How to Tell If a Person Has a Concussion

Checking for Immediate Signs

Determine if the victim has lost consciousness. Not everyone who gets a concussion will lose consciousness, but some people do. This is the most obvious sign that someone has a concussion. If the person has blacked out after a blow to the head, seek emergency medical treatment.

Watch for slurred or unclear speech. Ask the person some basic questions such as, “What is your name?” and “Do you know where you are?” If their answers are delayed, slurred, don’t make sense, or are hard to understand, they may have a concussion.

Find out if the victim is confused or doesn’t remember what happened. If the person has a blank stare, seems confused, or doesn’t know where they are, it could be a sign of a brain injury. If they seem dazed, don’t remember what happened, or appear to have memory loss, they likely have a concussion.

Watch for nausea or vomiting. If someone vomits, especially repeatedly, after being hit in the head or involved in another type of accident, this usually indicates a concussion. If they haven’t vomited, ask them if they feel nauseated or have an upset stomach, which may also be a sign of a concussion.

Look for impaired balance or coordination. People with concussions often have problems with their motor skills, such as being unable to walk in a straight line or catch a ball. If the person is having trouble with these things or has a delayed reaction time, they likely have a concussion.

Ask the victim if they have a headache, blurred vision, or feel dizzy. A headache that lasts more than a few minutes is a common sign of a concussion. Blurred vision, “seeing stars,” and/or feelings of dizziness or fogginess may also indicate a concussion.

Watch the person carefully for 3-4 hours. If you suspect a concussion, the person should be carefully monitored for the next several hours. Symptoms of a concussion often change over a period of time. It’s not a good idea to leave them alone, in case they end up needing emergency medical treatment. If possible, arrange for someone to stay with the person for at least a few hours after the incident and monitor their behavior.

Monitoring Them for Additional Symptoms

Look for symptoms over the next several days or weeks. While some concussion symptoms show up immediately, some don’t appear until days or weeks afterwards. Even if the person seemed fine after the incident, they may begin to show signs of a concussion later on. The victim may exhibit signs such as slurred speech, confusion, nausea or vomiting, impaired balance or coordination, dizziness, blurred vision, or headache. These symptoms could indicate medical issues other than a concussion, so it’s important to have the person examined by a healthcare provider.

Watch for changes in mood and behavior over the next month. Sudden changes in behavior or mood often indicate a concussion. If the person seems grouchy, irritable, angry, sad, or otherwise emotional, seemingly without a reason, they may have a concussion. If the person becomes violent, acts out, or loses interest in their favorite things or activities, this can also indicate a concussion.

Determine if they have sensitivity to light or sound. People that are suffering from concussions are often more sensitive to bright lights and loud noises. If these things make the person cringe or complain of pain, or if they have ringing in their ears, they may have a concussion.

Recognize changes in eating or sleeping patterns. Look for behavior that contradicts their usual patterns or habits. If the person has lost their appetite or is eating much more than normal, it could be a sign of a concussion. Similarly, if the person has trouble sleeping or is sleeping excessively, they may have a concussion.

Find out if the victim has problems with memory or concentration. Even if the person seems clear-headed after the incident, they may develop issues later on. If they seem unfocused, unable to concentrate, or have trouble remembering things that happened either before or after the incident, they likely have a concussion.

Watch for excessive crying in children. If the person that you suspect may have a concussion is a child, determine if they seem to be crying more than usual. Though most of the concussion symptoms are the same in children and adults, children may cry excessively because they are in pain, feeling off, or don’t know how to express what is wrong.

Seeking Medical Treatment

Seek emergency medical care for seizures, difficulty breathing, or fluid leaking from the ears. If the victim doesn’t respond or wake up after losing consciousness, experiences worsening headaches, vomits repeatedly, has blood or fluid leaking from the ears and nose, has a seizure, difficulty breathing, or slurred speech, take them to the emergency room immediately. These symptoms could indicate a very serious brain injury.

Get a medical evaluation for anyone with a suspected concussion within 1-2 days. Even if emergency medical treatment isn’t required, all head injuries should be evaluated by a licensed healthcare professional. If you suspect someone has a concussion, take them to the doctor within 2 days of the incident.

Get immediate medical attention if the victim’s symptoms worsen. In general, the symptoms of a concussion decrease over time. If the opposite is happening and the person experiences worsening pain, such as headache, and/or increased fatigue, seek immediate medical attention. These signs could indicate a more serious injury.

Follow the prescribed treatment plan. Usually, bed rest is prescribed for people with concussions. This includes both physical and mental rest, meaning the person should avoid physical activity (like exercise) as well as strenuous mental activity (such as playing video games or doing crossword puzzles). Be sure to rest for as long as the doctor recommends, and always follow any other treatment plan as prescribed by your healthcare provider.

Avoid exercise and activity until cleared by a doctor. If the victim got a concussion while playing a sport, exercising, or doing another physical activity, remove the person from the game or activity. They should not resume the activity until evaluated by a doctor, especially if it is a contact sport in which they may get hit again.
