Brain Injury in Service and its Relationship to Mental Health – Talking About Men’s Health

Concussion Legacy Foundation

Author: Samantha Bureau, PhD

In September, we come together to raise awareness about concussions so that more individuals and families know what to do in the event they or their loved one sustains one.

A concussion is a type of traumatic brain injury, or TBI, caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth. While concussions are usually not life-threatening, we still need to treat them seriously as the effects of a concussion can change a life.

This Concussion Awareness Month, we especially want to raise awareness that concussions do not exclusively happen in sport.

While we often see and hear stories about former contact and collision sport athletes struggling with the impacts of single and repeated brain injuries, we know that brain injury impacts a far broader demographic, including kids on the playground, accident survivors, and those with higher risk occupations, such as our service members and first responders. Some ways brain injury may occur within this community include airborne training, breaching, exposure to blast, combat training, firing artillery, sports participation, falls and accidents, and motor vehicle collisions.

According to the DOD Traumatic Brain Injury Center of Excellence, more than 485,000 service-members sustained a traumatic brain injury since 2000.[1]

We also know that brain injuries are largely under-reported, so there are likely many more service-members who have sustained a brain injury in service, and many more who sustained a brain injury outside of service in their day to day lives. We also know that our first responders are at risk of brain injury. A recent study on first responders showed an alarming 74% of police officers studied reported a history of at least one brain injury, with 30% reporting at least one injury sustained on the job.[2]

This study also noted that many of these injuries went unreported and untreated.

Without the help of a medical provider and proper treatment following a brain injury, the likelihood of prolonged symptoms and difficulties increases. This is why recognizing and reporting brain injuries is of the utmost importance.

In the event you or your loved one sustains a concussion, here are some signs and symptoms to be aware of:

Concussion Signs Include:

• Problems with balance
• Glazed look in the eyes
• Amnesia
• Delayed response to questions
• Forgetting an instruction, confusion about an assignment or position, or confusion of the game, score, or opponent
• Inappropriate crying
• Inappropriate laughter
• Vomiting
• Loss of consciousness

Common Concussion Symptoms:

1. Somatic (Physical) Symptoms

• Headache
• Light-headedness
• Dizziness
• Nausea
• Sensitivity to light
• Sensitivity to noise

2. Cognitive Symptoms

• Difficulties with attention
• Memory problems
• Loss of focus
• Difficulty multitasking
• Difficulty completing mental tasks

3. Sleep Symptoms

• Sleeping more than usual
• Sleeping less than usual
• Having trouble falling asleep

4. Emotional Symptoms

• Anxiety
• Depression
• Panic attacks

As we continue to learn more about how concussion impacts this community, one area of research that has gained attention more recently is on the relationship between brain injuries and mental health outcomes.

A 2019 systematic review and meta-analysis from researchers at Harvard University researchers has shown that a single traumatic brain injury can double your risk of suicide.[3]

And this is not the only study that has linked negative mental health outcomes to brain injury. A 2022 study from the Children’s Hospital of Eastern Ontario (CHEO) demonstrated that children diagnosed with a concussion were 40% more likely to develop a new mental health disorder following their injury than children diagnosed with an orthopedic injury.[4]

But does this also apply to our service members and first responders?

The answer is yes.

A 2023 study reviewed the records of more than 860,000 US military service members and demonstrated that soldiers with military related traumatic brain injury had significantly higher rates of new-onset mental health conditions than those without a TBI. Those individuals were also at increased risk for suicide.[5] Additionally, the study that showed 74% of police officers reporting a history of brain injury also found the officers with a history of brain injury had increased rates of PTSD and depressive symptoms than those who did not report a history of brain injury.²

If you are reading this and are struggling with the impacts of brain injury, we are here for you.

Whether your injury was recent or years ago, if you are still experiencing symptoms and don’t know where to turn, the Concussion Legacy Foundation can help.

Our CLF HelpLine and Peer Support programs offer opportunities for you to get the help you need from a trusted team.

Whether you need help finding medical providers in your area, or you are just looking for someone to talk to who understands your situation, we encourage you to reach out to us at CLFHelpLine.org.
