addressing cognitive fog in long-covid-19 patients

Conditions: Cognitive Impairment; Long COVID

Summary: this study will assess two options to help patients better manage the cognitive fog and emotional distress that may be associated with having long-covid. long-covid is post-covid conditions or symptoms lasting more than four weeks after infection. clinicians from the upmc long-covid clinic leading this study are evaluating the utility of computer-based evaluation of covid-related cognitive fog and the helpfulness of two intervention strategies to treat moderate cognitive impairment using a randomized trial. the two intervention strategies include 1) a standardized dosing of amphetamine/dextroamphetamine medication that has been used to improve cognitive fog; and 2) a digital behavioral tool with an embedded health coach that is used on a mobile phone.

eligible participants will be randomized to one of two arms. one intervention targets cognitive fog associated with depression (rxwell mobile app), the other the cognitive fog directly (amphetamine-dextroamphetamine medication). two weeks after randomization, participants are contacted by study staff to complete the gad7. participants who are randomized to rxwell will be offered assistance if they were not able to download the app on their own. participants who are randomized to receive the stimulant will also complete a stimulant drug side effect rating scale to determine if the participant has any effects from the medication. all participants will complete computerized neurocognitive assessments (impact, and braincheck) and other study measures (moca (screen, 1.5 and 3 months), patient health questionnaire, generalized anxiety disorder measure, satisfaction with life scale, pcl-5 post traumatic stress disorder checklist, adhd symptom screener, and sheehan disability scale) at baseline, 1.5 (interim) and 3 months after randomization. the study measures, other than the neuro-cognitive assessments, will be completed via redcap.
