Neurocognitive Testing: What Is It & Is It Right for You?

    • November 25, 2019

    Oftentimes, impaired cognitive function comes with age. Yet, there are many other factors which could play into mental acuity, including diet, exercise, and hormone levels.

    When doctors have a full understanding of patient health, including both their physical biomarkers and brain function, they are better able to understand the complex interplay among these physical and mental aspects of wellness to make more informed care decisions.


    What is Neurocognitive Testing?

    Neurocognitive testing is a noninvasive method for measuring brain function. It evaluates specific cognitive abilities, including memory, fine motor control, and recognition, among others. Various abilities are linked to different areas in the brain. For instance, organization skills are linked to the frontal lobes, while memory skills are concentrated in the temporal lobes.
    Assessing cognitive strengths and weaknesses gives doctors a comprehensive picture of how your brain is functioning overall. Find out more about this powerful testing method and why it’s used below.


    What Do Neurocognitive Tests Measure?

    Neurocognitive tests are robust and measure a broad range of functions. At Cenegenics, these tests are broken down into six individual assessments, each of which measures a specific brain function:

    1. Verbal Memory Test: The verbal memory test measures a subject’s ability to recognize, remember, and retrieve words. Subjects are given 15 words to remember, and are asked to recognize them in a field of 15 distractors. There are two parts to the test: immediate, and delayed, which is given later. A low score on this section indicates verbal memory impairment.
    2. Visual Memory Test: This test assesses a subject’s ability to recognize, remember, and retrieve geometric figures. The format is the same as that of the verbal memory test, with both immediate and delayed segments and 15 figures in total.
    3. Finger Tapping Test: This test measures motor speed and fine motor control ability. The subject is instructed to perform three rounds of tapping with each hand. Oftentimes, subjects are quicker with their dominant hand. A low score could indicate motor slowing.
    4. Symbol Digit Coding: The SDC test measures a subject’s speed of processing. It employs the use of several cognitive processes at once, including visual scanning, perception, memory, and motor functions. Errors could indicate confusion, misperception, impulsive responding.
    5. Stroop Test: The stroop test measures reaction times and mental flexibility. It is used to test impulsivity and inhibitor control. Prolonged reactions are indicative of cognitive slowing or impairment.
    6. Shifting Attention Test: This test measures executive function, or a subject’s reaction to set shifting and simultaneous task management. Another test of mental flexibility, the exercise requires subjects to adjust their responses to rules that change at random. Top scores include high correct responses, short reaction time, and few errors. This test can uncover attention deficit.
    7. Continuous Performance Test: The CPT assesses sustained attention and choice reaction time. Under normal circumstances, subjects tend to score near-perfect scores on this test. A long response time could indicate cognitive slowing or impairment.

    Based on the scores of the exercises above, patients receive a score for each of the following domains:

    • Neurocognition index
    • Composite memory
    • Verbal memory
    • Visual memory
    • Psychomotor speed
    • Reaction time
    • Complex attention
    • Cognitive flexibility
    • Processing speed
    • Executive function
    • Simple visual attention
    • Motor speed

    There are also embedded measures built in to the assessments to evaluate their validity. These help to evaluate whether a subject could be manipulating the test score, either intentionally or as a result of not understanding the test instructions.


    Why Do the Findings Matter?

    Neurocognitive tests have many benefits. Brain scans and surgeries can be costly, time-intensive, and invasive, but neurocognitive tests don’t take much time to complete and pose no risk to patient health. Plus, the scores from these assessments can accurately measure brain function, which may allow for diagnosis of issues or impairments.

    Even the slightest impairments can be evaluated with millisecond precision to provide immediate clinical insight into a patient’s impairments or deficits. Doctors can then use these impairments to look for patterns, which help to identify causes or any other underlying conditions.

    Neurocognitive tests are also useful for establishing a baseline of cognitive wellness. Whether an issue is detected or the patient scores high in all test areas, their present answers provide a baseline which clinicians can reference in the future. This will allow them to better manage clinical conditions and treatments. For example, comparing the scores of future tests to the baseline results will allow doctors to determine whether the patient is responding well to treatments, rehabilitation efforts, or even simple lifestyle tactics such as exercise and dietary changes to promote better cognitive wellness.

    Modern neurocognitive testing is extremely sensitive and objective, and shows the ability to produce consistent results. Ultimately, doctors who provide this service can achieve a more comprehensive understanding of patient health, with the ability to measure not only physical wellness but also brain health.


    Is Neurocognitive Testing Right for You?

    Changes in cognition are often associated with natural changes brought on by aging. Yet, figuring any cognitive impairments are unavoidable parts of aging is a dangerous assumption to make. While aging is a natural process, it’s one that can be managed through personalized and comprehensive care.

    If you’ve been experiencing any differences in your cognitive abilities – no matter your age – you could be a good candidate for neurocognitive testing. In particular, anyone with the following symptoms should consider an assessment:

    • Brain fog
    • Recurring headaches
    • Mood changes or depression
    • Difficulty concentrating
    • Memory loss
    • Mood swings
    • Trouble multitasking

    A neurocognitive test could shed light on any underlying issues and give doctors the ability to pinpoint issues early on, when treatments are most likely to be effective. They can also observe any areas of cognitive underperformance which could be improved with simple lifestyle adjustments. No matter what your circumstances may be, this testing can uncover illuminating results which have the potential to improve your life and preserve your mental acuity, now and into the future.

    Neurocognitive testing may sound intimidating, but this noninvasive assessment simply gauges key brain functions to measure mental acuity. With a series of simple tests, clinicians are able to look for any impairments in the areas of memory, motor skills, processing speed, attention, and reaction time, among others. These insights can uncover potential problem areas, but also help to provide a roadmap for treatment or lifestyle management techniques, if needed.
