Treatment of
Brain Injuries and Mental Illness

INTRODUCTION

Brain function remains a great mystery to all people, despite the intense focus on it over the last several decades.  Research on the brain, how it functions, and treating its disorders has exploded over the past several decades, and yet problems and disorders of the brain are still not well understood. For example, an academic database search (EBSCOhost) reveals that there have been 157,508 scholarly and research articles on mental illness, with 97,370 occurring since 2009 and 138,555 research articles specifically focused on concussions, with 107,241 occurring since 2009.  To put the exploding interest in concussions (and traumatic brain injuries) and mental illness in perspective, 62% of all research articles published on mental illness and 77.4% of all research articles on concussion have been published since 2009.  Despite this research focus on mental health and brain injuries both are often misdiagnosed and even more frequently inadequately treated.

 

BRAIN FUNCTION OVERVIEW

In order to effectively treat concussions, brain injuries, and mental illness (CBIMI) there must be an accurate understanding of the brain and how it functions.  There are thousands of research articles on CBIMI, many of which are devoted to animal models of brain injury or mental illness, neurotransmitter function and its relationship to CBIMI, oxygen to the brain, blood flow to and within the brain, genetics and its role in CBIMI, trauma and how it affects CBIMI, relational factors contributing to CBIMI, etc.  Interestingly, despite the hundreds of thousands of scholarly, research articles on the topic there has been no definitive answer or scientific agreement on the cause of depression, the reason why mood-stabilizing medications reduce manic symptoms in Bipolar Disorder, or curative treatment for concussions, traumatic brain injuries, or post-concussion syndrome.

The basis for effectively treating CBIMI is a fundamental and correct understanding of brain function.  The brain must be adequately fueled if it is to function appropriately (Glenn, T.C., Martin, N.A., Horning, M.A., Hovda, D, 2015; Cunnane, S.C., Corchesne-Loyer, A., Vandenberghe, C., 2016) .  There has been renewed interested in ketones as a source of brain fuel, per the articles cited in the previous sentence as well as other research, but ketones and the ketogenic system are a secondary fuel source at best and are activated in the case of crisis and starvation (Fann, S. 2019).  As will be explained later in this paper, glucose is the primary fuel source for the brain.

All areas of brain function that were previously identified as the subjects of extensive research (neurotransmitter function, oxygen supply to the brain, blood supply to the brain, and others) are important and necessary for proper brain function but cannot function properly without adequate fueling.  Consider the example of how a car functions.  The transmission and drive shaft may work fine, but if the fuel filter is clogged the engine will not run smoothly and the car will not move as it should.  This does not mean that there are mechanical problems with those parts but rather the lack of consistent fuel makes them not operate as intended.    The brain works in the same manner.  When it is fully fueled all the “mechanical” parts and systems function appropriately; when it is not receiving adequate fuel there are “mechanical” problems with the neurotransmitters, brain structures, and basic human functions (memory, attention, emotional regulation, behavioral control, etc.).  Unfortunately, researchers are incorrectly assuming that there is a “mechanical” problem in the brain and so are looking for and finding ways in which the “mechanics” (neurotransmitters and brain structures, among other things) are not functioning as they should and inaccurately identifying those things as the brain’s problem and source of functional deficits (Patterson & Holahan, 2012).  An accurate understanding of brain function leads to identifying the source of the problem, which is inadequate or inconsistent fueling.

 

CAUSE OF BRAIN DYSFUNCTION

Trauma is the factor that is responsible for inadequate or incomplete fueling of the brain and corresponding brain dysfunction.  Trauma for the purposes of this paper and brain function is defined as any event or experience that activates the sympathetic nervous system, the fight/flight/freeze response, and corresponding brain fuel limitation.  Trauma occurs primarily in the form of concussive injuries, traumatic brain injuries, experiences of fear, and psychological injuries in the form of neglect, emotional abuse, physical abuse and sexual abuse.

When the sympathetic nervous system is activated by concussion, traumatic brain injury, fear experiences, or psychological injuries extra energy or fuel is required by the brain to ensure the person survives (Flak, J.N., Arble, D., Pan, W., et al., 2017).  The brain creates a chemical cascade when it is activated by fear, danger, or injury, which results in it receiving extra fuel from the body.  The infusion of extra fuel contributes to the development of hyperglycolysis, which is not a normal brain process and can be harmful and dangerous to the brain if it persists (Giza et al., 2001; Jalon et al., 2015; Hovda et al., 2011).  As a result, the brain begins limiting the amount of fuel it requires from the body and does so permanently with each physical or psychological injury, experience of fear or danger, and activation of the sympathetic nervous system (Glenn, T.C., Martin, N.A., Horning, M.A., Hovda, D, 2015) .  This fuel limitation is “permanent” (until the fuel dysfunction is eliminated through treatment, which will be explained in detail below), because the brain actively works to eliminate the risk of a re-occurrence of hyperglycolysis (Zetterberg, Smith, Blennow, 2015 ).

The fuel limitation caused by activation of the sympathetic nervous system due to the injuries noted above is not only “permanent,” but is cumulative (Daneshvar, D.H., Riley, D.O., Nowinski, C.J., McKee, A.C., et al, 2011; Guerriero, R.M., Giza, C.C., & Rotenberg, A., 2015).  Each sympathetic nervous system activation and injury results in hyperglycolysis, which the brain interprets as not only dangerous but as representing increased risk of additional episodes of hyperglycolysis, resulting in the need for additional limitations on fuel (Zetterberg, Smith, Blennow, 2015).  When each subsequent trauma occurs, the brain responds with additional limitations on the amount of fuel it receives in an effort to reduce future episodes of hyperglycolysis and prevent serious damage and even death.

Fuel limitation results in reduction of efficiency or effectiveness of all brain functions.  This reduction in efficiency and effectiveness is experienced as symptoms of brain disorders and mental illness.  The abilities that are most commonly thought of as the primary domains of brain function such as memory, attention and concentration, language skills, reading, math, and information processing are reduced or limited due to inadequate fuel as described above.  The abilities and functions that are thought of as being the primary domain of psychology such as emotional regulation, interpersonal relatedness, and behavioral control are also reduced or limited due to inadequate fuel.  The symptoms of mental illness, such as anxiety, depression, lack of anger control, excessive inhibition in social situations, aggressive or violent behavior, and perhaps even mania and psychotic symptoms are due to the brain’s inability to regulate these behaviors and experiences appropriately because there is not enough fuel to do so.

Current research is also pointing towards the role of inadequate brain fuel in what have been considered primarily or exclusively physical symptoms, such as the muscle weakness in multiple sclerosis, the seizures of epileptic disorders, fainting, and even the symptoms of auto-immune disorders.  This research is quite recent and should be considered tentative.

 

BRAIN FUEL

The brain is fueled by a number of chemicals and substances, but its primary fuel is glucose, which is also a primary fuel for the rest of the body.  Cellular respiration (or the process of creating energy for the body) cannot occur without glucose.  It’s importance in the body is further illustrated by the fact that there are two specific substances in the body whose entire function is to regulate the availability of glucose to the body and the brain, glycogen and glucagon (Chobot, A., Otto-Buczkowski, E. 2011).

The process of brain fueling begins with the body converting a portion of everything that is eaten to glucose.  Glucose is used to fuel the body and the brain and any “extra” that is not used for those two purposes is converted to glycogen and stored in the liver and elsewhere throughout the body.  The liver releases glucose as needed via glucagon, which converts glycogen back to glucose and then can be used by the body for fuel and energy (Chobot, A., Otto-Buczkowski, E. 2011) .

The brain consumes approximately 20% to 40% of all glucose created by the body via the above mechanism (Mergentheler, P., Lindauer, U., Dienel, G., et al., 2013; Harvard Mahoney Neuroscience Institute, 2019).  It consumes more glucose than any other organ or process in the body.  The brain allocates glucose first to the brain stem, which is responsible for the heart pumping, respiration, and other survival-necessary functions.  Following fueling of the brain stem, then glucose is allocated geographically and functionally through the sensory and motor functions and organs up to the outer-most layer of the brain, the cerebral cortex.  The cerebral cortex is primarily responsible for higher-level brain functions such as thinking, memory, language, vision, and other domains of human expertise.

As was described above trauma results in the process of hyperglycolysis, which results in the brain limiting the amount of glucose it allows to come in to it from the body.  The limitation of glucose is the limitation of brain fuel, resulting in the symptoms of CBIMI (Burns, C.M., 2015).  In most cases, the symptoms following a first trauma (brain or psychological) are minimal and transient, so much so that first traumas (unless they are severe enough to result in loss of consciousness) are undetected.  The explanation for this is that each traumatic event results in a relatively minor reduction in glucose provision to the brain, and the brain can adapt and adjust to the minor limitation in glucose availability.  Due to the cumulative nature of these injuries, and the successive decreases in glucose availability to the brain following each injury, symptoms increase in frequency and severity as the number of experienced traumatic events multiply.

At the time of first trauma there may be brief, mild headaches, tiredness, transient blurry vision, or other similarly mild symptoms.  These symptoms usually continue for a period of hours and then seem to completely disappear.  In reality, the symptoms continue but are misinterpreted by the brain as “normal” or “sinus” headaches, expected tiredness or fatigue due to stress, “laziness,” “normal teenage moodiness”, or a variety of other “normal” conditions.  The brain utilizes a variety of methods (including the symptoms noted above) to signal a reduction or deficit in fuel, but until now those methods have been misinterpreted and not associated with glucose (or fuel) deficits at all.

Typically, as the traumatic injuries accumulate, symptoms associated with the functions of the cerebral cortex (memory, language or word-finding problems, attention/concentration, etc.) and symptoms related to the pain and pleasure centers of the brain (headaches, painful sensory experiences, etc.) are most common and become more “permanent” (Maruta, J., Spielman, L.A., Yarusi, B.B., et al., 2016).  Sensory changes, which are frequently connected to the organs and systems in the geographically mid-level of the brain, occur more frequently in the senses of vision (light sensitivity) and hearing (sound sensitivity).  In more severe injuries, or after experiencing a higher number of injuries, the senses of taste and smell begin to be affected.  The last symptoms to appear are impairments in motor function, systemic deterioration, and finally in cases of repeated or severe injury, death.  The symptoms of trauma and the corresponding glucose limitation are “permanent,” until treated appropriately (Zetterberg, Smith, Blennow, 2015).

 

TREATMENT OF CBIMI

The first and most important treatment for CBIMI is taking over-the-counter glucose tablets, gummies, or dextrose powder mixed in liquid.  Glucose taken in these forms by-passes the brain’s glucose-limiting mechanism, which occurs following trauma as described above.  In this way, the brain is fueled directly and responds very quickly to receiving fuel.

The brain must be fully fueled with over-the-counter glucose throughout the day.  This typically requires 3-4 doses of glucose spread evenly over the course of the day.  The principle is as simple as the need to re-charge the battery on your cell phone.  When the battery level drops below 5 or 10%, in most phones, the screen is darkened and the phone will not function as designed.  When the glucose level in the brain drops below a certain level due to using it up through activity or stress brain function diminishes, symptoms like headache, dizziness, and brain fog emerge, and there are often sensory difficulties such as tinnitus, light sensitivity, and sound sensitivity.

During the several months of treatment, as the brain remains adequately or fully fueled, the brain begins to decrease the limiting factor and allows more of the glucose that is naturally produced by the body from food to enter it.  This results in the ability to reduce the amount of glucose taken with each dose, because now the brain is receiving a higher percentage of the glucose created by the body.

Glucose treatment of CBIMI typically requires 3-6 months of taking the glucose 3-4 times per day.  After this amount of time the brain chemistry re-sets, and the limiting factor is no longer occurring.  As such, glucose treatment can be discontinued in approximately 3-6 months, with no return of symptoms following discontinuation.  All cognitive symptoms (thinking difficulty, memory difficulty, word-finding difficulty, language difficulty, information processing difficulty, attention/concentration difficulty, etc.), psychological symptoms (anxiety, depression, anger management difficulty, mania, psychosis, emotional numbness, anhedonia, low motivation, poor self-esteem and inaccurate self-perception, feelings of worthlessness, etc.), behavioral symptoms (“laziness,” aggression, violence, isolation/withdrawal, etc.), and many physical symptoms (headache, migraine headache, tinnitus, light sensitivity, sound sensitivity, balance difficulty, many pains, limited mobility, tremor, seizure, etc.), (Wallace et al., 2016) are eliminated following the 3-6 months of glucose treatment.

In addition to the glucose treatment the person with CBIMI must participate in a modified form of cognitive-behavioral therapy (CBT).  The brain misinterprets what has happened with the experience of trauma and there are resulting thought patterns that need to be modified.  It is common for the brain to cycle through a variety of misinterpretations as it is recovering, each of which must be addressed and changed to accurate thought patterns.  When CBT is attempted without adequate fueling it can be successful, but it takes much more time, is much more difficult, and can lead to subtle maladaptations in other areas of brain function (such as worsened memory, development or exacerbation of headaches, etc.).

Finally, after the brain has been adequately fueled with glucose for a period of a few weeks to a few months, training of peripheral physical systems, such as in visual information processing and balance, frequently must be provided (Bigelow, R.T., Semenov, Y.R., duLac, S. 2016).  Many clinicians attempt to provide vision training immediately after the trauma, which leads to compensations that are not helpful and can increase or exacerbate headaches.  Vision training in most cases consists of several sessions of learning the exercises and then completing the exercises at home for a few minutes each day.

 

SUMMARY

A vast body of research is accumulating on concussions, brain injuries, and mental illness (CBIMI).  Unfortunately, this research is focusing more on the “mechanics” of brain function than on the foundation of brain function, which is the fueling (or lack of fueling) of the brain.

Traumatic experiences (either through head injuries or psychological trauma) are defined as anything that results in the activation of the sympathetic nervous system and subsequent limiting of glucose (or fuel) to the brain.  This glucose limitation is “permanent” and increases following every traumatic experience that is sufficient to activate the sympathetic nervous system.  Every traumatic incident is cumulative in its effect on limiting brain fueling or glucose delivery to the brain.

Treatment with a combination of over-the-counter glucose that is taken orally, in combination with a modification of cognitive-behavioral therapy and brief peripheral physical system training is effective in eliminating the effects of CBIMI.
