Neuropsychological Testing and Assessment
What is neuropsychology?
Neuropsychology is a specialty field that joins the medical fields of neurology, psychology and psychiatry. Neuropsychology involves determining how well the brain is working when it is disrupted by a brain injury or psychological disorder. A neuropsychological assessment is a comprehensive test of a wide range of mental functions including behavior.
What mental functions are assessed in a neuropsychological exam?
If you are undergoing a neuropsychological assessment, the mental functions tested include:
- General intellect.
- Reading/reading comprehension.
- Language usage and understanding of what others say.
- Processing speed.
- Learning and memory.
- Executive functions, which are higher-level skills you use to organize and plan, manage your time, problem solve, multi-task, make judgments and maintain self-control.
- Visuospatial skills.
- Motor speed and dexterity.
- Mood and personality.
Why has a neuropsychological assessment been requested?
A neuropsychological assessment can be requested for a number of reasons including:
- To help with diagnosis: Test results are sometimes used to help understand the cause of problems with your thinking and understanding. For example, test results might be used to determine if your cognitive (mental) changes are due to normal aging, a neurological illness, depression, anxiety or other causes. Your healthcare provider can then use the results of your neuropsychological examination along with the results of other tests, such as brain scans, EEGs, and blood tests, to arrive at a diagnosis that will help to guide your healthcare.
- To determine cognitive strengths and weaknesses: In some cases, a healthcare provider may order tests if you’ve had a known neurological event or injury, such as a stroke or traumatic brain injury, to find which cognitive functions have changed and how much they have changed.
- To establish a baseline: In some instances, an exam is performed before and after a medical or surgical treatment to determine if cognitive abilities were affected by the intervention. Re-examination at some point after the baseline can also demonstrate how well you’re recovering from a stroke or traumatic brain injury and whether or not you’re ready to return to work, resume driving or take on other duties.
- To help plan a treatment or other intervention: Test results can be used to identify which cognitive abilities should be the focus of rehabilitation if you’ve had a brain injury. Results also help therapists determine which strengths might be able to compensate for weaknesses. The evaluation can provide the basis for making decisions and/or adjustments to school or work schedules and determine the skills to work on that are most important to you.
How will I know if my cognitive abilities have changed if I have not had an exam in the past?
Some cognitive abilities tend to be very stable despite neurologic illnesses or injuries. Those abilities often provide an estimate of the level of your other cognitive abilities if no injury or illness had occurred. Your results will be compared to the pattern of results associated with various illnesses or injuries to help determine if changes have occurred.
What common complaints might signal the need for a neuropsychological test?
