| What is the Purpose of a Neuropsychological Evaluation?
A neuropsychological evaluation is used to obtain several
types of information. Reasons you have been referred for
a neuropsychological evaluation may include, among others:
1)
to find possible problems with your brain functioning,
2)
to help lead to a diagnosis,
3) to define your brain-related
strengthsand weaknesses,
4) to guide treatment for your personal, educational or vocational
needs, and make relevant recommendations to your other health
care provider(s), or
5) to document possible changes in your functioning over
time.
What is a Neuropsychological Evaluation?
A neuropsychological evaluation typically involves assessment
(testing) with a group of standardized tests that are sensitive
to the effects of brain dysfunction. Unlike CT or MRI scans
which show abnormalities in the structure of the brain, or
EEG, which shows electrical abnormalities in the brain, neuropsychological
assessment is used to show the ways in which a person can or
cannot perform certain functions or tasks that are dependent
upon brain activity.
These functions or tasks (for example, memory
and learning) form the necessary building blocks of successful
living in the individual's daily life. Impairment in many of
these functions may exist because of brain abnormalities that
cannot be detected on CT or MRI scans. Therefore, neuropsychological
assessment is a procedure with a unique purpose; it can be used
to reveal or diagnose brain dysfunction when no structural brain
abnormalities can be seen.
Furthermore, when structural abnormalities have been found, neuropsychological
assessment provides a way to determine what functions may be
impaired because of the structural defects, and to determine
the degree to which they may be impaired.
What Is A Neuropsychologist?
A neuropsychologist is a licensed psychologist specializing
in the area of brain-behavior relationships. Although a neuropsychologist
has a doctoral degree in psychology, he or she does not just
focus on emotional or psychological problems. The neuropsychologist
has additional training in the specialty field of clinical
neuropsychology. That means a neuropsychologist is educated
in brain anatomy, brain function, and brain injury or disease.
The neuropsychologist also has specialized training in administering
and interpreting the specific kinds of tests included in your
neuropsychological evaluation. As a part of the required education,
a neuropsychologist also has years of practical experience
working with people who have had problems involving the brain.
An official, more detailed definition of a clinical neuropsychologist
has been approved by the National Academy of Neuropsychology
and can be viewed at the NAN website (www.NANonline.org).
What tests are used?
The standardized tests used in a neuropsychological evaluation
typically assess functioning in the following areas: attention
and memory, problem-solving and other complex abilities, visual-spatial
functions, language functions, sensoryperceptual functions,
and motor functions.
Assessment of academic skill development and emotional functioning,
while not exclusive to neuropsychological evaluation, is typically
performed, as well. The perspective of the neuropsychologist
is frequently requested to understand subtle brain-related
factors involved in academic failure or impaired emotional
functioning, even when no biological causes are suspected.
However, the specific areas assessed depend upon the referral
questions presented. An interview with the individual and/or
family members is typically included. Observations in other
settings, such as school or hospital, and review of school/medical
records also may be included in the evaluation process.
What
is the Outcome?
The product or outcome of a neuropsychological evaluation is
aconclusion or set of conclusions made about the individual's
functioning. If requested, the product also may include specific
recommendations to guide treatment or otherwise enhance the individual's
functioning. The conclusions and recommendations are developed
by integrating information obtained from the standardized testing,
interviews, records and other observations.
