A sudden hit to the head, dizziness, or trouble focusing can be concerning. A concussion is a type of brain injury that can happen after a fall, accident, or blow to the head. Symptoms aren't always immediate, but the trauma in the brain can be developing, making it important to recognize key warning signs. This self-assessment quiz will guide you through key facts.

What Causes a Concussion?

A concussion happens when the brain moves rapidly inside the skull due to a blow or sudden jolt. This can happen during sports, car accidents, falls, or even minor bumps. While some concussions cause noticeable symptoms, others may not be obvious at first.

Can a Concussion Get Worse?

Most concussions heal over time, but ignoring symptoms or returning to normal activities too soon can make them worse. Some people experience lingering effects, such as headaches, dizziness, or memory problems, which can last for weeks or longer.

How Common Are Concussions?

Concussions are one of the most common brain injuries, affecting millions of people each year. Athletes, children, and older adults are at higher risk, but anyone can experience one. Many concussions go undiagnosed because symptoms can be subtle at first.

When Should You Be Concerned?

Feeling confused, having a headache, or experiencing nausea after a head injury could be a sign of a concussion. Symptoms may appear right away or develop hours later. Monitoring changes in thinking, balance, or mood can help determine if further attention is needed.
