A concussion is a type of injury to the brain that happens when you get a blow to the head. This can cause your brain to move around inside your skull. Even if the injury seems minor, it can still affect how your brain works for a while.
One of the things about concussion symptoms is that they might not show up right away. Some people might get a headache. Feel dizzy immediately, while others might not notice any symptoms for hours or even days.
It is really important to recognize the signs of a concussion and go see a doctor. This can help prevent complications and ensure you recover safely.
What Is a Concussion?
Medline Plus explains that a concussion is when your brain stops working because of a sudden impact or movement. Even though it is considered an injury, you should never ignore it.
How Does a Concussion Happen?
A concussion can occur in many everyday situations, including:
- Falls
- Sports injuries
- Motor vehicle accidents
- Workplace injuries
- Direct blows to the head
- Sudden whiplash-type movements
Children, older adults, athletes, and workers in physically demanding jobs may have a higher risk of sustaining a concussion.
What Happens Inside the Brain?
During a concussion, the brain shifts rapidly within the skull. This movement temporarily alters how brain cells function, leading to symptoms affecting thinking, balance, memory, and emotions.
Unlike severe brain injuries, most concussions do not show visible damage on routine CT scans or MRI scans. Because of this, healthcare providers rely primarily on a detailed medical history and neurological examination to diagnose a concussion.
What Are the Most Common Concussion Symptoms?
Concussion symptoms vary from person to person and may affect several aspects of brain function.
Physical Symptoms
Common physical symptoms include:
- Headache
- Dizziness
- Nausea
- Vomiting
- Balance problems
- Blurred vision
- Sensitivity to light
- Sensitivity to noise
- Fatigue
Headache is the most commonly reported symptom after a concussion.
Cognitive Symptoms
A concussion can affect thinking and memory, leading to:
- Confusion
- Difficulty concentrating
- Memory problems

These emotional symptoms often improve as the brain heals.

- Worsening headache

- Fatigue

Why Monitoring Is Important
Anyone with a suspected concussion should be closely observed during the first 24 to 48 hours after the injury. If possible, have a trusted adult accompany the injured person to monitor for worsening symptoms and seek emergency care if red-flag symptoms develop.
Concussion Symptoms in Children
The U.S. Centers for Disease Control and Prevention (CDC) explains that children may not always be able to describe how they feel, making careful observation especially important.
Infants and Toddlers
