Step 1: On an Internet-connected computer, the patient takes a 30-minute test that includes: a) questions about patient background, pertinent medical history, and computer familiarity; b) neurocognitive subtests of reaction time, processing speed, memory, and attention/executive functioning; and c) an optional mental status examination completed at the provider's discretion.

Step 2: Immediately following the test, the provider can generate a report based on cross-sectional normative data for the neurocognitive subtests. The report includes: a) identifying information and chief complaint (if applicable); b) comparison of neurocognitive test results to healthy controls; c) report of problems with chronic pain; d) report of mental status (if applicable); e) provider-generated comments and observations; and f) cautions regarding test interpretation based on pertinent data.

Step 3: If mental status was not assessed initially, the provider can complete a mental status exam at a later time. The HeadMinder Mental Status Exam is easily and quickly compiled using a mouse-based "point-and-click" interface. Results are presented in a narrative format and are added to the CSI report.

Step 4: Following a second test administration, the provider can generate a longitudinal report using specialized statistics that allow for comparison of results with earlier CSI administrations. Statistics directly compare each patient's scores to his/her own baseline, not group averages. This enables the provider to determine whether neurocognitive functioning is improving, remaining stable, or deteriorating. Mental status data can also be compared to earlier levels of functioning to aid in diagnostic and/or treatment decisions.

Step 5: Additional test administrations allow for further monitoring of significant changes in neurocognitive/neurobehavioral functioning.

Innovation
•	Patented proprietary technology.
•	Providers can administer the CSI and access CSI test records from any Internet-connected PC.
•	Using specialized statistics, the CSI longitudinally measures significant change in neurocognitive functioning of neurologically compromised patients.
•	The CSI allows clinicians and researchers to longitudinally assess the efficacy of pharmaceutical interventions.
•	Specialized normative statistics tailored to the number of tests taken reduce the influence of practice effects and other sources of error. Multiple equivalent alternate forms are also used to control for practice effects.
•	Confidentiality and the "patient-provider" relationship are maintained. Only registered professionals can view a patient's report.
