Concussion vs. Post-Concussion Syndrome: Why You're Still Struggling Weeks Later

Concussion vs. Post-Concussion Syndrome: Why You're Still Struggling Weeks Later

A concussion is often described as a short-term metabolic injury to the brain — but if you're still dealing with symptoms weeks or even months later, there's more going on than just the initial hit.

At our Kansas City auto injury clinic, Dr. Lance Stevenson, DC helps patients recover from post-concussion syndrome (PCS) by addressing not just the brain, but the multiple body systems involved in persistent symptoms — especially after car accidents or sports injuries.

A Concussion Is a Temporary Brain Injury

During the initial injury, the brain undergoes a neurometabolic cascade:

• ATP (energy) levels drop

• Blood flow becomes dysregulated

• Inflammation and excitatory chemicals build up

• The brain’s ability to self-regulate is disrupted

Most concussions resolve within 22-30 days in adults, and within a few weeks in children — if the systems supporting the brain recover properly.

But when symptoms persist beyond the typical window, we’re no longer just dealing with a “simple” concussion.

Post-Concussion Symptoms Are Often Due to Other Subtypes and Systems

Post-Concussion Syndrome (PCS) refers to symptoms that persist longer than expected — typically more than 3 weeks. These symptoms are often driven by secondary dysfunctions in systems connected to, but not inside, the brain itself.

Common systems and subtypes involved include:

🧠 Cervical Spine Dysfunction

Whiplash, joint restrictions, and muscle tension (especially in the suboccipitals and upper traps) can cause:

• Headaches

• Dizziness

• Neck pain

• Visual disturbances

👁️ Visual and Oculomotor System

Injuries to eye movement coordination (saccades, pursuits, accommodation) can lead to:

• Blurry vision

• Difficulty reading or using screens

• Eye strain

• Fatigue

🎯 Vestibular and Balance System

Disruption of the vestibulo-ocular reflex (VOR) or inner ear function can trigger:

• Dizziness

• Motion sensitivity

• Poor balance

🌡️ Autonomic Nervous System (Dysautonomia)

When the brainstem or vagus nerve regulation is disrupted, patients may experience:

• Lightheadedness

• Heart rate or blood pressure changes

• Exercise intolerance

• Anxiety or overstimulation

🔁 Metabolic and Inflammatory Changes

Some PCS patients develop chronic inflammation, gut dysfunction, or hormonal imbalances that contribute to:

• Brain fog

• Sleep disruption

• Mood swings

• Energy crashes

Why You’re Still Symptomatic

If your only treatment was rest and time, but you're still dealing with symptoms — you’re not alone. Many Kansas City patients come to our clinic saying:

• “I feel like my brain isn’t working right.”

• “I’ve had headaches every day since the accident.”

• “I get dizzy just walking through a grocery store.”

• “My vision feels off, but my eye exam was normal.”

This happens because the concussion set off a chain reaction, and recovery takes more than just waiting it out.

How We Help at Our Kansas City Clinic

Dr. Lance Stevenson, DC provides a full-body, system-based concussion evaluation and care plan that includes:

✅ Cervical spine and joint motion testing
✅ Visual and oculomotor screening
✅ Vestibular function and balance assessments
✅ Autonomic nervous system testing
✅ Coordination of care for gut-brain and endocrine symptoms

Each care plan is customized based on the systems that are still impaired — not a one-size-fits-all protocol.

Stop Waiting. Start Healing.

A concussion may be a short-term brain injury, but post-concussion symptoms can last for months when other systems are left untreated.

At our Kansas City clinic, Dr. Lance Stevenson, DC is known for helping patients from Overland Park, Lee’s Summit, Raytown, and North Kansas City recover fully — even when symptoms have persisted for weeks or months.
