Signs and Symptoms of a Concussion: What to Look for and First Aid Steps

A concussion is a common type of brain injury that can happen to anyone, from athletes on the field to children at play or adults involved in everyday accidents. Because symptoms may not always appear right away, it’s important to know the warning signs and how to respond. In this guide, we’ll explain the most common signs and symptoms of a concussion, when to call 9-1-1, and the essential first aid steps you can take until medical professionals arrive.

Concussions are common but serious. They can happen anywhere: on the field, in the car, at home. Recognizing the signs, acting quickly, and properly resting are essential to ensure safe recovery. When in doubt, always seek medical attention.

Understanding Concussions

A concussion is a form of traumatic brain injury that occurs when the brain is jolted inside the skull, often due to a direct blow to the head or sudden impact. While many people think a concussion always involves passing out, this isn’t true. A person may remain fully awake but still experience severe effects.

Symptoms can begin immediately, or they may not appear until hours or even days later. These can affect sleep patterns, mood, memory, concentration, and sensitivity to light and sound. Some people recover quickly, while others may experience lingering symptoms that last for days or longer.

Common Causes of Concussions

Concussions can happen in a wide variety of settings. Some of the most frequent causes include:

• Sports injuries (e.g., football, soccer, basketball, skateboarding)
• Falls (especially among older adults)
• Car accidents or bike accidents
• Physical altercations or assaults
• Any significant jolt to the head or body (including whiplash)

When to Call 9-1-1

All concussions should be taken seriously. If you suspect someone has sustained a concussion, call 9-1-1 or your local emergency number immediately.

Signs and Symptoms of a Concussion

Look for these warning signs after a head injury:

• Confusion that lasts from a few moments to several minutes
• Headache or pressure in the head
• Asking the same questions repeatedly
• Memory problems, especially about events just before or after the impact
• Brief loss of consciousness
• Nausea or vomiting
• Difficulty speaking or responding appropriately
• Blurry vision or sensitivity to bright light

First Aid Care Until Help Arrives

If you’re caring for someone with a suspected concussion, these are the first aid steps you should take:

• Keep the head and neck stable in the position you found them
• Make sure their airway is open and clear
• Manage any bleeding with dressings, but avoid applying direct pressure if a skull fracture is suspected
• If you notice clear fluid draining from the ears or scalp, cover the area loosely with a sterile dressing
• Stay with the person and watch closely for any changes in their condition
• Offer reassurance and keep them talking to help prevent loss of consciousness

Tips for Preventing Concussions

Prevention is always better than a cure. Here are ways to lower your risk:

• Use properly fitted helmets for biking, skateboarding, skiing, or contact sports
• Ensure protective equipment in sports is well-maintained and properly used
• Use seat belts in vehicles at all times
• Avoid impaired driving or riding with an impaired driver
• Improve home safety: secure rugs, install handrails, remove trip hazards
• Promote safe play spaces and supervision for children

Why First Aid Training Matters

Concussions can happen anywhere. Whether you’re on the sports field, at work, in a car accident, or even experience a simple fall, having knowledge and confidence to recognize the signs and symptoms of a concussion can make a significant difference in someone’s recovery.

How to Respond to a Suspected Concussion

If you suspect someone has a concussion, the most important step is to remove them from the activity that caused the injury and have them rest. Do not allow the person to return to sports, work, or any physical activity until they have been evaluated by a medical professional. Apply a cold pack to any visible swelling on the head, but never apply ice directly to the skin. Monitor the person closely for any changes in symptoms or behavior over the next 24 to 48 hours.

For children, concussion symptoms may be harder to recognize because young kids may not be able to articulate how they feel. Look for behavioral changes such as increased irritability, loss of interest in favorite activities, changes in sleep patterns, or regression in developmental milestones. Parents and child care providers should be especially vigilant about head injuries in children and seek medical evaluation promptly when concussion is suspected.

Concussion Prevention in Sports and Activities

Wearing appropriate protective equipment is the first line of defense against concussions during sports and recreational activities. Properly fitted helmets for cycling, skateboarding, skiing, and contact sports significantly reduce the risk of head injury. In California, youth sports organizations are required to follow concussion protocols that include removing athletes from play after a suspected head injury and requiring medical clearance before they return.

Workplace environments also present concussion risks, particularly in construction, manufacturing, and warehouse settings. OSHA mandates the use of hard hats and other protective equipment in hazardous work environments. Employers who provide first aid workshops for their teams ensure that staff can recognize concussion symptoms and respond appropriately, reducing the risk of complications from undiagnosed head injuries.

Long-Term Effects and When to Seek Help

Most concussions resolve within two to four weeks with proper rest and gradual return to activities. However, some individuals experience post-concussion syndrome, where symptoms persist for weeks or even months. Repeated concussions can have cumulative effects on brain health, making prevention and proper management crucial. Anyone who has experienced multiple concussions should work closely with a healthcare provider to develop a safe return-to-activity plan.

Understanding concussion management is an important component of comprehensive first aid training. Coast2Coast First Aid offers AHA-certified courses in Los Angeles, San Diego, Irvine, Riverside, and across California. We offer CPR/AED, BLS, group training, and more. Visit our blog or contact us.

Concussion Awareness in California Schools and Youth Sports

California Assembly Bill 2127 requires school districts to immediately remove any student athlete suspected of having a concussion from physical activity and prohibits them from returning until cleared by a licensed healthcare provider. This legislation reflects the growing understanding of concussion risks in youth sports and the importance of proper management. Coaches, teachers, and school nurses who complete first aid training are better equipped to implement these protocols and protect student athletes.

The CDC estimates that 1.6 to 3.8 million sports-related concussions occur in the United States each year, with many going unreported or undiagnosed. Educating young athletes, parents, and coaches about concussion symptoms and the importance of reporting head injuries creates a culture of safety that prioritizes long-term brain health over short-term competitive pressures. Schools throughout California from San Francisco to San Jose to Sacramento can benefit from our specialized training programs.

Recent research has also highlighted the importance of cognitive rest following a concussion, not just physical rest. This means limiting screen time, reading, studying, and other mentally demanding activities until symptoms improve. A gradual, step-by-step return to cognitive activities should be monitored by a healthcare provider, with each step lasting at least 24 hours before progressing. For students, this may mean modified school schedules and reduced homework loads during the recovery period. Understanding these recovery protocols is part of the comprehensive education provided in our first aid courses, preparing you to support concussion victims through their entire recovery journey. The knowledge you gain protects not just yourself but everyone around you, from family members to coworkers to fellow athletes.

Frequently Asked Questions

Question 1: What is a concussion?

Answer: A concussion is a form of traumatic brain injury caused by a bump, blow, or jolt to the head, or by a hit to the body that causes the head and brain to move rapidly back and forth, altering how the brain normally functions.
