What is CNS Vital Signs?
CNS Vital Signs is a reimbursable assessment procedure that utilizes scientifically validated, objective, and reliable computerized neuropsychological tests to evaluate the neurocognitive status of patients and covers a range of mental processes from simple motor performance, attention, memory, to executive functions. CNS Vital Signs also contains over 50 well known evidence-based clinical and quality measure (behaviors, symptoms, comorbidities, quality-of-life) rating scales. Immediately following the assessment, the software automates a standardized scoring of the patient assessment eliminating variability and rater bias. The assessment platform auto-scores and generates user-friendly reports with summary dashboards, individual responses, and longitudinal views. The neurocognitive report presents the raw test scores, domain scores with a comparison of age-adjusted norms, and an overall neurocognition index.The standardized presentation of the report and its data supports the clinicians' evaluation and management activities.
The use of CNS Vital Signs with other proven neurological exams gives the clinicians a robust view of the patient's neurocognitive status. The assessment platform lends an added dimension to the patient evaluation and generates useful data that can guide one's decisions about ongoing treatments or the need for additional information or whether a referral is warranted.
How is CNS Vital Signs used?
The clinical applications for CNS Vital Signs can be summarized in terms of seven prototypical situations:
How do I access and download the CNS Vital Signs local software assessment platform?
When you register with CNS Vital Signs you can download and install the software, you will be given five fully functional free test administrations to trial and train on the assessment platform.

What computerized neuropsychological tests are used in CNS Vital Signs?
The core CNS Vital Signs "BRIEF-CORE" neurocognitive assessment battery consists of seven subtests: Verbal Memory (VBM), Visual Memory (VIM), Finger Tapping (FTT), Symbol Digit Coding (SDC), Stroop Test (ST), Shifting Attention Test (SAT) and the Continuous Performance Test (CPT). There are three additional tests Perception of Emotions (POET), Non-Verbal Reasoning (NVRT), 4-Part Continuous Performance (FPCPT) developed for brain and behavioral specialists. Email or call support for more information about the other tests available. Tests and Domains PDF
What does each subtest of CNS Vital Signs measure?
The CNS Vital Signs "BRIEF-CORE" neurocognitive assessment captures an objective view of eleven basic brain functions: composite memory, verbal memory, visual memory, executive function, processing speed, psychomotor speed, reaction time, complex attention, cognitive flexibility, simple visual attention, and motor speed. The "BRIEF-CORE" battery consists of seven subtests which in different combinations compose the above eleven cognitive domains. CNS Vital Signs includes parallel tests of verbal memory (word list learning) and visual memory (figure learning). The tests are virtually identical, but one uses words as stimuli, the other, geometric shapes. The Finger Tapping Test generates relevant data about fine motor control, which is based on motor speed as well as kinesthetic and visual-motor ability. The Symbol Digit Coding Test generates processing speed data and is included in a composite score for psychomotor speed. The Stroop Test gives important data about three levels of reaction time (simple, complex, Stroop) or, to be more precise, information processing speed. The Shifting Attention Test measures a subject's executive functions (rules, categories, rapid decision making) or their ability to shift from one instruction set to another quickly and accurately. The Continuous Performance Test is a measure of vigilance or sustained attention or attention over time.
What is the normative structure of CNS Vital Signs?
The original seven tests of the CNS Vital Signs neurocognitive assessment platform have been normed in a large sample (n=1662) of normal individuals, from age 8 to 90. "Normals" are defined as healthy individuals, with no active medical condition, and with no history of neurological or psychiatric disorders. Normals may be on stable doses of medications for well-controlled medical conditions, like hypertension or arthritis, but not on any psychotropic medication.
How do I code and get reimbursed for my services?
The CNS Vital Signs procedure codes have been reimbursed by Medicare, Medicaid and almost all private insurance companies when billed using the appropriate ICD-10 codes and modifiers. Most public payer reimburses any licensed practitioner e.g. MD, DO, PhD, PsyD, NP, PA, however, a few health plans reimburse only licensed psychologists, neurologists, psychiatrists or developmental/behavioral specialists. GO TO the Reimbursement section of the CNS Vital Signs website for more detailed reimbursement and coding information.
Have there been any concurrent validity studies comparing CNS Vital Signs to conventional tests?
Yes, refer to "Reliability and Validity of a computerized neurocognitive test battery, CNS Vital Signs", Arch Clin Neuropsychol. 2006 Oct;21(7):623-43.
How soon can I retest the same person on CNS Vital Signs?
This is a KEY ADVANTAGE as CNS Vital Signs was designed for serial administration. The words and symbols in the test are auto-randomized from a large bank of potential stimuli generating an unlimited number of alternate forms. This minimizes potential learning effects in serial administration. Tests other than memory tests are routinely administered several times a day in research settings.
How do I know if the neurocognitive assessment is valid?
The CNS Vital Signs Validity Indicator (VI) is a guideline identifying the possibility of an invalid test or domain score. When reviewing a report, a "No" in the VI column suggests the clinician should evaluate whether or not the test subject understood the test, put forth their best effort, or has a clinical condition requiring further evaluation. The Validity Indicator alerts the clinician to the possibility of an invalid test allowing the clinician, examiner or testing technician to question the testing subject: Do the testing results reflect an understanding of the test and the instructions? Did the testing subject put forth their best effort? Did they get a good night's sleep? Does the subject have poor vision and need their glasses? Do the results suggest willful exaggeration, e.g., malingering?
How is the CNS Vital Signs Validity Indicator determined?
The "Validity Indicator" scoring algorithm is based on research presented (Detecting Invalidity In Neurocognitive Tests) at International Society for CNS Clinical Trials and Methodology (ISCTM) in 2009. The poster is available on the CNS Vital Signs website.
