Traumatic Brain Injury (TBI)

TBI Statistics

These alarming statistics affect all communities. Since the advances of medical technology, health care has become more specialized, and sub-specialized. However, who does one see to help diagnose and treat a suspected head injury? A Family Doctor?….. A Neurologist?…… A Psychologist?…. A Radiologist?…. What about a Neuropsychologist?….. so many to choose from, but which one would be most helpful?….. The answer is that they all offer an important piece to the puzzle.  For example, Sevan (a fictitious name of a patient) was 21-years-old, when he became involved in a motorcycle accident on Christmas day. An intoxicated truck driver collided with his motorcycle while making a left turn on a green light. Sevan was ejected from the seat of his motorcycle and subsequently landed in the middle of the street. While he had no memory of the accident, eyewitness accounts notified paramedics and reported the accident. After the paramedics rushed him to the emergency room, he regained consciousness after 5 hours of being in a coma. While he did not sustain any major physical injuries, his family noticed a drastic change in his behavior and thinking. He lost his ability to read words, and experienced difficulty with attention, concentration, memory, and behavior (i.e., short-temper, aggression, irritability, impulsive). According to his mother, “his son had changed since the accident, and she was desperate to find someone who could help him. Therefore, his mother took Sevan to his family doctor who ordered some brain imaging diagnostic tests (CT and MRI scans) and referred him to a long list of specialists (e.g., neurologist, psychiatrist, etc.) to clarify his condition. His mother wondered about all these doctors…. what did they do? How would they be able to help Sevan?


A neurologist is a physician (MD or DO) who specializes in diseases of the brain and nervous system. Although they overlap a bit with psychiatrists because they share the same organ (brain), they tend to concentrate on physical manifestations of neurological problems, or problems related to abnormalities in the structure or function of specific regions of the nervous system. They deal with the brain, spinal cord, nerve roots, nerves, and muscles. Psychiatrists (aka MDs) deal with emotional and cognitive disorders, such as schizophrenia, depression, panic disorders, etc. A neurologist performs a neurological examination and provides crucial information about the nervous system. It is a non-invasive way to find out what might be wrong. It typically includes an examination of the 12 nerves of the head and neck, reflexes, balance and coordination, muscle strength and movement, mental status awareness and response to the environment, appearance and general behavior, orientation, attention and memory. Neurologists also perform diagnostic tests, such as lumbar puncture, electroencephalography (EEG), and electromyography/nerve conduction velocity (EMG/NCV).

Based on the results of the neurological exam and the diagnostic tests (EEG, EMG, CT, MRI), a neurologist is likely to refer a patient with a head injury to a Neuropsychologist for an understanding of which brain functions are impaired and which remain intact. A neuropsychological evaluation will be able to tell how the injury specifically affected thinking and behavior.


Neuropsychology comes from the Greek word “neuron” meaning “nerve,” the Greek word “psyche” meaning “mind,” and the Greek word “logos” meaning “the study of”. Put the words together and you have….

The scientific study of brain-behavior relationships and the clinical application of that knowledge to human problems…in simpler terms, Neuropsychology is the study of how different disorders of the brain (i.e., traumatic brain injury, concussion, aneurysm, stroke, dementia, tumor, etc) affect a person’s thinking, emotion, and behavior.


A Neuropsychologist typically holds a doctoral degree (PhD) in Clinical Psychology/Neuropsychology from an accredited university or professional graduate school. A Neuropsychologist may also have completed additional graduate-level coursework in Neurosciences, such as Neurology, Neuroanatomy, Neuropathology,  Neuropsychological Assessment,  Neuroradiology, etc.

He/she must be a licensed psychologist with specialized training and experience in the field, which include a predoctoral supervised Internship in psychology and Neuropsychology, followed by 1-2 years of Postdoctoral Fellowship in Neuropsychology.


A neuropsychological evaluation is a comprehensive evaluation of cognitive, behavioral, and emotional functioning performed using standardized tests and procedures. A Neuropsychologist uses a wide variety of paper/pencil and computerized tests that are very sensitive to even mild brain dysfunction. Typically, the evaluation includes 60-90 minutes of clinical interview about your problems and background (childhood, education, occupation, family, medical and psychiatric history), followed by 4-6 hrs. of formal testing. The evaluation can be scheduled for a single day or divided into several days, depending on the fatigue level and time. In addition to time spent face to face, time is required to review records, score, interpret the tests and generate a report. This could add an additional 4-6 hours. After the completion of the report, the Neuropsychologist reviews the results of the evaluation with the patient and his/her family and makes treatment recommendations. A copy of the report is also forwarded to the referring physician and other health care providers.


A Neuropsychologist typically evaluates how the brain functions in the following areas:

  • Intellectual abilities
  • Attention/Concentration
  • Learning and Memory
  • Language
  • Problem solving, planning and organizational skills
  • Reasoning and Judgment
  • Perceptual and Motor Skills
  • Visual-spatial skills
  • Academic Skills
  • Emotion, Behavior, and Personality


The results of a neuropsychological evaluation can help your doctor clarify weaknesses, differentiate among illnesses (Traumatic Brain Injury vs. Stroke vs. Alzheimer’s vs. Depression), establish a “baseline” before surgery or before problems are seen, and plan treatment that uses strengths to compensate weaknesses. The results can also help the Social Security office determine if you qualify for Disability benefits. Following is a sample of some of the many questions that can be answered by a neuropsychological evaluation:

  1. *Do I actually have a brain injury?
  2. What is the cause of my problems? Is it medical, emotional, neurological, or stress?
  3. **All neurological, physical, and imaging (CT & MRI scans) tests are normal, why do I still  have difficulties doing everyday things?
  4.  Would I be able to return to work/school, drive again, or play golf?
  5.  Am I getting better? How much?  Is treatment helping me?

*This is especially true following “mild” brain injury, when the effects of an injury may be subtle and easily confused with other factors, such as stress, medications, or depression.

 **Just because a skull  X-Ray or CT/MRI scans of the brain are negative (normal) does not mean everything is fine. You can still experience difficulties in thinking, emotion, and behavior that affect your quality of life.  Because CT/MRI measure structure, not function or behavior, a Neuropsychological Evaluation is recommended especially when problems persist.
