Overview
A concussion is a type of traumatic brain injury that happens when your brain moves rapidly inside your skull. This movement can occur from a direct hit to the head or from a sudden jolt to your body that causes your head to snap back and forth. The rapid movement temporarily changes how your brain cells work.
Concussions affect people of all ages, from young children to older adults. They're especially common in contact sports like football, soccer, and hockey. About 3.8 million sports-related concussions occur in the United States each year. However, many concussions also happen from car accidents, falls, and other everyday incidents.
Understanding the signs and proper treatment of concussions is crucial for preventing long-term complications. While most people recover fully from a concussion, some may experience symptoms that last weeks or months. Getting the right care early can make a big difference in your recovery.
A concussion is sometimes called a "mild" brain injury, but that doesn't mean it's not serious. Even mild concussions need proper medical attention and care. Your brain is fragile, and any injury to it deserves respect and careful treatment. Taking your concussion seriously helps prevent future problems and speeds up your healing.
Symptoms & Signs
Concussion symptoms can vary greatly from person to person. Some people feel effects right away, while others don't notice problems until hours or days later. The symptoms can also change over time as your brain heals.
Primary Symptoms
Headache or pressure in the head - This is the most common symptom and can range from mild to severe
Confusion or feeling foggy - You might have trouble thinking clearly or remembering things
Dizziness or balance problems - You may feel unsteady on your feet or like the room is spinning
Nausea or vomiting - These symptoms often occur together and may worsen with movement
Sensitivity to light or noise - Bright lights or loud sounds might become very uncomfortable
Sleep changes - You might sleep more or less than usual, or have trouble falling asleep
Mood changes - Feeling irritable, sad, anxious, or more emotional than normal
Some people also experience problems with memory and concentration after a concussion. You might forget conversations or struggle to focus on schoolwork or your job. These cognitive problems usually improve with rest and time as your brain heals. If these symptoms persist for more than a few weeks, talk to your doctor about additional help.
When to Seek Care
You should get medical attention if you experience any concussion symptoms after a head injury. Even if symptoms seem mild at first, they can worsen over time. It's always better to be safe and have a doctor check you out after a suspected concussion. Can You Go to Urgent Care for a Concussion? provides helpful guidance on where to seek care.
When to Seek Immediate Care
Call 911 or go to the emergency room right away if someone has repeated vomiting, seizures, severe confusion, loss of consciousness, or worsening symptoms after a head injury.

Diagnosis
Medical History & Physical Examination
Your doctor will ask detailed questions about how your injury happened and what symptoms you're experiencing. They'll want to know about any previous head injuries and your medical history. The physical exam includes checking your balance, coordination, reflexes, and memory. Your doctor will also test your ability to concentrate and follow simple commands.
During the neurological exam, your doctor will check how your pupils respond to light and test your eye movements. They'll assess your strength, sensation, and reflexes throughout your body. This helps them understand how the injury has affected your brain function.
Diagnostic Testing
Cognitive testing - Computer-based tests that measure memory, attention, and thinking speed
Balance testing - Specialized equipment that measures how well you can maintain your balance
CT scan or MRI - Brain imaging that can rule out more serious injuries like bleeding or swelling
Neuropsychological testing - Detailed assessment of thinking abilities and emotional functioning
Treatment Options
The main goal of concussion treatment is to allow your brain to heal while managing symptoms. Most concussions get better with time and proper care.
Conservative Treatments
Physical and cognitive rest - Limiting activities that require concentration and avoiding physical exertion during the first few days
Gradual return to activities - Slowly increasing mental and physical activities as symptoms improve
Sleep management - Getting adequate sleep and maintaining regular sleep schedules to support brain healing
Stress reduction - Managing stress through relaxation techniques and avoiding overwhelming situations
Symptom management - Using appropriate medications for headaches while avoiding certain pain relievers that might increase bleeding risk
Rest is the most important part of treating a concussion. Your brain needs time and quiet to heal properly. During the first few days, avoid screens, homework, and challenging mental work. Let your brain rest just like you would rest a broken bone.
Advanced Treatments
Physical therapy - Specialized exercises to address balance problems and coordination issues when symptoms persist
Occupational therapy - Help with cognitive skills and strategies for returning to work or school activities
Vision therapy - Treatment for vision problems that can develop after a concussion
Specialized concussion clinics - Comprehensive care teams that provide coordinated treatment for complex cases
If your symptoms don't improve after one or two weeks, your doctor might recommend additional treatment options. These specialized therapies can help with lingering problems like balance issues or memory difficulties. Many people benefit greatly from working with specialists who focus on concussion recovery.
Living with the Condition
Daily Management Strategies
Start with complete rest for the first 24-48 hours after your injury. This means avoiding screens, reading, and strenuous mental activities. Gradually increase your activity level as your symptoms improve. Keep a symptom diary to track your progress and identify triggers that make symptoms worse. Stay hydrated and eat regular, nutritious meals to support your brain's healing process.
Returning to normal activities too quickly can slow your recovery. Be patient with yourself as you heal from a concussion. Some days will feel better than others, and that's normal. Celebrate small wins as you gradually get back to your regular routine.
Exercise & Movement
Begin with light walking when your doctor says it's safe. Avoid activities with risk of another head injury until you're fully recovered. Swimming, cycling, and contact sports should be avoided until cleared by your healthcare provider. Listen to your body and stop any activity that worsens your symptoms.
Talk to your coach or teacher about when you can return to sports or regular school activities. They can help you ease back into your normal schedule safely. Your healthcare provider will give you specific clearance before you return to contact sports or other risky activities.
Prevention
Wear proper protective equipment - Use well-fitted helmets during sports, cycling, and other high-risk activities
Follow safety rules - Learn and practice proper techniques in sports to reduce injury risk
Make your environment safer - Remove tripping hazards, use handrails, and ensure good lighting to prevent falls
Drive safely - Always wear seatbelts, avoid distracted driving, and never drive under the influence
Strengthen your body - Regular exercise improves balance, coordination, and bone strength, reducing fall risk
Prevention is always better than treatment when it comes to concussions. Make sure your helmet fits properly and is worn every time you're at risk of head injury. Teach young people the right way to play their sports and follow safety rules. Building a strong, healthy body with good balance helps protect you from falls and injuries.
Frequently Asked Questions
Most people recover from a concussion within 7-10 days. However, recovery time can vary from a few days to several months. Children and teens often take longer to heal than adults.
Yes, sleep is actually important for healing after a concussion. The old advice about staying awake was based on concerns about more serious brain injuries. Your doctor will tell you if you need to be monitored closely.
Acetaminophen is usually safe for concussion headaches. However, avoid aspirin and ibuprofen for the first 48 hours as they can increase bleeding risk. Always check with your doctor before taking any medications.
