A concussion is a mild traumatic brain injury that temporarily disrupts brain function — it's a functional injury, not a structural one you can see on a scan. An estimated 1.7–3.8 million concussions occur in the US each year, with sports and recreation involved in roughly 1 in 10, and over 450,000 sports-related head injuries treated in emergency rooms annually. The encouraging news: most people feel significantly better within about two weeks with the right approach.

Common Symptoms

Physical

  • Headache, dizziness, or balance problems

  • Sensitivity to light or noise

  • Nausea or vision changes

Cognitive

  • Trouble concentrating

  • Feeling foggy, slowed down, or groggy

  • Memory difficulty

Emotional

  • Irritability or feeling more emotional

  • Anxiety or sadness

Sleep

  • Sleeping more or less than usual

  • Trouble falling asleep

Today's Treatment Approach

  1. Brief rest — about 24–48 hours of relative rest, not prolonged isolation.

  2. Sub-symptom aerobic exercise — light activity below the level that worsens symptoms, started early, meaningfully speeds recovery.

  3. Graduated return to school and activity — a stepwise progression, not all-or-nothing.

  4. Targeted rehab for lingering symptoms — vestibular, visual, and neck-based treatment when symptoms persist.

Why Visual & Vestibular Treatment Matters

A concussion can disrupt the reflex that keeps your eyes locked on a target while your head moves — so your balance system and visual system fall out of sync. That's why the room can feel like it's bouncing when you turn your head, or why reading and screens feel exhausting. This isn't rare: roughly 60% of athletes have vestibular or visual symptoms after a concussion, and left untreated, these are linked to a longer road back.

The evidence: in one study, athletes who received combined vestibular and neck-focused therapy returned to sport within 8 weeks at a rate of 73%, compared to just 7% of those who didn't. PT that targets the inner ear/balance system, eye-movement control, and the neck can meaningfully speed recovery — especially when symptoms linger beyond two weeks.

Risk Factors for Future Concussions

  • A prior concussion — each one raises vulnerability to another, especially before full recovery

  • Returning to play before you're fully recovered — the single biggest modifiable risk, and rarely, can trigger dangerous brain swelling (second impact syndrome)

  • Younger age — teenage brains often take longer to recover and may be more vulnerable to a repeat injury

  • High-contact sports and positions — football, hockey, rugby, and heading in soccer carry the highest exposure

Myths That Can Slow Recovery

Myth: You have to lose consciousness to have a concussion. Fact: Only 10–20% of concussions involve being “knocked out.”

Myth: A CT or MRI can diagnose a concussion. Fact: Concussions affect brain function, not visible structure — scans are usually normal.

Myth: Complete rest until all symptoms disappear speeds healing. Fact: Prolonged rest can delay recovery; gradual, guided activity works better.

Myth: Helmets prevent concussions. Fact: Helmets reduce fractures and severe injury, but haven't been shown to prevent concussions.

Myth: Kids bounce back faster than adults. Fact: Adolescents often need more recovery time and care than adults do.

Bottom line: Concussions are common, real, and treatable — but outdated advice like “just rest in a dark room” can slow healing. A guided, active recovery plan gets people back to school, work, and sport safer and sooner.
