CHAPTER 2

From Head to Tail … What is the BHET Method?

WHEN CONSIDERING THE field of traumatic brain injury (TBI) and concussion, I am reminded of lyrics by Jimmy Cliff, a famous reggae artist who said, “There are more questions than answers, and the more I find out is the less I learn.” Despite years of scientific research on brain injuries, the experience of highly trained clinicians, and the support of families and foundations, we face the disadvantage of several unanswered questions.

According to Kenzie et al., TBI can be referred to as “the most complicated disease of the most complex organ of the body”.

The Brain Hierarchical Evaluation and Treatment (BHET) method challenges the current methods employed to evaluate and treat persons with TBI, while also providing an explanation for the hierarchical disorganization and subsequent reorganization that occurred in Mario’s brain and the over 50 million victims worldwide who are also affected by this condition each year.

BHET further provides the basis for carrying out treatment through various dimensions and domains to understand this very complex condition. The treatment and outcome will be covered in Volume II of this series.

Given the recent attention gained by the field of concussion and TBI, clinicians and patients are at a stage where they can no longer wait for answers to fundamental questions regarding how to properly evaluate and treat these conditions. The questions about the outcome of a specific health concern form the basis for what we believe subsequently and how we act: When will someone emerge from a coma? Can I overcome the phobia of going out in public? Is the dizziness and vertigo (spinning sensation) permanent? Why can’t I multitask and not be distracted? What about the problems pertaining to memory and anger management … will they ever go away? Will I ever be able to enjoy a good night of sleep? Should I stop this medication that I am using for seizures? Can I ever drive again? What about my sexuality? What about the restoration of my rights as an individual and will I ever be able to work again?

While the issues of concussion and TBI have been popularized in the modern media, there remains a lack of understanding among all stakeholders regarding the longitudinal issues in time and space that confront society related to this kind of injury. Brain injury as a concept is unlike any other condition, in that it impacts the computer-like processing system that directs the physiology of our bodies and how they operate, who we are, and what others perceive us to be. In fact, it is not merely about the health care provider and the patient; it involves a web of societal concerns, including the family unit, our policymakers, the legal system, funding sources, research interest, media, and our social organization. Those affected by this condition know very well the challenges it poses to our quality of life, economic stability, and social order.

Very few physicians have been interested in learning about TBI/concussions due to the limited understanding of the brain and the complexity of the science, the patients, and the issues. While extensive research has been done in the field, the results of TBI/concussion research have been “hampered by imprecise classification, methodological inconsistencies, measurement issues, and uncertainty about underlying pathophysiology” according to a paper published by Erin Kenzie and colleagues in 2017 (Kenzie 2017).

As of 2014, the total estimated cost incurred for failed clinical trials in TBI/concussion in the USA is over 1.1 billion dollars (ASPE 2014). In terms of the treatment, as of 2016, over 30 major clinical pharmaceutical trials to treat TBI have been conducted, and they have all been considered to have failed (Hack 2016).

As a treating neurologist for over three decades, I see a level of disorganization in our field, which has caused chaos among the stakeholders. I believe this disorganization is fundamentally due to our lack of understanding in how the brain is truly organized, how injury impacts organization, and how the brain reorganizes during recovery. This reorganization affects the patient, as well as the social order in the world.

I have been both humbled and humiliated by the patients I have met over the years and how much they defy medical wisdom at times. After spending three decades with over 250,000 patient encounters whom I have observed, evaluated, and treated, I have developed “Brain Hierarchical Evaluation and Treatment” or in short, the BHET method. The BHET approach utilizes the concept of organizing the subject of brain injury in various dimensions and domains to evaluate and treat patients with brain injury. The information in this book is not new, but I have utilized my experience to help clinicians, patients and their families, and the public find a more organized and efficient way to evaluate and treat TBI and concussion. This approach is evidence-based as well as clinically relevant. While this book questions and occasionally, objects to many of the current approaches used by clinicians, administrators, caregivers, and families, it utilizes research data available in the medical literature, my experience, and the experience of my colleagues in designing the BHET method. This first volume addresses how the brain works normally, following injury, and during recovery. The second volume will address the prognosis, outcomes, and the various methods of managing and treating TBI and concussion.

The BHET method is based on an understanding of the complexity of the human nervous system: its design, structural and physiological organization, and its adaptive and preservative capabilities after an injury. As the title suggests, “From Head to Tail” defines the inner workings of the nervous system, from its most complicated functions and structures, defined as “head behavior”, to its simpliest and primitive reflex behaviors, known as “tail behavior”.

As a neurologist with specialized training in neurological rehabilitation and neurological trauma, I have examined and treated TBI/concussion patients in the emergency room, trauma center, intensive care unit, acute care hospitals, inpatient neurological rehabilitation centers, outpatient rehabilitation centers, sub-acute facilities, and in out-patient settings. As the former Medical Director of Neurological Rehabilitation at Jackson Memorial Hospital and in my current roles as Medical Director at the University of Miami Miller School of Medicine Sports Medicine Concussion Program, Medical Director of Kendall Regional Medical Center Intermediate Brain Injury Unit, and Managing Director of the Design Neuroscience Center, I feel honored by this opportunity to serve this population of patients. I have seen first-hand the destruction of the hierarchical organization of the nervous system and observed with interest the recovery and restoration process of the structural, physiological, and corresponding functional hierarchical organization. BHET results from the knowledge I acquired in neuroscience, with major guidance from the experience of others, training from my teachers, my experience in the business, and in actually treating patients by utilizing the science presented by medical literature and some trial and error. BHET is an approach that has worked for patients with brain injury of all types, although the focus of this work is mostly on concussion and TBI.
