This research is being done to collect preliminary data on the potential of computerized "brain-training" exercises for treating Long COVID symptoms in older adults. The investigators hypothesize that computerized brain-training will be an acceptable and feasible intervention for treating Long COVID symptoms in older adults. The investigators also expect to provide initial evidence that computerized brain-training has potential for improving thinking, mood, and other aspects of everyday functioning in older adults with Long COVID.
Some patients who contract coronavirus disease 2019 (COVID-19), especially older adults, show lingering neuropsychiatric symptoms such as cognitive impairment, brain fog, and depression. These neuropsychiatric symptoms-commonly referred to under the umbrella term "Long COVID"-are debilitating and may last for months or even years after viral infection. The purpose of the present study is to help address this public health crisis by determining whether computerized "brain-training" treatment has potential for improving thinking, mood, and other aspects of functioning in older adults with Long COVID. More specifically, the first aim is to determine the acceptability and feasibility of using brain-training treatment in individuals with Long COVID. The second aim is to evaluate for potential efficacy by determining whether brain-training treatment appears to improve cognitive function, mood, and other aspects of daily functioning in Long COVID.

The computerized cognitive remediation intervention ("NeuroFlex") consists of a series of gamified tasks (e.g., BrainHQ, Neurogrow, Ultimate Word Master) administered via computer tablet. The intervention provides both "bottom up" training to improve basic processing of sensory stimuli and "top down" training to improve executive functions. Participants will be asked to complete approximately 7.5 hours a week of computer treatment over an approximately 6-week period, for a total of approximately 45 hours of treatment. The treatment will be completed remotely by the participant within their own home or other private location that is most convenient for the participant.

RECRUITINGTreatment Acceptability/Adherence Scale (TAAS)
Treatment acceptability and adherence as measured by the TAAS Total Score; higher scores on this self-report measure indicate greater treatment acceptability and adherence
Time frame: The investigators will evaluate TAAS Total Score at the outset of treatment (expected/anticipated acceptability and adherence) and at post-treatment (6 weeks)
Credibility/Expectancy Questionnaire (CEQ)
Treatment credibility and expectancy as measured by the CEQ Total Score; higher scores on this self-report measure indicate greater treatment credibility and expectancy
Time frame: The investigators will evaluate CEQ Total Score at the outset of treatment (to assess initial perceptions of treatment credibility) and at post-treatment (6 weeks)
System Usability Scale (SUS)
Usability of the intervention as measured by the SUS Total Score; higher scores on this self-report measure indicate greater perceived usability
Time frame: The investigators will evaluate SUS Total Score at the outset of treatment (to assess initial perceptions of treatment usability) and at post-treatment (6 weeks)
Feasibility (proportion of subjects who agree to participate in the offered treatment, complete assigned exercises, and complete the entire treatment regimen)
Feasibility will be assessed according to the following criteria: 1) at least 80% of eligible subjects offered the treatment agree to participate; 2) subjects will complete at least 80% of assigned treatment exercises; 3) at least 80% of participants who start the treatment will finish it.
Time frame: Our feasibility criteria will be assessed by calculating percentages at the conclusion of the study
Trail Making Test Part B
Set-shifting abilities as measured by time to complete the Trail Making Test Part B in seconds; lower scores indicate better set-shifting performance
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Time frame: The investigators will evaluate change in time (seconds) to complete the Trail Making Test Part B at post-treatment (6 weeks) relative to pre-treatment (baseline)
Montgomery-Asberg Depression Scale (MADRS)
Depressive symptoms as measured by the Total MADRS Score; lower scores indicate less depressive symptoms
Time frame: The investigators will evaluate change in Total MADRS Score at post-treatment (6 weeks) relative to pre-treatment (baseline)
World Health Organization Disability Assessment Schedule (WHODAS)
Functional disability as measured by the Total WHODAS Score; lower scores indicate less functional disability
Time frame: The investigators will evaluate change in Total WHODAS Score at post-treatment (6 weeks) relative to pre-treatment (baseline)
Everyday Cognition (ECog)
Subjective cognitive concerns as measured by the Total ECog Score; lower scores indicate less subjective cognitive concern
Time frame: The investigators will evaluate change in Total ECog Score at post-treatment (6 weeks) relative to pre-treatment (baseline)
Verbal Fluency
Verbal generativity as measured by the total number of words produced according to pre-specified rules; higher scores indicate better verbal generativity performance
Time frame: The investigators will evaluate change in total number of words produced at post-treatment (6 weeks) relative to pre-treatment (baseline)
Stroop Color and Word Test
Inhibitory control as measured by total correct responses on the inhibition condition of the Stroop Test; higher scores indicate better inhibitory control performance
Time frame: The investigators will evaluate change in total correct responses at post-treatment (6 weeks) relative to pre-treatment (baseline)
Fatigue Assessment Scale (FAS)
Fatigue as measured by the Total FAS Score; lower scores indicate less fatigue
Time frame: The investigators will evaluate change in total FAS Score at post-treatment (6 weeks) relative to pre-treatment (baseline)
California Verbal Learning Test (CVLT)
Verbal memory as measured by the total number of words correctly recalled on the long delayed free recall trial; higher scores indicate better episodic memory performance
Time frame: The investigators will evaluate change in long delayed free recall at post-treatment (6 weeks) relative to pre-treatment (baseline)
Short Physical Performance Battery (SPPB)
Physical performance as measured by the Total SPPB Score; higher scores indicate better physical performance.
Time frame: The investigators will evaluate change in physical performance at post-treatment (6 weeks) relative to pre-treatment (baseline)
