What Is a Concussion?

A concussion is a mild form of brain injury that happens when your head gets hit, shaken, or jolted. This sudden movement can cause your brain to shift inside your skull, leading to short-term changes in how it works.

You don’t have to lose consciousness to have a concussion. Sometimes, symptoms appear right away; other times, they develop slowly over hours or even days. That’s why it’s important to pay attention to how you feel after any head injury.

A concussion can affect how you think, feel, and react. Most people recover with proper rest and care, but ignoring the signs can delay healing or make symptoms worse.

Concussions can happen to anyone, but they’re especially common among young people.

In the U.S., 7 out of 10 emergency visits for sports- and recreation-related concussions involve children aged 17 or under.

Common Concussion Symptoms

Symptoms of a concussion can vary from person to person. You might notice physical, mental, or emotional changes after the injury.

Common signs include:

• Headache or pressure in the head
• Dizziness or balance problems
• Blurred vision or sensitivity to light
• Nausea or vomiting
• Trouble concentrating or remembering things
• Feeling confused, slow, or “foggy”
• Unusual sleepiness, fatigue, or irritability

Sometimes, people also describe feeling “off” without being able to explain exactly why. That’s often one of the first signs that something isn’t right.

If you’re unsure, it’s always safer to get checked. A quick medical evaluation can prevent complications and help you recover faster.

How a Concussion Is Diagnosed and Treated

A concussion is usually diagnosed based on your symptoms and what happened during the injury. A healthcare professional will ask about the impact, how you felt afterward, and whether you’ve noticed changes in memory, balance, or mood. They might also check your coordination, vision, and ability to focus to see how your brain is responding.

Most concussions don’t require hospital tests like scans unless symptoms are severe. The main goal is to make sure there’s no bleeding or swelling in the brain.

Treatment focuses on rest and recovery. That means giving your brain time to heal by avoiding physical activity, bright screens, and stressful tasks for a few days. You can slowly return to normal routines once your symptoms improve. Listening to your body and taking things slowly helps prevent another injury and supports a full recovery.
