Misconceptions About Concussion Care & Concussion Symptoms

The first sign is loss of consciousness

You do not have to lose consciousness or hit your head to have a concussion or symptoms of concussion. Any hit to your body that is strong enough to cause your head to forcefully jerk backwards, forwards, or to the side, puts you at risk for damage to the brain.

It's fine to wait a few weeks

before seeing a doctor. If a concussion is suspected, it's important to get medical evaluation within two days (or immediately if symptoms are severe) so a plan of care can be initiated. Up to 50% of people still have concussion symptoms such as headaches after 3 months, so follow-up is necessary, too.

Rest is the only treatment for concussion symptoms,

including mild concussion symptoms. In the first few days after a concussion, you may need to restrict activities, but then a gradual resumption of activities and an exercise program will speed recovery.

One evening, when Seth was biking home, a collision threw him off his bike and into the windshield of an oncoming car. Fortunately, he was wearing a helmet. But the windshield shattered, and blood gushed from his eyebrow. He wanted to continue on his way, but bystanders suggested otherwise.

An ambulance took him to a familiar place, the very medical center where he was in his second year of medical school. They scanned him for injuries, stitched up his face and shoulder, and sent him home.

The next day, he felt worse. For weeks and months, he had headaches, dizziness, episodes of blurry vision, sensitivity to light and sounds, and other difficulties.
