Brain Injury From Car Accidents

Listen to this post from Dr Barry Marks' podcast by clicking the play button

As a doctor who treats many patients with neck and concussion injuries due to car accidents, I am always astounded when I hear that an ER doctor or family medical physician refutes my diagnosis of concussion or mild traumatic brain injury. It is common for a patient to report to me that their doctor says they don't have a concussion or brain injury, further they will often question how a mere "Chiropractor" can make such a diagnosis. I try my best to smile and explain to the patient, that there are indeed standardized methods to medically diagnose a concussion or MTBI as long as the doctor knows how to perform them.

Truth About Concussion, Mild Traumatic Brain Injury Due to Car Accidents

The first thing to understand is the fact that approximately half of all victims in a motor vehicle collision suffers a brain injury. It can be extremely mild and resolve in days, but often they can be more problematic and last weeks, months and in some case indefinitely. The symptoms may be mild like a headache or severe with vomiting, dizziness and inability to think, speak or walk.

Second, realize that you do not need to hit your head to suffer a brain injury. The quickness with which an accident occurs causes your head to jerk very hard very fast. The brain is suspended inside the skull and there is room between the brain and skull. When the head is propelled back very quickly, the brain tends to slosh backwards and strike the interior of the skull bone causing a bruise like injury. This is a simplistic but valid concept of how injuries occur and is well documented in medical literature. A graphic example of a brain injury without an actual head trauma is 'shaken baby syndrome" in which a child suffers brain damage from being shaken too vigorously.

How a Competent Doctor Diagnoses a Brain Injury:

Glasgow Coma Scale

Glasgow Coma Scale (GCS) is a tool to determine level of consciousness of a victim of a traumatic brain injury. The scoring is between 3-15. Subjects with scores of 3-8 are in coma state. Scores of 13-15 are considered mild traumatic brain injury. Some authors describe a score of 15 as a very mild traumatic brain injury. A score of 15 does not mean there is no injury, it merely means the injury is mild. The GCS is a broad tool for screening, it is not very sensitive.


When a patient shows symptoms of brain malfunction after a trauma, a thorough neurological examination must be performed to find subtle clues that a brain injury exists. Checking for pupil response, watching if the eyes stay coordinated with each other during movement, asking the patient to remember and recite common words, asking them to do simple tasks with eyes closed, checking their blood pressure from one side to the other and many other exam procedures are used to "clinically" make a diagnosis.

Standardized Questionnaires

Additionally, other tools such as standardized questionnaires accepted by the scientific and medical community as valid, are used to determine the impact of the symptoms on the patient's daily activities. Questionnaires regarding sleepiness, dizziness, headache, stress related to the accident, etc are all designed to assess the impact your brain injury has on your life and are repeated later after treatment to judge improvement.

A knowledgeable doctor can make the diagnosis through these methods fairly easily, but again they must first understand what tools are available and how to administer and interpret them. Most general doctors do not.

About Mild Traumatic Brain Injuries from Car Accidents

An MTBI is a neurological insult that occurs at the time of the injury and develops over time, usually hours to days. This causes many ER and family practitioners to miss a MTBI. The victim is conscious and to the outside world responsive and "normal," but on closer inspection neuropsychiatric malfunction can be observed. Tests such as x-ray and CT scan are negative for MTBI. MRI's are often not sensitive enough to show the fine neurologic injury, although newer techniques can, but are expensive and few imaging centers have the capability. EEG's are often not sensitive enough to show abnormalities.

Mild traumatic brain injuries should not be regarded as "nuisances" or self-limiting conditions. A MTBI can evolve into Post-Concussion Syndrome (PCS) where symptoms and impairment can last indefinitely.

The medical journal, Brain Injury reports patients with "very mild traumatic brain injuries, (Glasgow coma score 15) "There was a significant impairment in neuropsychological performance (verbal memory, arithmetic abilities and psychomotor reaction time) at onset and after 6 weeks..." "In MRI scans, three patients showed traumatic lesions (slight epidural haematoma, haemorrhagic contusions and white matter lesions indicating diffuse axonal injury)." They concluded "Structural and functional impairment can be identified using neuroimaging and neuropsychological examination, even in very MTBI patients."

If you've suffered a trauma like a car accident and you have a headache, dizziness, fuzzy feeling in your head or find you cannot concentrate well, you may have a concussion. You would be wise to have it evaluated by a doctor specializing in this field to ensure you do not have an injury that will plague you months or years down the road.

Dangerous Lack of Understanding of Head Injuries Among Primary Care Physicians

Does Your Doctor Understand Concussions?

 concussion braon injury car accident

Every day I consult with patients suffering from automobile accident injuries. Approximately half of these patients suffer from concussions. Most of these patients have been to a physician prior to consulting me. Only a small fraction of these patients had been previously diagnosed with a concussion and are surprised when I inform them. More times than not, a concussion will go undetected and undiagnosed in an emergency room and/or a private primary medical physician's or general chiropractor's office after a car accident.

A Concussion otherwise known as a Mild Traumatic Brain Injury (MTBI) is...

A traumatic injury to the brain due to a blow or a sudden jolt that causes the brain to malfunction. It may or may not involve loss of consciousness and it can be very mild or become prolonged.

Dangerous Lack of Brain Injury Education

Probably the most common reason for this lack of understanding is poor education. Medical and Chiropractic schools do not spend much time specifically on the topic of brain injury. The study of brain injuries constantly evolves with advances in technology. Common brain knowledge now far surpasses what was known just a few years ago. Only doctors who have an interest or specialization within this field bother to endeavor to take post-doctorate courses or even read medical or scientific literature on the topic.

Dangerous Myths About Concussions Propagated by Doctors:

“You Can't Have a Concussion—You Did Not Hit Your Head or Lose Consciousness”

“There Is No Treatment for Concussions—It Will Just Take Time”

All too Often, Patients Will Tell Me "My Doctor Said I couldn't Have a Concussion" and Repeat the Above Statements.

Further proving lack of general knowledge on this topic, some patients will report that their doctor is actually miffed that I have made such a diagnosis. When they learn I am a chiropractor it only intensifies their scrutiny. Never mind that I have spent years studying whiplash and brain injuries at the post-doctoral level alongside other chiropractors and medical doctors, but there are criteria and tests published by academic, medical and scientific journals to document, classify and follow up on brain injuries. This is information your average primary care MD or generalist DC have no knowledge of.

2 Problems Caused by Lack of Brain Injury Knowledge

First, brain injuries go undiagnosed leading to long-term health issues, needless suffering, improper treatments, psychological damage to victims and poorer outcomes in personal injury cases. If the concussion is undiagnosed then proper treatment is delayed. Patients continue to suffer from sometimes bizarre and confusing symptoms. Observed by an untrained physician, many people are told they just need to get over it and that it is a psychological problem. It is not uncommon to see a chronic concussion patient to be on anti-depressants and anti-anxiety drugs because they have been told they are just suffering from a psychological disorder. In the longer term, concussions have been linked to more likely onset of Fibromyalgia, Parkinson's and Alzheimer’s diseases.

Second, even if a primary care physician or even a neurologist does recognize a concussion, the most common treatment is rest. Most medical physicians will tell you with all earnest that there are no treatments for mild brain injuries. The problem with that notion is that it is wrong. And since most patients accept the advice of their doctors, particularly specialists like neurologists, they tend to give up on finding further care and then as mentioned earlier end up with long-term suffering. The truth is, treatments DO exist to help accelerate the healing of brain injuries, they just don't happen to be pharmacologically based. In fact, research dating back to the 1960's showed that low light laser therapy can help heal concussions. This research has been ignored by the mainstream medical establishment.

Simple Truths About Car Accident Concussions

Concussions caused by car accidents are common and do not require direct contact with the head. A sudden jolt particularly from behind or the side may jerk the head so violently that the brain is injured. It's the same principle as “shaken baby syndrome.”

It does not take a severe collision to cause a brain injury. In fact, slower speed collision with less vehicle damage are more likely to concuss your brain than higher speed massive vehicle damage collisions. That's because in slow speed collisions there is no bleed off of energy from deforming car parts to slow down the impact so more energy is transferred to the body. A quick pop from behind that jerks your head is a typical mechanism for concussion.

You do not need to lose consciousness to have a concussion. Most concussions do not involve loss of consciousness, but symptoms soon after an injury are usually present.

Tell tale signs of concussion: headache, dizziness, foggy or out of sorts sensation, confusion, disorientation, ringing in ears, difficulty speaking, nausea, vomiting, amnesia, lack of memory or concentration, crying, lack of coordination, blurry vision, face numbness, anger, and more. One or more of these symptoms within moments of the collision is enough to suggest a brain injury and requires an evaluation by a medical specialist trained in concussion detection.

Your symptoms may slowly evolve over a period of days to weeks. This delay in onset of symptoms is not uncommon in mild traumatic brain injury.

There is a lack of knowledge in the medical field about concussions after a car accident.

This leads to misinformation and needless and prolonged suffering. If you've had a car accident, even a minor one and you have the symptoms described in this article and your doctor has told you you’re fine or just give it time, then you owe it to yourself to get checked by an expert in this field. If you do have a concussion there are treatments available to help you.

Transcranial Cold Laser Therapy for Concussion

Transcranial Cold Laser Therapy for Concussion

transcranial laser therapy


Studies have shown that the use of "cold laser" so called because the beam causes no heat, has wide ranging applications for health.

Since lasers were first discovered in 1960, researchers have postulated that focused beams of energy may have an effect on human cells. In 1967, a Hungarian researcher proved just that. Endre Mester showed that hair growth could be stimulated and wounding healing was accelerated in lab mice. Today, Low Level Laser Therapy or LLLT is widely accepted as an effective therapy for pain relief and tissue repair.

Transcranial Laser Therapy

Transcranial laser therapy is the use of cold laser or LLLT to relieve inflammation, stimulate brain cells to regenerate faster and work more efficiently. This treatment is an effective and safe therapy for victims suffering from concussion and mild traumatic brain injury following car accidents, sports, industrial trauma, etc. Standard medical treatment for most concussions involves monitoring and rest leaving it up the body's recuperative powers to heal. This may be alright in very mild cases, but there is growing evidence that if you do not treat a brain injury early, long term prognosis worsens leading to "Post Concussion Syndrome (PCS)." A more active therapy plan for head injuries has been shown to boost healing and get victims back to a more normal lifestyle sooner. An active plan also reduces likelihood of chronic concussion or Post Concussion Syndrome (PCS).

By exposing the body to low level laser light,  photo stimulation occurs activating certain cells (mitochondria) to work more efficiently.  The mitochondria are responsible for energy within your tissues. With up-regulated (improved) mitochondrial function, comes more energy for healing, repair, energy, etc.

Does Transcranial Cold Laser Therapy Really Work?

In the words of the National Institute of Health,

"Many serious brain diseases and injuries can be successfully treated with noninvasive transcranial laser therapy. " (1)

How Much Laser Therapy Does it Take?

Every case is different, but researchers indicate that from 6 to 30 sessions may be required over a period of days to weeks to repair given tissues. The sessions are short lasting less than 15 minutes and are totally painless. Research has shown that longer exposures are actually less effective than short doses over time. Once the mitochondria have been turned on, more energy will not necessarily make them work any more efficient and if they are bombarded for prolonged periods in one sitting, it may actually slow them down.

Suffering from a Concussion, Mild traumatic Brain Injury or other Nerve Condition? Has your doctor told you, you have a concussion but there is nothing that can be done other than wait?

You should consider transcranial laser therapy because:

  • It is effective
  • It is safe with no side effects
  • It is painless
  • It is non-invasive, no shots, no drugs, no surgery
  • It is relaxing
  • It is affordable

Brain Damage without Concussion?

Can Brain Damage Occur without a Concussion?

Surprising New Brain Injury Study

A study of 24 high school football players looked at radiological changes in the brain in the absence of frank concussion. The study presented to the Radiological Society of North America has raised concerns. As part of the Wake Forest Kinematics of Impact Data Set or KIDS, players wore accelerometers on their helmets during practice and games. The accelerometers measured number of hits and the force of each impact. Prior to the season commencing, the 16 to 18 year-olds had diffusion tensor imaging or DTI scans, a specialized form of MRI. These scans are able to visualize fine structures within the white matter of the brain. After the season, scans were repeated and results compared.

Players identified as heavy hitters (9 of the 24 subjects) had appreciable white matter abnormalities in a specific portion of the brain known as the corpus callosum and other deep myelinated nerve tracts. Researchers noted that not one of these players had experienced a concussion that season, yet their brains had been physically altered.
These are the same areas identified as injury points for mild traumatic brain injuries. The corpus callosum is a key part of the brain that serves as the bridge of nerves that connects left and right hemispheres. Damage her can lead to many problems with speech, memory, hand eye coordination, vision and more.

This study only looked at physical and physiologic changes in the brains, and did not assess the athlete’s brain function. An earlier study in 2013 however, found that in Division I college football and hockey players, the more the brains changed physically, the more learning and memory problems were encountered.

“Repeated ‘sub-concussion’ blows to the head may be the cause of damage deep within the brain that leads to cognitive problems later”

Other Causes of Brain Injuries

Of course football and hockey are not the only instances of head injuries. Children whose heads are still developing may be susceptible to changes and therefore cognitive dysfunction from other blows to the head that do not present as obvious concussions. Multiple playground falls, bicycle and skateboard spills, etc over a long period of time may result in serious brain problems.

Auto Accident Brain Injuries

Another obvious vector for brain injury that may go undiagnosed is automobile collisions. Auto collisions involve head accelerations that are many times higher than body accelerations. While concussion is fairly common in car crashes, it is estimated that more head injuries are suffered than are diagnosed. I have definitely seen this anecdotally in my practice. It’s not uncommon for patients to suffer an impact and have signs and symptoms such as headache, dizziness, blurry vision, tongue-tied, tiredness and present to en ER, family medical or chiropractic physician and NOT be diagnosed with concussion. And what of the impact victims who do not outwardly present with brain injury, can they too suffer white matter damage that is silent? I would think so since even a “mild” motor vehicle collision often results in head accelerations greater than a hard football hit.

More Work to be Done About Brain Injuries

Obviously, more research needs to be done and more consensuses reached on diagnosing head injuries and protocols for caring for injured brains. In the meantime, it is incumbent on parents and anyone suffering a jarring of the head, even without direct impact, to look out for changes in mood, memory, coordination and speech to detect subtle signs that the brain is indeed damaged.

Mild brain injuries and concussions are common after car accidents

Many doctors fail to recognize a brain injury in the office unless there was a frank period of unconsciousness. After a car accident that involved jerking or jarring of the head and obviously if you felt your head hit the head restraint or other portion of your car, look for these symptoms:

Feeling dazed or stunned immediately after the collision
Feeling like you are in slow motion or are under water soon after the accident
Wanting to be alone
Difficulty concentrating
Day dreaming/staring
Blurry vision
Double vision
Difficulty speaking/tongue tied
Feelings of isolation from others
Attention problems
Appetite change
Pupils different sizes
Room spins, woozy
Balance problems
Difficulty focusing
Very tired
Dozing during day
Personality changes
Can't remember numbers
Reading problems
Writing problems
Difficulty with adding/subtracting
Poor attention
Difficulty learning new things
Difficulty remembering things
Re-reading to understand things
Difficulty making decisions
Change in sexual functioning
Reduced confidence
Apathy (Don't care)
Change in sense of smell or taste
Flashbacks to accident
Hearing problems
Difficulty planning

If you have more than a few of these symptoms after a car accident or other injury in which your head was either struck or jerked quickly, you may have a brain injury or concussion.

Despite the reluctance of many general practice medical physicians and chiropractors to diagnoses a head injury, the fact is, they occur everyday and in most instances there is no loss of consciousness. If you believe you have some of these symptoms, even if your doctor says you are alright, seek evaluation from a concussion expert right away.

Detecting a Concussion

There are questionnaires a concussion expert or mild traumatic brain injury specialist will ask you to complete. These written tests evaluate certain aspects of brain function in everyday life and can alert the doctor that a possible brain issue exists.

A specific physical examination can then be performed to assess the different areas of the brain for damage and/or malfunction. The exam will test your general neurologic status (reflexes, strength, sensation), your coordination (hand and leg movements, walking), ability to perform simple tasks with eyes open and closed,  your ability to memorize and relay simple information through speech and test your eye movements.

A competent doctor who evaluates and treats many brain injury patients will be able to determine if a concussion exists fairly quickly.

So You've Been Diagnosed with a Concussion... Now What?

Car Accident Concussion Treatment

Many general doctors and even neurologists will tell you there is no treatment for concussions, that it just takes time to heal. That's simply not true.

When the NFL began admitting they had a concussion problem and were taking steps to prevent and treat their players with brain injuries, trainers and sports injury doctors began implementing "a new type of treatment." In fact, a few years back they actually showed this treatment in a segment during the Superbowl. The "new treatment" was actually a treatment that auto accident injury doctors had been using for several years for their concussion patients.

"Newer Treatment for Car Accident Concussions"

Oxygen Therapy

Supplemental oxygen is given to "super oxygenate" the blood stream to get optimum levels of  oxygen to the brain. Oxygen is a basic fuel used by the brain to function. Without proper levels, the brain cannot function let alone heal after an injury.  Oxygen is supplied by a simple oxygenator machine that takes atmospheric oxygen, concentrates it down to 95% oxygen and then pumps it through a nasal cannula for the patient o breathe in. Treatments are typically 15-30 minutes.

Another system of delivering optimum oxygen levels to the brain is hyperbaric oxygen. This is a tube or enclosure that the patient lies down in and is pressurized to 4-7x the normal atmospheric pressure. While in this compressed enclosure, an oxygenator is again supplying supplemental oxygen through a nasal cannula or mask. The high atmospheric pressure makes more oxygen reach the blood.  Typical treatments are about an hour. The only draw backs are discomfort in the ears like flying in an airplane due to altitude and the enclosure can be difficulty for people with claustrophobia.

Cold Laser Therapy

Low light therapy using a laser, so-called "cold" laser because the wavelength of light does not produce heat, has been around for some time. The light stimulates certain components within the cells to enhance their activity.  In essence, the cells are supercharged to effect nerve repair faster and relieve pain and inflammation. Sessions are quick, painless and can be performed at the same time as oxygen therapy.

Brain Exercises

Proprioceptive Exercises may involve movement of the arms or legs, walking with arms and legs swinging in a specific sequence, balancing on one leg or on a ball and others are all aimed at getting the brain to function more normally. These exercises are designed to get the left and right halves of the brain to talk to each other more effectively because many brain injuries from car collisions are centered at the part of the brain that links left and right halves called the corpus callosum.

Vestibular Exercises may include eye exercises in which your eyes track a moving target, or being spun in a chair are used to help with dizziness caused when the brain and/or inner ear are disturbed by trauma.

Cognitive Exercises are things like crossword and word find puzzles that improve thinking performance. Memory games may be given to bolster memory function and concentration often impaired after a concussion.

Brain Rest

Imagine tearing a muscle and instead of resting it, you lifted very heavy weight with it. What would happen? More damage and it would not heal obviously. The brain is no different. With a concussion there is actual physical damage to nerve cells. In order to heal in the best manner possible, the cells need rest so your body can tend to the damage.

While suffering from a concussion avoid:

Computer and TV use ( if you must use them, no more than 30 mins at one time with several hours between uses)

Over thinking, if your job involves high levels of thinking and concentration or you're a student you might want to limit your hours at work or school to avoid over stressing your brain

Any activities that involve bouncing of the head and body such as jogging, running, stair climbing, aerobic exercises, martial arts, cross training, off road vehicles, etc

Take total brain rest at least once each day

Total brain rest means lying in a darkened room with no music or other sounds for 30 to 60 minutes daily. The goal is to limit all input to the brain as much as possible so that it rests.

Dietary Supplementation

The brain needs oxygen and other nutrients to heal. Studies have shown key nutrients are successful at speeding the repair of the brain if taken in correct dosages.  Supplements such as Vitamins A, C, D and E, omega-3 fatty acids, certain B vitamins, lecithin and others can be very helpful in recovering from a brain injury. There are also key food items to avoid if you've suffered a concussion. Artificial sweeteners (Aspartame), MSG, calcium and other items confound brain healing and can prolong recovery.

Concussions and Brain Injuries Take Time

The rate at which your brain recovers depends on many factors, but severity of injury, age, prior history of brain injuries, general health status and willingness to follow treatment plans all play a part. Very mild injuries can resolve in a matter of weeks, while more pervasive injuries may take 2 years. The advice of take it easy and your brain will get better is passe. Today, we know much more about how the brain works, how it becomes injured and what steps can be taken to maximize healing in as short a time as possible. Experience tells us that a positive pro-active approach is superior to sitting back and waiting.
