Cognitive Issues After Concussion: Why Your Brain Feels Off — and How to Recover
After a concussion, most people expect a headache or some dizziness — but feeling like your brain doesn’t work right is often the most frustrating and misunderstood part of the injury.
If you’ve been struggling with brain fog, poor memory, mental fatigue, or trouble focusing after a car accident or head injury, you’re not alone. At our Kansas City clinic, Dr. Lance Stevenson, DC specializes in identifying and treating the underlying causes of cognitive dysfunction following concussions.
Common Cognitive Symptoms After Concussion
Even a mild traumatic brain injury (mTBI) can disrupt the brain’s ability to process and organize information. Patients often describe:
Brain fog — feeling mentally sluggish or slow
Short-term memory problems — forgetting conversations, appointments, or tasks
Difficulty focusing — especially in noisy or busy environments
Trouble multitasking — unable to juggle more than one thing at a time
Slowed mental processing — it feels like everything takes more effort
Word-finding difficulty — “I know what I want to say, but I can’t find the word”
Mental fatigue — cognitive tasks leave you drained or overwhelmed
Why Does Concussion Cause Cognitive Problems?
A concussion creates a neurometabolic crisis in the brain:
ATP (energy) production drops
Brain cells struggle to communicate
Neuroinflammation increases
Blood flow regulation is impaired
These changes affect the frontal and temporal lobes — key areas for executive function, attention, memory, and language. Even without visible damage on imaging, your brain can be underperforming in critical areas.
If left untreated, this can lead to persistent post-concussion cognitive symptoms, especially when combined with:
Poor sleep
Vision or vestibular issues
Autonomic dysregulation
Emotional stress or overstimulation
Lack of appropriate rehab
Cognitive Load and Mental Fatigue
After a concussion, even simple tasks can feel overwhelming. That’s because your brain is using more effort to do less — especially if other systems like vision, balance, or posture aren’t functioning smoothly.
This mismatch leads to:
Quick mental exhaustion
Frustration at work or school
Trouble processing conversations
Anxiety in crowded or stimulating settings (e.g., grocery stores, meetings)
What We Do at Our Kansas City Concussion Clinic
At our clinic, Dr. Lance Stevenson, DC performs a thorough post-concussion cognitive assessment that looks at:
✅ Attention span and working memory
✅ Mental endurance and processing speed
✅ Visual-cognitive tasks (like reading, tracking, scanning)
✅ Balance and vestibular stress on cognition
✅ Multitasking tolerance (dual-task testing)
✅ Environmental triggers like noise, motion, or screen time
Then, we build a personalized, evidence-based plan to gradually restore your brain efficiency and cognitive performance.
This might include:
Neurocognitive rehab drills (mental tasks paired with movement)
Eye movement and gaze stabilization training
Vestibular or balance rehab to reduce cognitive overload
Postural corrections to support visual-spatial orientation
Breathing or autonomic support to improve brain oxygenation and focus
When to Seek Help
If it’s been more than 2–3 weeks since your concussion and you’re still experiencing cognitive symptoms, it’s time to get evaluated. This isn’t “just in your head” — it’s your brain telling you something still needs support.
