Understanding Concussions: Causes, Symptoms, and Myths

Did you know that a simple bump to the head on a low cabinet door can cause a concussion? Or that most concussions don't involve losing consciousness at all? Misconceptions about brain injuries are everywhere, and they can prevent people from getting the care they need.

Concussions happen more easily than you think

Most people associate concussions with dramatic sports injuries or car accidents, but brain injuries can result from surprisingly minor incidents:

  • Everyday accidents like slipping on ice, tripping over a curb, or bumping your head on a low ceiling can cause concussions. Sudden stops in vehicles, low-speed fender benders, or bicycle accidents with helmets can also generate enough force to injure the brain.
  • Physical activities don't require high-impact contact to cause concussions. Cheerleading, horseback riding, water sports, certain dance moves, and vigorous exercise routines can cause rapid head movements that lead to brain injury.
  • Unexpected situations like playground accidents, amusement park rides, physical altercations, or rough play can cause concussions.

The key factor isn't the force of impact but the rapid acceleration and deceleration of the head that causes the brain to move within the skull.

Common misconceptions about concussions

Myth #1: You must lose consciousness to have a concussion.

Only about 10% of concussions involve loss of consciousness. Most people remain awake and alert throughout the injury.

Myth #2: No immediate symptoms means no concussion.

Symptoms can be delayed for hours or even days after the initial injury. Feeling fine immediately after an incident doesn't rule out a concussion.

Myth #3: Concussions are minor injuries you can "tough out."

Concussions are real brain injuries that require time to heal. Continuing certain strenuous activities without proper rest can lead to prolonged symptoms and complications.

Myth #4: Children recover faster than adults.

Children's developing brains may actually be more vulnerable to concussion effects and often require longer recovery periods. They may also struggle to articulate their symptoms clearly.

The wide range of concussion symptoms

Concussion symptoms extend far beyond headaches and can affect multiple body systems:

  • Cognitive symptoms include difficulty concentrating, memory problems, brain fog, and a general sense of mental slowness.
  • Physical symptoms may involve headaches, dizziness, vision problems, fatigue, nausea, and ringing in the ears.
  • Sensory changes often include sensitivity to light, noise, smell, and motion that wasn't present before the injury.
  • Sleep and mood effects can include insomnia, anxiety, depression, and irritability that develop after the concussion.
  • Autonomic and vestibular problems can cause balance issues, coordination difficulties, and impairments in the body's automatic functions.

If you have a history of migraine, mood disorders, or learning disabilities prior to the injury, those symptoms can get exacerbated after concussions.

Do you need to go to the ER?

Some symptoms immediately after a concussion a possible medical emergency. Get emergency care right away if you experience:

  • Loss of consciousness (even briefly)
  • Repeated vomiting or nausea
  • Worsening or severe headache
  • Slurred speech, confusion, or trouble recognizing people/places
  • Unequal pupils or vision changes
  • Seizures
  • Weakness, numbness, or trouble with balance/coordination
  • Unusual drowsiness or difficulty waking up
  • Clear fluid or blood draining from the nose or ears

When to see a neurologist

At any point after a concussion, it is never too early or too late to see a neurologist, especially if you’re experiencing symptoms. Book a visit with a neurologist:

  • Right away after any head impact, even if you haven't lost consciousness or don't see obvious signs of injury.
  • If you notice any symptoms, such as headache, dizziness, nausea, or confusion, even if they seem minor.
  • Within the first week, even if you feel fine, remember that symptoms can be delayed.
  • If symptoms hang around beyond 2-4 weeks when you expected to feel better.
  • Before resuming activities, ensure your brain has fully recovered.
  • When symptoms become chronic and start affecting your daily life.
  • If you've had previous concussions, you need specialized guidance on future risks.

Note: Concussion recovery can take time, especially with persistent post-concussive symptoms. A specialist can offer new insights into symptom management, explore advanced treatment options, and provide support for ongoing issues.
