Summary

This two-year study will evaluate the feasibility and safety of an exercise + cognitive training program to improve neurological symptoms of long-COVID. This is a two-phased trial: 1) an exercise phase and 2) a cognitive training phase. The exercise phase will be an aquatic based exercise program. A combination exercise + memory training programs designed for persons with cognitive impairment have significantly improved memory more than other single intervention groups (exercise only, cognitive training only) and given the success of combination training programs with healthy adults, it is important to adapt these programs for persons with neurological symptoms of long-COVID.

Detailed description

The primary research question of the proposed study is this: Is a water-based exercise + cognitive training (WATER+CT) intervention for Veterans with neurological manifestations of long-COVID feasible? The investigators address the need to enhance recovery in this vulnerable population through an innovative multi-component training program that has successfully been used in other cognitively impaired populations. The aims of the proposed research include: 1) demonstrate feasibility as shown by good recruitment and retention rates and stakeholder ratings; 2) evaluate appropriateness of suggested inclusion and exclusion criteria; 3) evaluate acceptability of water-based physical exercise + cognitive training interventions; 4) assess ability of selected outcome measurement techniques to determine the efficacy of water-based physical exercise + cognitive training; and 5) examine outcome "moderator" and "mediator" measurement techniques. These aims will be tested in a single-blind randomized controlled pilot trial that will establish the feasibility of WATER+CT. This trial will include 50 Veterans, age 18 - 89, experiencing neurological manifestations of long-COVID, with half randomized to WATER+CT and half to usual care. WATER+CT consists of two phases: 1\) an exercise training phase and 2) a cognitive training phase. The exercise training (i.e., WATER) consists of a six-month long individualized exercise program of water-based exercises. During this phase, Veterans will come to thrice-weekly group sessions at Aquatic Therapy Center at VA Palo Alto Health Care System (VAPAHCS). After completion of the exercise program, Veterans will begin classroom-based cognitive training at VAPAHCS for up to two months. The CT is based on an efficacious training program that is structured around two components, pre-training, and mnemonic training, both of which have been used successfully in persons with cognitive impairment. Veterans randomized to the UC control condition will receive educational materials about brain health in addition to their usual care, which is the care they would typically receive in the VA. Assessments of adherence will be administered throughout treatment and measures of feasibility will be completed post-treatment. Participants will complete a variety of neuropsychological measures taping into areas of cognition such as attention, executive functioning, and memory. Participants will also undergo physical fitness assessments including a 6-minute walk test and an exercise treadmill test. To study possible predictors of response to treatment, the investigators will also collect physiological (VO2 max), biological (inflammatory markers and BDNF plasma levels), and genetic data (APOE and BDNF genotypes) from these participants. The investigators hope to provide initial evidence of the feasibility of a water-based exercise training + cognitive training program and provide foundational support for a future program development targeting enhanced recovery in Veterans with neurological manifestations of long-COVID.

Interventions

Type	Name	Description
BEHAVIORAL	WATER+CT	This is an 8-month long two phase intervention. The first phase consists of 6 months of thrice weekly pool-based exercise occurring at VA Palo Alto. After completion of the 6 month long pool based exercise, participants transition to ten sessions of cognitive training that will occur over 2 months at the VA Palo Alto.
BEHAVIORAL	Usual Care	This condition involves receipt of educational materials about brain health and healthy lifestyles as well as regular contact with study staff.
