to Glossary Index ]
A neuropsychologist is a psychologist who has taken required
courses in neuroanatomy, neurophysiology and neuropathology
and who understands the complex interrelationships between
brain function, personality and behavior. Currently only a
small number of neuropsychologists are certified by either
the American Board of Clinical Neuropsychology or the American
Board of Professional Neuropsychology, and very few are certified
by both. Some practitioners assess but do not treat
patients. Such practitioners are consulted by physicians (and
occasionally by attorneys) and asked for a report commenting
upon the presence, type and extent of cognitive dysfunction,
and its likely cause(s). Others counsel patients with neurologic
disorders (such as TBI or stroke) to understand and accept
their limitations and learn compensatory techniques to improve
daily functioning, such as using daily planners, memory aids
and avoiding situations which cause an overload of stress
or fatigue. Some are pure clinicians who will not work with
attorneys. Some only do forensic work for attorneys in the
legal arena. Many do both.
Neuropsychology has developed rapidly over the past 20 years.
It is a commonplace today for a neurologist who suspects TBI
to refer a patient for testing by a trusted neuropsychologist.
Prior the advent of CT and MRI, neuropsychologists focused
on locating the lesion in the brain by interview and written
testing of cognitive capacities. Today they focus much more
on the functional impact of brain damage on a patient's life
activities including work, family, recreation and leisure.
The one exception is "mild" TBI which remains invisible
on CT and MRI. Two figures who had enormous influence on neuropsychology
were Norman Geschwind, MD of Boston Hospital and Ralph Reitan,
Phd of Arizona. Dr. Geschwind founded the field of "behavioral
neurology" premised upon the observation that structural
damage to neural circuitry in the brain from injury or illness
had profound effects on the behavior of patients. Dr. Reitan
(first student, then collaborator, then successor to Ward
Halstead of the University of Chicago) developed a fixed battery
of neuropsychologic tests which were sensitive to and specific
to brain injury. Although modern neuropsychology tends much
more to utilize the flexible rather than the fixed test battery,
Dr. Reitan was an important pioneer in the field.
