Concussion research is constantly evolving, yet misinformation persists. Many patients come to us with outdated advice—like just resting until symptoms disappear—which can delay recovery. Here, we’ll debunk some common myths:

Concussions only result from head impacts.
- While a direct hit to the head is a common cause, any forceful acceleration or deceleration of the brain—such as a whiplash injury—can cause a concussion.
A concussion is a brain bruise.
- Unlike a cerebral contusion, a concussion results from stretching and shearing of brain axons, leading to functional, not structural, changes.
MRIs or CT scans can diagnose concussions.
- Concussions don’t show up on imaging because they affect brain function, not structure. Scans are only used to rule out other serious injuries like brain bleeds or skull fractures.
Rest is the best (or only) treatment.
- Prolonged rest can actually slow recovery. Instead, early “symptom-limited activity” (within 24-48 hours) is now recommended. A guided return to school/work and exercise is very important and can begin sooner than you’d think.
You’re fine to return to sports once symptoms subside.
- Symptom relief doesn’t mean full brain recovery. Returning too soon increases the risk of further damage. Objective testing is needed before resuming activity.
You must lose consciousness to have a concussion.
- Less than 10% of concussions involve loss of consciousness.
There’s no treatment for concussions.
- Targeted therapy—such as manual therapy, visual/vestibular rehab, guided exercise, and diet/nutrition—can significantly improve recovery.
Medication can treat concussions.
- Medications may help manage symptoms but don’t treat the concussion itself. Although they may be necessary in the early stages, some side effects can even mimic concussion symptoms.
Symptom increase means you're getting worse.
- Some symptom fluctuation is normal. Gradual exposure to stressors is key to recovery, especially during the PCS phase.
Helmets and mouth guards prevent concussions.
- They help reduce impact severity and may mitigate forces, but don’t stop the brain from moving inside the skull. Still, they’re crucial for preventing other serious injuries.
