Brain-Training Treatment for Long COVID in Older Adults

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.

Inclusion Criteria:prior history of COVID-19 based on Centers for Disease Control and Prevention (CDC) guidelines including a positive laboratory test (e.g., nucleic acid amplification test) or a positive rapid testage ≥ 55 years oldcurrent self-reported cognitive symptoms persisting after the acute phase of the illness (i.e., >4 weeks after COVID-19 symptom onset) that cannot be explained by alternative diagnosesevidence of subjective cognitive impairment with a Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog) Perceived Cognitive Impairment (PCI) Subscale Score of ≤ 40Telephone Interview for Cognitive Status (TICS) ≥ 27fluent in Englishoff psychiatric medications or on a stable dose for at least 1 month prior to commencing the study with no intention to change dose prior to completion of the study.Exclusion Criteria:history of neurological disorder or other medical condition with potential to impair cognitive functioning or interfere with study participation (e.g., epilepsy, stroke, dementia, head trauma followed by persistent neurological deficits or known structural brain abnormalities)prior diagnosis of Mild Cognitive Impairment (MCI) or Mild Neurocognitive Disorder unrelated to the participant's history of COVID-19history of significant psychiatric illness per Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), criteria that may interfere with study participation or confound results (e.g., schizophrenia or other psychotic disorder, bipolar and related disorders, major depressive disorder with psychotic features, personality disorder)history of significant neurodevelopmental condition that may interfere with study participation or confound results (e.g., intellectual disability, autism spectrum disorder)alcohol or other substance use disorder within the past 2 yearssignificant sensory or motor impairments (e.g., blindness) that may interfere with the ability to complete neuropsychological measures or engage in the intervention
