The purpose of this study was to test the reproducibility of the current data set. It was hypothesized that older adults’ scores on the Repeatable Battery for Assessment of Neuropsychological Status (RBANS) would decrease from their initial visit to their one year follow-up visit and that greater overall age is associated with worse performance. Overall, the older adults with a follow-up visit in this study experienced greater decline on the RBANS DMI than on the RBANS total scaled score. There seems to be a negative trend in which individuals with higher first-visit VCI scores experience greater improvement on the first trial of the motor task with the non-dominant hand. The same trend can be seen in DMI scores where higher initial DMI scores are associated with greater improvement on the first non-dominant hand trial of the motor task. This initial trend suggests that visuospatial scores have an association with long-term change in the motor task. The number of participants in this data set were limited, thus more data will be needed to increase confidence in conclusions about these relationships in the future.

Survivors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) often experience chronic symptoms that include fatigue, shortness of breath, and brain fog. The collection of ongoing post-COVID-19 symptoms have been classified as Post-Acute Sequela of SARS-CoV-2 (PASC). Older adult patients are especially susceptible to experiencing PASC related complications and have a high risk for long-term cognitive impairment symptoms. Definitions for categorizing PASC- associated cognitive impairment and neuropsychological assessments used to evaluate cognitive impairment are inconsistent between studies examining older adults. This systematic review aims to identify which neuropsychological tests best identify cognitive impairments associated with PASC and suggest a guide to standardize the measurement of PASC-related cognitive impairments. Through a literature search using PubMed, we included within this review 14 studies that fulfilled our inclusion and exclusion criteria evaluating middle-aged and older adult populations affected by PASC-associated cognitive impairments. The majority of the studies used tests designed to screen for general cognitive function to test for the prevalence of cognitive impairment, with the most common one being Montreal Cognitive Assessment (MoCA), followed by MMSE and TICS. MoCA reported the highest prevalence of the general cognitive screeners which suggests higher sensitivity and specificity. Telephone Interview for Cognitive Status (TICS) demonstrated similar scores as MoCA despite administration being remote while MMSE identified the lowest prevalence. Four studies also used domain-specific cognitive evaluations and reported instances of cognitive impairment in individuals who had previously tested healthy. Furthermore, the results gathered in this review were stratified based on disease symptom severity. This review identifies MoCA to be better suited for evaluating general cognitive impairment in older adults. TICS has the added utility in being able to access a wider range of older adults through remote screening. Disease severity must be clearly defined to allow better comparisons between studies and allow for standardization. Early identification of PASC-associated cognitive impairment in middle-aged and older adults can be performed using general cognitive function evaluations and administering a baseline cognitive evaluation one month after infection is suggested.
