How to Tell if Someone Has a Concussion

How to Tell if Someone Has a Concussion

Introduction to Concussions

A concussion is more than just a bump on the head—it’s a mild traumatic brain injury (TBI) that temporarily affects how the brain functions. Unlike cuts or bruises, you can’t always see a concussion from the outside, which is why it can be tricky to identify. Millions of people experience concussions every year, often without realizing how serious they can be.

So, how do you tell if someone has a concussion? The truth is, concussions come with a wide range of symptoms that can appear right away or develop slowly over time. Recognizing the signs early is essential because untreated concussions can lead to long-term health issues, including memory problems, mood disorders, and even chronic brain damage.

Think of your brain like a computer. When it gets shaken inside the skull, it’s like a sudden power surge—it might still run, but not as smoothly. That’s what happens in a concussion: the brain’s normal processes get disrupted. This disruption can affect how you think, feel, move, and even how your body reacts to light and sound.

In this article, we’ll break down the signs and symptoms of a concussion, what to watch for, when to seek medical help, and how recovery works. Whether it’s from a sports injury, a car accident, or even a simple fall, knowing how to spot a concussion can make all the difference.

Common Causes of Concussions

Concussions can happen to anyone, anywhere. While they’re often associated with athletes on the field, the truth is they can occur in everyday life situations. Let’s take a closer look at the most common causes:

Sports-Related Injuries

Athletes, particularly in contact sports like football, soccer, hockey, and boxing, are at high risk for concussions. Even a single blow to the head or body that causes the brain to jolt inside the skull can trigger one. Studies show that athletes who return to play too soon after a concussion are more likely to experience long-term brain issues.

Falls and Accidents

Falls are the leading cause of concussions, especially among children and older adults. A slip in the bathroom, tripping on stairs, or even a minor tumble can cause enough impact to injure the brain. In older adults, weaker bones and slower reflexes make them especially vulnerable.

Car Crashes and Other Traumatic Events

Vehicle collisions often result in concussions due to the sudden force that whips the head forward and back. Even if the person doesn’t hit their head on the steering wheel or window, the sheer motion can cause brain trauma. Other traumatic events, like workplace accidents or fights, can also be culprits.

It’s important to note that you don’t always need a direct hit to the skull to get a concussion. A hard blow to the body that causes the head to jerk can be enough to rattle the brain.

Immediate Signs and Symptoms of a Concussion

Spotting a concussion early is crucial. While symptoms vary from person to person, there are some common red flags to look out for right after an injury.

Physical Symptoms

The first signs are often physical. The person might complain of:

• A persistent headache or pressure in the head

• Dizziness or feeling unsteady

• Blurred or double vision

• Nausea or vomiting

• Ringing in the ears

These symptoms can range from mild discomfort to severe impairment, but even if they seem minor, they should never be ignored.

Cognitive Symptoms

A concussion can temporarily scramble the brain’s ability to think clearly. Watch for signs like:

• Confusion about time, place, or events

• Difficulty remembering what happened before or after the injury

• Slow responses to questions

• Trouble concentrating

It’s almost like the brain is buffering, struggling to process information as quickly as it normally does.

Emotional and Behavioral Symptoms

Not all symptoms are physical. Some people may become unusually irritable, sad, or anxious shortly after a concussion. Others may seem dazed, distant, or “not themselves.” These mood shifts can be subtle but are just as important to recognize.

---

Delayed Symptoms of a Concussion

Here’s the tricky part: not all concussion symptoms show up immediately. Some develop hours or even days later, making it harder to link them to the injury.

Symptoms That Appear Hours or Days Later

It’s not uncommon for someone to feel “fine” right after a fall or collision, only to develop issues later. These delayed symptoms can include:

• Worsening headaches

• Blurry vision

• Dizziness that comes and goes

• Sensitivity to light or noise

Sleep Disturbances and Fatigue

Concussions can disrupt normal sleep patterns. A person may feel unusually tired, sleep longer than usual, or struggle with insomnia. This change in sleep is one of the clearest indicators that the brain is still recovering.

Difficulty Concentrating and Mood Swings

School, work, or even everyday conversations can suddenly feel overwhelming. Many people report difficulty focusing, “zoning out,” or feeling mentally drained. Mood swings—going from calm to angry or sad in minutes—are also common.

These delayed symptoms make it critical to monitor someone closely for at least 24–48 hours after a head injury. Just because they seem okay at first doesn’t mean they’re out of danger.

---

Physical Indicators to Watch For

Sometimes, the body gives away signs that the brain is struggling, even before the person realizes it.

Loss of Consciousness (Even Briefly)

Not everyone with a concussion passes out, but if someone does—even for a few seconds—it’s a strong indicator of brain trauma. Loss of consciousness means the brain’s normal activity was disrupted.

Unsteady Balance and Coordination Issues

If someone seems clumsy, sways when walking, or struggles to keep their balance after a hit, it could be a red flag. The brain controls movement and coordination, and any disruption can show up in how a person walks or stands.

Sensitivity to Light and Noise

Another physical sign is increased sensitivity to bright lights or loud sounds. The brain becomes hypersensitive after trauma, making normal environments feel overwhelming.

These physical indicators are important because they can help you identify a concussion even if the person downplays their symptoms.

---

While physical symptoms might be the most obvious, concussions often interfere with how a person thinks, remembers, and processes information. These mental changes can be subtle at first but tend to become more noticeable as the brain struggles to function normally.

Trouble Remembering the Event

One of the clearest indicators of a concussion is memory loss surrounding the injury. The person may not recall what happened immediately before the accident (retrograde amnesia) or what occurred afterward (anterograde amnesia). For example, an athlete who was injured during a game might remember warming up but not recall how they ended up on the ground.

This memory gap can be short-lived or last for hours. Even if the person regains their memory later, the initial confusion is a sign of brain trauma. It’s important not to dismiss this symptom as “just being shaken up.”

Slurred Speech and Slow Responses

After a concussion, people may have trouble articulating their thoughts clearly. They might slur their words, speak unusually slowly, or take longer to respond to questions. Imagine trying to talk while half-asleep—that sluggishness is what it often looks like.

If someone’s speech seems off or delayed, it’s a warning that their brain isn’t processing language and communication normally.

Difficulty Focusing or Processing Information

A concussion can feel like having a mental fog. The person might:

• Struggle to follow conversations

• Lose track of what they were saying

• Have difficulty reading or solving simple problems

• Appear easily distracted

This inability to think clearly is frustrating for the individual and noticeable to others. Teachers often spot these signs in students after a sports injury, as schoolwork suddenly becomes much harder to manage.

---

Emotional and Behavioral Changes After a Concussion

A concussion doesn’t just affect the brain’s physical and cognitive functions—it also disrupts emotions and behavior. These changes can be surprising for friends and family, especially if the injured person starts acting very differently than usual.

Irritability and Frustration

Small inconveniences can trigger big reactions after a concussion. Someone who is normally calm may become short-tempered, snapping at people over minor issues. This irritability often comes from the frustration of not being able to think or perform as they normally would.

Anxiety and Depression Symptoms

It’s common for concussion patients to feel anxious or depressed during recovery. Part of this comes from chemical changes in the brain, while another part is the stress of dealing with symptoms like memory problems, headaches, and fatigue. These mood changes should be taken seriously, especially if they persist.

Personality Changes

Perhaps the most concerning behavioral symptom is a noticeable shift in personality. A normally outgoing person may become withdrawn and quiet, or someone usually cheerful might seem constantly sad or angry. Family members often notice these changes before the injured person does, making it important to pay close attention.

When to Seek Emergency Help

Not every concussion requires an emergency room visit, but certain symptoms are considered red flags and need immediate medical attention.

Danger Signs That Require Urgent Care

Call emergency services or go to the hospital if the person:

• Loses consciousness for more than a few seconds

• Has repeated vomiting

• Experiences worsening headaches

• Has seizures

• Shows weakness or numbness in arms or legs

These signs suggest that the concussion may be more severe or accompanied by a brain bleed, which can be life-threatening.

Red-Flag Symptoms That Cannot Be Ignored

Other warning signs include:

• One pupil larger than the other

• Clear fluid or blood draining from the nose or ears

• Difficulty waking up or staying awake

• Slurred or incoherent speech

• Increasing confusion or agitation

If any of these occur, don’t wait to “see if it gets better.” Immediate medical evaluation is crucial to rule out serious complications like intracranial bleeding.

Diagnosis of a Concussion

Determining whether someone has a concussion isn’t always straightforward. Doctors rely on a combination of medical history, physical exams, and sometimes imaging tests to make a proper diagnosis.

Medical Evaluation and Imaging Tests

When a concussion is suspected, doctors first ask about the injury and symptoms. While concussions don’t usually show up on CT scans or MRIs, these imaging tests may still be ordered to rule out more serious issues like skull fractures or brain bleeds.

Neurological Examination

Doctors check reflexes, balance, coordination, and eye movements to see how the brain is functioning. Simple tasks like following a finger with the eyes or walking in a straight line can reveal subtle signs of brain injury.

Cognitive and Memory Assessments

Patients may also be asked to recall words, solve simple problems, or repeat numbers. These tests measure how well the brain is processing and retaining information. In sports, specialized concussion tests (like the SCAT5) are often used on the sidelines to quickly evaluate athletes.

A proper diagnosis is key to ensuring safe recovery. Without medical evaluation, it’s easy to underestimate the severity of the injury.

---

Recovering from a concussion isn’t a one-size-fits-all process. Each person heals at a different pace depending on the severity of the injury, their overall health, and how well they follow medical advice. While many concussions resolve within a few weeks, some can take months. The key to recovery is patience and proper care.

Rest and Activity Modification

The first step after a concussion is rest—both physical and mental. Doctors often recommend taking a break from strenuous activities like sports, exercise, or heavy lifting. But it’s not just about physical rest; mental rest is equally important. This means limiting screen time, reading, and even school or work tasks that require concentration.

Think of it like giving your brain a “vacation” to heal. Pushing through symptoms or rushing back to normal routines can make recovery longer and more complicated.

Medical Follow-Up and Monitoring

Concussions require follow-up appointments to track progress. Doctors may ask about headaches, sleep patterns, mood changes, and memory issues. If symptoms persist, additional tests may be needed.

Some patients benefit from physical therapy, especially if balance and coordination are affected. Others might need counseling or medication for mood-related symptoms. The goal is to monitor recovery closely and adjust treatment as needed.

Returning to School, Work, or Sports Safely

One of the most common mistakes people make is going back to normal life too soon. For athletes, this can mean returning to the field while the brain is still vulnerable, risking another concussion. For students, diving into schoolwork too quickly can worsen symptoms.

Doctors usually recommend a gradual return:

1. Rest until symptoms improve.

2. Resume light activities (like short walks or easy reading).

3. Slowly increase workload or training intensity.

4. Only return to full participation once completely symptom-free and cleared by a doctor.

Risks of Ignoring a Concussion

Downplaying a concussion or ignoring symptoms can have serious consequences. What might seem like a minor head injury can actually lead to long-term problems if left untreated.

Post-Concussion Syndrome

Some people experience symptoms for weeks or even months after the initial injury. This condition, called post-concussion syndrome, includes persistent headaches, dizziness, memory problems, and mood changes. Daily life can feel overwhelming, making work, school, and relationships difficult.

Second Impact Syndrome

This rare but life-threatening condition occurs if a person suffers another concussion before fully recovering from the first one. The brain swells rapidly, often with catastrophic results. Athletes who return to sports too soon are especially at risk, which is why strict medical clearance is essential.

Long-Term Cognitive Impairments

Repeated concussions or untreated brain injuries can lead to long-term issues such as:

• Memory loss

• Difficulty concentrating

• Chronic headaches

• Increased risk of depression and anxiety

In severe cases, multiple concussions have been linked to degenerative brain diseases like chronic traumatic encephalopathy (CTE), which has been found in professional athletes.

Ignoring a concussion is like ignoring a car engine warning light—you might keep driving for a while, but the damage is happening underneath.

Preventing Concussions

The best way to deal with concussions is to prevent them in the first place. While not every accident can be avoided, certain steps reduce the risk.

Safety Gear and Helmets

Helmets are essential in sports like football, hockey, cycling, and skateboarding. While they don’t guarantee total protection, they significantly reduce the risk of severe head injuries. The same goes for seat belts in cars—they don’t prevent all injuries, but they save lives.

Safe Practices in Sports and Daily Life

Athletes should be trained in safe playing techniques and encouraged to speak up about symptoms instead of hiding them. At home, keeping floors clutter-free, using non-slip mats, and installing handrails can prevent falls, especially for children and older adults.

Awareness and Education

Perhaps the most powerful tool is awareness. Parents, coaches, teachers, and even friends should learn to recognize the signs of concussion. Early detection and care can prevent minor injuries from becoming major health problems.

---

Concussions in Children vs. Adults

Concussions don’t affect everyone the same way. Children and adults experience and recover from concussions differently, making it important to understand the differences.

Differences in Symptoms

Children may not be able to explain their symptoms clearly. Instead of saying they feel dizzy or confused, they might simply seem cranky, unusually tired, or uninterested in playing. Adults, on the other hand, can describe headaches, memory issues, or difficulty concentrating.

How Recovery Differs Between Age Groups

Kids often take longer to recover because their brains are still developing. This means extra caution is needed before they return to school or sports. Adults usually recover faster, but older adults may face complications due to age-related health issues.

Special Care Considerations

Parents and caregivers should monitor children closely for changes in sleep, appetite, or behavior after a head injury. Teachers should also be informed, as schoolwork may need temporary adjustments. For adults, especially those in high-risk jobs or sports, medical clearance is critical before resuming normal activities.

---

Despite increased awareness, many misconceptions about concussions still circulate. Believing these myths can delay proper treatment or put someone at risk of further injury. Let’s clear up some of the most common ones.

Common False Beliefs

One widespread myth is that you must lose consciousness to have a concussion. In reality, most concussions happen without any loss of consciousness. Another myth is that concussions only occur from direct blows to the head. As we’ve discussed, a hard impact to the body that jolts the head can be enough to cause one.

Some people also believe concussions aren’t serious and that you can simply “shake it off.” This dangerous mindset often leads athletes back into play too soon, putting them at risk of long-term brain damage.

Scientific Facts vs. Myths

• Myth: You can always tell if someone has a concussion right away.
  Fact: Symptoms may appear hours or days later.

• Myth: Helmets prevent concussions completely.
  Fact: Helmets reduce the risk of severe head injuries but can’t eliminate concussions entirely.

• Myth: You shouldn’t let someone with a concussion sleep.
  Fact: Sleep is an important part of recovery. What matters is monitoring the person for worsening symptoms.

Why These Misconceptions Are Dangerous

These false beliefs minimize the seriousness of brain injuries and lead to delayed medical care. By spreading correct information, we can encourage people to take concussions seriously, seek medical attention promptly, and follow safe recovery guidelines.

---

Conclusion

Concussions are more than just a minor bump to the head—they are brain injuries that can have lasting consequences if ignored. Knowing how to recognize the signs and symptoms, from headaches and dizziness to memory loss and mood changes, is crucial for early intervention.

Whether the injury happens on a sports field, in a car accident, or during a simple fall at home, quick action and proper care can make all the difference. Rest, medical evaluation, and a gradual return to normal activities are key to recovery.

Most importantly, we must move past the myths and misconceptions that downplay concussions. Every suspected concussion deserves attention, because the brain is too important to risk. By staying aware, educating others, and prioritizing safety, we can reduce the dangers of concussions and protect long-term brain health.
