RECOVER-NEURO: Platform Protocol to Measure the Effects of Cognitive Dysfunction Interventions on Long COVID Symptoms

RECOVER-NEURO: A Platform Protocol for Evaluation of Interventions for Cognitive Dysfunction in Post-Acute Sequelae of SARS-CoV-2 Infection (PASC)

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 328 (actual)
• Sponsor: Duke University · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

This platform protocol is designed to be flexible so that it is suitable for a wide range of settings within health care systems, for remote settings, and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, randomized, controlled platform trial evaluating potential interventions for PASC-mediated cognitive dysfunction. The hypothesis is that PASC associated dysfunction in cognitive domains, such as executive function and attention, may be improved by interventions that selectively focus on enhancing those domains.

Detailed description

Participants will be randomized to one of the intervention appendices that are actively enrolling at the time of randomization. Intervention appendices may be added or removed according to adaptive design and/or emerging evidence. Various interventions will be studied.

Conditions

• Long COVID
• Long COVID-19
• Long COVID19

Interventions

Type	Name	Description
OTHER	BrainHQ/Active Comparator Activity	BrainHQ platform provides a set of cognitive activities, like puzzles and games, that are cognitively stimulating and actively engage participants but do not continuously and adaptively challenge them. These activities are designed to be a face-valid, active comparison approach to cognitive therapy, thus participants are blinded, attention time is matched, and overall user experience is identical to the active arms.
OTHER	BrainHQ	BrainHQ is an online cognitive training program, and has been used to improve cognitive function among persons with cognitive impairment based on principles of neuroplasticity.
OTHER	PASC CoRE	PASC CoRE is a manualized, adaptable cognitive rehabilitation intervention adapted from Goal Management Training and other evidence based programs that improve attention and executive functions, among other cognitive domains.
DEVICE	tDCS-active	Transcranial direct current stimulation (tDCS) will use a device specifically for home-based use. This device delivers a weak electrical current of 2.0 mA passed through two electrodes placed on the scalp to target the dorsolateral prefrontal cortex region of the brain. The electrodes are single-use for each session and can be attached to a headset by snapping into place. The device has a user-friendly interface and a large-button keypad, making it is easy to use at home.
DEVICE	tDCS-sham	tDCS devices used in the sham arm will be pre-programmed to deliver the same ramp up/down at the beginning/end of the 30-minute period as the active arm, except with no current otherwise delivered during the session.
