Mild Traumatic Brain Injury (MTBI)

A “mild” traumatic brain injury doesn’t always feel mild and shouldn’t be dismissed as such especially when symptoms don’t resolve.

MTBI, commonly called a concussion, occurs when the brain is jolted or shaken inside the skull. This can happen during sports, falls, car accidents, whiplash injuries, or even incidents where there was no direct blow to the head. Many people are told their injury is “mild” because imaging is normal or there was no loss of consciousness yet symptoms can linger for months or years.

At Peak Brain and Body, we don’t define concussion severity by scans alone but by its impact on you. We look at how the brain is functioning now and why recovery may have stalled.

Our goal is to help your brain restore efficiency, stability, and resilience, so symptoms resolve and confidence returns.

Does This Sound Like You?

  • Headaches or head pressure that didn’t exist before the injury
  • Dizziness, vertigo, or balance problems
  • Sensitivity to light, noise, or busy environments
  • Feeling mentally “foggy,” slowed down, or easily overwhelmed
  • Trouble concentrating, multitasking, or remembering information
  • Fatigue that worsens with mental or physical activity
  • Irritability, anxiety, or mood changes since the injury
  • Sleep that feels unrefreshing or disrupted
  • Being told “it was just a mild concussion” but not feeling back to normal

If symptoms linger or flare with activity, your brain may not have fully recovered even if the injury happened years ago.

What Actually Drives Ongoing MTBI / Concussion Symptoms

Persistent concussion symptoms are rarely caused by a single issue. Most cases of mild traumatic brain injury involve multiple brain systems that haven’t fully recalibrated after injury.

1. Brain Processing & Sensory Integration

After a concussion, the brain routinely struggles to efficiently process:

  • Visual input
  • Balance and spatial awareness
  • Head and body movement
  • Sensory information from the environment

When these systems are out of sync, symptoms such as dizziness, headaches, motion sensitivity, and cognitive fatigue often appear especially in busy or visually demanding settings.

2. Nervous System Regulation

Concussion can disrupt the nervous system’s ability to regulate:

  • Heart rate
  • Blood pressure
  • Blood flow to the brain
  • Stress response

This may lead to symptoms such as lightheadedness, fatigue, palpitations, exercise intolerance, or feeling worse when upright or active.

3. Energy & Metabolic Stress in the Brain

Following injury, the brain often enters a temporary energy crisis. If recovery is incomplete, the brain may continue to struggle with:

  • Efficient energy production
  • Tolerance to mental or physical effort
  • Sustaining focus without symptom flare-ups

This is why pushing through symptoms often backfires and you feel worse.

4. Inflammation & Immune Response

Brain injury can trigger prolonged inflammatory and immune responses that affect:

  • Headache frequency
  • Cognitive clarity
  • Mood and emotional regulation

If inflammation remains elevated, it can interfere with the brain’s ability to heal and adapt.

5. Sleep & Recovery Disruption

Sleep is essential for brain repair and removal of inflammatory wastes. After concussion, it’s common to see:

  • Difficulty falling or staying asleep
  • Unrefreshing sleep
  • Changes in sleep timing

Poor sleep slows neurological recovery and amplifies symptoms like brain fog, irritability, and fatigue.

6. Neck & Cervical Involvement

Many concussions involve whiplash-type forces, even without a direct head impact. We often see individuals diagnosed with whiplash who were never told they suffered a concussion as well. Dysfunction in the neck can contribute to:

  • Headaches
  • Dizziness
  • Visual disturbances
  • Balance issues

This component is frequently overlooked but critical to recovery.

7. Previous Concussions or Brain Stress

A history of:

  • Prior concussions
  • Incomplete recovery
  • Chronic stress or neurological strain

can increase the likelihood of persistent symptoms after even a mild traumatic brain injury.

How We Evaluate

We don’t guess and we don’t rely on imaging alone as it’s routinely normal. We evaluate how your brain is functioning in real-world conditions.

Functional Neurology Evaluation

  • Eye movement and visual tracking
  • Balance and coordination testing
  • Dual-task performance
  • Head and neck assessment
  • Nervous system regulation (autonomic testing)

These tests reveal where the brain is working harder than it should.

Functional Medicine Assessment

We assess factors that influence recovery, including:

  • Inflammation
  • Energy production
  • Sleep quality
  • Nutrient status
  • Hormonal or metabolic stress

Targeted Testing (Only When It Changes Decisions)

Labs or additional testing are used selectively to guide care not as a blanket protocol.

Report of Findings

You receive a clear explanation of:

  • Why symptoms are persisting
  • Which systems are involved
  • What can be improved
  • How progress will be tracked

Your Personalized Care Path

Your care plan is determined by your evaluation results. Most patients follow one of three paths:

Neurology-Focused Path

Best when symptoms are driven primarily by:

  • Visual or balance processing issues
  • Nervous system regulation problems
  • Brain-based inefficiencies

This path uses targeted neurological-based exercises to improve brain performance and symptom tolerance.

Functional-Medicine-Focused Path

Best when contributors include:

  • Inflammation
  • Sleep disruption
  • Metabolic or nutrient issues
  • Hormonal stress

This path supports the internal environment the brain needs to heal.

Combined Brain-Body Path (most common)

Most patients benefit from an integrated approach to mild traumatic brain injury, combining:

  • Brain-based rehabilitation
  • Nervous system regulation
  • Sleep optimization
  • Inflammation and metabolic support

This coordinated model produces the most consistent and lasting recovery.

What Makes Our MTBI Care Different

  • We treat function, not just imaging
  • We specialize in persistent and complex cases
  • We don’t rush recovery or tell you to “just rest” indefinitely
  • We personalize care based on objective testing
  • Led by Dr. Spencer Zimmerman, with advanced training in functional neurology and functional medicine

Safety

Care is always paced below symptom thresholds to prevent setbacks. If red flags arise such as worsening neurological symptoms or concerning changes we coordinate care or refer appropriately.

FAQs

Is a mild concussion supposed to last this long?

While some individuals’ symptoms resolve quickly far too many people will continue with persistent symptoms that are common and treatable.

Yes. Symptoms can evolve over time but you should have some symptoms within 72 hours of the injury.

No. Pushing often prolongs recovery. We build tolerance safely.

For mTBI and concussion, in-person care provides superior results and care needs to be in our Wesley Chapel office.
