dismissed or misunderstood.

What Is EMDR?

EMDR stands for Eye Movement Desensitization and Reprocessing. Although many people associate EMDR with moving the eyes back and forth while thinking about a traumatic event, that image barely scratches the surface.

EMDR is an eight-phase therapeutic approach designed to help the brain process experiences that have become "stuck." The goal isn't to erase memories — it's to reduce the emotional charge attached to them so they no longer trigger the same overwhelming physiological response.

As Dr. Morrissey explained during our conversation, the therapy isn't about forcing someone to relive their trauma for an hour. In fact, identifying the memory often takes only a few minutes before the actual processing begins.

Why Brain Injury Changes Everything

This is where the conversation became particularly fascinating. Traditional EMDR often relies on rapid side-to-side eye movements. For many people recovering from a concussion, that's exactly the wrong place to start.

Following a brain injury, the visual system is frequently affected. Rapid eye movements can provoke headaches, increase dizziness, trigger eye strain, or simply overwhelm an already vulnerable nervous system. Rather than assuming every patient should receive the same treatment, Dr. Morrissey developed modifications based on the specific needs of people with brain injuries.

Adapting EMDR for the Injured Brain

Instead of relying on fast eye movements, Dr. Morrissey often substitutes other forms of gentle bilateral stimulation, including:

• Alternating tactile tapping
• Gentle vibrating hand-held tappers
• Alternating auditory tones
• Soft rhythmic squeezing
• Other slower bilateral sensory inputs

Perhaps the most surprising adaptation is speed. While many EMDR therapists are trained using relatively rapid stimulation, Dr. Morrissey's work emphasizes slowing the process down considerably for individuals with brain injuries. She compares it to a trickle charger for the nervous system — rather than trying to flood an already overloaded brain.

The Working Memory Analogy

One analogy from our conversation immediately stood out. Dr. Morrissey compares the brain to a computer. Many people focus on the hard drive — the total amount of storage. But what determines how smoothly your computer runs is actually the RAM, or working memory.

Stress, trauma, unprocessed emotional experiences, and daily overwhelm all occupy working memory. As those demands increase, the brain has fewer resources available for attention, planning, problem solving, and concentration.

Brain fog isn't always just about damaged brain tissue. Sometimes it's also about a nervous system carrying more than it has the capacity to process.

Why Treating Trauma Can Improve Physical Symptoms

One of the most encouraging parts of our discussion was hearing the wide range of improvements Dr. Morrissey has observed after appropriately adapted EMDR. Patients frequently report improvements in:

• Sleep quality
• Mood and emotional regulation
• Stress tolerance
• Cognitive capacity and concentration
• Hyperacusis (sound sensitivity)
• Overall quality of life

That doesn't necessarily mean EMDR is directly treating every symptom. Instead, reducing the brain's chronic stress load may allow the nervous system to function more efficiently overall.

Not Every EMDR Therapist Treats Brain Injury

One of the questions I frequently receive from patients is: "Why did my therapist tell me they don't work with concussions?"

Dr. Morrissey's answer was refreshingly honest. Many therapists recognize that treating brain injury requires additional knowledge beyond standard EMDR training. Rather than practicing outside their expertise, they appropriately refer those patients elsewhere. That's actually a sign of good clinical judgment.

To address this gap, Dr. Morrissey created advanced training programs specifically for EMDR clinicians who want to safely and effectively work with individuals recovering from traumatic brain injuries.

If you've been wondering whether trauma might be playing a role in your recovery — or you've tried EMDR before and didn't see results — you're not alone. A trauma-informed, qualified healthcare professional can help you explore what might be happening and which next steps may be appropriate.
