A concussion is a temporary brain injury that can affect anyone who experiences a significant blow, bump, or jolt to the head or body. While the skull provides a hard protective casing for the brain, a sudden impact can cause the brain to move back and forth rapidly, leading to chemical changes and temporary disturbances in normal brain function. It is a common misconception that concussions only happen to athletes. In reality, these injuries occur across all age groups and in various everyday settings, from the home to the workplace.

Understanding who is at risk of a concussion
Anyone can get a concussion if they sustain a blow to the head or a violent shaking of the head and upper body. While no one is immune, statistics show that certain populations are more frequently affected due to their physical activities, environments, or biological factors. These groups often require more specific preventative measures and careful monitoring following an incident.
The risk is not solely determined by the force of the impact but also by how the brain reacts to the sudden movement within the skull. Factors such as neck strength, previous history of head injuries, and overall physical health play significant roles in how a person might be affected. Recognising who is most vulnerable is the first step in ensuring appropriate care and intervention.
Why children and adolescents are highly vulnerable
Children and teenagers are among the most common groups to experience concussions because their brains are still developing and their skulls are thinner than those of adults. Young people often engage in high-energy play and sports where collisions are more likely. Furthermore, their neck muscles are typically weaker, which means their heads may move more violently upon impact, increasing the “shaking” effect on the brain.
In children and young people, the symptoms of a concussion may be more difficult to spot and can sometimes take longer to resolve compared to adults. Because a child’s brain is in a critical stage of growth, sustaining a concussion can sometimes interfere with school performance and emotional regulation. Parents and coaches are encouraged to be particularly vigilant during sports and play, ensuring that any child who hits their head is removed from activity immediately.
The increased risk of falls in older adults
Older adults, particularly those over the age of 65, represent another high-risk group for concussions, primarily due to an increased frequency of falls. Age-related changes in balance, vision, and muscle strength can make trips and slips more likely in the home environment. Additionally, many older individuals may be taking medications, such as blood thinners, which can complicate the outcome of a head injury.
The following table compares the primary risks for different age groups:
| Age Group | Primary Cause of Concussion | Key Risk Factor |
| Infants and Toddlers | Falls from furniture or stairs | Developing motor skills and large head-to-body ratio |
| Children and Teens | Sports, play, and cycling | Still-developing brain and high activity levels |
| Young Adults | Road traffic accidents and assaults | Higher exposure to high-velocity environments |
| Older Adults | Slips and falls in the home | Reduced balance, mobility issues, and medication |
Individuals in high-risk occupations and sports
People who work in certain industries or participate in contact sports face a daily increased risk of head trauma. Occupational settings like construction sites, warehouses, and emergency services often involve physical hazards, such as falling objects or the risk of falling from heights. Even with strict health and safety protocols and the use of hard hats, the risk of a jolt to the brain remains present.
In the sporting world, athletes involved in rugby, football, boxing, and horse riding are frequently exposed to impacts. It is important to note that a concussion does not always require a direct hit to the head. A blow to the chest or a heavy fall onto the back can cause the head to snap back or forward with enough force to injure the brain. UK sporting bodies have established clear return-to-play guidelines to ensure that no athlete returns to the field until their brain has fully recovered.
Medical factors and previous injury history
Certain medical conditions and histories can make a person more susceptible to sustaining a concussion or experiencing more severe symptoms. For instance, individuals who have had a concussion in the past are statistically more likely to sustain another one. This is partly because the brain may be more sensitive to impact during the recovery phase, and partly because the circumstances that led to the first injury might still be present.
People with pre-existing neurological conditions or those who suffer from frequent dizzy spells or balance disorders are also at higher risk. These conditions can make a person less steady on their feet, increasing the probability of a fall. It is essential for individuals with these health concerns to take extra precautions in their daily lives, such as ensuring their home environment is free of trip hazards and wearing appropriate footwear.
Conclusion
Concussions are not limited to any single group but can affect anyone from young children to older adults. While sports and accidents are common triggers, everyday falls remain a leading cause of head injuries across the UK. Understanding your personal risk factors and those of your family members is vital for prevention and early recognition of symptoms.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can you get a concussion without hitting your head directly?
Yes, a concussion can occur from a blow to the body that causes the head to move violently, resulting in the brain shaking inside the skull.
Are women at a higher risk of concussion than men?
Some research suggests that in similar sports, women may report higher rates of concussion and more persistent symptoms, possibly due to differences in neck strength.
Do helmets prevent concussions?
Helmets are excellent at preventing skull fractures and serious open head wounds, but they cannot entirely stop the brain from moving inside the skull during a sudden impact.
Is a concussion more dangerous for someone on blood thinners?
A head injury in someone taking anticoagulants is considered more serious because it increases the risk of internal bleeding, requiring urgent medical assessment.
Can a minor bump in a toddler cause a concussion?
Yes, because their skulls are softer and their brains are developing, even what seems like a minor bump should be monitored closely for changes in behaviour.
How many concussions are “too many”?
There is no specific number, but repeated concussions can lead to longer recovery times and may increase the risk of long-term neurological issues.
