NEUROPSYCHOLOGICAL EVALUATIONS
A neuropsychological evaluation assesses how one's brain functions post-traumatic brain injury. The neuropsychological evaluation involves an interview and the administration of tests. The tests are typically pencil and paper type tests. Some tasks might be self-reports meaning that the patient completes them with assistance from a technician. The tests require administration by a neuropsychologist or trained, skilled psychometrist.
Neuropsychological tests evaluate functioning in several areas, including intelligence, executive functions (such as planning, abstraction, conceptualization), attention, memory, language, perception, sensorimotor functions, motivation, mood state and emotion, quality of life, and personality styles.
A complete evaluation generally takes between two and five hours to complete but can take up to eight hours, depending on the complexity of the issues to be addressed by the evaluation and the patient's condition (for example, fatigue, confusion, and motor slowing can extend the time required for an assessment). Occasionally, it is necessary to complete the evaluation over two or more sessions. In general, the clinician attempts to elicit the patient's best possible performance under optimal conditions.
These are not tests that one can study for, but there are several things that one can do to facilitate the evaluation:
• The patient should bring a current list of ALL medications and doses (because medicines may frequently change for some persons, it is vital to make sure the list is up to date)
• If the patient has difficulty providing information about their history, it is helpful for a family member or friend to accompany them (for at least part of the clinical interview).
• It is helpful if the patient can provide records of previous neurodiagnostic testing (e.g., brain scans such as CT or MRI scans) and results from previous neuropsychological evaluations if completed at another hospital or institution.
The neuropsychologist's goal is to get the best possible picture of the patient's current functioning. Several things can interfere with this goal, such as if the patient is:
• Fatigued or has sudden, unexpected "sleep attacks";
• Not motivated to put forth their best effort;
• Very emotionally distraught or has a mental illness;
• Under the influence of medications or illicit substances which interfere with cognitive functioning;
• Experiencing frequent changes in the ability to move.
Patients should let the examiner know if they anticipate that any of these issues will interfere with the evaluation.
