Understanding Concussions: What You Need to Know

A concussion is a type of brain injury caused by a bump, blow, or jolt to the head. It can also happen when the head or body is shaken hard enough to make the brain move quickly back and forth inside the skull. This movement can damage brain cells and cause changes in how the brain works (CDC, 2022).

Concussions can happen to anyone — kids, adults, athletes, or people in everyday situations like car accidents or falls. Some common signs include confusion, dizziness, headache, nausea, blurry vision, or trouble remembering things. Sometimes, symptoms don’t appear right away and may show up hours or even days later (Mayo Clinic, 2023).

If you think someone has a concussion, it’s important they stop what they’re doing and see a doctor. Even if they feel okay, a medical check-up can prevent more serious problems. Rest is key. Most people recover fully, but returning to sports or normal activity too soon can make the injury worse or last longer (KidsHealth, 2022).

There is no quick fix for a concussion. Resting the brain — which means limiting screen time, loud music, and even reading in the first few days — helps the brain heal. Over time, light activity can be added as symptoms improve (Harvard Health, 2023).

The best way to deal with concussions is to try to prevent them. Wearing helmets during sports, using seatbelts in cars, and making living spaces safer can all help lower the risk.

If you or someone you know has had a head injury, don’t take it lightly. When it comes to the brain, it’s always better to be safe than sorry.
