Sustaining a blow to the head can be alarming, and it's important to recognize whether it has resulted in a concussion. A concussion is a mild traumatic brain injury (TBI) that temporarily affects brain function. It often occurs due to a sudden impact to the head or body, causing the brain to move rapidly within the skull (1).

Many people assume that a concussion only happens if they lose consciousness, but this isn’t always the case. Symptoms of a concussion can appear immediately or develop over hours or even days. Identifying the signs of a concussion early and seeking medical care can significantly impact recovery (2).

Quick Takeaways

• A concussion is a type of mild traumatic brain injury (TBI).

• Concussion symptoms include headache, dizziness, confusion, nausea, and memory issues.

• Loss of consciousness is not required for a concussion to occur.

• Symptoms can develop immediately or take time to appear.

• Medical evaluation is crucial to prevent complications.

• Rest and gradual return to activity are key for recovery.

• Seeking expert care ensures proper diagnosis and treatment.

Understanding Concussions

A concussion occurs when a sudden jolt or blow causes the brain to move inside the skull. This movement can stretch and damage brain cells, leading to temporary changes in brain function (1). While concussions are often associated with sports injuries, they can also result from falls, car accidents, or any impact to the head (2).

The severity of a concussion varies from person to person. Some individuals recover within a few days, while others may experience lingering symptoms for weeks or even months. Understanding the warning signs of a concussion can help you determine when to seek medical attention (3).

Common Symptoms of a Concussion

Concussion symptoms can be grouped into four main categories:

Cognitive Symptoms

• Difficulty concentrating or remembering recent events

• Feeling mentally "foggy" or slow

• Confusion about surroundings

Physical Symptoms

• Headache or pressure in the head

• Nausea or vomiting

• Dizziness or balance issues

• Sensitivity to light or noise

Emotional Symptoms

• Irritability or mood swings

• Anxiety or nervousness

• Increased emotional sensitivity

Sleep-Related Symptoms

• Sleeping more or less than usual

• Difficulty falling or staying asleep

Symptoms can appear right away or gradually over time. If you notice any of these signs a concussion may be present, it’s important to stop activity and seek medical evaluation (4).

What to Do If You Have a Concussion

If you think you or someone else has a concussion, follow these steps:

1. Stop All Activity Avoid physical exertion and any activities requiring focus, such as reading, screen time, or driving. Rest is essential for recovery.

2. Seek Medical Evaluation A healthcare provider can assess symptoms, perform cognitive tests, and determine the severity of the concussion. They may recommend rest, observation, or further imaging tests if needed.

3. Follow a Rest and Recovery Plan Resting both physically and mentally is key. Avoid strenuous activities and limit screen time until symptoms improve. Some individuals may require a gradual return to school, work, or sports.

4. Gradually Return to Normal Activities Once symptoms begin to subside, a doctor may suggest slowly reintroducing activities. Rushing recovery can prolong symptoms or lead to complications (4).

Conclusion

Recognizing the signs of a concussion and taking the proper steps for recovery can prevent long-term complications. If you suspect a concussion, seek medical attention immediately. Early diagnosis and proper care can make a significant difference in recovery.

For specialized care, consider scheduling an evaluation with the concussion specialists at Midwest Orthopaedics at Rush to ensure your recovery is on the right track.

FAQs

Q: Can you have a concussion without hitting your head?

Yes. A concussion can occur from any sudden jolt or impact that causes the brain to move within the skull, such as a whiplash injury.

Q: How long does a concussion last? 

Recovery varies, but most mild concussions improve within 7-14 days. Some cases take longer, especially if symptoms are not managed properly.

Q: Should I sleep after a concussion? 

Yes, rest is crucial. However, if symptoms worsen after sleeping, seek medical attention immediately.

Q: What should I do if symptoms get worse? 

If headaches, dizziness, or confusion worsen, visit a doctor immediately. These could be signs of head injury or a more serious brain injury.

Q: Are children more vulnerable to concussions? 

Yes. Children and teens take longer to recover from concussions and should be closely monitored after a head injury.
