Almost everyone has hit their head and seen stars. Sometimes it kind of dazes us. We usually rub it and go on with what we’re doing. But sometimes, people get symptoms, and they linger. Then the question becomes, do you have a concussion? And why does it matter to know?
I hope you know you should see a doctor if you ever get knocked out. But what if you just have bad headache? And what should you do if you can’t get to a doctor?
We’re learning more and more how seemingly minor concussions can damage our thinking for as much as a lifetime. No matter the reason for the head trauma, whether it’s sports or a fall or a tree limb, you should know what to watch for and what you should do.
Any sport has its share of concussions—any—from soccer to football to basketball to cheerleading. Concussion can happen at all ages, but a mild concussion in a young person’s still-developing brain has the potential to be more serious than in an adult’s.
Still, that doesn’t mean we older folks shouldn’t worry. For instance, the military has gone into overdrive trying to learn how to prevent concussions and what the best treatment is to diminish long-term effects. And if you follow pro football, you know concussions have become the sport’s most talked-about injury. Many former players are just now reaping the damage from the times they “got their bell rung” and just shook it off. Multiple concussions take their toll.
But, even after one concussion—even what we’d call a mild one—the effects can linger for weeks to months to years, especially if the injury isn’t treated correctly.
Do You Have a Concussion?
Check the Neck
Never forget, if there is a head injury, there could be a serious neck injury. Check the neck thoroughly. Neck injuries cannot ever be ruled out unless the person is alert enough to follow commands and tell you what hurts, what’s numb, etc. See my post and video for stabilizing a neck.
In order to know if you have a concussion, technically termed a “mild traumatic brain injury,” you have to know the signs and symptoms to look for. Most of the following information comes from the CDC’s website section on concussions. The “Heads Up” videos are especially good.
Get to a Doctor
Of course, a thorough, expert medical exam and X-rays—if indicated—are essential after any head or neck trauma, but it becomes a must even if it’s hard to get to a doctor if there is:
- Any loss of consciousness greater than 30 seconds
- Weakness or numbness of an arm or leg, hand or foot, fingers or toes
- Neck tenderness
- Loss of range of motion in the neck
Signs and symptoms of a concussion come in four general categories. These problems can occur immediately or start hours after the injury.
- Increased sensitivity to light or sounds
- Trouble with balance
- Nausea or vomiting
- Double or blurry vision
Quick exams to check for these signs and symptoms:
- Have the person stand, feet together and eyes closed. Be ready to catch if they start falling because of balance problems. If they pass this …
- Have them open their eyes and stand on one foot.
- Have them walk a straight line.
- Have them stretch out a hand, then touch their nose with their index finger. Alternate hands and repeat a few times.
If the person has problems with any of these, think concussion.
- Amnesia (can be trouble remembering things that happen either before or after the injury)
- Loss of consciousness
- Feeling foggy
- Disorientation—trouble knowing what happened, where they are, who they are, or what day it is.
- Trouble focusing
- Slurred speech
- Slowed verbal or physical responses
- Excessive drowsiness
- Ask them their name, your name, what day it is, and where they are. If they can’t answer all the questions, or if they answer very slowly, they’ve likely had a concussion.
- Place your pointer finger about a foot from their face. Have them follow your finger as you move it from side to side, up and down, and diagonally. They should be able to follow it without much lag time.
- Mood swings
- Increased irritablility
- Excessive fatigue that lingers
- Trouble getting to sleep
- Sleeping more than usual
- Sleeping less than usual

When a Concussion Becomes an Emergency
The CDC has a chart you can download to follow the status of someone post-concussion. Click here to download the PDF.
Any person with a concussion should be observed for 24–48 hours for any new problems and for initial problems getting worse. If things do get worse, it becomes essential that the person get expert medical help right away since they are going to need further evaluation, along with treatment that just can’t be done in the field.
Danger signs and symptoms include:
- Increasing headache
- Slurred speech
- Repeated vomiting
- Increasing confusion
- Increasing irritability
Exam: Shine a light in one eye, then the other, to check the pupils. They should react and constrict equally. Note the initial exam, repeat every 30 minutes for a couple of hours, then every two hours for the next 24. Watch for changes. It’s much better to do this in a fairly dark place so the eyes will be dilated to start. Try it on a friend to get the hang of it, so you know what a normal exam looks like.
Aha! You Have a Concussion. What to Do.
Other than the above,
1. Rest. It is essential. Any person with a concussion needs to rest physically and mentally until the symptoms have been gone for 24 hours. That means no play and no school. And if you’re in a disaster, someone else needs to take charge if at all possible. It’s not only the danger of poor judgment that makes this important. It’s not even just the fact that getting a second concussion before the first heals is particularly dangerous. It’s that a concussion affects your whole brain. The metabolism changes, the synapses fire improperly. Physical activity can worsen this and also prolong recovery. So can mental activity. You have to rest your thinking. No texting or videogames, no television or reading, and delegate all decision making you can.
The symptoms can last from a few hours to many months. After they’ve gone away for 24 hours …
2. Gradually start back the mental and physical activities. If the headache or other symptoms return, you need to do less activity for 24 more hours.
I know this can be very, very inconvenient. But if you don’t do it right, symptoms will linger. In fact you may never get back to normal.
However, the good news is the vast majority of people with concussions do return to normal brain function, usually within 24–48 hours, especially if it’s their first concussion.
What about you? Have you known anyone who had a concussion? How did they do?
