Neurpsychological Evaluations

 

Neuropsychological Testing


In our practice, we use a wide range of standardized neuropsychological tests. These tasks have been designed so the performance on the task can be linked to specific neurocognitive processes. These tests are typically standardized, meaning that they have been administered to a specific group (or groups) of individuals before being used in individual clinical cases. The data resulting from standardization are known as normative data. After these data have been collected and analyzed, they are used as the comparative standard against which individual performances can be compared.


Neuropsychological evaluation (NPE) is a testing method through which a neuropsychologist can acquire data about a subject’s cognitive, motor, behavioral, linguistic, and executive functioning. In the hands of a trained neuropsychologist, these data can provide information leading to the diagnosis of a cognitive deficit or to the confirmation of a diagnosis, as well as to the localization of organic abnormalities in the central nervous system (CNS). The data can also guide effective treatment methods for the rehabilitation of impaired patients.

 

NPE provides insight into the psychological functioning of an individual, a capacity for which modern imaging techniques, such as CT and MRI scans, have only limited ability. However, these tests must be interpreted by a trained, experienced neuropsychologist in order to be of any benefit to the patient. These tests are often coupled with information from clinical reports, physical examination, and increasingly, pre-injury and post-injury self and relative reports. Standing alone, each neuropsychological test has its own strengths and weaknesses in areas such a its validity, reliability, sensitivity, and specificity. However, through comprehensive testing, the utility of NPE has become increasingly powerfu

NPE is useful for measuring many types of cognitive functions, including:


Executive functioning
Academics & Intellectigence
Language processing
Processing deficiencies
Attention & Memory
Verbal & Visual learning
Sensory-perceptual functions
Motor speed and strength
Motivation/Symptom validity
Personality assessment
