Mild Traumatic Brain Injury – How to find out if you have a Mild TBI and what to do

A helmet may not protect your head from a mild Traumatic Brain Injury (MTBI), and motorcyclists often sustain a mild traumatic brain injury in a motorcycle accident. According to the Centers for Disease Control and Prevention, 1.7 million people sustain a Traumatic Brain Injury (TBI) each year, and 75% of TBIs are concussions, also known as Post-Traumatic Concussion Syndrome or mild TBI. (Watch the video below.)

What is a Mild TBI?

Medical professionals describe a concussion as a “mild” traumatic brain injury or mild TBI because concussions are usually not life-threatening. The effects of a concussion can be serious and lifelong, which is why a concussion is a “mild” traumatic brain injury. A traumatic brain injury that is not mild is profound or life-threatening.

Is a Mild TBI Really Mild?

No. Medical professionals categorize brain injury as a mild Traumatic Brain Injury (MTBI) or a Traumatic Brain Injury (TBI). But if it happens to you, you won’t think it’s mild. We categorize brain injury as a Serious Traumatic Brain Injury, Severe Traumatic Brain Injury, or Catastrophic Brain Injury.


  • Concussion is an injury to the brain that results in the loss of normal brain function. Its effects can be temporary or permanent. Many times, there are no signs of trauma and no loss of consciousness. It is the most common type of traumatic brain injury.
  • Traumatic means trauma or injury caused by an accident rather than from disease.
  • Post-Traumatic means after the trauma or accident.
  • A syndrome is the association or grouping of several clinically recognizable symptoms.
  • Post-Traumatic Concussion Syndrome is where some of the symptoms below are experienced, having been caused by a concussion that occurred in an accident. This is a mild traumatic brain injury.

What can cause a mild TBI?

A concussion may be caused by a fall, bump, blow, jolt to the head, or whiplash, which causes the head and brain to move quickly back and forth. The resulting concussion can change the way your brain normally works. This can last a short time or even be permanent.

Obviously, this happens in many motorcycle accidents, but it can also happen in car accidents.

In a car accident, your head will be jolted back and forth by whiplash, which can cause a concussion.

In a motorcycle accident, a rider’s helmet may strike the ground, a car, or another object. While a helmet can keep you alive, your brain will be banging around inside two different vessels. Your brain will be banging around inside your head (the first vessel), which is inside your helmet (the second vessel). This is even worse than whiplash from a car accident.

The initial concussion can be the cause of a permanent brain injury, but because concussions are usually unrealized by the injured person and go undiagnosed, a minor concussion can be aggravated in the hours and days after the accident and cause an injury that may have dissipated to become a permanent injury.

Where the initial concussion is not the cause of a permanent brain injury, the inflammation caused by the trauma can cause permanent brain damage.

Inflammation caused by the trauma occurs during the first 48 hours after the accident, and the resulting inflammation can cause damage to the brain, so mild permanent brain damage may not even have been caused at the moment of the accident.

This animation by Medivisuals explains diffuse axonal injury and neuron “suicide and murder.” See how a TBI can go undetected because symptoms may not be immediately observable, and areas of injury and cell death can be too small for traditional CT & MRI to detect. These symptoms may progressively worsen as cell death continues, resulting in devastating brain injuries that do not fully develop until weeks or months after the initial incident.

When to diagnose MTBI

It usually takes a long time before symptoms are recognized and therefore go undiagnosed, as discussed below, so it is vital to look for signs at the time of an accident. Since the very nature of the injury may prevent the injured victim from self-diagnosing the injury, people at the accident scene, family members, and friends are critical to initial evaluation leading to medical follow-up.

MTBI diagnosis should be obtained when one or more of the following indicators occur at the time of the accident:

  • Confusion, disorientation, or impaired consciousness;
  • Dysfunction of memory around the time of injury;
  • Glasgow Coma Scale (GCS) of less than 15 (reported either by EMS or in the hospital) (see also What Is the Glasgow Coma Scale? and video);
  • Loss of consciousness lasting less than 30 minutes;
  • Nausea or vomiting; or
  • Bleeding on or in the brain, usually diagnosed by a CT scan in the hospital, is an indicator of significant head trauma.

Symptoms of mild TBI

Symptoms may begin to show up long after an accident (see why in the next section below). Note that you will not experience all of these symptoms.

One or more of the following symptoms occurring more frequently than usual may indicate you have a mild Traumatic Brain Injury (be sure to let your doctor know):

  • Difficulty thinking clearly
  • Attention problems
  • Difficulty concentrating
  • Poor judgment
  • Impulsiveness
  • Fatigue, feeling tired, slow, or lacking energy
  • Occasional or slight confusion
  • Difficulty remembering new information (mild loss of short-term memory)
  • Difficulty recalling words and names
  • Chronic headaches
  • Severe headaches
  • Fuzzy or blurry vision
  • Hearing loss
  • Tinnitus (ringing in your ear)
  • Dizziness
  • Altered taste and smell
  • Sensitivity to noise or light
  • Balance problems
  • Irritability
  • Being argumentative
  • Sadness or depression
  • Being more emotional
  • Emotional swings
  • Anxiety or nervousness
  • Panic attacks
  • Sudden outbursts of uncontrollable crying or laughing
  • Loss of appetite or increase in appetite
  • Sexual dysfunction
  • Weight change
  • Insomnia or sleeping more than usual
  • Sleeping less than usual
  • Trouble falling asleep or waking up from a deep sleep
  • If a student has a change in grades after the accident
  • If employed, a change in employment records, such as noting difficulties performing tasks or ability to get along with other employees

How soon are symptoms of Mild TBI noticeable?

Symptoms of a mild traumatic brain injury can occur immediately with nausea or vomiting, but the lack of nausea or vomiting doesn’t mean that you did not sustain a mild TBI.

The onset of symptoms may occur days, weeks, or months after a motorcycle accident injury.  However, symptoms are often noticed weeks or months after onset and may be diagnosed long after that, even years later.

Why can it take so long to become aware of or diagnose the symptoms?

  1. Accident victims are acutely aware of the most painful injuries first and later become aware of other less painful injuries after the most painful ones dissipate. Since symptoms of a mild TBI are not painful (except for headaches) and, by definition, are mild, mild TBI symptoms are often overlooked.
  2. When an accident victim becomes aware of his/her symptoms, the person thinks the symptoms will go away and waits and hopes until a long time passes. Eventually, after many months of continuing symptoms, medical advice may finally be sought.
  3. Some accident victims are too embarrassed to admit or tell anyone about their symptoms.
  4. Motorcycle accident victims may be aware of experiencing some of the symptoms but do not realize why they are experiencing the symptoms or that it is because of a mild traumatic brain injury. When we represent a client injured in a motorcycle accident, we look for these symptoms and refer our client to a neuropsychologist for diagnosis when we suspect the possibility of a mild traumatic brain injury.

What can you do if you believe you may have suffered a mild traumatic brain injury?

First, a mild TBI must be diagnosed; and then the injury should be treated

1) Detecting or Diagnosing Mild TBI

A CT Scan of the brain or an MRI of the brain can conclusively show the brain damage but is not necessary to show the existence of mild traumatic brain injury. Most MRI machines of 1.5 T (Tesla), which are low resolution, will miss 40-50% of traumatic brain damage. A  much higher resolution 3.0 T (Tesla) MRI should be used to detect brain damage.

A neuropsychologist or neurologist can also determine if you have suffered a mild TBI, even if not showing on a scan. Sometimes when the patient describes the symptoms to a neurologist, the neurologist will diagnose MTBI and refer the patient to a neurologist who specializes in MTBI or to a neuropsychologist for further testing and treatment.

When we believe that our client may have a mild traumatic brain injury, we will obtain a 3.0 T (Tesla) MRI of the brain when appropriate and refer our client to a neuropsychologist for testing to determine if you have suffered a mild TBI.  We work with neuropsychologists on Long Island who can conduct testing to determine if a mild traumatic brain injury exists.

2) Treating Mild TBI

There is no known cure for MTBI, but patients can be taught how to cope with the disability, and there may be one or more natural supplements that can help.

When diagnosed with a mild TBI, a neuropsychologist will determine in what ways the brain was injured. A neuropsychologist or psychologist can then provide treatment consisting of mental exercises to re-train your brain to use different pathways to perform brain functions.

A neurologist or a psychiatrist can also prescribe short-term medications for mild traumatic brain injury but for moderate to severe TBI, medications can cost as much as hundreds of thousands of dollars over a lifetime and can be recovered in a lawsuit. See a chart showing how different drugs are used and work to treat moderate to severe TBI.

Coping with Behavior Problems after Head Injury is useful for patients, family members, and friends.

A natural supplement believed to be highly beneficial for some recovery is high doses of fish oil with omega-3 fatty acids (see the video below).

An article published in Science, Sept 10, 2021, reported a new potential treatment for long-term complications after brain injury by blocking the C1q molecule that exists in healthy brains. It was reported that the molecule is responsible for chronic inflammation subsequent to brain injury and that it can take years to become noticeable. It was concluded that antibody treatments could help to prevent the development of these side effects in many patients. Perhaps MRNA research will be of benefit for mild traumatic brain injury.

Does a Mild Traumatic Brain Injury Get Worse Over Time?

It appears that the answer is yes. A mild traumatic brain can and probably will get worse over time.

According to UPI, a study published by PLOS One found that military veterans suffered early cognitive decline within only seven years since experiencing a mild traumatic brain injury during combat.

PLOS One reported that the premature cognitive decline found in young veterans with mTBI coincided with elder normative scores and advanced-age subjects with early-stage Parkinson’s disease.

Concussions on TV

On FOX TV News, “The science behind concussions,” Marc Siegel, M.D., NYU Langone Medical Center, and David Samadi, M.D., Lenox Hill Hospital, said — “One smack and you can end up not the same for the rest of your life.” Dr. Siegel wrote on FOX News about Pro Football Hall of Famer and sports broadcaster Harry Carson, “Carson says he has met athletes who suffer a single bad blow to the head during a game in high school and are never the same again.”

How much money can I get if I suffered a mild TBI?  

We settled a case with a concussion for $1.25 million for a 46-year-old woman who did not report headaches until a month after the accident. She did not have any lost income. Her first neurologist stated (misdiagnosed) in her medical records that her headaches were either early Multiple Sclerosis or from prior Lyme Disease. The defense neurologist stated that the plaintiff did not have a concussion and is faking a head injury.

A concussion in a motorcycle accident may be worth much more. The violent trauma of a motorcycle accident is more likely to cause a concussion, and evidence of the injury may be more easily proved. We represented a motorcyclist whose CT scan showed a drop of blood in the brain.  This is absolute proof of the injury. We had a 3D color video made from the CT scan and documented how it has affected his life. A jury gave a $1 Million verdict, and the case was settled for the entire verdict without reduction.

A mild traumatic brain injury can result in a settlement or award for pain and suffering of as much as several million dollars because it is a long-term debilitating injury that can impair your life permanently. Other factors, such as the past and future cost of treatment and medications, increase the value.

While NFL football players may sustain more concussions than motorcyclists, even one concussion can cause a lifetime of problems for an injured motorcyclist. The NFL settled a suit for $765 Million brought on behalf of 4,500 retired players whose lawyers claimed the NFL hid information from them about the dangers of head trauma. However, the settlement of $765 million is a paltry sum amounting to only $170,000 per player and is payable over 20 years!

Legal analysts estimated that the lawsuit was worth $2 billion. The NFL player’s attorneys may say that the settlement was hastily made to get funds to football players quickly, but I think the dramatically low settlement was the result of poor negotiating skills on the part of the player’s lawyers, and I think I could have done a lot better. The real issue in the lawsuit is whether the NFL hid information from the players.

The New York Times reported that the National Football League stated in federal court documents that it expects nearly 1/3 of retired NFL players to develop long-term cognitive problems, which are likely to begin at “notably younger ages” than in the general population. This newly revised estimate is probably even lower than what the NFL really believes. The number of players suffering from brain injuries due to concussions is staggering, especially considering that not all players have had a concussion. The report does not say how many have had a concussion.

Proving a Brain Injury

There are many ways we prove a brain injury, such as using medical records and experts like a neuropsychologist.

The video below was made to show to an insurance company so they can see what happened to our client’s brain instead of just reading medical records. The insurance company offered only $150,000 to settle, and the video was shown to the jury at the trial. A jury gave a $1 Million verdict, and the case was settled for the entire verdict without reduction.

Our client hit his head in a motorcycle accident, and he didn’t even know he had a brain injury.  He complained of memory issues, and when we received his hospital records, we found a CT scan report which showed he had a small hemorrhage.

Doctors categorize a brain hemorrhage as either small or large. A brain hemorrhage is often described in medical records as small because a mid-line shift of the brain is needed before it is considered large. Since this encompasses a large range, the video is useful to show that small is still bad.

A mid-line shift of the brain would require 24-hour care for a person injured in an accident or would be deceased.

We created this video from his 2D Black & White CT scan. This video shows the “small” hemorrhage (bleeding) in his brain in 3D color and also contrasts side by side with the 2D Black & White CT scan.
